Embodiment

Describe prior art ALFDEX separator now with reference to Fig. 1 of accompanying drawing to 12, and emphasize to be placed on those aspects improved by the present inventor of the prior art separator especially.

At Fig. 1 of accompanying drawing, in 2,8,9 and 10, show some views of the prior art ALFDEX separator 2 assembled. It will be understood by persons of ordinary skill in the art that prior art separator 2 comprises the rotor shell 4 of general cylindrical, it works for receiving and is separated some fuel-displaced internals from the gas of the releasing being directed to described rotor shell 4.

One end of cylindrical housing 4 is provided with the annular shoulder 6 of setting, and it limits the fluid intake 8 of separator 2. It is to be understood that therefore, release from crankshaft shell and need the gas therefrom removing oil to enter separator 2 by fluid intake 8.

Aperture 10 in the cylindrical wall of rotor shell 4 is provided for the outlet that Purge gas is sent to the other housing 12 being associated with valve cell 14 (see Fig. 1) from the inside of rotor shell 4. The valve that valve cell 14 comprises the stream for controlling the Purge gas from separator 2 is arranged. The details of the operation of valve cell 14 will not describe herein. But, as from Fig. 1 by apparent, the outside of rotor shell 4 is designed to mate with the housing 12 of valve cell 14 especially so that two housings 4,12 combinations limit the internal space of the internals being applicable to receiving valve unit 14 between described housing 4,12. Two housings 4,12 are fixed to by traditional threaded fastener 16 to be gone up each other. Therefore it will be appreciated that specific valve cell housing 12 only can use together with the concrete rotor shell 4 with necessary mating feature.

With reference to Fig. 1, it will be seen that the housing 12 of valve cell 14 is provided with the annular shoulder 18 of setting, and this shoulder 18 defines fluid outlet, and Purge gas is sent out from separator 2 by this fluid outlet. The annular shoulder 18 provided on valve cell housing 12 is substantially identical with the annular shoulder 6 of offer on rotor shell 4. Due to their similarity, entrance shoulder 6 and outlet shoulder 18 can receive the inlet/outlet tube stub with identical interface profile interchangeably. A this kind of tube stub 22 with 90 �� of elbows is shown in figure 3 with cross section. One end of tube stub 22 is provided with the circumferential collar 24 defining annular recess 26. Annular recess 26 has such right angle edge profile and diameter, and this edge, right angle profile and diameter allow it to receive housing annular shoulder 6,18 (this shoulder also has edge, right angle) (in the way of being adjacent).

Fig. 2 that the shoulder 6 of rotor shell 4 can refer to accompanying drawing with the joint of inlet pipe joint 28 finds out. It will be appreciated that the tube stub 28 shown in Fig. 2 has the different bent angle of the tube stub 22 from Fig. 3.

Inlet/outlet tube stub holds them at housing shoulder 6 with the use of annular packing ring 30, the corresponding housing 4,12 being fixed to them on 18, when the lug boss 34 that threaded fastener 32 is threaded with two engages threadably, packing ring 30 is pressed in downwards on the shoulder 24 of tube stub 22,28. Two lug bosses 34 are erect from relevant housing 4,12 and are positioned at the both sides of annular shoulder 6,18. O sealing member 36 is positioned at, catches and is compressed between recess 26 and housing shoulder 6,18, so that anti-fluid is undesirably leaked from the interface between inlet/outlet tube stub and corresponding housing (seeing Fig. 2 about inlet pipe joint).

With further reference to tube stub 22 shown in Fig. 3 and 2 respectively, 28,2nd end (distant place, one end being provided with interface profile) of tube stub is provided with tooth or sawtooth 38 on its outer surface, to grasp flexible pipe, this flexible pipe is positioned on tube stub the 2nd end in use.

The fluid flow path provided by two tube stubs 22,28 comprises the elbow with the basic interior turning 40 lacking radius separately. In prior art separator 2, angled tube stub uses injection-molded (for joint for plastic tube) and die casting (for aluminium tube joint) technology manufacture. As easily understood from Fig. 4 (which show the molded of tube stub 22), in order to allow respectively by the first and second arrows 46, removing the first and second inner molded part joint sections 42,44 on the direction of 48 instructions, moulded piece joint section 42,44 internally can not provide radius in turning 40.

To come referring specifically to Fig. 8 to describe the aforementioned inner component held by rotor shell 4 more in detail now.

First, top axle bearing unit 50 is fixed on the internal surface of rotor shell 4 in the direct downstream of fluid intake 8. Top axle bearing unit 50 comprises the cage bearing 52 caught between upper steel caps part 54 and the step parts 56 of plastic material. Bearing unit 50 is manufactured by step parts 56 molded around upper steel caps part 54, and wherein cage bearing 52 keeps between which fixingly. The layout of top axle bearing unit 50 clearly illustrates in fig. 8, but it is also shown in Fig. 2 and 9 in the environment of prior art separator 2.

Bearing holder component 56 has round-shaped and downward outstanding cylindrical wall 58 (low portion around cap member 54), and its cylindrical wall 60 abutting against rotor shell 4 in the separator 2 assembled laterally adjoins. Contribute to guaranteeing the correct lateral register of top axle bearing unit 50 relative to rotor shell 4 with cylindrical wall 60 is adjacent. 2nd cylindrical wall 62 of rotor shell 4 is radially positioned at the inner side of the first cylindrical wall 60, to guarantee the correct axial location of top axle bearing unit 50 relative to rotor shell 4. Top axle bearing unit 50 is fixed to rotor shell 4 by means of three threaded fastening piece (not shown)s. The layout of separator 2 makes the rotation of top axle bearing unit 50 overlap with the center axis 64 of rotor shell 4.

Three part circular grooves 66 (only show wherein two in Fig. 8) are provided in top axle bearing unit 50, to allow inlet fluid to flow through wherein (as by shown in arrow 68). Upper cap member 54 makes the inlet fluid from cage bearing 52 deflect, as will be understood by those skilled, but the downside of the topmost part of cap member 54 also makes upwards to be advanced through rotor spindle during use and enter lubricating oil mist deflection (in cage bearing 52) of top axle bearing unit 50.

Remaining internals of separator 2 and rotor shell 4 separate and assemble, and then assembly is positioned in housing 4 as a whole. Overall assembly is included in and keeps first group of fixing component relative to rotor shell 4 when using separator 2, and the 2nd group of component rotated around center axis 64 relative to rotor shell 4 (with valve cell housing 12) and first group of component when using separator 2.

First group of component comprises the supporting plate 70 of annular shape and is called the parts 72 of the dish type of housing plug-in unit. Housing plug-in unit 72 is combined and work and isolated the oil isolated and Purge gas before the oil isolated and Purge gas leave rotor shell 4 with supporting plate 70. Supporting plate 70 is formed from steel, and housing plug-in unit 72 is made up of plastic material. Supporting plate 70 and housing plug-in unit 72 are fixed to go up each other by means of three threaded fasteners 74 (showing only wherein in Fig. 1 of accompanying drawing), and the lug boss 76 that threaded fastener 74 is given prominence to downwards with the downside from housing plug-in unit 72 is threadedly engaged. This first group of component will be discussed subsequently in this specification more in detail.

2nd group of component form rotor assembly and comprise turning axle 78, upper rotor part dish 80, together formed separator disks 82 stacking 84 multiple independent separator disks 82, end plate 86, and the fan of combination and turbine unit 88. The component of the 2nd group according to so that the mode preventing them from relative to each other rotating is fixed to is gone up each other. But, the 2nd group of component is rotatably installed to first group of component by means of bottom bearing unit 90 (seeing Figure 10 especially).

To describe more in detail by the 2nd group of rotor assembly that component is formed now.

Turning axle 78 is made up of metallic substance, and has ring section, to provide the fluid flow path 92 extended longitudinally along its whole length. When using separator 2, this flowing-path 92 allows oil mist upwards transport through turning axle from turbine housing and be sent to top axle bearing unit 50, to lubricate the bearing of described unit 50. The flow restrictor element 93 of form that annular disc (has the cylindrical wall erect from its radially outer circumferential edge) be located at the described fluid flow path 92 of the upper end of turning axle 78 towards upper interior shoulder. Flow restrictor element 93 works and is reduced by the flowing-path area (thus providing nozzle) of turning axle 78 in the exit entering top axle bearing unit 50 from turning axle 78.

The outside of turning axle 78 is provided with some for receiving recess and the shoulder of back-up ring, and back-up ring contributes to the correct axial location being remained on by component on turning axle 78. A this kind of back-up ring 94 is in figure 6 clearly illustrated as providing towards upper shoulder, and packing ring 95 abuts against this back-up ring 94 and adjoins. Helical compression spring 96 adjoin packing ring 95 towards upper shoulder. Back-up ring 94 is positioned at peripheral recess wherein and has enough width (that is, the size on the axial direction due of recess), to allow back-up ring 94 to move vertically along turning axle 78 (in recess). This allows spring 96 that axial force is applied to bottom bearing unit 90.

Other recess is provided on the outside surface of turning axle 78, for being located by component and remain on described axle 78.

Each in upper rotor part dish 80, separator disks 82 and end plate 86 has frusto-conically shaped portion (defining fi-ustoconical surface 102), wherein multiple spoke parts radially extend inward into hub element from them, and this hub element is positioned at around turning axle 78 in use.

Although the spoke parts of upper rotor part dish 80 and separator disks 82 have unlimited space between which, to allow fluid to flow through them vertically along turning axle 78, but the spoke parts of end plate 86 are attached at their lower surface place and go up each other, so that anti-fluid along turning axle 78 or is upward through end plate 86 or is passed down through end plate 86 and flow vertically.

Upper rotor part dish 80 is substantially identical with the geometry of separator disks 82 with the geometry of the conical butt of end plate 86, to allow upper rotor part dish 80 and end plate 86 to be stacked with separator disks 82, wherein, upper rotor part dish 80 is positioned at the top place of separator disks stacking 84, and end plate 86 is positioned at the bottom place of separator disks stacking 84. In addition, although technician is it will be appreciated that separator disks 82 is relatively thin, so that the dish allowing larger amt is provided in relatively short stacking 84, but upper rotor part dish 80 and end plate 86 are much thicker than separator disks 82, to provide rigidity at the two ends place of dish stacking 84, and compression axial force is thus allowed evenly to be applied to the frusto-conically shaped portion of separator disks by upper dish 80 and end plate 86. Force of compression more specifically by be upwards pressed in end plate 86 hub 98 downside on helical compression spring 96 produce.

About compact disk stacking 84 between upper dish 80 and end plate 86, technician it is to be understood that the adjacent separator disks 82 in stacking 84 must keep being spaced apart from each other, to allow liquid flow to cross separator 2. This interval of separator disks 82 provides by means of the multiple ribs 100 (being called joint filling part) provided on the upper surface on the frusto-conically shaped portion of each separator disks 82. Each joint filling part 100 extends to the radially outer edge 106 on described surface from the inner radial edge 104 of described upper surface 102. Joint filling part 100 is erect from described upper surface 102 and is stretched out (standproudof), and in stacking the 84 of the separator disks 82 assembled, the downside of adjacent adjacent dish above. As the skilled person will appreciate, each separator disks 82 can be positioned on turning axle 78 relative in only six feasible Angle Position of turning axle 78, and the location of joint filling part 100 on described upper surface 102 makes the joint filling part of adjacent dish 82 must be aligned with each other when dish 82 is arranged in any one in these six positions. As a result, stacking 84 are passed through by means of the joint filling part 100 of alignment the interval of the force of compression being applied on dish stacking 84 by end plate 86 between adjacent separator disks 82 does not close.

In addition about the force of compression being applied to separator disks stacking 84, technician is it is to be understood that this power produces and is applied to by helical compression spring 96 on end plate hub 98. Due to the rigidity of end plate 86, force of compression is delivered to the frusto-conically shaped portion 108 of end plate 86 by multiple spokes 110 radially extended of end plate 86 from hub 98. Then force of compression is delivered to dish stacking 84 by frusto-conically shaped portion 108, and is upwards delivered to the frusto-conically shaped portion 112 of upper rotor part dish 80 by stacking 84 (by joint filling parts 100). Force of compression is delivered to the hub 114 of upper rotor part dish 80 by six spokes radially extended 116 from frusto-conically shaped portion 112. Force of compression can be delivered to hub 114 due to the rigidity of upper rotor part dish 80 from frusto-conically shaped portion 112. What force of compression was reacted by upper rotor part dish 80 prevents (seeing Fig. 6 especially) along turning axle 78 axial motion upwards by upper rotor part hub 114 being positioned in the peripheral recess 118 in the outside surface of turning axle 78. Frictional force between the outside surface of hub 114 and turning axle 78 prevents the relative rotation between them.

To specifically see from Fig. 6 and 8, the hub 114 of upper rotor part dish 80 extends to the point directly over end plate hub 98 along turning axle 78 downwards vertically. More particularly, hub 114 extends along the whole degree of depth of separator disks stacking 84, and the hub 120 thus making each separator disks 82 is separated (see Fig. 7) with turning axle 78. The hub 120 of each separator disks 82 has the hex shape limiting sexangle aperture, and turning axle 78 and upper rotor part hub 114 extend through this sexangle aperture. Separator hub 120 is relative to upper rotor part hub 114 (and therefore, relative to turning axle 78) rotary motion prevent by means of six keys 122, key 122 provides along the length of upper rotor part hub 114 vertically, and radially extends in six turnings in the sexangle aperture limited by separator hub 120. This position of key 122 prevents separator hub 120 relative to the side direction of turning axle 78 and rotary motion.

The separator hub 120 of each separator disks 82 is connected to the frusto-conically shaped portion 124 of each separator disks 82 by means of 12 spokes radially extended 126. Spoke 126 (and being in fact the residue part of the separator disks 82 being associated) is made up of relative thin and the plastic material that can flexibly bend. But, spoke 126 still can resist side direction and revolving force that they stand and not be out of shape. Technician is it is to be understood that the force of compression that whisker 96 produces passes through separator disks stacking 84 via joint filling part 100 instead of by separator plate convergence 126.

Technician is it will also be understood that the sexangle hub 120 of each separator disks 82 geometry relative with key 122 guarantees that each separator disks 82 can be positioned on turning axle 78 in only six Angle Position as mentioned above. But, though use in six Angle Position which, the position, pole of the joint filling part 100 of separator disks 82 or Angle Position are all identical, and therefore, there is not such possibility: when the joint filling part 100 of adjacent separator disks 82 is unjustified, separator disks stacking 84 is assembled on turning axle 78.

In order to clear, the dish that some figure in accompanying drawing shows the separator disks that there is the quantity reduced is stacking. Specifically simplify in an identical manner about prior art separator 2, Fig. 1,2,8,9 and 10.

As shown in Figure 5, second week is provided in the upper end of turning axle 78 to the position of recess 128 above the first recess 118. 2nd recess 128 receives the 2nd helical compression spring 130. The position of the 2nd recess makes, in the prior art separator 2 assembled, separate (see Fig. 6) between the lower end of the 2nd spring 130 and the hub 114 of upper rotor part dish 80, and prevent the lower end edge of the 2nd spring 130 the downward axial motion of turning axle 78 by what formed by the 2nd recess 128 towards upper shoulder. In addition, in the separator 2 assembled, the cage of cage bearing 52 is adjacent and compresses the 2nd spring 130 (wherein separate between the upper end of turning axle 78 and cap member 54 maintenance of top axle bearing unit 50 and see Fig. 8 especially) downwards. 2nd spring 130 by load applying to top axle bearing unit 50, and thus reduce top axle bearing unit 50 place vibration and the abrasion being associated.

The fan except combination in 2nd group of internals and all components except turbine unit 88 are shown as in Fig. 6 of accompanying drawing and assemble. When fan/turbine unit 88 is installed to the lower end of turning axle 78, the central circular aperture that the lower end of axle 78 is passed in each in the supporting plate 70 of first group of internals and housing plug-in unit 72 to provide and locate. Like this, the lower end of turning axle 78 also extends through the bottom bearing unit 90 (seeing Fig. 8 and 10 especially) in the center port being fixed to supporting plate 70.

