With reference to Fig. 1, will see, the housing 12 of valve cell 14 is provided with the annular shoulder 18 of setting, and this shoulder 18 defines fluid issuing, and Purge gas is sent out from separator 2 by this fluid issuing.The annular shoulder 18 that valve cell housing 12 provides is substantially identical with the annular shoulder 6 that rotor case 4 provides.Due to their similitude, entrance shoulder 6 and outlet shoulder 18 can receive the inlet/outlet pipe joint with identical interface profile interchangeably.A this pipe joint 22 with 90 ° of elbows is shown in figure 3 with cross section.One end of pipe joint 22 is provided with the circumferential collar 24 defining annular recess 26.Annular recess 26 has such square edge profile and diameter, and this square edge profile and diameter allow it to receive casing annular shoulder 6,18 (this shoulder also has square edge) (mode to be adjacent).

Fig. 2 that shoulder 6 and the joint of inlet pipe joint 28 of rotor case 4 can refer to accompanying drawing finds out.To understand, the pipe joint 28 shown in Fig. 2 has the bent angle different from the pipe joint 22 of Fig. 3.

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

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

The fluid flow path provided by two pipe joints 22,28 comprises the elbow at the interior turning 40 with basic shortage radius separately.In prior art separator 2, angled pipe joint uses injection-molded (for joint for plastic tube) and the manufacture of die casting (for aluminium tube joint) technology.As easily understood from Fig. 4 (which show the molded of pipe joint 22), in order to allow respectively by the first and second arrows 46,48 indicated directions remove the first and second internal mode product sections 42,44, moulded parts sections 42,44 internally can not provide radius in turning 40.

With reference to Fig. 8, the aforementioned inner component held by rotor case 4 is described special in more detail now.

First, top axle bearing unit 50 is fixed on the inner surface of rotor case 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 regularly.The layout of top axle bearing unit 50 clearly illustrates in fig. 8, but in the environment of prior art separator 2 its also shown in Fig. 2 and 9.

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 case 4 in the separator 2 assembled laterally adjoins.Contribute to guaranteeing the correct lateral register of top axle bearing unit 50 relative to rotor case 4 with cylindrical wall 60 is adjacent.Second cylindrical wall 62 of rotor case 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 case 4.Top axle bearing unit 50 is fixed to rotor case 4 by means of three threaded securing member (not shown)s.The layout of separator 2 makes the rotation of top axle bearing unit 50 overlap with the central axis 64 of rotor case 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 shown in by arrow 68).Upper cap member 54 makes to deflect from the inlet fluid of cage bearing 52, but as will be understood by those skilled, the downside of the topmost part of cap member 54 also makes upwards to be advanced through armature spindle during use and enters lubricating oil mist deflection (in cage bearing 52) of top axle bearing unit 50.

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

First group of component comprises the support plate 70 of annular shape and is called the parts 72 of dish type of housing insert.Housing insert 72 is combined with support plate 70 and works isolated isolated oil and Purge gas before isolated oil and Purge gas leave rotor case 4.Support plate 70 is formed from steel, and housing insert 72 is made up of plastic material.Support plate 70 and housing insert 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 threaded fastener 74 is threadedly engaged with the lug boss 76 given prominence to downwards from the downside of housing insert 72.This first group of component will be discussed subsequently in this specification in more detail.

Second group of component form rotor assembly and comprise rotating shaft 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.This component of second group according to so that the mode preventing them from relative to each other rotating is fixed to is gone up each other.But second group of component is rotatably installed to first group of component by means of bottom bearing unit 90 (seeing Figure 10 especially).

The rotor assembly formed by second group of component will be described in more detail now.

Rotating shaft 78 is made up of metal material, and has ring section, to provide the fluid flow path 92 extended longitudinally along its whole length.When using separator 2, this flow path 92 allows oily mist upwards transport through rotating shaft from turbine shroud and be sent to top axle bearing unit 50, to lubricate the bearing of described unit 50.Annular disk (there is the cylindrical wall erect from its radially outer circumferential edge) flow restrictor element 93 of form be located at the described fluid flow path 92 of the upper end of rotating shaft 78 towards upper interior shoulder.Flow restrictor element 93 works and is reduced by the flow path area (thus providing nozzle) of rotating shaft 78 in the exit entering top axle bearing unit 50 from rotating shaft 78.