The fan of combination and turbine unit 88 are fixed to the lower end of the turning axle 78 that the downside from supporting plate 70 is given prominence to downwards. Fan/turbine unit 88 is held in place on the lower end of turning axle 78 by means of the 2nd packing ring 133 towards upper surface of second gear circle 132 (remaining in the 3rd peripheral recess in axle 78) and adjacent second gear circle 132. The axial location of the fan/turbine unit 88 determined by second gear circle 132 on turning axle 88 causes the upper surface of unit 88 to be forced into and deflect packing ring 139 and adjoin, and deflection packing ring 139 is forced into again and adjoins with bottom bearing unit 90. In the separator 2 assembled, the bias voltage of adjacent first back-up ring 94 of the inner race of bottom bearing unit 90 and antagonism the first compression spring 96 upwards presses this back-up ring 94. Press inner race, deflection packing ring 139 and fan/turbine unit 88 so facing to second gear circle 132 to such an extent as to these elements are remained on the fixing position of rotation relative to turning axle 78.

The direction that the rotor assembly of separator 2 indicates along arrow 134 (see Fig. 1) by means of hydraulic impulse turbine rotates. Fan/turbine unit 88 comprises Pelton impeller 136, and this Pelton impeller 136 has the multiple wheel blades 138 being evenly spaced apart along its periphery. When using separator 2, the jet of oil is guided to the periphery of Pelton impeller 136 from the nozzle (not shown) in turbine housing 178. More particularly, jet guides along the tangent line of the circle through multiple wheel blade 138 so that this jet enters wheel blade (with its surface in alignment). Jet is along the described surface flow of the in-profile following wheel blade, and turns to by described profile afterwards, so that along other surface flow, and discharges from wheel blade afterwards. Result is that jet makes impeller 136 rotate.

The fan with multiple blade 140 also forms with impeller 136. Blade 140 is close to the downside of supporting plate 70 and is positioned on impeller 136. Multiple fan blade 140 is also positioned at the axial positions roughly the same with bottom bearing unit 90 along turning axle 78. Fan blade 140 extends radially outward near bottom bearing unit 90. It will be understood by persons of ordinary skill in the art that fan blade 140 rotates around center axis 64 when turbine wheel 136 rotates. Like this, fluid is dished out by fan blade 140 effectively from the region between impeller 136 and the downside of supporting plate 70, thus reduce the hydrodynamicpressure in the region of bottom bearing 90, and the oil isolated is pumped by bottom bearing unit downwards and is entered the turbine housing 178 below supporting plate 70 by the position above supporting plate 70.

For the ease of manufacturing, impeller 136 makes upper part 142 and low portion 144, and line 146 place shown in Fig. 8 of accompanying drawing is pressed onto and adjoins each other.

About first group of internals, supporting plate 70 is formed from steel and has round-shaped, and this is round-shaped has the substantially equal diameter of the diameter with rotor shell 4. Relative geometry so to such an extent as to allow supporting plate 70 be located at rotor shell 4 lower end towards under shoulder 148 on. By this way, the lower open end of rotor shell 4 is closed by supporting plate 70. Supporting plate 70 is also provided with central circular aperture, and this central circular aperture is concentric with rotor shell 4 in the separator 2 assembled. In other words, in the separator 2 assembled, the circular central aperture of supporting plate 70 is centered by the center axis 64 of rotor shell 4. In addition, as obvious especially in incited somebody to action from Fig. 1 of accompanying drawing, bottom bearing unit 90 is received in the center port of supporting plate 70. The radially portion part of bottom bearing unit 90 is fixed relative to supporting plate 70. The radial penetralia part of bottom bearing unit 90 is positioned near turning axle 78, but is not fixed to the upper.

As previously discussed, first group of internals also comprises the housing plug-in unit 72 being fixed to definitely on supporting plate 70. Housing plug-in unit 72 works separation purifying gas and the oil therefrom isolated, and is provided for the outlet 150 of Purge gas, and this outlet 150 is connected with the exit aperture 10 of rotor shell 4 (seeing Fig. 1 especially). Housing plug-in unit 72 is provided as the moulded piece of plastic material. But, when following description housing plug-in unit 72, will think that plug-in unit comprises four parts: outer cylindrical wall/skirt portions 152; Ditch part 154; Frusto-conically shaped portion 156; And limit the exit portion 158 of described plug-in unit outlet 150.

The cylindrical skirt portions 152 of housing plug-in unit 72 has the most external external diameter of the diameter substantially equaling the inner wall section with the adjacent rotor shell 4 of skirt portions 152. Peripheral recess 159 (see Figure 12) is provided in the outside surface of skirt portions 152, to receive O sealing member 160, this O sealing member 160 guarantees the sealing of the fluid between housing plug-in unit 72 chord transcapsidation body 4 in the separator 2 assembled.

The upside of the adjacent supporting plate 70 of the lower end of cylindrical skirt portions 152, and it is provided with the peripheral recess 162 (see Figure 12) for receiving the 2nd O sealing member 164. It is to be understood that the 2nd O sealing member 164 ensure that the sealing of the fluid between housing plug-in unit 72 and supporting plate 70.

The radially inner side and concentric the 2nd cylindrical wall arranged that are positioned at external skirt part 152 are connected to skirt portions 152 at its lower end, to form ditch part 154. Ditch part 154 forms the annular ditch (or groove) 166 that the inner cylinder wall along rotor shell 4 extends together with external skirt part 152. Ditch 166 has the cross section of U-shape, and during using separator 2, collect and dish out from separator disks 82 and (and the effect of the gas stream spiraled downwards, as described in more detail herein) advances downwards under gravity in the inside of rotor shell 4 the oil isolated drips. Ditch part 154 is provided with four discharge orifices 168 (seeing Figure 11 especially), collect in the oil in ditch 166 to flow by these four discharge orifices 168, so as use transmit during separator 2 upside that enters the downside by housing plug-in unit 72 and supporting plate 70 around region.

The Part III 156 of housing plug-in unit 72 has the shape of conical butt, and hangs ditch part 154. Frusto-conically shaped portion 156 is provided with central circular aperture, and this central circular aperture has the center axis that the center axis 64 with rotor shell 4 overlaps in the separator 2 assembled. Elongated recesses 170 (see Figure 11) is provided in the upper surface of frusto-conically shaped portion 156. This recess 170 defines the fluid path that the exit portion 158 with housing plug-in unit 72 for Purge gas links. This flowing-path provided by recess 170 starts from its upstream end, has the downward step 172 from the upper surface of frusto-conically shaped portion 156. The sidewall 174,176 of recess 170 outwards develops from the center of housing plug-in unit 72 along with fluid path and upwards increases height in downstream side. If the vertical view of housing plug-in unit 72 provided from Figure 11 is by apparent, recess 170 provides the straight fluid path of the length of the half with the diameter being substantially equal to housing plug-in unit 72.

There is provided the exit portion 158 of housing plug-in unit 72 with the form of the pipe of general cylindrical, this pipe extends across the aperture in external skirt part 152 and the ditch between ditch part 154 166.

Show the view of the separator 2 being fixed on turbine housing 178 in fig. 2. Separator 2 is fixed on turbine housing 178 by means of three threaded fastening pieces 180, and each in fastening piece 180 is through in three lug bosses integral with the lower end of rotor shell 4. The side cross-sectional view of Fig. 2 shows only a fastening piece 180 and lug boss 182. Those skilled in the art from Fig. 2 it will be appreciated that, supporting plate 70 (and, therefore all components of first group and the 2nd group) remain on the required position relative to rotor shell 4 by means of turbine housing 178, turbine housing 178 when rotor shell 4 and turbine housing 178 are fastened to and go up each other supporting plate 70 is depressed into towards under shoulder 148 adjoin. Supporting plate 70 is clamped between rotor shell 4 and turbine housing 178 by means of threaded fastening piece 180 substantially. Because threaded fastening piece 180 is tightened, and it is adjacent that supporting plate 70 and shoulder 148 are occurred, so, the 2nd helical compression spring 130 is compressed by top axle bearing unit 50.

When separator 2 operates, the jet of oil is directed on turbine wheel 136 by the nozzle (not shown) in turbine housing 178, to rotate turbine wheel in the direction indicated by the arrow 134, as previously described with respect to FIG 1. This rotary actuation rotor assembly of turbine wheel as a whole on the direction of arrow 134 center axis 64 around rotor shell 4 rotate. In other words, turning axle 78; Upper rotor part dish 80; Stacking the 84 of separator disks 82; End plate 86; And combination fan and turbine unit 88 (that is, being jointly called rotor assembly herein) rotate as the overall assembly in rotary shell 4 and relative to described housing 4 and supporting plate 70, housing plug-in unit 72 and turbine housing 178 together.

Release from engine crankshaft housing and need the gas processed by separator 2 to be introduced into separator 2 by being positioned at the fluid intake 8 at the top of rotor shell 4. As by shown in the arrow 68 in Fig. 8, inlet gas be parallel to center axis 64 and with the direction of center axis 64 conllinear on enter rotor shell 4, and flow through three in top axle bearing unit 50 groove 66 before flowing through six spokes 116 of upper rotor part dish 80. The rotary motion of six spokes also can cause the sidewise movement of the fluid between described spoke, because described fluid tangentially moves from the circular path of spoke 116, and effectively outwards dishes out towards the cylindrical wall of rotor shell 4. Substantially, cylindrical motion is imparted into gas by six spokes 116.

Inlet gas is downward through the spoke 116,126 of upper rotor part dish 80 and separator disks 82, and this gas laterally moves towards the cylindrical wall of rotor shell 4 via the space between adjacent separator disks 82, as shown in the arrow 184 in Fig. 8. The fluid being arranged in dish stacking 84 is given sidewise movement by joint filling part 100 together with the frictional force applied by separator disks 82, and this can cause described fluid outwards to move towards the cylindrical wall of rotor shell 4. This motion of the fluid caused by the rotation of dish stacking 84 is the main mechanism that fluid is drawn in separator 2 to adopt.

It will be understood by persons of ordinary skill in the art that oil drips 186 and tends to pool together and form bigger dripping at the periphery place of dish stacking 84. With regard to this point, act on the capillary force (Small Distance due between adjacent separator disks 82) that less oil drips and tend to prevent droplet from dishing out from dish stacking 84. But, along with more oil moves through separator disks, the less periphery place that drops in pools together, and forms bigger the dripping with the quality (and " centrifugal " power being associated) being enough to overcome capillary force. Spontaneously throw afterwards on the cylindrical wall of rotor shell 4. Once receive by described cylindrical wall, oil drip 186 just tend to gravity and by the effect of the gas stream of separator 2 under advance to downwards in annular ditch 166. Separate between the most external circumferential edge of separator stacking 84 is fully inside relative to the cylindrical wall of rotor shell 4, do not advance to downwards in described ditch 166 by the obstruction of separator disks 82 to allow oil to drip. O sealing member 160 guarantees that oil drip enters ditch 166, instead of between housing plug-in unit 72 and rotor shell 4 (its possible consequence (as being easier to understand with reference to Fig. 1) with the cleaning gas polluting the outlet 150 flowing through housing plug-in unit 72).

The oil collected in ditch 166 is dripped 186 and is therefrom emitted by four discharge orifices 168. This discharge effect is assisted by the FPG in rotor shell 4 and turbine housing 178. More particularly, it will be understood by persons of ordinary skill in the art that the rotary motion due to rotor assembly, the hydrodynamicpressure in rotor shell 4 is bigger in the peripheral edge place of separator disks stacking 84 is than the region between the downside of housing plug-in unit 72 and the upside of supporting plate 70. As a result, tend to there is the downward Purge gas stream by discharge orifice 168. This liquid flow tends to promote the oil isolated to drip along annular ditch 166, and promotes it to pass downwardly through discharge orifice 168 and arrive on supporting plate 70 below. This gaseous fluid stream is indicated (seeing Fig. 8 especially) by arrow 188. Gaseous fluid stream radially-inwardly moves through the upper surface of supporting plate 70 towards the central round orifice opening's edge in housing plug-in unit 72. This stream crossing supporting plate 70 tends to promote the oil isolated to drip and crosses supporting plate 70 towards bottom bearing unit 90, and described oil drips through this bottom bearing unit 90. The fan blade 140 of the fan of combination and the rotation of turbine unit 88 tends to reduce the static pressure in turbine housing 178 in the region of bottom bearing unit 90. This contributes to extracting oil again and drips by bottom bearing unit 90. But, pump oil to drip the major measure that adopted by bottom bearing unit 90 packing ring 139 provides by deflecting, in use, this deflection packing ring 139 rotates relative to supporting plate 70 together with turbine unit, and from rotor shell 4 pump oil, even if being also like this when the pressure in the pressure ratio rotor shell in turbine housing is bigger. Then described outwards thrown in turbine housing 178 by fan blade 140, and they can return engine crankshaft housing from this turbine housing 178. Meanwhile, the gaseous fluid flowing through supporting plate 70 is drawn upwardly the center port sent by package case 72, and leaves rotor shell 4 by means of housing plug-in unit outlet 150 and rotor shell outlet 10.

With reference to accompanying drawing it will also be understood that except flowing through discharge orifice 168, some in Purge gas flow to outlet 150,10 (not flowing in ditch 166) via the alternative route between end plate 86 and the upper part of ditch part 154. This alternative route is indicated by arrow 190.

It will be appreciated that there is on bearing unit useful lubricant effect by the oil stream of bottom bearing unit 90. Top axle bearing unit 50 is similarly by naturally appearing in turbine housing 178 and be upwards sent to the oily mist lubrication of top axle bearing unit 50 by the longitudinal flow path 92 of extend through turning axle 78.

Although prior art separator 2 has proved effectively to run, but there is the problem that some are associated with this separator, they have utilized the improvement existed in the separator of amendment described hereinafter and have been solved. These problems can think three wide in range classifications.

First, causing the pressure-losses by the fluid path of separator 2, this pressure-losses can affect the stream ability of separator unfavorablely and therefore affect the size of the engine that can use together with this separator. Can therefore be considered to relevant with the pressure-losses in fluid flow path to the first kind problem that prior art ALFDEX separator is associated.

2nd, the layout of prior art separator makes Purge gas under certain conditions to become to be polluted before leaving separator. Therefore, it will be recognized that the 2nd class problem being associated to prior art separator and undesirable oil pollution of Purge gas are relevant.

3rd, some manufacturing technology being associated with prior art separator and constitutional features can cause assembling difficulty and/or reliability problem. Therefore, it will be recognized that the 3rd class problem being associated to prior art separator and manufacture and the reliability of separator are relevant.

Now all kinds of by what discuss in these classifications more in detail.

About by the fluid flow path of this separator 2, there are some positions, the higher pressure-losses can be experienced in these positions. First, the interior turning 40 of the elbow in inlet/outlet tube stub 22,28 too sharply to such an extent as to produces fluid from the separation the internal surface of tube stub in the region in the direct downstream at described interior turning 40. This separation itself is recirculated fluid stream (or whirlpool), and it can cause again energy/pressure-losses. But, as above about accompanying drawing Fig. 4 described by, the radius providing big on interior turning when utilizing injection-molded or die casting technology manufactures inlet/outlet tube stub has problem. As a result, prior art separator 2 when fluid enters rotor shell 4 and leaves and experiences the pressure-losses in valve cell housing 12 two kinds of situations at tube stub place.

Contriver has realized that, six spokes 116 of upper rotor part dish 80 are the other reasons of undesirable pressure-losses. Specifically, seeing especially from Fig. 5 and 6, spoke 116 has square-section separately, and the axial stream of the releasing gas entered is presented sharp-pointed upper trailing edge (see Fig. 5) at upper rotor part dish 80 by them when the side of arrow 134 rotates up. The sharp-pointed trailing edge 192 of the shape having been found that spoke 116, particularly each spoke, can cause fluid separation and undesirable pressure-losses.

Contriver also finds that the specific structure of housing plug-in unit 72 can cause undesirable pressure-losses. Specifically, during using separator 2, Purge gas to be such as downward through the frusto-conically shaped portion 156 of housing plug-in unit 72 by the rotary motion around center axis 64 shown in the arrow 194 in Figure 12. This Purge gas stream flows through frusto-conically shaped portion 156 after flowing downward along the internal surface of cylindrical sidewall of rotor shell 4 with the pattern spiraled. It is to be understood that therefore, Purge gas is from the region (instead of entering described region a specific position) between the end plate 86 entering a little frusto-conically shaped portion 156 and top of the circumferential periphery along housing plug-in unit 72. Therefore the flowing-path striding across frusto-conically shaped portion 156 has eddy flow pattern, and this pattern can cause undesirable pressure/power loss. , it is provided that the step 172 of the recess 170 in frusto-conically shaped portion 156 and wall 174,176 produce other territory, flow separation zone, and the undesirable pressure-losses being associated in addition.