The outside of rotating shaft 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 remained on by component on rotating shaft 78.A this back-up ring 94 clearly shows that packing ring 95 abuts against this back-up ring 94 and adjoins in order to provide towards upper shoulder in figure 6.Spiral compression spring 96 adjoin packing ring 95 towards upper shoulder.Back-up ring 94 peripheral recess be positioned at wherein has enough width (that is, the size on the axial direction of recess), moves vertically along rotating shaft 78 (in recess) to allow back-up ring 94.This allows spring 96 that axial force is applied to bottom bearing unit 90.

Other recess is provided on the outer surface of rotating shaft 78, for being located by component and remaining 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 rotating shaft 78 in use.

Although the spoke parts of upper rotor part dish 80 and separator disks 82 have unlimited space between which, them are flow through vertically along rotating shaft 78 to allow fluid, but the spoke parts of end plate 86 are attached at their lower surface place and go up each other, so that anti-fluid is along rotating shaft 78 or be upward through end plate 86 or be 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 Frusto-conical geometry 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 it is thinner that technical staff will understand separator disks 82, to allow the dish of larger amt to be provided in relatively short stacking 84, but upper rotor part dish 80 and end plate 86 much thicker than separator disks 82, to provide rigidity at the two ends place of dish stacking 84, and compression axial force is allowed to be applied to the frusto-conically shaped portion of separator disks equably by upper dish 80 and end plate 86 thus.Compression stress more specifically by be upwards pressed in end plate 86 hub 98 downside on spiral compression spring 96 produce.

About compact disk stacking 84 between upper dish 80 and end plate 86, technical staff will understand, and the adjacent separator disks 82 in stacking 84 must keep being spaced apart from each other, to allow fluid to flow through separator 2.This interval of separator disks 82 provides by means of multiple ribs 100 (being called joint filling part) that the upper surface on the frusto-conically shaped portion of each separator disks 82 provides.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 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 rotating shaft 78 relative in only six feasible Angle Position of rotating shaft 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 be applied to the inc situation in interval of compression stress between adjacent separator disks 82 on dish stacking 84 by end plate 86 under.

In addition about the compression stress being applied to separator disks stacking 84, technical staff will understand, and this power is produced by spiral compression spring 96 and is applied on end plate hub 98.Due to the rigidity of end plate 86, compression stress is delivered to the frusto-conically shaped portion 108 of end plate 86 from hub 98 by multiple spokes 110 radially extended of end plate 86.Then compression stress 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).Compression stress is delivered to the hub 114 of upper rotor part dish 80 from frusto-conically shaped portion 112 by six spokes radially extended 116.Compression stress can be delivered to hub 114 due to the rigidity of upper rotor part dish 80 from frusto-conically shaped portion 112.What upper rotor part dish 80 pairs of compression stresses were reacted prevents (seeing Fig. 6 especially) along rotating shaft 78 axially-movable upwards by upper rotor part hub 114 being positioned in the peripheral recess 118 in the outer surface of rotating shaft 78.Frictional force between the outer surface of hub 114 and rotating shaft 78 prevents the relative rotation between them.

To see particularly from Fig. 6 and 8, the hub 114 of upper rotor part dish 80 is downward vertically extends to point directly over end plate hub 98 along rotating shaft 78.More particularly, hub 114 extends along the entire depth of separator disks stacking 84, and makes the hub 120 of each separator disks 82 be separated (see Fig. 7) with rotating shaft 78 thus.The hub 120 of each separator disks 82 has the hex shape limiting hexagon aperture, and rotating shaft 78 and upper rotor part hub 114 extend through this hexagon aperture.Separator hub 120 relative to upper rotor part hub 114 (and therefore, relative to rotating shaft 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 hexagon aperture limited by separator hub 120.This position of key 122 prevents separator hub 120 relative to the side direction of rotating shaft 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 remainder of the separator disks 82 be 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 indeformable.Technical staff will understand, and the compression stress that helical spring 96 produces passes through separator disks stacking 84 via joint filling part 100 instead of by separator plate convergence 126.

Technical staff also will understand, and the hexagon hub 120 of each separator disks 82 and the relative geometry of key 122 guarantee that described above each separator disks 82 can in only six Angle Position be positioned on rotating shaft 78.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: in the unjustified situation of joint filling part 100 of adjacent separator disks 82, separator disks stacking 84 is assembled on rotating shaft 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.Particularly about prior art separator 2, Fig. 1,2,8,9 and 10 simplify in an identical manner.