About the two class problem relevant with oil pollution, contriver has realized that some features of the prior art separator 2 of the possibility that the air that can improve purification is polluted under certain conditions. As described above, first, the stream passing downwardly through the Purge gas of rotor shell 4 is partly entered ditch 166 and tends to be extracted out the oil isolated by discharge orifice 168 and drips. If the flow rate of the air of purification is enough not high for the specified level of processed oil pollution, the oil then collected in ditch 166 drips the ditch part 154 that can climb up housing plug-in unit 72, and then flows on the frusto-conically shaped portion 156 of housing plug-in unit 72 (see Figure 10). Once oil drips enters region between frusto-conically shaped portion 156 and end plate 86, oil drips and just unavoidably leaves separator 2 and removing pollutant gas. Oil drips that to climb from ditch 166 may be the result of the low flow rate allowing undesirably a large amount of oil to collect in the Purge gas ditch 166. The Purge gas that existence upwards circulates in ditch 166 also can be tended to upwards to extract oil and drip, and is drawn on the frusto-conically shaped portion 156 of housing plug-in unit 72. But, the notable feature allowing oil to drip the prior art separator 2 rising from ditch 166 of climbing is pipe-type outlet part 158 (see Figure 12). Although discharge orifice 168 is positioned on the both sides of exit portion 158, but will understand from Figure 12 of accompanying drawing, oil in ditch 166 drips the circular path deferring to the bottom along ditch 166, if and oil droplet does not flow through discharge orifice 168 in the direct upstream of exit portion 158, then oil drips the path will tended to defer to arrow 196 (see Figure 12) and indicate, and upwards flows through exit portion 158 and flow on the frusto-conically shaped portion 156 of housing plug-in unit 72.

The oil that the present inventor also finds to isolate drips and can upwards flow through the center port of housing plug-in unit 72 and flow on frusto-conically shaped portion 156, and thus removing pollutant gas. This undesirable stream of the oil isolated tend to by discharge orifice 168 and upwards by the flow rate of the Purge gas of the center port of housing plug-in unit 72 (as indicated in the arrow 188 in Fig. 8) relatively high time occur. It will be appreciated by those skilled in the art that, the high flow-rate of Purge gas causes the oil isolated to drip upwards being carried the center port by housing plug-in unit 72, instead of allows the oil isolated to drip the effect by gravity and deflection packing ring 139 and pump by bottom bearing unit 90 downwards.

The inventors also found that too much oil can be introduced into separator disks stacking 84 through the longitudinal flow path 92 of turning axle 78, as by indicated by the arrow 198 as shown in Fig. 2. During normal operating condition, the mist that impeller described in the jet impulse of the oil of driving turbine wheel 136 and the thin oil of generation drip. This mist of oil is upwards sent to top axle bearing unit 50, and then transports through the stacking of separator disks 82 downwards. Generally, the amount of the oil transmitted by this way is enough to lubrication top axle bearing unit 50, is also easily isolated from the gas stream entered by separator disks stacking 84 subsequently simultaneously. But, in some cases, the amount of the oil transporting through turning axle 78 greatly to causing oil spill go out ditch 166 or otherwise flow on the frusto-conically shaped portion 156 of housing plug-in unit 72, and may flow into purified gas outlet 10 subsequently. This can such as occur when separator 2 tilts and the lower end of turning axle 78 is directly exposed to the oil storage that remains in turbine housing 178 surperficial.

About the three class problem relevant with reliability with the difficulty manufactured, contriver has realized that the following problem about prior art separator 2.

First, about manufacture separator 2, contriver finds to use threaded fastening piece 32 to be fixed to by inlet/outlet tube stub on rotor shell 4 and valve cell housing 12 may be consuming time, and needs O sealing member 36.

Manufacturing the time length that spends of prior art separator 2 also is subject to needing top axle bearing unit 50 with bottom bearing unit 90 so that the impact that can align vertically around the mode of same axis 64 rotation of two bearing units 50,90. Specifically, rotor shell 4 is made up of plastic material by means of injection molding process, and the present inventor finds that rotor shell 4 during cooling exists the tendency of warpage. Due to this warpage, the position of the first cylindrical wall 60 (it laterally locates top axle bearing unit 50) of rotor shell 4 is tended to be positioned at different lateral position relative to the lower end of rotor shell 4 compared with expection. As a result, supporting plate 70 (and therefore bottom bearing unit 90) can become laterally to offset from its desired location. This problem alleviates by allowing rotor shell 4 to cool on the relatively long time period after injection molding process. This, section decreased the warpage of rotor shell 4 long cooling time, but was the increase in manufacturing time.

The other problem being associated from the assembling of separator 2 relates between different components, such as interface between rotor shell 4 and valve cell housing 12. More particularly, if separator 2 will be provided with the valve cell 14 (or in fact just do not have valve cell) different from originally desired valve cell, then must also use different rotor housing 4, to guarantee and the correct joint of new valve cell (or when will be other tubing system when not using valve cell). This can uncomfortable local raising cost and built-up time. In addition, asymmetric (the causing for the moulded piece profile engaged with valve cell housing 12 by what provide on described housing 4) of rotor shell 4 tends to cause described housing 4 warpage during manufacturing, such as, and this tends to cause the problem unjustified relevant problem of component (with) during assembling.

The present inventor it is also recognised that on housing plug-in unit 72 provide big O sealing member 160 possible breakdown. More particularly, it is necessary to O sealing member carrys out the major diameter face seal against two couplings, and a surface provides on housing plug-in unit 72, and a surface provides on the cylindrical wall of rotor shell 4. Both rotor shell 4 and housing plug-in unit 72 all have bigger manufacture error, and this can cause O sealing member 160 can not correctly seal two components. In addition, because two components use injection moulding technology to manufacture by plastic material, each moulded piece moulded piece of rotor shell 4 (and particularly) stands warpage after injection molding process. This can cause O sealing member 160 can not correctly seal two components 4,72 in addition. If it is to be understood that O sealing member 160 fault, then the oil isolated is by the region 200 that leaks between the skirt portions 152 of the external cylindrical of housing plug-in unit 72 and the cylindrical wall of rotor shell 4. Leak into the oil in this region 200 and will finally enter the outlet 150 of housing plug-in unit 72 and removing pollutant gas. If O sealing member 160 fault on the position of outlet 150, then the oil isolated will tend to leak through O sealing member 160 and directly enter outlet 150. Warping effect (by increasing the cooling time after injection molding process) is reduced, or when (ii) replaces leaker after product test, sealing problem can increase manufacturing time when (i) takes measures.

In addition, the moulded piece burr being arranged in the recess 159 receiving O sealing member 160 can cause O sealing member fault.

The present inventor also recognizes and the reliability problem for being associated with the layout of fixing angular orientation location separator disks 82 relative to turning axle 78. As above Fig. 7 about accompanying drawing sets forth, prevent separator disks 82 from rotating relative to turning axle 78 by means of six keys (being fixed on turning axle 78) engaged with the sexangle aperture in hub 120 or each separator disks 82. But, the vibration (such as engine luggine) that separator is typically exposed to during use can cause the abrasion of the interface between the sexangle aperture in key 122 and hub 120. This abrasion can cause the significant relative rotary motion between separator disks 82 and turning axle 78. In fact, the present inventor has been found that adjacent separator disks 82 can relative to each other rotate the degree reaching joint filling part 100 and becoming unjustified, thus allows the space between adjacent separator disks 82 to close. If this occurs in a large number of dish 82, then the degree of depth of separator disks stacking 84 can reduce to and make the hub 98 of end plate 86 abut against, by compression spring 96, the degree that upper rotor part hub 114 compresses. It is to be understood that then force of compression no longer can be delivered to separator disks stacking 84 by end plate 86, and result, independent separator disks 82 freely can move up and down (and rotating relative to turning axle 78) along turning axle 78 vertically. This motion is very undesirable, and can reduce the separation performance of separator disks stacking 84 significantly.

The other reliability problem that contriver recognizes relates between (i) turning axle 78 and top/bottom bearing unit 50,90; And

(ii) fretting wear of interface between turning axle 78 and the first compression spring 96 is corroded. Such as, it will be understood by persons of ordinary skill in the art that fretting wear is corroded to occur when may have relative movement (owing to comparing loose cooperation between described component) between components. To compare, loose cooperation extends through top and bottom bearing unit 50,90 and the first compression spring 96 to turning axle 78. This allows, by the first and second compression springs 96,130, axis preload is applied to top and bottom bearing unit 50,90. Specifically, it is to be understood that bottom bearing unit 90 is applied axial force by the first compression spring 96 from accompanying drawing, and top axle bearing unit 130 is applied axial force by the 2nd compression spring 130. The loose fit of turning axle 78 and top/bottom bearing unit 50,90 and the first compression spring 96 allows the vibratory drive between these components. This can cause again the fretting wear on described component to corrode. Relative movement between component also can allow hard particle to enter between described component, and this can accelerate abrasion further and cause reliability problem.

The separator of the improvement being used for overcoming the above problems of the present inventor's exploitation is described now with reference to Figure 13 to 41.

Those skilled in the art the separator of improvement understanding the present inventor's exploitation from accompanying drawing immediately is had many with prior art separator 2 the similar or identical component of function performed by them and their general structure aspect. Such component describes hereinafter by with the use of with the identical reference label used about prior art separator 2 above in the context of the separator improved. Such as, with reference to Figure 13 of accompanying drawing, technician is it is to be understood that the separator 2 ' of improvement shown in this Fig comprises the rotor shell 4 ' of general cylindrical, and it corresponds to the rotor shell 4 of prior art separator 2 and performs similar function. Pass through accompanying drawing, structure and function difference between the component of such correspondence will be apparent for technical personnel, but when difference is obvious when solving the problem about prior art separator 2 or the technique manufacturing prior art separator 2 and provide relative to prior art separator 2 or manufacture the improvement of technique of prior art separator 2, substantially these differences will be discussed in detail.

It will be understood by persons of ordinary skill in the art that the rotor shell 4 ' that the separator 2 ' of improvement comprises general cylindrical shape is separated some fuel-displaced internals with working from the gas of the releasing being directed to described rotor shell 4 '. As mentioned below, some in internals are positioned at rotor shell 4 ', and other internals is (such as, the fan of combination and turbine unit) it is positioned at the outside of rotor shell 4 ', such as, however, it is positioned in another housing (turbine housing).

The upper end of cylindrical housing 4 ' is provided with the annular shoulder 6 ' of setting, which defines the fluid intake 8 ' of the separator 2 ' leading to improvement. Release from crankshaft shell and need the gas therefrom removing oil to enter separator 2 ' via fluid intake 8 '.

Aperture 10 ' in the cylindrical wall 201 of rotor shell 4 ' provides outlet, and by this outlet, Purge gas is sent to the independent housing 12 ' (seeing Figure 13 especially, 14 and 15) of valve cell 14 ' from the inside of rotor shell 4 '. Exit aperture 10 ' extend through and therefore by cylindrical lug boss 202 around, this cylindrical lug boss 202 extends from the outside surface of rotor shell 4 ' itself.

The valve that valve cell 14 ' comprises the flowing for controlling the Purge gas from separator 2 ' is arranged. Due to the above description to prior art separator 2, the details of the operation of valve cell 14 ' can not describe herein. But, technician by be familiar with for improvement of separator valve cell function operation.

As from Figure 13 and 14 by apparent, and particularly from Figure 15 by apparent, the internals of valve cell 14 ' is centered around in the housing 12 ' being separated with rotor shell 4 ' overallly. More particularly, valve cell housing 12 ' comprises first part 203 and second section 205, and they are fitted to each other and form the enclosed space of sealing, and the internals of valve cell 14 ' is arranged within this space. With reference to Figure 15, it will be seen that the upper end of the first part 203 of valve cell housing 12 ' is provided with lug boss 207, and traditional threaded fastener 16 ' extends through this lug boss 207, to be threadedly engaged with the other lug boss 209 on rotor shell 4 '.

From Figure 15 also it will be seen that, the lower end of the first part 203 of valve cell housing 12 ' is provided with the part 211 of general cylindrical, this part 211 extends away from valve cell housing 12 ', and extends to the inside of rotor shell 4 ' via the exit aperture 10 ' in rotor shell 4 '. O sealing member 213 is positioned on the outside surface of cylindrical part 211, and adjoins against shoulder (limit on said surface), this shoulder in the separator 2 ' assembled towards the inside of rotor shell 4 '. When promoting described part 211 during assembling by exit aperture 10 ', shoulder thus prevents O sealing member 213 from moving along cylindrical the undesirable of part 211, and O sealing member 213 engages with described aperture 10 '. More particularly, engage the face seal of O sealing member 213 and the interior cylindrical of the lug boss 202 around exit aperture 10 '.

When O sealing member 213 towards cylindrical part 211 root end (namely, one end of adjacent cylindrical part is divided with the remainder of valve cell housing) when providing, the 2nd O sealing member 215 is provided on the outside surface of free end (away from root end) of cylindrical part 211. With identical when the first O sealing member 213,2nd O sealing member 215 abuts against towards on the shoulder of the inside of rotor shell 4 ', to prevent undesirable motion of the 2nd O sealing member 215 when described sealing member is pressed into final utilization position in the separator 2 ' assembled. More particularly, from Figure 15 it is to be understood that in the separator 2 ' assembled, the 2nd O sealing member 215 engages with the outlet 150 ' of housing plug-in unit 72 ' with sealing.

Technician is it will also be understood that the first O sealing member 213 prevents Purge gas and/or oil from dropping in leakage between rotor shell 4 ' and valve cell housing 12 ', and prevents them from thus undesirably leaking into environment from separator 2 '. Technician is also it will be further understood that the 2nd O sealing member 215 prevents oil droplet from leaking into the outlet 150 ' of housing plug-in unit 72 ' and thus polluting the Purge gas leaving rotor shell 4 ' via cylindrical part 211 in addition. Cylindrical part 211 and the first and second O sealing members 213, the little external diameter (compared with the major diameter O sealing member 160 of prior art separator 2) of 215 allows to use relatively little manufacture error, this error guarantees the less trouble about two O sealing members 213,215. With regard to this point, it is understood that such as, the warpage degree of the cylindrical part 211 of relatively little diameter will be less than the rotor shell 4 of the relative major diameter of prior art separator 2.

The lower end of the first part 203 of valve cell housing 12 ' is provided with the 2nd lug boss 207 on the side being positioned at cylindrical part 211. Identical with the situation of the first lug boss 207 provided on the upper end of first part 203, the 2nd lug boss 207 on the lower end of first part 203 receives traditional threaded fastener 16 ', to be threadedly engaged (seeing Figure 18 about described 2nd lug boss 207,209) with the 2nd lug boss 209 provided on the lower end of rotor shell 4 '.

Owing to valve cell housing 12 ' is the housing being separated with rotor shell 4 ', and geometrically independent with it (except mating and above and below lug boss 207 of cylindrical part 211 and exit aperture 10 ', outside the joint of 209 pairs), the rotor shell 4 ' of the separator 2 ' of improvement has the overall shape of the more closely overall shape of similar right cylinder compared with the rotor shell 4 of prior art separator 2. With regard to this point, it is noted that prior art rotor housing 4 comprises the relative complex of the part (and being not only the matched interfaces about it) forming prior art valve cell housing 12 that works and huge moulded piece profile on side. But, with reference to Figure 15, it will be seen that the rotor shell 4 ' of the separator 2 ' of improvement does not comprise aforementioned complexity and huge moulded piece profile.

Owing to rotor shell 4 ' has the shape close with the shape of right cylinder, housing 4 ' can use injection moulding technology to become with the amount of warpage manufacture of minimizing compared with the housing 4 of prior art separator 2 during process for cooling. This allows more easily to make top and bottom bearing unit 50 ', 90 ' align vertically. In addition, to understand, as long as the rotor shell 4 ' shown in accompanying drawing can connect with the alternative valve cell of the valve cell 14 ' shown in accompanying drawing-alternative valve cell has the cylindrical part 211 that the exit aperture 10 ' being applicable to rotor shell 4 ' is mated, and it is applicable to the lug boss 207 that the lug boss 209 with rotor shell 4 ' mates (valve cell housing 12 ' when) as shown in Figure 15. Such as, if alternative valve cell has with the cylindrical part identical with lug boss 207 with the cylindrical part 211 shown in Figure 15 and two lug bosses and with the housing of the relative location identical with shown in Figure 15, then alternative housing can be much bigger compared with the valve cell housing 12 ' shown in Figure 15, and hold the inner valve from the valve cell 14 ' shown in accompanying drawing and arrange that completely different inner valve is arranged. This allows the modular structure of separator 2 ', and wherein parts have the versatility of increase between the different layouts of separator.

With reference to Figure 15, it will be seen that the housing 12 ' of valve cell 14 ' is provided with the setting annular shoulder 18 ' defining fluid outlet, and by this fluid outlet, Purge gas spreads out of from separator 2 '. At the upper annular shoulder 18 ' provided of valve cell housing 12 ' with substantially identical at the upper annular shoulder 6 ' provided of rotor shell 4 '. Due to their similarity, entrance shoulder 6 and outlet shoulder 18 can receive the inlet/outlet tube stub with identical interface profile interchangeably. Figure 13 shows the identical inlet/outlet tube stub 22 ' with 90 �� of elbows. Show inlet pipe joint 22 ' with cross section to mate with the shoulder 6 ' of rotor shell 4 ', and it is shown as in fig. 17 in addition and is separated with described shoulder 6 '.

As being clear that from the side cross-sectional view of Figure 16, the bending surface combination of the internal surface of tube stub 22 ' 216 and shoulder 6 ' limits the fluid flow path having 90 �� of elbows and having radius significantly outside on turning and interior turning. As a result, compared with the liquid flow at the sharp-pointed turning 40 arranged through prior art, the trend that fluid is separated from the interior turning of elbow reduces more. Then also reduce the pressure-losses.

Now with reference to rotor shell shoulder 6 ' (shoulder 18 ' of itself and valve cell housing 12 ' is identical), the interface between inlet/outlet tube stub 22 ' and corresponding housing shoulder 6 ', 18 ' is described more in detail.

As shown in figure 16 and 17, providing the setting shoulder 6 ' of rotor shell 4 ' as annular relief, this annular relief has the general cylindrical wall 217 centered by the longitudinal axis to overlap with the center axis 64 ' of rotor shell 4 '. The free end of cylindrical wall 217 (distant place of residue part at rotor shell 4 ') is provided with the circumferential antelabium 219 on the bending surface 221 that formation extends inward in the aperture formed by shoulder 6 '. In cross section (see Figure 16), bending surface 221 has part circular shape and the arc 223 of about 110 �� of extend through. Part circular surface 221 is oriented so that the described radial direction of surperficial 221 225 is parallel to longitudinal axis of cylindrical wall 217 and extends. In specific layout shown in figure 16, part circular surface 221 swept arcs 223 terminate in aforementioned radial 225 places. From the side cross-sectional view of Figure 16 it will also be understood that the surface 227 of the external cylindrical of shoulder 6 ' overlaps with described radial 225, and crossing with part circular surface 221 and form the upper limb 229 of shoulder 6 '.

In addition, referring specifically to Figure 16, it will be appreciated that, the profile that tube stub 22 ' is provided with shoulder 6 ' mates so that part circular surface 221 combination of the internal surface 216 of tube stub 22 ' and shoulder 6 ' provides does not have convex ridge, shoulder, discontinuous and/or produce the smooth-flat-surface of any further feature of the pressure-losses towards upstream/downstream. More particularly, the geometry of tube stub 22 ' makes the transition part on the part circular surface 221 from the internal surface 216 of tube stub 22 ' to shoulder 6 ' that obstruction or other pressure-losses can not be utilized to produce feature and provides the liquid flow passing through the surface (by the either direction of tube stub 22 ') combined. Given shoulder 6 ' is symmetrical, and no matter tube stub 22 ' is relative to how angle orientation or the pole of housing 4 ' locate, and all keeping is this kind of situation.

Seamlessly transitting between the internal surface of tube stub 22 ' and part circular surface 221 realizes in the following way in the layout of the separator 2 ' improved: the internal surface of tube stub 22 ' being configured so that, inner tube joint surface 216 is all oriented and is in the tangential of part circular surface 221 at each some place of inner tube joint surface 216 with part circular surface 221 intersections. Therefore, about the interior turning of the elbow being combined to form by tube stub/shoulder, the preceding edge 229 place's intersection at shoulder 6 ' of inner tube joint surface 216 and part circular surface 221, and at this plotted point place, it is oriented orthogonal to aforementioned radial 225 (that is, tangent with part circular surface 221). When a people circumferentially advances around shoulder 6 ' to the outer corner of the elbow being combined to form by tube stub/shoulder, inner tube joint surface 216 radially moves inward through part circular surface 221 gradually with the surperficial point residing for 221 intersections of the part circular of shoulder 6 '. Figure 16 can seeing, inner tube joint surface 216 is in edge 231 place of inner tube joint surface 216 and part circular surface 221 intersections.

In practice, due to the restriction of injection moulding technology and the cost constraint that is associated with high level error, the transition part between part circular surface 221 and inner tube joint surface 216 not necessarily will all not have discontinuous or other pressure-losses to produce feature on the whole. Especially, can there is gap between the edge 231 of tube stub 22 ' and the part circular surface 221 of shoulder 6 '. This gap in practice by utilize die casting technology manufacture by steel (or other metallic substance) in tube stub 22 ' and part circular surface 221 or both and reduce.

Tube stub 22 ' is provided with the shoulder of the general cylindrical of cylindrical wall 233 form in addition, and it has the internal diameter of the cylindrical wall 217 with the housing shoulder 6 ' internal diameter equal with external diameter and external diameter. When tube stub 22 ' is positioned on described shoulder 6 ', the cylindrical wall 233 of tube stub 22 ' mates with one heart with the cylindrical wall 217 of housing shoulder 6 '. Bending wall 235 is radially outward toward the upper limb of tube stub cylindrical wall 233 from aforementioned inner tube joint surface edge 231. In cross section, the shape of bending wall 235 is part circular, and it is concentric and be adjacent to be configured to the surface of the part circular with housing shoulder 6 ' 221.

Two fins 237 are positioned at the outside of tube stub 22 ' and extend from bending wall 235, to provide extra rigidity for described wall 235 and prevent or reduce tube stub 22 ' bending between described wall 235 and the residue part (see Figure 13) of tube stub 22 '.

As, in prior art separator 2, the tube stub 22 ' of the separator 2 ' of improvement uses traditional injection-molded or die casting technology manufacture, result defines sharp-pointed interior turning 239 (see Figure 34). Can think that this turning 239 is similar to the interior turning 40 of prior art tube stub 22. It is to be understood, however, that the existence on the part circular surface 221 of housing shoulder 6 ' combines the tube stub 22 ' improved ensure that the internal portion of the flowing-path elbow to housing 4 ' place provides radius. As mentioned above, this is unrelated relative to the angular orientation of housing 4 ' with tube stub 22 '. Thus reduced from the separation of the fluid of the internal surface of elbow or avoided, and the pressure-losses in this part of flowing-path is reduced similarly or avoids.

Finally, about the geometry of tube stub 22 ', the 2nd end (being provided with the distant place of one end of housing interface profile) of described tube stub is provided with tooth or sawtooth 38 ' on its outer surface, to grasp the flexible pipe being positioned on tube stub the 2nd end in use.

Again emphasize that rotary shell shoulder 6 ' is identical with the shoulder 18 ' on valve cell housing 12 ', and outlet pipe connection 22 ' by with above about rotor shell shoulder 6 ' described identical in the way of be connected to the 2nd housing shoulder 18 '.

From above it is to be understood that tube stub 22 ' can be positioned at shoulder 6 ' as shown in Figure 16 and with this shoulder 6 ' adjacent while do not rotate with not being obstructed. Therefore, tube stub 22 ' is rotatable to be welded on shoulder 6 ', tube stub 22 ' is fixed to housing definitely with required angular orientation. Those skilled in the art are not it will be appreciated that the method for fixed tube joint 22 ' needs to use threaded fastening piece as in prior art separator 2. It will also be understood that this spin welding technology allows tube stub 22 ' to fix with any angular orientation relative to housing 4 ', and whole circumference (or closed loop) sealing is provided and does not need O sealing member. Specifically, described melt surface is caused by the heat produced in housing 4 ' (that is, shoulder 6 ') and the frictional force acted on during the relative rotation of the abutment surface of tube stub 22 ' between the surfaces. Then stop the rotation and described surface cure, thus it is bonded to each other.

Although above-mentioned spin welding is the effective method being attached on the material of housing 4 ' by the material of tube stub 22 '; But such as, also can use other method in conjunction with described material (tackiness agent combines, ultra-sonic welded or Vibration Welding).

Referring specifically to Figure 34, aforementioned inner component will be described more in detail now.

First, top axle bearing unit 50 ' is fixed to the internal surface of rotor shell 4 ' in the direct downstream of fluid intake 8 '. Top axle bearing unit 50 ' is identical with the top axle bearing unit 50 of prior art separator 2, and therefore comprises the cage bearing 52 ' caught between upper steel caps part 54 ' and the step parts 56 ' of plastic material. Top axle bearing unit 50 ' (and also having bottom bearing unit 90 ') comprises roller bearing (as in prior art separator 2), but can alternatively comprise sliding surface bearing or friction bearing.

More particularly, bearing holder component 56 ' has round-shaped and downward outstanding cylindrical wall 58 ' (low portion around cap member 54 '), and it is positioned at the cylindrical wall 60 ' (but not laterally near it) of rotor shell 4 ' in the separator 2 ' assembled. Cylindrical wall 60 ' extends downwards from the upper inside surface of rotor shell 4 '. Circular convex ridge 238 also extends downwards from the upper inside surface of rotor shell 4 ', and is positioned at the radially inner side of the first cylindrical wall 60 '. The cylindrical wall 60 ' of rotor shell 4 ', circular convex ridge 238 and aforementioned shoulder 6 ' are located concentrically with respect to one another, and centered by the center axis 64 ' of rotor shell 4 '.

As will hereinafter be described in more detail (with reference to Figure 37 to 41), top axle bearing unit 50 ' is fixed to the upper inside surface of rotor shell 4 ' by means of spin welding technology. Specifically, step parts 56 ' are welded on convex ridge 238. And use threaded fastening piece that top axle bearing unit 50 ' is fixed to rotor shell 4 ' like that not as in prior art separator 2. This layout makes the rotation of top axle bearing unit 50 ' overlap with the center axis 64 ' of rotor shell 4 '.

Top axle bearing unit 50 ' provides three part circular grooves 66 ' (only show wherein two in Figure 34), to allow inlet fluid to flow through wherein (as by shown in arrow 68 '). The deflection of upper cap member 54 ' is from the inlet fluid of cage bearing 52 '. As, in prior art separator 2, the downside of the topmost part of cap member 54 ' also makes lubricating oil mist deflection (in cage bearing 52 ') being upwards advanced through rotor spindle during use.

Remaining internals of separator 2 ' assembles independent of rotor shell 4 ', and then assembly is partly positioned in housing 4 ' removedly as a whole. As about prior art separator 2, it will be recognized that keep first group of fixing component and the 2nd group of component rotated around center axis 64 ' relative to rotor shell 4 ' (and valve cell housing 12 ') and first group of component in use when this entirety assembly is included in use relative to rotor shell 4 '.

First group of component comprises the supporting plate 70 ' of annular shape and the housing parts/plug-in unit 72 ' of dish type. As in prior art separator 2, housing plug-in unit 72 ' and supporting plate 70 ' combine to work each other and leave, at the oil isolated and Purge gas, the oil that the front isolation of rotor shell 4 ' isolates from Purge gas. Supporting plate 70 ' is formed from steel, and housing plug-in unit 72 ' is made up of plastic material. Supporting plate 70 ' and housing plug-in unit 72 ' are fixed to by means of three threaded fasteners 74 ' (see Figure 29) to be gone up each other, and the lug boss 76 ' that these three threaded fasteners 74 ' and the downside from housing plug-in unit 72 ' are given prominence to downwards is threadedly engaged. The opening end of the closed rotor shell 4 ' of supporting plate 70 ', to provide the closed interior space of housing 4 ', the some components in the 2nd group of component are positioned at wherein. With regard to this, can think that rotor shell 4 ' is the first housing parts limiting internal space, such as, this internal space is used for receiving for separating of material (oil and gas) and the component that the material isolated is directed to different outlets from described internal space. Can think that supporting plate 70 ' is the 2nd housing parts limiting described internal space with the first housing parts.

First group of component will be discussed in this specification hereinafter more in detail.

2nd group of component forms rotor assembly, and comprise turning axle 78 ', upper rotor part dish 80 ', together formed separator disks 82 ' stacking 84 ' multiple independent separator disks 82 ', fan disk 240, end piece/plate 86 ', the fan of splash plate dish 242 and combination and turbine unit 88 '. Turning axle 78 ' is made up of metallic substance, and the residue part of the aforementioned components of the 2nd group is made up of plastic material and is utilized injection moulding technology manufacture. The aforementioned components of the 2nd group goes up each other to be used for preventing from or at least limit being fixed in the way of they relative to each other rotate. 2nd group of component additionally provides helical compression spring (metallic substance), as described in more detail below. 2nd group of component is rotatably installed on first group of component by means of bottom bearing unit 90 ', and is rotatably installed on rotor shell 4 ' by means of top axle bearing unit 50 ' in the separator 2 ' assembled.

The rotor assembly of the 2nd group of component formation will be described more in detail now.

Turning axle 78 ' has ring section, to provide the fluid flow path 92 ' extended longitudinally along its whole length. When using separator 2 ', this flowing-path 92 ' allows oil mist upwards transmitted by turning axle from turbine housing and be delivered to top axle bearing unit 50 ', to lubricate the bearing of described unit 50 '. The outside of turning axle 78 ' is provided with some recesses and shoulder, and they contribute to remaining on component on turning axle 78 ' correct axial location.

Each in upper rotor part dish 80 ', separator disks 82 ', fan disk 240 and end plate 86 ' has the frusto-conically shaped portion (limiting upper and lower fi-ustoconical surface) being connected to be positioned on the center hub element of turning axle 78 ' surrounding in use.

When upper rotor part dish 80 ', separator disks 82 ' and end plate 86 ', frusto-conically shaped portion utilizes multiple spoke parts radially extended internally from it to be connected to the center hub element being associated. These spoke parts have the space opened between which, to allow fluid to pass axially through them and flow along turning axle 78 '.

When fan disk 240, frusto-conically shaped portion 290 is connected to the center hub element 292 being associated by means of the 2nd frusto-conically shaped portion 294. 2nd frusto-conically shaped portion 294 is continuous print, intercepts to be provided by fluid, and thus anti-fluid along turning axle 78 ' or is upward through fan disk 240 or is passed down through fan disk 240 and flows vertically.

The shape of the conical butt of the 2nd frusto-conically shaped portion 294 has the angle bigger than the angle of other frusto-conically shaped portion of the separator 2 ' improved. In other words, with the frusto-conically shaped portion of the situation of the first frusto-conically shaped portion 290 of fan disk 240 or upper rotor part dish 80 ', separator disks 82 ' and end plate 86 ' (and in fact, the isolating roof parts 268 of the shape of the conical butt of housing plug-in unit 72 ') situation (they all have identical angle) compare, the phase offside of the 2nd frusto-conically shaped portion 294 is dispersed quickly/is assembled. Center hub element 292 is the cylindrical wall erect from the 2nd frusto-conically shaped portion 294 (seeing Figure 26 and 33 especially). The groove 296 (showing only wherein in Figure 26) extended longitudinally is provided by the whole thickness of the cylindrical wall of fan boss element 292, for the key 254 that reception radially extends from turning axle 78 '. By this way, prevent fan disk 240 relative to the rotation of turning axle 78 '.