As shown in Figure 5, the position of the second peripheral recess 128 above the first recess 118 is provided in the upper end of rotating shaft 78.Second recess 128 receives the second spiral compression spring 130.The position of the second recess makes, in the prior art separator 2 assembled, the lower end of the second spring 130 and the hub 114 of upper rotor part dish 80 spaced apart (see Fig. 6), and the downward axially-movable of lower end along rotating shaft 78 preventing the second spring 130 towards upper shoulder by being formed by the second recess 128.In addition, in the separator 2 assembled, the cage of cage bearing 52 adjoins and compresses the second spring 130 (wherein the upper end of rotating shaft 78 and the cap member 54 of top axle bearing unit 50 keep Jian Ge Kai – to see Fig. 8 especially) downwards.Load applying to top axle bearing unit 50, and is reduced the vibration at top axle bearing unit 50 place and the wearing and tearing be associated by the second spring 130 thus.

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

The fan of combination and turbine unit 88 are fixed to the lower end of the rotating shaft 78 given prominence to from the downside of support plate 70 downwards.Fan/turbine unit 88 is held in place on the lower end of rotating shaft 78 by means of second packing ring 133 towards upper surface of the second back-up ring 132 (remaining in the 3rd peripheral recess in axle 78) and adjacent second back-up ring 132.The axial location of fan/turbine unit 88 on rotating shaft 88 determined by the second back-up ring 132 causes the upper surface of unit 88 to be forced into and deflects 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 inside race of bottom bearing unit 90 adjoins the first back-up ring 94 and the bias voltage of antagonism the first Compress Spring 96 upwards presses this back-up ring 94.Press inside race, deflection packing ring 139 and fan/turbine unit 88 so facing to the second back-up ring 132 to such an extent as to these elements remained on the fixing position of rotation relative to rotating shaft 78.

The rotor assembly of separator 2 rotates along arrow 134 (see Fig. 1) indicated direction by means of hydraulic impulse turbine.Fan/turbine unit 88 comprises Pelton impeller 136, and this Pelton impeller 136 has the multiple wheel blades 138 be 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 shroud 178.More particularly, jet guides along the tangent line of the circle through multiple wheel blade 138, makes this jet enter wheel blade (with its surface in alignment).Jet flows along the described surface of the in-profile following wheel blade, and is turned to by described profile afterwards, so that along the flowing of other surface, 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 support 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 rotating shaft 78.Fan blade 140 extends radially outward near bottom bearing unit 90.It will be understood by those skilled in the art that fan blade 140 rotates around central axis 64 when turbine wheel 136 rotates.Like this, fluid is dished out from the region between impeller 136 and the downside of support plate 70 by fan blade 140 effectively, thus the fluid pressure reduced in the region of bottom bearing 90, and isolated oil is pumped downwards by bottom bearing unit and is entered the turbine shroud 178 below support plate 70 by the position above support 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 adjacent to each other.

About first group of internals, support plate 70 is formed from steel and has round-shaped, and this is round-shaped has the diameter substantially equal with the diameter of rotor case 4.Relative geometry so to such an extent as to allow support plate 70 to be located on the prone shoulder 148 of the lower end of rotor case 4.By this way, the lower open end of rotor case 4 is closed by support plate 70.Support plate 70 is also provided with central circular aperture, and this central circular aperture is concentric with rotor case 4 in the separator 2 assembled.In other words, in the separator 2 assembled, the circular central aperture of support plate 70 is centered by the central axis 64 of rotor case 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 support plate 70.The radially portion part of bottom bearing unit 90 is fixed relative to support plate 70.The radial penetralia part of bottom bearing unit 90 is positioned near rotating shaft 78, but is not fixed to the upper.

As previously discussed, first group of internals also comprises the housing insert 72 be fixed to definitely on support plate 70.Housing insert 72 works separation purifying gas and therefrom isolated oil, and is provided for the outlet 150 of Purge gas, and this outlet 150 is connected (seeing Fig. 1 especially) with the exit aperture 10 of rotor case 4.Housing insert 72 is provided as the moulded piece of plastic material.But, when following description housing insert 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 columniform skirt portions 152 of housing insert 72 has the most external external diameter of the diameter of the inner wall section of the rotor case 4 substantially equaling adjacent with skirt portions 152.Peripheral recess 159 (see Figure 12) is provided in the outer surface of skirt portions 152, to receive O-ring packing 160, this O-ring packing 160 guarantees the Fluid Sealing between housing insert 72 chord transcapsidation body 4 in the separator 2 assembled.

The lower end of columniform skirt portions 152 adjoins the upside of support plate 70, and is provided with the peripheral recess 162 (see Figure 12) for receiving the second O-ring packing 164.To understand, the second O-ring packing 164 ensure that the Fluid Sealing between housing insert 72 and support plate 70.

Be positioned at the radially inner side of external skirt part 152 and the second cylindrical wall arranged is connected to skirt portions 152 at its lower end concentricly, to form ditch part 154.Ditch part 154 forms the annular ditch (or groove) 166 that cylindrical wall extends in rotor case 4 together with external skirt part 152.Ditch 166 has the cross section of U-shape, and during use separator 2, collect from separator disks 82 dish out and in the inside of rotor case 4 (and the effect of the gas flow spiraled downwards, as described in more detail herein) isolated oil droplet of advancing downwards under gravity.Ditch part 154 is provided with four discharge orifices 168 (seeing Figure 11 especially), the oil collected in ditch 166 flows by these four discharge orifices 168, so as use to transmit during separator 2 enter by the upside of the downside of housing insert 72 and support plate 70 around region.

The Part III 156 of housing insert 72 has Frusto-conical shape, and hangs from ditch part 154.Frusto-conically shaped portion 156 is provided with central circular aperture, and this central circular aperture has the central axis overlapped with the central axis 64 of rotor case 4 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 linked with the exit portion 158 of housing insert 72 for Purge gas.This flow path provided by recess 170 starts from its upstream extremity, have from the upper surface of frusto-conically shaped portion 156 to getting out of a predicament or an embarrassing situation 172.The sidewall 174,176 of recess 170 outwards develops from the center of housing insert 72 along with fluid path and increases height at downstream direction.If the top view of housing insert 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 insert 72.

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

Show the view of the separator 2 be fixed on turbine shroud 178 in fig. 2.Separator 2 is fixed on turbine shroud 178 by means of three threaded securing members 180, and each in securing member 180 passes and in lower end all-in-one-piece three lug bosses of rotor case 4.Only a securing member 180 and lug boss 182 is shown in the side cross-sectional view of Fig. 2.Those skilled in the art will understand from Fig. 2, support plate 70 (and, therefore all components of first group and second group) remain on the desired location relative to rotor case 4 by means of turbine shroud 178, support plate 70 to be depressed into when rotor case 4 and turbine shroud 178 are fastened to and go up each other and to adjoin with prone shoulder 148 by turbine shroud 178.Support plate 70 is clamped between rotor case 4 and turbine shroud 178 by means of threaded securing member 180 substantially.Because threaded securing member 180 is tightened, and it is adjacent that support plate 70 and shoulder 148 are occurred, so the second spiral 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 shroud 178, so that revolving wormgear impeller in the direction indicated by the arrow 134, as previously described with respect to FIG 1.The central axis 64 of this rotary actuation rotor assembly as a whole around rotor case 4 on the direction of arrow 134 of turbine wheel rotates.In other words, rotating shaft 78; Upper rotor part dish 80; Stacking 84 of separator disks 82; End plate 86; And the fan of combination and turbine unit 88 (that is, being jointly called rotor assembly in this article) to rotate relative to described housing 4 and support plate 70, housing insert 72 and turbine shroud 178 as the black box in rotary shell 4 together.

Release from engine crankshaft housing and need the gas processed by separator 2 to be introduced into separator 2 by the fluid intake 8 being positioned at the top of rotor case 4.As shown in by the arrow 68 in Fig. 8, inlet gas be parallel to central axis 64 and with the direction of central axis 64 conllinear on enter rotor case 4, and flow through three grooves 66 in top axle bearing unit 50 before flowing through six spokes 116 of upper rotor part dish 80.The rotary motion of six spokes also can cause the lateral 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 case 4.In fact, columniform 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, as shown in the arrow 184 in Fig. 8 towards the cylindrical wall of rotor case 4 via the space between adjacent separator disks 82.Joint filling part 100 gives lateral movement to being arranged in the fluid coiling stacking 84 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 case 4.This motion of the fluid caused by the rotation of dish stacking 84 is that fluid is drawn into the main mechanism adopted in separator 2.