The downside of the first frusto-conically shaped portion 290 of fan disk 240 is provided with multiple joint filling part parts 298 that the center axis around fan disk 240 separates between equidistantly. Each joint filling part parts 298 are provided as the straight convex ridge outstanding from the downside of the first frusto-conically shaped portion 290 downwards, and extend to the radially edge, portion of the first frusto-conically shaped portion 290 in radial directions from the radial penetralia edge of the first frusto-conically shaped portion 290. In the separator 2 assembled, joint filling part parts 298 adjoin the upper surface of the frusto-conically shaped portion of end plate 86 ', and the interval thus guaranteed between fan disk 240 and end plate 86 ', fluid can pass this interval (as indicated by the arrow 188 ' in Figure 34). In use separator 2 ' period, the fluid rotated to be between fan disk 240 and end plate 86 ' of joint filling part parts 298 gives rotary motion. As a result, described fluid outwards moves towards the cylindrical wall 201 of rotor shell 4 '. Oil drips (and/or, in fact other liquid entrained by gas stream or particulate pollutant) dishes out effectively facing to the cylindrical wall 201 of rotary shell 4 ', and to dirty (or falling) on supporting plate 70 '. The gaseous fluid discharged from the space between fan disk 240 and end plate 86 ' or also flow to supporting plate 70 ' downwards or directly leave rotor shell 4 ', sets forth as hereafter general will be more detailed.

About end plate 86 ', the radial penetralia circular edge of frusto-conically shaped portion 108 ' is connected to center hub element 98 ' (see Figure 18) by means of multiple spoke parts 110 '. But, the wall 300 of cylinder form also extends downwards from the described radial penetralia edge of frusto-conically shaped portion 108 '. In the separator 2 ' assembled, cylindrical wall 300 is centered by center axis 64 ', and extends fully downwards along turning axle 78 ', so that the center port that extend through provides in package case 72 '. Although described wall 300 has the shape of general cylindrical, but the internal surface 302 of described wall 300 defines the shape of conical butt so that the internal diameter of cylindrical wall 300 reduces in an upward direction in the separator 2 ' assembled. The cylindrical outside surface of wall 300 has the substantially identical diameter of the center port with housing plug-in unit 72 ', and in the separator 2 ' assembled, is positioned in described aperture, makes to have between wall 300 and package case 72 ' minimum spacing. This closely cooperates, and while allowing the relative rotation between end plate 86 ' and package case 72 ', contributes to minimizing can flow between described wall 300 and the center port of package case 72 ' so that the amount of the oil isolated of removing pollutant gas. In addition, work and resist the oil upwards flowed and drip in the space being sent between fan disk 240 and end plate 86 ' in the Inner frustoconical shape surface 302 of described wall 300. It will be understood by persons of ordinary skill in the art that the oil of the fi-ustoconical surface of contact wall 300 drips and will stand rotary motion, and the shape of the conical butt due to described surface, stand the power of effect downwards.

Splash plate dish 242 comprises the annular disc 304 of plane, this dish 304 is connected to center hub element 308 by means of six the spoke parts 306 radially extended internally from it, and this center hub element 308 is positioned at around turning axle 78 ' (seeing Figure 28 especially) in the separator 2 ' assembled. The diameter of the center port limited by the annular disc 304 of plane equals the internal diameter of the lower end of the cylindrical wall 300 of end plate 86 ' substantially. Therefore junction surface place between splash plate dish 242 and end plate 86 ' there is not the significant pressure-losses and produce feature in the liquid flow entering the region fan disk 240 and end plate 86 ' through splash plate dish 242. It will be appreciated that, annular disc 304 provides flange parts, these flange parts extend from the lower end edge radial direction of described cylindrical wall 300, and any spacing worked in use between the outside surface covering described cylindrical wall 300 and the part limiting the center port that described wall 300 extends through of housing plug-in unit 72 '. By this way, the annular disc 304 of plane reduce the oil isolated drip spatter or otherwise move up from supporting plate 70 ' and through the center port of package case 72 ' so that the possibility of removing pollutant gas.

To understand in addition, described region between fan disk 240 and end plate 86 ' defines flowing-path 616, outlet 620 (edge limited by the radial outer periphery of fan disk 240 and end plate 86 ') is arrived from entrance 618 (limiting by splash plate dish 242), as shown in Figure 34 for fluid passes.

The hub element 308 of splash plate dish 242 provides as right cylinder, and its upper end is closed by the wall of the plane of the longitudinal axis (and, in the separator 2 ' assembled, be perpendicular to center axis 64 ') being arranged to be perpendicular to described right cylinder. The internal diameter of described right cylinder is bigger than the external diameter of turning axle 78 ', and the wall of plane is provided with center port, and described axle 78 ' passes this center port in the separator 2 ' assembled. This layout makes, in the separator 2 ' assembled, the right cylinder of turning axle 78 ' and hub element 308 limits annular space between which, this annular space receives helical compression spring 96 ', adjoin splash plate dish 242 is depressed into end plate 86 ', end plate 86 ' then abut against upper rotor part dish 80 ' pressure fan disk 240 and dish stacking 84 '.

It will be understood by persons of ordinary skill in the art that splash plate dish 242 and end plate 86 ' separate manufacture, so that the cylindrical wall 300 allowing end plate 86 ' is located through the center port of package case 72 '. If splash plate dish 242 and end plate 86 ' are one, then this will be impossible, because the external diameter of annular disc 304 is bigger than the diameter of the center port in housing plug-in unit 72 '.

As mentioned above, the geometry of the conical butt of upper rotor part dish 80 ', fan disk 240 (about its first frusto-conically shaped portion) and end plate 86 ' is substantially identical with the geometry of separator disks 82 '. This allows upper rotor part dish 80 ', fan disk 240 and end plate 86 ' stacking together with separator disks 82 ', and wherein, upper rotor part dish 80 ' is positioned at the top place of separator disks stacking 84 ', and end plate 86 ' is positioned at the bottom place of separator disks stacking 84 '. Fan disk 240 is arranged between the separator disks 82 ' of foot (that is, locating bottom it) of end plate 86 ' and separator disks stacking 84 '.

In addition, although technician will be it will be appreciated that separator disks 82 ' will be thinner, to allow the dish providing larger amt in relatively short stacking 84 ', but upper rotor part dish 80 ' and end plate 86 ' are much thicker than separator disks 82 ', to provide rigidity at the two ends place of dish stacking 84 ', and thus allow, by means of upper dish 80 ' and end plate 86 ', compression axial force evenly is applied to the frusto-conically shaped portion of separator disks 82 '. It is to be understood that force of compression is produced by described helical compression spring 96 ', helical compression spring 96 ' is upwards pressed on the downside of hub 308 of splash plate dish 242. Then, the anti-hub 308 spattering boot disk 242 is upwards pressed on the downside of adjacent hub 98 ' of end plate 86 '.

About the compression of the dish stacking 84 ' between upper dish 80 ' and end plate 86 ', technician it will be appreciated that, as prior art separator 2, the adjacent separator disks 82 ' in stacking 84 ' must keep being spaced apart from each other, to allow fluid to flow through the separator 2 ' of improvement. This interval of separator disks 82 ' is provided in the separator 2 ' improved by means of multiple intervals part 246. Each interval part 246 is on the upper surface 102 ' of the frusto-conically shaped portion 124 ' being positioned at each separator disks 82 ' and from its outstanding point (see Figure 20).

The separator disks 82 ' of the bottom in stacking 84 ' can selection of land also and between fan disk 240 separate, to allow fluid to flow between which. If needing this kind of interval, then use suitable interval part. Desirable ground, the upper surface of first frusto-conically shaped portion (the 2nd frusto-conically shaped portion below its frusto-conically shaped portion being positioned at dish stacking 84 ' and by means of fan disk 240 is connected to fan hub) of fan disk 240 is provided with interval part 246 in the way of identical with the frusto-conically shaped portion of each separator disks 82 '.

Such as, each in described interval part 246 has round-shaped, but can use other shape (can use elliptical shape). Any alternative shape for interval part 246 preferably has bending edge, so that the fluid pressure loss in reducing the fluid flowing through interval part.

First group of interval part 246 is arranged in the circle concentric and adjacent with the inside circular edge 104 ' of described upper surface 102 '. Each interval part 246 in this first group be positioned at inside circular edge 104 ', near the part of the frusto-conically shaped portion of the spoke link dish 82 ' of its mid-game 82 '. 2nd group of interval part 246 is arranged in circle that is concentric with the outer circular edge 106 ' of described upper surface 102 ' and that be adjacent. 3rd group of interval part 246 is arranged in the inner circular edge 104 ' of the frusto-conically shaped portion with dish 82 ' and outer circular edge 106 ' is concentric and in the circle of about centre between which.

As hereinafter will more detailed with setting forth, each separator disks 82 ' (and, in fact, fan disk 240) can be positioned on turning axle 78 ' relative in turning axle 78 ' only three feasible Angle Position, and the location of interval part 246 on described upper surface 102 ' makes the interval part 246 of the dish 82 ' adjacent when dish 82 ' is arranged in any one in these three positions must be aligned with each other. In other words, when vertically separator disks 82 ' is shifted onto turning axle 78 ' upper and push it to each other adjacent to form aforementioned stacking 84 ' time, necessary: each interval part 246 of (i) specific dish 82 ' is located in stacking 84 ' to be positioned at directly over the interval part 246 of adjacent dish 82 ' of described specific dish 82 ' lower section, and each interval part 246 of (ii) specific dish 82 ' is located in stacking 84 ' to be positioned at immediately below the interval part 246 of adjacent dish 82 ' of described specific dish 82 ' top. As a result, the interval of the force of compression being applied to dish stacking 84 ' by end plate 86 ' between adjacent separator disks 82 does not close, interval part 246 by means of alignment passes through stacking 84 '. This guarantees that fluid keeps to flow between separator disks 82 '.

It will be appreciated that with reference to the accompanying drawings, interval part 246 has little radial dimension and little circumferential size for the size of the separator disks being associated (diameter). This allow fluid in the way of relatively not hindering by interval part circumferentially direction flow through described dish upper surface 102 ', and radially flow through described surperficial 102 '. This guarantees the minimise loss of pressure in the liquid flow between adjacent dish 82 '.

Figure 21 and 23 of accompanying drawing shows upper rotor part dish 80 ' isolate with other component of turning axle 78 ' with separator 2 '. The hub 114 ' of upper rotor part dish 80 ' is molded on the outside surface of turning axle 78 ', and is thus attached on described axle 78 '. This combination prevents the relative rotation between hub 114 ' and turning axle 78 '.

The hub 114 ' of upper rotor part dish 80 ' upwards extends vertically along turning axle 78 ', and terminates in the upper end of described axle 78 '. The upper part (the 2nd helical compression spring 130 ' is positioned at around it) of turning axle 78 ' is thus provided with the coating (lining) of plastic material (preferred thermoplastic). This coating protection spring 130 ', and particularly protect axle 78 ' to corrode from fretting wear. First group of the alternative of the first embodiment 2 ' and the 2nd group of internals show in Figure 19. Except the plastic coating that the upper end part of wherein turning axle 78 ' is adjacent with the 2nd whisker 130 ', alternative separator is identical with the first embodiment.

The hub 114 ' of upper rotor part dish 80 ' also extends downwards vertically along turning axle 78 ', and terminates the some place directly over bottom bearing unit 90 '. Bottom bearing unit 90 ' thus contacts the metal end of turning axle 78 ' in the separator 2 ' assembled. More particularly, hub 114 ' extends along the whole degree of depth of separator disks stacking 84 ', and thus makes the hub 120 ' of each separator disks 82 ' be separated with turning axle 78 '. It will also be understood that hub 114 ' is also the coating (lining) that turning axle 78 ' provides plastic material (preferred thermoplastic) in the region of the first helical compression spring 96 '. In addition, this coating protection spring 96 ', and particularly axle 78 ', corrode from fretting wear.

The frusto-conically shaped portion 112 ' of upper rotor part dish 80 ' is connected to hub 114 ' by the spoke parts 116 ' that 12 radially extend. Each spoke parts 116 ' have the cross section of rectangular shape, and on it, the radial penetralia circular edge 312 of described frusto-conically shaped portion 112 ' is adjoined in (little) side 310. Each spoke parts 116 ' extend downwards vertically from described edge 312. This layout makes when upper rotor part dish 80 ' is when using separator 2 ' period to rotate, and each spoke parts 116 ' play the effect of fan blade, and give motion on adjacent fluid. As will be understood by those skilled, the motion being given to fluid by each spoke parts 116 ' causes fluid tangentially to flow from the circular path of spoke parts 116 ', and frusto-conically shaped portion 112 ' lower section and effectively outwards dish out towards the cylindrical wall of rotor shell 4 ' through dish stacking 84 '. Spoke parts 116 ' can cause upper rotating disk 80 ' to rotate as the function of fan blade, thus by fluid intake 8 ' (as indicated by the arrow 68 ' in Figure 34) and by the space 600 between spoke parts 116 ' by gas suction rotor shell 4 ', thus described space 600 represents the entrance of rotor assembly.

The fluid entering rotor shell 4 ' passes three part circular grooves 66 ' in top axle bearing unit 50 '. In the separator 2 ' assembled, the spoke parts 116 ' of upper rotor part dish 80 ' are positioned at the underface of three part circular grooves 66 '. Referring specifically to Figure 34 of accompanying drawing, it will be seen that, the radial dimension that the radial dimension of part circular groove 66 ' is less than spoke parts 116 ' is (namely, length), as a result, a very big part for the fluid entered only impacts the length of the underface being positioned at part circular groove 66 ' of spoke parts 116 ' at first. This length of each spoke element 116 ' is provided with the bending fluid stator 314 that side (or leading edge) 310 from it upwards extends. The object of each stator 314 reduces or eliminates to be separated, from spoke parts 116 ', the pressure-losses being associated with inlet fluid. This realizes in the following way: be provided in the rotor shell 4 ' with stator by the basic axial stream of inlet fluid, this stator has the cross section of aerodynamic shape, and is oriented the string of the angle of attack (maybe can not cause another angle of attack that fluid is separated from stator 314) about the liquid flow entered with basic zero degree.

Show the sectional view of the length through the spoke parts 116 ' being provided with stator 314 in fig. 22. Work and guide the fluid of the leading edge 310 close to spoke element 116 ' to align with spoke element 116 ' in the surface of stator 314. The string 316 being associated with the leading edge 318 of stator 314 is oriented the angle of attack about the fluid flowing through described stator 314 with basic zero degree. This fluid is represented by arrow 320 relative to the direction of stator 314, and as indicated by Figure 22, it will be appreciated that for be (i) inlet fluid flow (amount) (Q/A, wherein, Q is the volume fluid flow rate by entrance; And A is the section area of inlet flow paths) axial velocity, and the tangential velocity of (ii) stator 314 (wherein, �� is upper rotor part dish is circular frequency to �� r; And r is stator apart from the radial distance of rotation center) function. Because liquid flow depends on the radial position r along stator 314 relative to the direction 320 of stator 314, string 316 can be oriented to along with the angle that radial position changes. In other words, fluid stator 314 can be provided with torsion, to guarantee stator 314 and the liquid flow entered correctly aliging in all radial positions along stator 314. More particularly, acute angle 322 between string 316 and vertical reference line 324 (parallel with the center axis 64 ' in the separator 2 ' assembled) can increase towards the radial position of most external radial position gradually along spoke parts 116 ' from penetralia.

Technician it will be appreciated that, using the separator 2 ' period improved, the air entered is downward through three part circular grooves 66 ' vertically, and impacts and be arranged on described groove 66 ' lower section short distance and the stator 314 that rotates at circular path around center axis 64 '. Because the string 316 of the leading edge 318 of each stator 314 is oriented the angle of attack relative to the liquid flow entered with basic zero degree, both the low-tension side 324 that described fluid flows through stator 314 and high-tension side 326, and directed and flow on the axial direction due relative to spoke parts 116 ', and can not be separated from stator 314 or the spoke being associated parts 116 '. The pressure-losses produced by the fluid flowing through upper rotor part dish 80 ' is thus avoided or minimumization.

The other result of reduction of the pressure-losses that stator 314 provides is that the quantity of spoke parts 116 ' can increase (compared with prior art separator 2) and can desirably affect by the liquid flow of separator 2 ' flow rate as a whole. The spoke parts 116 ' increasing quantity allow bigger force of compression to transmit between the frusto-conically shaped portion 112 ' and hub 114 ' of upper rotor part dish 80 '. The spoke parts 116 ' increasing quantity also can improve the balance of upper rotor part dish 80 '.

It will be noted that the schematic diagram in the cross section of spoke parts 116 ' that Figure 22 presents stator 314 and is associated, and not necessarily represent particularly preferred geometry or in fact it is particularly preferred speed of rotation and fluid flow rate.