It will be understood by those skilled in the art that oil droplet 186 tends to pool together and forms larger dripping at the periphery place of dish stacking 84.In this regard, the capillary force (Small Distance due between adjacent separator disks 82) acted on less oil droplet is tended 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 form larger the dripping with the quality (and " centrifugal " power be associated) being enough to overcome capillary force.Spontaneously throw afterwards on the cylindrical wall of rotor case 4.Once be received by described cylindrical wall, oil droplet 186 just tend to gravity and by the effect of the gas flow of separator 2 under advance to downwards in annular ditch 166.The most external circumferential edge of separator stacking 84 is inwardly spaced apart fully relative to the cylindrical wall of rotor case 4, to allow oil droplet not advance in described ditch 166 by the obstruction of separator disks 82 downwards.O-ring packing 160 guarantees that oil droplet flows into ditch 166, instead of between housing insert 72 and rotor case 4 (it has the possible consequence (as being easier to understand with reference to Fig. 1) polluting the clean gas flowing through the outlet 150 of housing insert 72).

The oil droplet 186 collected in ditch 166 is therefrom emitted by four discharge orifices 168.This discharge effect is assisted by the FPG in rotor case 4 and turbine shroud 178.More particularly, it will be understood by those skilled in the art that the rotary motion due to rotor assembly, the fluid pressure in rotor case 4 is larger in the peripheral edge place of separator disks stacking 84 is than the region between the downside of housing insert 72 and the upside of support plate 70.As a result, tend to there is the downward Purge gas stream by discharge orifice 168.This fluid stream tends to promote isolated oil droplet along annular ditch 166, and promotes it and pass downwardly through discharge orifice 168 and arrive on support 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 support plate 70 towards the central round orifice opening's edge in housing insert 72.This stream crossing support plate 70 tends to promote isolated oil droplet and crosses support plate 70 towards bottom bearing unit 90, and described oil droplet is through this 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 shroud 178.This contributes to again extracting oil droplet by bottom bearing unit 90.But, pump the major measure that oil droplet adopted by bottom bearing unit 90 to provide by deflecting packing ring 139, in use, this deflection packing ring 139 rotates relative to support plate 70 together with turbine unit, and from rotor case 4 pump oil, even if be also like this when the pressure in the pressure ratio rotor case in turbine shroud is larger.Then described outwards thrown in turbine shroud 178 by fan blade 140, and they can turn back to engine crankshaft housing from this turbine shroud 178.Meanwhile, the gaseous fluid flowing through support plate 70 is drawn upwardly the center port sent by package case 72, and leaves rotor case 4 by means of housing insert outlet 150 and rotor case outlet 10.

Also will understand with reference to accompanying drawing, 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.

To understand, by the oil stream of bottom bearing unit 90, there is on bearing unit useful lubricant effect.Top axle bearing unit 50 is similarly by naturally appearing at the oily mist lubrication being upwards sent to top axle bearing unit 50 in turbine shroud 178 and by the longitudinal flow path 92 of extend through rotating shaft 78.

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

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

The second, the layout of prior art separator makes Purge gas under certain conditions can become before leaving separator to be polluted.Therefore, can think relevant to undesirable oil pollution of the Equations of The Second Kind problem that prior art separator is associated and Purge gas.

3rd, some manufacturing technology be associated with prior art separator and architectural feature can cause assembling difficulty and/or integrity problem.Therefore, can think that the manufacture of the 3rd class problem be associated to prior art separator and separator is relevant with reliability.

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

About the fluid flow path by this separator 2, there are some positions, the higher pressure loss can be experienced in these positions.First, inlet/outlet pipe joint 22, the interior turning 40 of the elbow in 28 is too sharp-pointed to such an extent as to produce fluid from the separation the inner surface of pipe joint 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 energy/pressure loss again.But, described by above Fig. 4 about accompanying drawing, utilize injection-molded or die-casting technique manufactures inlet/outlet pipe joint time on interior turning, provide large radius to be problematic.As a result, prior art separator 2 experiences the pressure loss at pipe joint place when fluid enters rotor case 4 and under leaving valve cell housing 12 two kinds of situations.