With reference to Figure 21, it will be seen that cylindrical rim 328, it is provided as concentric with the radial penetralia edge 312 of frusto-conically shaped portion 112 ' and erects from this edge 311. In the separator 2 ' assembled, rim 328 is positioned at radial outside relative to the outstanding cylindrical wall 58 ' of top axle bearing unit 50 ' downwards. But rim 328 is located close to described cylindrical wall 58 ' place, (or limiting significantly) fluid leak (seeing Figure 34 especially) between them to prevent.

Three keys 254 radially extend from the hub 114 ' of upper rotor part dish 80 ', as will be the most easily seen from Figure 23 of accompanying drawing. These three keys 254 separate between equidistantly around the central longitudinal axis of upper rotor part dish 80 ', and the following point along hub 114 ' is extended to vertically along hub 114 ' (and therefore along turning axle 78 ') from the downside 330 of spoke parts 116 ': the separator 2 ' assembled, this is approximately positioned at centre along the center hub element 292 of fan disk 240.

Each key 254 has root portion 350 and tip portion 352. Root portion 350 links with the residue part of hub 114 '. Tip portion 352 is adjoined root portion 350 and is provided free end to key 254. The root portion 350 of each key 254 wider than tip portion 352 (that is, there is bigger circumferential size). Due to the different in width of root portion 350 and tip portion 352, the junction surface between root portion 350 and tip portion 352 is on the both sides of each key 254 provides step 354. Referring specifically to Figure 23, it will be seen that the width of the root portion 350 of each key 254 increases from the lower end of each key 254 to the upper end of each key 254. In addition, the width of each root portion 350 almost equals the width (that is, circumferential size) of in 12 spokes 116 ' of upper rotor part dish 80 '. The tip portion 352 of each key 254 is also circumferentially alignd with spoke parts 116 ' and is adjoined with it.

The hub 120 ' of each separator disks 82 ' has aperture 252, and turning axle 78 ' and upper rotor part hub 114 ' are extended (seeing Figure 23 especially, 24 and 25) by this aperture. Preventing separator hub 120 ' relative to the rotary motion of upper rotor part hub 114 ' (and therefore relative to turning axle 78 ') by means of three keys 254, these three keys 254 provide and radially extend to the cloudy coupling profile of the correspondence that the aperture 252 of separator hub 120 ' limits vertically along the length of upper rotor part hub 114 '. This position of key 254 prevents separator hub 120 ' relative to the side direction of turning axle 78 ' and rotary motion. More particularly, the surface 358 (this surface 358 also radially extends substantially) of the correspondence of surface 356 (this surface 356 radially extends substantially) the adjacent described coupling profile of the tip portion 352 of each key 254, to prevent the relative rotation of separator disks 82 ' and upper rotor part hub 114 ' (and turning axle 78 '). To understand, in use, abutment surface 356,358 are being generally perpendicular on the direction of described in each surperficial 356,358 to be pressed against go up each other, and due to this reason, exist very little or there is no described surperficial 356, the sliding relative movement of 358, and described surperficial 356,358 very little or the division (factional) abrasion (it can cause the increase between separator disks 82 ' and upper rotor part hub 114 ' or undesirable relative rotation) that is not associated.

The separator hub 120 ' of each separator disks 82 ' is connected to the frusto-conically shaped portion 124 ' of each separator disks 82 ' by means of the spoke parts 126 ' that 12 radially extend. As in the separator 2 ' of prior art, spoke 126 ' (and the residue part of the separator disks 82 ' being associated) by relative thin and the plastic material that can flexibly bend make. Again, as in the separator 2 ' of prior art, spoke 126 ' can be resisted side direction and revolving force that they stand and can not be out of shape, and the force of compression produced by whisker 96 ' via interval part 246 but not passes through separator disks stacking 84 ' by separator plate convergence 126.

It will also be understood that as previously discussed, the key 252 of each separator disks 82 ' ensure that with the relative geometry in aperture 252 each separator disks 82 ' can be positioned on turning axle 78 ' in only three Angle Position to technician. By means of the location of interval part 246 relative to aperture 252, the pole of the interval part 246 of separator disks 82 ' or location, angle keep identical relative to turning axle 78 ', no matter and use in three Angle Position which, and therefore, do not exist the interval part 246 of adjacent separator disks 82 ' unjustified time the separator disks stacking 84 ' possibility that is assembled on turning axle 78 '. However, each separator disks 82 ' be provided with can with the mark of the label alignment of other dish 82 ' in dish stacking 84 '. By this way, all dishes 82 ' in stacking 84 ' will have identical Angle Position relative to turning axle 78 '. Mark provides as being positioned on hub between two spokes 126 ' and extend radially outward short-range rib 256.

In order to clear, Figure 13 of accompanying drawing, 15,19,20,27,33,34 show the separator disks that dish stacking 84 ' exists quantity minimizing.

The annular recess 258 (see Figure 21) concentric with turning axle 78 ' is provided on the upper surface of upper rotor part hub 211 '. Annular recess 258 receives the 2nd helical compression spring 130 ' and prevents this spring 130 ' along the downward axial motion of turning axle 78 '. In addition, in the separator 2 ' assembled, the cage of cage bearing 52 ' is adjacent and compresses the 2nd spring 130 ' (wherein separate between the upper end maintenance of turning axle 78 ' and the cap member 54 ' of top axle bearing unit 50 ' and see Figure 34 especially) downwards.

In the separator 2 ' period that assembling improves, the 2nd group of internals is all connected to each other mutually except the fan of combination and turbine unit 88 '. Upper rotor part hub 114 ' (and residue part of upper rotor part dish 80 ') and turning axle 78 ' are molded together in in-situ injection. Stacking the 84 ' of separator disks 82 ' then axially slides along turning axle 78 ' from its lower end edge, so that the downside being positioned to the frusto-conically shaped portion 112 ' with upper rotor part dish 80 ' adjoins.

Be installed to the lower end of turning axle 78 at fan/turbine unit 88 before, the central circular aperture provided in each in the supporting plate 70 that the lower end of axle 78 is positioned through in first group of internals and housing plug-in unit 72. Like this, the lower end of turning axle 78 also extends through bottom bearing unit 90, and this bottom bearing unit 90 is fixed to the center port (seeing Fig. 8 and 10 especially) of supporting plate 70.

In addition about the force of compression being applied to separator disks stacking 84 ', technician is it is to be understood that this power is produced by helical compression spring 96 '. In use separator 2 ' period, compression spring 96 ' rotates together with turning axle 78 ', and the inner radial seat ring of the lower end of compression spring 96 ' and bottom bearing unit 90 ' adjoins, so that facing to its extrusion, and described power is upwards delivered to splash plate hub 308. Then force of compression is delivered to end plate hub 98 ' from splash plate hub 308. Splash plate 242 is interrupted due to the frictional force (it will be understood to the effect of force of compression) between splash plate hub 308 and end plate hub 98 ' relative to the rotation of end plate 86 '.

Due to the rigidity of end plate 86 ', force of compression is delivered to the frusto-conically shaped portion 108 ' of end plate 86 ' from hub 98 ' by described multiple spoke parts 110 ' radially extended. Then force of compression is delivered to the joint filling part parts 298 of fan disk 240 by frusto-conically shaped portion 108 ', and then upwards passes through stacking 84 ' (via interval part 246) from the frusto-conically shaped portion 290 of fan disk 240 and be sent to the frusto-conically shaped portion 112 ' of upper rotor part dish 80 '. Force of compression is delivered to the hub 114 ' of upper rotor part dish 80 ' from frusto-conically shaped portion 112 ' via 12 spokes radially extended 116 '. Force of compression can be delivered to hub 114 ' due to the rigidity of upper rotor part dish 80 ' from frusto-conically shaped portion 112 '. Upper rotor part dish 80 ' react on force of compression and upwards along turning axle 78 ' axial motion by with on turning axle 78 ' towards under the position of the adjacent upper rotor part hub 114 ' of shoulder 250 and prevent. Upper rotor part dish 80 ' prevents along the axial motion of turning axle 78 ' by with the position towards the upper adjacent upper rotor part hub 114 ' of annular shoulder 248 on turning axle 78 ' downwards.

The adjacent dish 82 ' of dish stacking 84 ' selection of land can be fixed to and go up each other definitely. Namely, it is ensured that dish interval part 246 keeps alignment, this will tend to the rigidity of raising dish stacking 84 ' and guarantee that the relatively rotation place of adjacent dish 84 ' can not change (to transmit force of compression and space between adjacent dish 82 ' can not close). Such as, dish 82 ' is fixed on by welding (ultra-sonic welded) and goes up each other.

In prior art separator 2 ', be installed to the lower end of turning axle 78 ' at fan/turbine unit 88 ' before, the lower end of axle 78 ' is positioned to the central circular aperture by providing in each in the supporting plate 70 ' of first group of internals and housing plug-in unit 72 '. The lower end of turning axle 78 ' also extends through the bottom bearing unit 90 ' (seeing Figure 29 and 30 especially) of the center port being fixed to supporting plate 70 '.

The fan of combination and turbine unit 88 ' are fixed to the lower end of the turning axle 78 ' given prominence to the downside from supporting plate 70 ' downwards. Fan/turbine unit 88 ' is by means of back-up ring 132 ' (remaining in the peripheral recess in the lower end of turning axle 78 ') and is positioned at around the lower end of turning axle 78 ' and being held in place on the lower end of turning axle 78 ' towards the helical compression spring 360 on upper surface of adjacent back-up ring 132 '.

Back-up ring 132 ' and compression spring 360 are positioned at the fan of combination and the cavity of turbine unit 88 '. Compression spring 360 upwards compresses in described cavity, fan/turbine unit 88 to be upwards biased into the inner radial raceway contacts with bottom bearing unit 90 '. This layout is the most apparent from Figure 30 of accompanying drawing. With reference to this figure, it is understood that be provided in described unit 88 ' towards upper deflector surface 139 ', and be positioned at the radially inner side of the fan blade 140 ' of described unit 88 '. Deflector surface 139 ' performs the function identical with the deflection packing ring 139 in prior art separator 2, but provides integratedly with fan/turbine unit 88 ', instead of the adjoining members of separation. The inner radial part of deflector surface 139 ' is upwards pressed onto the inner race with bottom bearing unit 90 ' and is adjoined, and this inner race is upwards pressed against on supporting plate 70 ' again. The radially outer bearing seat ring of deflector surface 139 ' and bottom bearing unit 90 ' is spaced apart from each other vertically, to allow the oil isolated be downward through bottom bearing unit 90 ' and flow radially outwardly through described axially spaced-apart and enter turbine housing.

The rotor assembly of separator 2 rotates up (see Figure 29 and 30) in the side indicated by arrow 134 ' by means of hydraulic impulse turbine. As, in prior art separator 2 ', fan/turbine unit 88 ' comprises the Pelton impeller 136 ' with the multiple wheel blades 138 ' being evenly spaced apart along its periphery. When using separator 2 ', the jet of oil guides the periphery to Pelton impeller 136 ' from the nozzle (not shown) in turbine housing. More particularly, jet is along the tangential guiding of the circle through multiple wheel blade 138 ' so that jet enters the wheel blade with its surface in alignment. Jet is along the described surface flow of the in-profile deferring to wheel blade, and rotates by described profile afterwards, with along other surface flow, and discharges from wheel blade afterwards. Result is that jet makes impeller 136 ' rotate.

The fan with multiple blade 140 ' also forms with impeller 136 '. Blade 140 ' is close to the downside of supporting plate 70 ' and is positioned on impeller 136 '. The plurality of fan blade 140 ' is also on the axial location roughly the same with bottom bearing unit 90 ' with deflector surface 139 ' along turning axle 78 '. Fan blade 140 ' extends radially outward near bottom bearing unit 90 '. It will be understood by persons of ordinary skill in the art that, when turbine wheel 136 ' rotates, fan blade 140 ' rotates around center axis 64 '. Like this, fluid is dished out by fan blade 140 ' effectively from the region between impeller 136 ' and the downside of supporting plate 70 ', thus reduce the hydrodynamicpressure in the region of bottom bearing unit 90 ', and contribute to pumping by bottom bearing unit and the turbine housing pumping to supporting plate 70 ' lower section the oil isolated downwards from the position of supporting plate 70 ' top.

For the ease of manufacturing, impeller 136 ' makes upper part 142 ' and low portion 144 ', and is pressed onto by two threaded fasteners (only show one of them in Figure 30 of accompanying drawing) online 146 ' place and adjoins each other.

The upper part 142 ' of the plurality of fan blade 140 ' and deflector surface 139 ' and fan/turbine unit 88 ' forms. The low portion 144 ' of fan/turbine unit 88 ' is provided with lower plate member 364, and in the separator 2 ' assembled, lower plate member 364 is arranged in the plane being perpendicular to center axis 64 ' and striding across the lower opening that the flowing-path 92 ' to turning axle 78 ' opens wide. However, plate member 364 and lead to flowing-path 92 ' described opening between separate, to allow fluid to flow into described opening.

Plate member 364 is provided with four apertures 366, and aperture 366 is equidistantly located along the imaginary circles centered by center axis 64 ' in the separator 2 ' assembled. It will be understood by persons of ordinary skill in the art that the aperture 366 that can use alternative quantity, but aperture should be arranged to guarantee the spin balancing of fan/turbine unit 88 '.

Importantly, aperture 366 is positioned at the radial outside of the opening leading to flowing-path 92 '. It is to be understood that therefore, this layout makes the cavity that the mist that oil drips can upwards flow through aperture 366 from turbine housing and thus enter in fan/turbine unit 88 ', and upwards flows through the flowing-path 92 ' of turning axle 78 '. But, also by understanding being flowing in radially inside direction from aperture 366 to the described opening of flowing-path 92. In use separator 2 ' period, fan/turbine unit 88 ' rotates up in the side that arrow 134 ' indicates certainly, and the mist that oil drips radially inwardly can flow to flowing-path 92 ' from aperture 366 simultaneously, flow through the relatively large oil of the ratio in aperture 366 laterally to move in direction by the plate member 364 of spin, and tend to be dished out by the outward opening away from flowing-path 92 '. Such as, at inclination of vehicle or in addition so that upwards spattered fuel-displaced so that the mode pouring the cavity of fan/turbine 88 ' moves by aperture 366 from turbine housing, tend to for the sidewise movement of the oil imparting in described cavity to prevent described oil inwardly turning axle 78 ' flow. Therefore avoid a large amount of oil undesirably upwards to flow through turning axle 78 ' and enter dish stacking 84 '.

Plate member 364 provides two discharge orifice 368, to allow oil to return to turbine housing from the cavity discharge in fan/turbine unit 88 '. Discharge orifice 368 is positioned to diametrically relative to each other, and forms groove in plate member 364 and in the general cylindrical wall erect from the circular periphery of described plate member 364. The position of the discharge orifice 368 in the radially portion part of turbine cavity guarantee away from turning axle 78 ' dish out described cavity neighboring oil really effectively discharge from fan/turbine unit 88 '.

Although the low portion 144 ' showing plate member 364 and fan/turbine unit 88 ' in the embodiment of Figure 29 and 30 is one, but in the alternative shown in Figure 31 and 32 of accompanying drawing, end plate 364 provides as the circular discs being separated with the low portion 144 of fan/turbine unit 88 '. With reference to Figure 31 and 32, it will be seen that the plate member 364 of the separation of alternative be by with Figure 29 with 30 in identical in the way of be provided with the circular discs in aperture 366. But, alternative plate member 364 is in position relative to the residue part of fan/turbine unit 88 ' by threaded fastener 362 (extending through them), and does not have discharge orifice 368. In this alternative arrangement, only providing discharge orifice 368 in the cylindrical wall of low portion 144 ', it is arranged to concentric with the circular periphery edge of plate member 364 and upwards extends from this edge. The low portion 144 ' of fan/turbine unit 88 ' is provided with the 2nd cylindrical wall 370 in addition, 2nd cylindrical wall 370 be positioned at the cavity of fan/turbine unit 88 ' and extend downwards so as to provide towards under annular surface, can by two threaded fasteners 362 facing to these annular surface pressing plate parts 364. Towards under annular surface in recess is provided, to provide fluid path 372 between described cylindrical wall 370 and plate member 364. In use, the oil of the upper surface flowing outwardly through plate member 364 is sent to discharge orifice 368 via flowing-path 372.

Although the fan/turbine unit 88 ' of Figure 31 and 32 is provided with the outer cylindrical wall together defining cavity and plate member 364, and also it is provided with the other cylindrical wall 370 that plate member 364 abuts against its location in addition, but fan/turbine unit 88 other side be similar to prior art separator 2 in, and by with prior art separator 2 in identical in the way of be fixed to turning axle 78 '. Specifically, fan/turbine unit 88 ' is fixed to turning axle 78 ' by means of packing ring 133 ', and upper and by means of the peripheral recess on the outside surface being arranged in turning axle 78 ' the back-up ring 132 of low portion 144 ' that packing ring 133 ' is upwards pressed in described unit 88 ' is held in place. It is to be understood that packing ring 133 ' and back-up ring 132 provide alternative fixing means for the compression spring 360 shown in Figure 29 and 30 and back-up ring 132.

About first group of internals, supporting plate 70 ' has round-shaped, and this is round-shaped has the substantially equal diameter of the diameter with rotor shell 4 '. As in prior art separator 2 ', relative geometry so to such an extent as to allow supporting plate 70 ' the lower end of rotor shell 4 ' be positioned at towards under shoulder 148 ' on. By this way, the lower open end of rotor shell 4 ' is closed by supporting plate 70 '. But, in the separator 2 ' improved, the lower open end of rotor shell 4 ' adjoins the upside of supporting plate 70 ' and is provided with peripheral recess 260, and this peripheral recess 260 is for receiving O sealing member 262 (see Figure 34). It is to be understood that the 2nd O sealing member 262 ensure that the sealing of the fluid between rotor shell 4 ' and supporting plate 70 '.

In addition, in the separator 2 ' assembled, circumferential edge surface, radially portion 630 (formation reference plane) registration of supporting plate 70 ' becomes the cylindrical internal surface 632 with the lower open end around rotor shell 4 ' to adjoin. By this way, supporting plate 70 ' is laterally aligned in the final position (see Figure 13) of expectation relative to rotor shell 4 '.

Supporting plate 70 ' is also provided with central circular aperture, and in the separator 2 ' assembled, central circular aperture is concentric with rotor shell 4 '. In other words, in the separator 2 ' assembled, the circular central aperture of supporting plate 70 ' is centered by the center axis 64 ' of rotor shell 4 '. In addition, as will be apparent especially from Figure 34 of accompanying drawing, bottom bearing unit 90 ' be received in the center port of supporting plate 70 '. The radially portion part of bottom bearing unit 90 ' is fixed relative to supporting plate 70 '. The radial penetralia part of bottom bearing unit 90 is positioned near turning axle 78 ', but not fixed thereon.

As previously discussed, first group of internals also comprises the housing plug-in unit 72 ' being fixed to definitely on supporting plate 70 '. As, in prior art separator 2 ', housing plug-in unit 72 ' works and makes Purge gas isolate with the oil therefrom isolated. The housing plug-in unit 72 ' of the separator 2 ' improved additionally provides the outlet 150 ' for Purge gas, and this outlet 150 ' is directly connected with cylindrical inlet part 211 (see Figure 15) the sealing ground of valve cell housing 12 '.

Housing plug-in unit 72 ' provides as the moulded piece of the one of plastic material. But, when following description housing plug-in unit 72 ', will think that plug-in unit comprises four parts: the outside deflector wall 264 with the shape of conical butt; There is the abutment wall 266 of cylindrical shape; There are the isolating roof parts 268 of the shape of conical butt; And limit the exit portion 270 of described plug-in unit outlet 150 ' (seeing Figure 27 and 28 especially).

The isolating roof parts 268 of housing plug-in unit 72 ' have the shape of conical butt and are bearing in abutment wall 266. Isolating roof parts 268 are provided with central circular aperture, and in the separator 2 ' assembled, this central round orifice mouthpiece has the center axis that the center axis 64 ' with rotor shell 4 ' overlaps. The upper surface of isolating roof parts 268 provides elongated channel/recess 272 (see Figure 28). This path/recess 272 defines the fluid path for Purge gas, and it extends to the exit portion 270 (having tubular form) of housing plug-in unit 72 ' from the entrance 282 of recess 272. Entrance 282 is limited by the recessed circumferential portion at the upper circular periphery edge 274 of isolating roof parts 268. Entrance 282 is positioned to the exit portion 270 with housing plug-in unit 72 ' substantially diametrically. The arc 280 of about 80 �� aforementioned recessed of the part extend through of described periphery edge 274, this arc is centered by the described center axis in housing plug-in unit aperture. In an alternative embodiment, the entrance of fluid path can be limited by the recessed part of the different arc (such as between 45 �� and 110 ��) of the extend through in described periphery edge 274. In the separator 2 ' assembled, only little distance separates isolating roof parts 268 and end plate 86 '. Result, thinking that the major part of Purge gas in the region 606 entered between isolating roof parts 268 and end plate 86 ' is done (entering) like this by the space between the aforementioned recessed part of described periphery edge 274 and end plate 86 ', only relative small portion Purge gas is divided through the remainder of described periphery edge 274 and is flowed into described region.

It will be appreciated that, therefore space between whole circumference periphery edge 274 and end plate 86 ' provides the entrance 610 in the described region 606 between isolating roof parts 268 and end plate 86 ', but because the part 612 of a length direction of this entrance 610 is (namely, the entrance 282 of path/recess 272) there is the bigger degree of depth 613 (namely than the part of other length direction of entrance 610, bigger axial spacing between periphery edge 274 and end plate 86 '), so most of Purge gas flowing into described region 606 is done like this by the part 612 of the described length direction with the bigger degree of depth 613. the degree of depth of the part of remaining length direction of described area entry (610) is minimum, so that minimumization is through their liquid flow, and thus also minimum oil drips passing through through them. the degree of depth of the part of remaining length direction can between 1/10th and half of the bigger degree of depth 613, but 1/3rd of the bigger degree of depth 613 described in being preferably.

In use separator 2 ' period, the Purge gas leaving separator disks stacking 84 ' flows downward with internal surface along the cylindrical wall of rotor shell 4 ' of the rotary motion spiraled. It is to be understood that the Purge gas therefore entering the aforementioned areas 606 between isolating roof parts 268 and end plate 86 ' is tended to utilize the rotary rotational flow motion centered by the center axis 64 ' of rotor shell 4 ' to do like this. But, the gas stream entering described region 606 via entrance 282 is directed to plug-in unit outlet 150 ' immediately by means of the sidewall 276,278 of elongated recesses 272. Also think that this kind of guiding of Purge gas stream can reduce the rotary rotational flow motion of Purge gas immediately after described gas enters described elongated recesses 272 via recess entrance 282. With regard to this point, from Figure 28 of accompanying drawing it will be seen that, the upstream portion of elongated recesses 272 is the bending (sidewall 276 of recess 272,278 thus align with the inlet fluid of eddy flow, so that the pressure (unpressure) of going that minimumization caters to the need significantly when fluid impacts sidewall 276,278 at first is lost) and straighten gradually when downstream along recess 272 towards plug-in unit, outlet 150 ' is mobile at fluid. Think compared with above-described prior art separator 2, enter the region between isolating roof parts 268 and end plate 86 ' cleaning gas major part in the minimizing immediately of swirling motion can reduce the pressure-losses in the fluid of this part that flow through separator 2 ' significantly.

To understand, but the Purge gas not flowing through entrance 282 entering the region between isolating roof parts 268 and end plate 86 ' in other position of the periphery along isolating roof parts 268 will be tended to flow through described region with swirling motion, until receiving by elongated recesses 272, hereafter, think that particularly radially outer sidewall 276 will guide fluid to export 150 ' towards plug-in unit, and reduce the swirling motion of described fluid.

Cylindrical abutment wall 266 is arranged with one heart with the central circular aperture in isolating roof parts 268, and gives prominence to downwards from the downside of isolating roof parts 268. The diameter of abutment wall 266 is less than the diameter of the periphery edge 274 of isolating roof parts 268. In the separator 2 ' assembled, abutment wall 266 towards under the adjacent supporting plate 70 ' (junction surface place between which) of lower circular edge 450 (see Figure 27). Isolating roof parts 268 are thus bearing on supporting plate 70 ' by abutment wall 266, and guarantee the correct axial location of isolating roof parts 268 relative to supporting plate 70 '. Abutment wall 266 is also provided with multiple cylindrical lug boss 452, and they have the recess for receiving fastening piece 74 ' threadably separately. In the separator 2 ' assembled, each fastening piece 74 ' is extended in described lug boss 452 from the lower section of supporting plate 70 ' by the aperture supporting plate 70 '. By this way, package case 72 ' is fixed on supporting plate 70 ' definitely.

Abutment wall 266 towards under lower circular edge 450 be provided with the multiple aperture/recesses 454 being positioned at multiple position along described edge 450. As seen from Figure 27 and 34 especially, recess 454 provides space between abutment wall 266 and supporting plate 70 ', is using the separator 2 ' period assembled, and fluid can flow through this space. Specifically, in use separator 2 ' period, the oil isolated radially inwardly flowed from the cylindrical wall of rotor shell 4 ' along supporting plate 70 ' is through multiple recess 454. A part for Purge gas also radially inwardly flows through the upper surface (technician it will be appreciated that) of supporting plate 70 ', and this fluid also flows through multiple recess 454. This liquid flow is indicated by the arrow 188 ' in Figure 34.

Outside deflector wall 264 extends downwards from the periphery edge 274 of isolating roof parts 268. Deflector wall 264 has the shape of the conical butt that edge is dispersed from isolating roof parts 268 towards supporting plate 70 ' in the separator 2 ' assembled in downward direction. Diameter that deflector wall 264 is located at its upper end (and therefore, the diameter of the periphery edge 274 of isolating roof parts 268) equals the external diameter of separator disks stacking 84 ' substantially. Due to the shape of the conical butt of deflector wall 264, when along, when in downward direction moving, deflector wall 264 is assembled about the general cylindrical wall of rotor shell 4 '. The sectional area of the flowing-path between deflector wall 264 and rotor shell 4 ' (that is, in a downward direction) reduces therefore in the flowing direction. The lower free end 608 of deflector wall 264 be positioned to and rotor shell 4 ' cylindrical wall between separate, and separate between 2 millimeters and 200 millimeters between supporting plate 70 ' top and the preferred distance 456 of 14 millimeters. Outside deflector wall 264 allows the oil (or other material being separated) isolated and Purge gas (it does not enter first area entrance 610) to flow downward along the cylindrical wall of rotor shell 4 ' with this kind of interval of rotor shell 4 ' and supporting plate 70 ', and radially inwardly flows through deflector wall 264 (comprising its free end) along supporting plate 70 '. Like this, the oil isolated and Purge gas flow through the 2nd region 614 on the side contrary with the first flow region 606 of housing plug-in unit 72 '.

And, due to the shape of its conical butt, when moving in downward direction, outside deflector wall 264 is dispersed from cylindrical abutment wall 266. Outside deflector wall, isolating roof parts 268 and cylindrical abutment wall 266 limit the cavity 458 (see Figure 34) of the cardinal principle annular shape with unlimited lower end. This layout so to such an extent as to reduce the oil isolated along rotor shell 4 ' be downward through recess 272 entrance 282, only due to fluid recirculation and subsequently to upper flowing and thus flow into the possibility that described entrance 282 carrys out removing pollutant gas.

More particularly, although the oil that the relatively large spacing between the upper end of rotor shell 4 ' and deflector wall 264 allows to isolate easily enters between these features, but the smaller spacing at the lower free end of deflector wall 264 between these features can reduce the oil isolated can upwards be splashed into or be recycled to the easiness between described free end and rotor shell 4 '. In addition, any recirculation of fluid near the radial outer periphery of supporting plate 70 ' will tend to the oil inflow abovementioned cavity 458 that causes isolating. Such as, the oil isolated upwards can flow along the radially-outer surface of cylindrical abutment wall 266, along isolating roof parts 268 downside outwardly, and then flow downward along the inner radial surface of deflector wall 264. When suitable, oil may be fallen supporting plate 70 ' from cavity 458 under gravity. It will be appreciated that this recirculation flow path can not cause the oil isolated upwards to flow in the way of causing the risk of the Purge gas in the region polluted between inflow isolating roof parts 268 and end plate 86 '. Therefore, once (namely Purge gas flows through region 606 entrance towards supporting plate 70 ', lead to the entrance between isolating roof parts 268 and end plate 86 '), the any recirculation subsequently just preventing described gas to return to upstream towards described entrance causes the gas (and the oil carried by it drips) of recirculation to enter described region 606 by deflector wall 264, this can isolate gas and the described entrance (that is, keeping it to be separated) of described recirculation effectively.

The exit portion 270 of housing plug-in unit 72 ' is provided as cylindrical tubulose element, this cylindrical tubulose element opens wide (and more specifically to the upper surface of isolating roof parts 268, open wide to for receiving the recess 272 of Purge gas), and extend through abutment wall 266 and outside deflector wall 264 in direction radially substantially. As will be obvious especially from Figure 13 of accompanying drawing and 14, exit portion 270 be positioned at abutment wall 266 towards under edge on. Therefore, in the separator 2 ' assembled, exit portion 270 is positioned at supporting plate 70 ' top so that fluid can at exit portion 270 flowing underneath. Advantageously, the oil isolated can at exit portion 270 flowing underneath, and therefore, be not inclined to the periphery edge 274 towards isolating roof parts 268 climb exit portion 270 outside surface on, herein, the oil isolated easily can flow into the cleaning gas of the recess 272 of housing plug-in unit 72 ' by ground contamination. Exit portion 270 at it, to one end that recess 272 opens wide, free end at a distance is provided with supporting member 460, supporting member 460 is outstanding downwards from the bottom part of described free end, so that adjacent supporting plate 70 '. By this way, supporting member 460 contributes between supporting plate 70 ' and exit portion 270 minimally spacing, but also allows supporting plate 70 ' to provide supporting to the free end of exit portion 270.

During assembling, separator 2 ' by be above fixed to turbine housing (not shown) about in the way of similar described by prior art separator 2 '. Specifically, the separator 2 ' improved is fixed to turbine housing by means of four threaded fastening piece (not shown)s, and each threaded fastening piece is through the different lug boss (seeing Figure 18 and 29 especially) in four lug bosses 284 integral from the lower end of rotor shell 4.

It will be appreciated by those skilled in the art that, as when prior art separator 2, supporting plate 70 ' (and therefore, all components in first group of component and the 2nd group of component) remain by means of turbine housing and to be in required position relative to rotor shell 4 ', after rotor shell 4 ' and turbine housing are fastened to and go up each other, this turbine housing supporting plate 70 ' is depressed into towards under shoulder 148 ' adjacent. Supporting plate 70 ' substantially threaded fastening piece by means of extend through four lug bosses 284 be clamped between rotor shell 4 ' and turbine housing 178 '. Along with threaded fastening piece is tightened and makes supporting plate 70 ' and shoulder 148 ' to occur to adjoin, result, the O sealing member 262 at described shoulder 148 ' place is pressed in the recess 260 being associated, and the 2nd helical compression spring 130 ' is compressed by top axle bearing unit 50 '.

In the operation of the separator 2 ' improved, the jet of oil is directed on turbine wheel 136 ' by the nozzle (not shown) in turbine housing, to rotate up turbine wheel in the side that arrow 134 ' (see Figure 29 and 34) indicates. This rotary actuation rotor assembly of turbine wheel rotates up around the center axis 64 ' of rotor shell 4 ' in the side of arrow 134 ' as a whole. In other words, turning axle 78 '; Upper rotor part dish 80 '; Stacking the 84 ' of separator disks 82 '; Fan disk 240; End plate 86 '; Splash plate dish 242; And the fan of combination and turbine unit 88 ' (that is, being jointly called rotor assembly herein) as a whole assembly rotary shell 4 ' in and relative to described housing 4 ' and supporting plate 70 '; Housing plug-in unit 72 '; And turbine housing rotates together.

Release from engine housing and need the gas processed by separator 2 ' to be introduced into separator 2 ' via the fluid intake 8 ' at the top being arranged in rotor shell 4 '. As the arrow 68 ' in Figure 34 indicates, inlet gas enters rotor shell 4 ' along direction that is parallel with center axis 64 ' and conllinear, and flows through three in top axle bearing unit 50 ' groove 66 ' before flow into the entrance 600 of rotor assembly through 12 spokes 116 ' of upper rotor part dish 80 '. The rotary motion of 12 spokes 116 ' also can cause the sidewise movement of the fluid between described spoke, because described fluid tangentially moves from the circular path of spoke 116 ', and is effectively outwards dished out towards the cylindrical wall of rotor shell 4. Substantially, 12 spokes 116 ' give cylindrical motion on inlet gas.