Inventor has realized that six spokes 116 of upper rotor part dish 80 are other reasons of undesirable pressure loss.Specifically, will see especially from Fig. 5 and 6, spoke 116 has square-section separately, and they present sharp-pointed upper trailing edge (see Fig. 5) when the side of arrow 134 rotates up to the axial stream of the releasing gas entered at upper rotor part dish 80.Have been found that the sharp-pointed trailing edge 192 of the shape of spoke 116, particularly each spoke, fluid can be caused to be separated and undesirable pressure loss.

Inventor also finds that the specific structure of housing insert 72 can cause undesirable pressure loss.Specifically, during use separator 2, Purge gas is to be such as downward through the frusto-conically shaped portion 156 of housing insert 72 by the rotary motion around central 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 inner surface of the columniform sidewall of rotor case 4 with the pattern of spiraling.To understand, therefore, Purge gas is from the region (instead of a specific position enter described region) of the week along housing insert 72 between the peritropous end plate 86 entering a little frusto-conically shaped portion 156 and top.Therefore the flow path striding across frusto-conically shaped portion 156 has eddy flow pattern, and this pattern can cause undesirable pressure/energy loss.In addition, the step 172 and the wall 174,176 that are provided in the recess 170 in frusto-conically shaped portion 156 produce other flow separation zone, and the undesirable pressure loss be associated.

About the Equations of The Second Kind problem relevant with oil pollution, inventor 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.First, as described above, the stream passing downwardly through the Purge gas of rotor case 4 partly enters ditch 166 and tends to extract isolated oil droplet out by discharge orifice 168.If the flow rate of the air of purification is enough not high for the specified level of processed oil pollution, the oil droplet then collected in ditch 166 can climb up the ditch part 154 of housing insert 72, and then flows to (see Figure 10) on the frusto-conically shaped portion 156 of housing insert 72.Once oil droplet enters the region between frusto-conically shaped portion 156 and end plate 86, oil droplet just inevitably leaves separator 2 and removing pollutant gas.It may be the result allowing undesirably a large amount of oil to collect in the low flow rate of the Purge gas ditch 166 that oil droplet climbs from ditch 166.The Purge gas that existence upwards circulates in ditch 166 also can be tended to upwards extract oil droplet, and is drawn on the frusto-conically shaped portion 156 of housing insert 72.But, allow the climb notable feature of prior art separator 2 of emersion ditch 166 of oil droplet to be tubular outlet portion 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 droplet in ditch 166 defers to the circular path of 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 droplet will tend to defer to the path that arrow 196 (see Figure 12) indicates, and upwards flow through exit portion 158 and flow on the frusto-conically shaped portion 156 of housing insert 72.

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

The present inventor also finds, too much oil can be introduced into separator disks stacking 84 through the longitudinal flow path 92 of rotating shaft 78, indicated by the arrow 198 as shown in by Fig. 2.During normal operating condition, drive impeller described in the jet impulse of the oil of turbine wheel 136 and produce the mist of thin oil droplet.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 simultaneously also easily subsequently isolated from the gas flow entered by separator disks stacking 84.But in some cases, the amount transporting through the oil of rotating shaft 78 greatly to causing oil spill go out ditch 166 or otherwise flow on the frusto-conically shaped portion 156 of housing insert 72, and may flow into purified gas outlet 10 subsequently.This can such as occur when separator 2 tilts and the lower end of rotating shaft 78 is directly exposed to the oil storage remained in turbine shroud 178 surperficial.

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

First, about manufacture separator 2, inventor finds to use threaded securing member 32 to be fixed to by inlet/outlet pipe joint may be consuming time on rotor case 4 and valve cell housing 12, and need O-ring packing 36.

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

Relate between different components from the other problem that the assembling of separator 2 is associated, the interface such as between rotor case 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 the correct joint with new valve cell (or when will be other pipe-line system when not using valve cell).This can raise the cost and built-up time inadequately.In addition, asymmetric (by the causing for the moulded parts profile engaged with valve cell housing 12 of providing on described housing 4) of rotor case 4 tends to cause described housing 4 warpage during manufacture, and this tends to cause the problem unjustified relevant problem of component (such as, with) at assembly process.