Inlet gas is downward through the spoke 116 ' of upper rotor part dish 80 ' and separator disks 82 ', 126 ', this gas laterally moves towards the cylindrical wall of rotor shell 4 ' via the space 602 between adjacent separator disks 82 ', as shown in the arrow 184 ' in Figure 34. By along this path, the direction of liquid flow changes more than 90 ��.

It is to be understood that the space 604 between the radially portion circumferential edge of adjacent separator disks 82 ' represents the outlet of rotor assembly jointly.

Those skilled in the art it will also be understood that oil drip 186 ' tend to they move through separator disks and by the cylindrical wall of rotor shell 4 ' of dishing out time pool together and formed bigger dripping. Once receive by described cylindrical wall, oil drips 186 ' and just tends to advance on supporting plate 70 ' under gravity downwards. Separate between the most external circumferential edge of separator stacking 84 ' is fully inside relative to the cylindrical wall of rotor shell 4 ', do not advance on described supporting plate 70 ' downwards to allow oil to drip not interruptedly. O sealing member 262 is guaranteed that oil drips and can not be flowed between supporting plate 70 ' and rotor shell 4 '.

It will be appreciated by those skilled in the art that, due to the rotary motion of rotor assembly, the hydrodynamicpressure in rotor shell 4 ' the peripheral edge place of supporting plate 70 ' and separator disks stacking 84 ' than the abutment wall 266 of housing plug-in unit 72 ' and top board parts 268 and supporting plate 70 ' around region in bigger. As a result, the cylindrical wall of Purge gas along rotor shell 4 ' is tended to exist downwards and along the radially inside flowing of supporting plate 70 '. This liquid flow tends to be dripped on the supporting plate 70 being pushed to lower section downwards by the oil isolated along cylindrical wall, and then radially inwardly promotes the aperture in its abutment wall 266 passing through housing plug-in unit 72 ' along supporting plate 70 '. This gaseous fluid stream indicates (see Figure 34) by arrow 188 '. Gaseous fluid stream radially-inwardly moves through the upper surface of supporting plate 70 ' towards the central round orifice opening's edge in housing plug-in unit 72 '. This stream crossing supporting plate 70 ' tends to be dripped by the oil isolated towards bottom bearing unit 90 ' push through supporting plate 70, and described oil drips can through bottom bearing unit 90 '. The fan blade 140 ' of the fan of combination and the rotation of turbine unit 88 ' tends to the static pressure reduced in the region of bottom bearing unit 90 ' in turbine housing (rotor shell 4 ' is attached on it during use), so that suction oil drips by bottom bearing unit 90 '. Fan blade 140 ' is then radially thrown into turbine housing by described, from, turbine housing, they can return engine crankshaft housing. Meanwhile, the gaseous fluid flowing through supporting plate 70 ' is drawn upwardly the center port inhaled by package case 72 ', to pass radially outwardly through between end plate 86 ' and fan disk 240. Gaseous fluid, then by flowing through the described cylindrical part 211 of valve cell housing 12 ' and leave rotor shell 4 ', is connected to housing plug-in unit 72 ' to the sealing of this part 211, and through housing plug-in unit outlet 150 ' and rotor shell outlet 10 '.

With reference to accompanying drawing it will also be appreciated that, except flowing and the aperture in flowing through the abutment wall 266 of housing plug-in unit 72 ' on the upper surface of supporting plate 70 ', some in Purge gas flow to described cylindrical part 211 via the alternative route between the downside of end plate 86 ' and the upside of the isolating roof parts 268 of housing plug-in unit 72 '. This alternative route is indicated by arrow 190 '.

It will be appreciated that as, in the separator 2 of prior art, there is on bearing unit useful lubricant effect by the oil stream of the bottom bearing unit 90 ' of the separator 2 ' improved. Top axle bearing unit 50 ' is lubricated similarly by the oily mist naturally appeared in turbine housing and be upwards sent to top axle bearing unit 50 ' by the longitudinal flow path 92 ' of extend through turning axle 78 '.

The separator 2 ' of the improvement that prior art ALFDEX separator 2 or more describes can comprise the alternative devices for rotating turning axle 78 ' as shown in Figure 35 of accompanying drawing. With reference to Figure 35, it will be seen that the Pelton impeller turbine described is replaced by brushless electric motor 380 before, the rotor 382 of this brushless electric motor 380 is at the lower end of supporting plate 70 " lower section is fixed to turning axle 78 ". Electronic motor 380 shown in Figure 35 drives prior art ALFDEX separator 2. But, as will be understood by those skilled, the electrical motor driven shown in Figure 35 is arranged and also can be used in conjunction with the separator 2 ' of improvement described above.

With reference to Figure 35, it will be seen that the electronic motor 380 that electrical motor driven is arranged is arranged in by means of the housing 384 that multiple threaded fastener 180 ' (Figure 35 only show one of them) is fixed on rotor shell 4. Motor shell 384 is made up of upper part 386 and low portion 388, and they utilize suitable fastening device to be fixed on and go up each other, and have the O sealing member 390 of the interface between them. Other impurity that O sealing member 390 prevents dirt, water and/or is arranged in housing 384 outside undesirably leaks into the space of housing 384. By this way, electronics component (comprising printed circuit board (PCB) and/or other circuit) is kept apart with causing the material of the damage to them and fault subsequently.

The upper part 386 of housing 384 is provided with in described upper part 386 to limit the outstanding cylindrical wall 392 of center port downwards. Cylindrical wall 392 is arranged in the separator assembled with turning axle 78 " to locate with one heart. Deflection packing ring 139 " by back-up ring 404 " remains on turning axle 78 " on. Deflection packing ring 139 ' is thus upwards pressed against on the inner radial bearing seat ring of bottom bearing unit, as in prior art ALFDEX separator 2. Deflection packing ring 139 " there is radial outer periphery edge, itself and cylindrical wall 392 radially between separate, to allow contaminated oil from passing through between them.

The upper end of the other separate section 394 (having the shape of conical butt substantially) of motor shell 384 is positioned at the lower end of the cylindrical wall 392 of upper part 386 and is sealed on this lower end. Sealing between cylindrical wall 392 and frusto-conically shaped portion 394 defines closed loop shape, and provides by means of other O sealing member 396. The low portion 388 that the lower end (having the diameter bigger than its upper end) of frusto-conically shaped portion 394 abuts against motor shell 384 by means of another O sealing member 398 seals. Sealing also defines closed loop shape.

Therefore, on the side of frusto-conically shaped portion 394, described part 394 and low portion 388 thus form space, and electronic motor 380 is positioned at wherein, and turning axle 78 " lower end extend to wherein. On another side of frusto-conically shaped portion 394, the remainder of described part 394 and upper part 386 and low portion 388 divides formation overall by around the space/compartment 406 with sealing, electronic/electrical gas component is (such as, printed circuit board (PCB) 408) it is contained in wherein, electric power and control signal to be supplied to electronic motor 380. Compartment 406 is not only opened relative to the outside seal of motor shell 384, but also is positioned at space sealing wherein relative to electronic motor 380 and opens. Therefore prevent the contaminated oil flowing through this space when use separator from close to electronic/electrical gas component and the damage to them can be caused.

In addition, frusto-conically shaped portion 394 is provided with aperture (not shown), and electrical lead 410 (connecting motor 380 and described electric supply/control component) extends through this aperture and described wire is sealed on this aperture.

Junctor 412 also extends through the aperture 414 in motor shell 384, to allow outside that one or more electrical lead (not shown) is positioned at separator (such as, it is used for vehicle wherein with separator to be associated), to be connected to the described electric supply/control component being contained in compartment 406. In other words, electrical lead or multiple electrical lead can be provided with for the plug being mechanically connected with junctor 412 and be electrically connected. This wire or multiple wire can carry the electric power for electrical motor driven layout and/or control signal. Junctor 412 is sealed on housing 384, to prevent impurity from undesirably invading in compartment 406.

Although compartment 406 has the cardinal principle annular shape concentric with the rotor assembly of separator, but it will be understood that compartment 406 can have different shapes.

The stator 400 of electronic motor 380 is fixed to the low portion 388 of motor shell 384. The inner radial forming the described frusto-conically shaped portion 394 of sealing with cylindrical wall 392 defines the aperture of the substantially equal diameter of the inner most diameter with the stator 400 with electronic motor 380.

During the separator using the electrical motor driven being provided with Figure 35 to arrange, supply of electric power is connected to brushless electric motor 380, to operate its rotor 382 and thus to make turning axle 78 " rotates. As above set forth, the oil isolated transports through bottom bearing unit 90 downwards from rotor shell 4. In the separator that the electrical motor driven being provided with Figure 35 is arranged, this oil isolated is discharged to the inside of motor shell 384 from bottom bearing unit, and in the space of the cylindrical wall 392 being more particularly discharged in upper case portion 386. Then the oil isolated transports through the rotor 380 of electronic motor 380 and leaves motor shell 384 via being positioned at the port 402 below electronic motor 380 in lower housing section 388. The operation of electronic motor 380 can not adversely be affected, because the electrical lead of stator 400 is covered by one layer of epoxy resin varnish through rotor 382 (or through the space rotor 382 and stator 400) and the oil that comes in contact with described rotor 382 and stator 400.

Further about the manufacture of the separator 2 ' improved, and particularly about being assembled in rotor shell 4 ' by top axle bearing unit 50 ', now Figure 37 to 41 of accompanying drawing is carried out reference. These figures show that the technique for being spun welded on rotor shell 4 ' by top axle bearing unit 50 ' on such as upper/lower positions: supporting plate 70 ' be assembled into lower end shoulder with rotor shell 4 ' 148 ' adjacent time, align vertically with bottom bearing unit 90 ' in this position. Despite this rotor shell 4 ' after the injection-molded by described housing 4 ' warpage caused by geometry change, assembling technique still ensure that axially aligning of top axle bearing unit 50 ' and bottom bearing unit 90 '.

This technique uses spin welding fixture 500, it rotor portion 504 comprising stationary part 502 and being rotatably installed on stationary part 502. Stationary part 502 comprises circular discs 506, and it has the diameter equal with supporting plate 70 '. The geometry of circular discs 506 so to such an extent as to allows described circular discs 506 to be positioned to adjoin (as shown in Figure 40) with rotor shell 4 ' in the way of identical with supporting plate 70 ' in the separator 2 ' assembled. Rotor portion 504 comprises the center extending through circular discs 506 and is oriented orthogonal to the axle 508 of described circular discs 506. Axle 504 is installed relative to circular discs 506 by means of bearing assembly (not shown).

One end of axle 508 is provided with the head 510 for receiving top axle bearing unit 50 '. As concentric with the circular discs 506 of stationary part 502 and by rotor portion 504 rotate around axis centered by circular discs head 510 is provided. The diameter of head 510 equals the diameter of the inner radial surface of the outstanding cylindrical wall 58 ' of top axle bearing unit 50 ' substantially downwards. By this way, the cylindrical wall 58 ' of top axle bearing unit 50 ' can be positioned at around head 510, wherein has little between top axle bearing unit 50 ' with axle 508 or does not have relative sidewise movement. Relative rotary motion between top axle bearing unit 50 ' and axle 508 is prevented by the protuberance 512 erect from the circular discs of head 510. Head 510 comprises three protuberances 512, and they are mutually the same and separate between equidistantly around the rotation of axle 508. Protuberance 512 has part circular shape separately, and position and size are set to be positioned in the part circular groove 66 ' of top axle bearing unit 50 '. Protuberance 512 is basic identical with described groove 66 ' size and shape, and therefore, when protuberance 512 is received by described groove 66 (seeing Figure 37 and 38 especially), substantially prevent the rotary motion of top axle bearing unit 50 ' relative to the head 510 of axle 508.

The 2nd end in the distant place, one end being provided with head 501 of axle 508 is provided with for rotor portion 504 being connected to motor to drive rotor portion 504 relative to the device 514 of the rotary motion of stationary part 502.

Having illustrated spin welding fixture 500 in Figure 39 of accompanying drawing, this spin welding fixture 500 has the top axle bearing unit 50 ' being positioned on its head 510. When top axle bearing unit 50 ' is positioned on head 510, axle 508 and top axle bearing unit 50 ' are inserted in rotor shell 4 ', as shown in Figure 40. Circular discs 506 is positioned to the lower shoulder 148 ' of adjacent rotor shell 4 '. More particularly, circumferential edge surface, radially portion 634 (formation reference plane) registration of circular discs 506 becomes the cylindrical internal surface 632 with the lower open end around rotor shell 4 ' to adjoin. By this way, it is determined that the lateral register of top axle bearing unit 50 ' relative to rotor shell 4 '. Utilizing the spin welding fixture 500 being positioned at rotor shell 4 ' by this way, the rotation of rotor portion 504 overlaps with the center axis 64 ' of the rotor shell 4 ' described before.

Rotor portion 504 can be arranged to can move in the axial direction relative to stationary part 502, make top axle bearing unit 50 ' second position can be moved to from first location, in first location, separate between the upper part of described bearing unit 50 ' and rotor shell 4 ', in the second position, bearing unit 50 ' is forced into at the upper convex ridge 238 adjacent (see Figure 34) provided of rotor shell 4 '. Top axle bearing unit 50 ' is being assembled into rotor shell 4 ' upper period, rotor shell 4 ' keeps fixing, and simultaneously the circular discs 506 of stationary part 502 is positioned to the lower shoulder 148 ' with rotor shell 4 ' and adjoins, rotor portion 504 is to rotate relative to high speed, and move in rotor shell 4 ' further vertically, so as to make spin/rotate top axle bearing unit 50 ' contact with described convex ridge 238. The top axle bearing unit 50 ' of spin is pressed against convex ridge 238 strongly, to produce heat of friction, and thus makes the abutment surface melting of the plastic material of top axle bearing unit 50 ' and convex ridge 238. Leaning on convex ridge 238 to extrude while bearing unit 50 ', the rotary motion of axle 508 reduces rapidly and stops, to allow bearing unit 50 ' and convex ridge 238 to be bonded to each other when the plastic material cools down of melting. Top axle bearing unit 50 ' and rotor shell 4 ' are thus spun welded to be gone up each other.

Rotor shell 4 ' can keep fixing (see Figure 40) by means of the lug boss 284 in extend through rotor shell 4 ' and the threaded fastener that extends in cylindrical erecting frame 516 during spin-welding process.

After top axle bearing unit 50 ' has been fixed on rotor shell 4 ', so that it may remove spin welding fixture 500 from rotor shell 4 '. Top axle bearing unit 50 ' thus keeps correctly locating and being fixed on rotor shell 4 ', as shown in Figure 41 of accompanying drawing. It is to be understood that top axle bearing unit 50 ' is positioned at the position being in center relative to the lower circular shoulder 148 ' of rotor shell 4 '. Therefore, when the internals of separator 2 ' is positioned at housing 4 ', supporting plate 70 ' leans on the adjacent of described shoulder 148 ' to ensure that bottom bearing unit 90 ' is also medially located about described shoulder 148 '. Although have after injection-molded rotor shell 4 ' any before warpage, top axle bearing unit 50 ' and bottom bearing unit 90 ' still align therefrom vertically.

Compared with prior art separator 2, by means of some module/component (see Figure 36) that it can exchange in different separator systems, the versatility of the separator of improvement is strengthened. It is hereinbefore described the ability that rotor shell 4 ' (that is, the module of a kind of particular type) receives different valve cell 14 ' (that is, the module of another multi-form type). This modularization measure by multi-form given type, such as, there is the module/component (valve cell 14 ') for the same characteristic features being connected with other module/component/engaging realize. By way of illustration, separator system can use the one in several multi-form valve cell potentially, even if because these multi-form common features being provided with permission and also mating with rotor shell 4 ' when many other sides possibility is different at valve cell. How different component/module that the table that Figure 36 provides shows separator system selection of land can be provided with component/module or to exchange with multi-form component/module.

The invention is not restricted to above-described specific embodiment. Reader will be apparent for those skilled in the art for alternative arrangement and suitable material.