The present inventor also recognizes, large O-ring packing 160 possible breakdown that housing insert 72 provides.More particularly, need O-ring packing against the major diameter face seal of two couplings, a surface provides on housing insert 72, and a surface provides on the cylindrical wall of rotor case 4.Rotor case 4 and housing insert 72 both have larger foozle, and this can cause O-ring packing 160 correctly can not seal two components.In addition, because two components use injection moulding technology to be manufactured by plastic material, each moulded parts moulded parts of rotor case 4 (and particularly) stands warpage after injection molding process.This can cause O-ring packing 160 correctly can not seal two components 4,72 in addition.To understand, if O-ring packing 160 fault, then isolated oil is by the region 200 that leaks between the skirt portions 152 of the external cylindrical of housing insert 72 and the cylindrical wall of rotor case 4.The oil leaked in this region 200 will finally enter the outlet 150 of housing insert 72 and removing pollutant gas.If O-ring packing 160 fault on the position of outlet 150, then isolated oil will tend to leak through O-ring packing 160 and directly enter outlet 150.Reduce warping effect (by increasing the cool time after injection molding process) when (i) takes measures, or when (ii) replaces leaker after product test, sealing problem can increase manufacturing time.

In addition, the moulded parts burr being arranged in the recess 159 receiving O-ring packing 160 can cause O-ring packing fault.

The present inventor also recognizes and the integrity problem for being associated with the layout of fixing angular orientation positioning separator dish 82 relative to rotating shaft 78.As above Fig. 7 about accompanying drawing set forth, prevent separator disks 82 from rotating relative to rotating shaft 78 by means of six keys (being fixed on rotating shaft 78) engaged with the hexagon 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 wearing and tearing of the interface between the hexagon aperture in key 122 and hub 120.These wearing and tearing can cause the significant relative rotary motion between separator disks 82 and rotating shaft 78.In fact, the present inventor has been found that adjacent separator disks 82 can relative to each other rotate and reaches joint filling part 100 and become unjustified degree, 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 Compress Spring 96 degree that upper rotor part hub 114 compresses.To understand, then compression stress no longer can be delivered to separator disks stacking 84 by end plate 86, and result, independent separator disks 82 can move up and down (and rotating relative to rotating shaft 78) along rotating shaft 78 freely vertically.This motion is very undesirable, and can reduce the separating property of separator disks stacking 84 significantly.

The other integrity problem that inventor recognizes relates to (i) rotating shaft 78 and top/bottom bearing unit 50, between 90; And

(ii) fretting wear of the interface between rotating shaft 78 and the first Compress Spring 96 is corroded.It will be understood by those skilled in the art that fretting wear is corroded when may have relative motion (such as, due to cooperation more loose between described component) between components to occur.Rotating shaft 78 extends through top and bottom bearing unit 50,90 and the first Compress Spring 96 with more loose cooperation.Axial prestrain is applied to top and bottom bearing unit 50,90 by the first and second Compress Springs 96,130 by this permission.Specifically, will understand from accompanying drawing, the first Compress Spring 96 pairs bottom bearing unit 90 applies axial force, and the second Compress Spring 130 pairs of top axle bearing units 130 apply axial force.Rotating shaft 78 allows the oscillating movement between these components with the loose fit of top/bottom bearing unit 50,90 and the first Compress Spring 96.This can cause again the fretting wear on described component to corrode.Relative motion between component also can allow hard particle to enter between described component, and this can accelerated wear test and cause integrity problem further.

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.

The separator of improvement understanding the present inventor's exploitation from accompanying drawing is immediately had the similar or identical component of many functions with prior art separator 2 performed by them and their ordinary construction aspect by those skilled in the art.Such component describes hereinafter by by the identical reference number used with use about prior art separator 2 above in the context of the separator improved.For example, referring to Figure 13 of accompanying drawing, technical staff will understand, and the separator 2 ' of improvement shown in this Fig comprises the rotor case 4 ' of general cylindrical, and it corresponds to the rotor case 4 of prior art separator 2 and performs similar function.Pass through accompanying drawing, 26S Proteasome Structure and Function difference between the component of such correspondence will be apparent for technical personnel, but when difference solve about prior art separator 2 or manufacture prior art separator 2 technique problem and provide relative to prior art separator 2 or manufacture the improvement of technique of prior art separator 2 time obvious time, substantially will discuss these differences in detail.

It will be understood by those skilled in the art that rotor case 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 be directed to described rotor case 4 '.As mentioned below, some in internals are positioned at rotor case 4 ', and other internals (such as, the fan of combination and turbine unit) be positioned at the outside of rotor case 4 ', however, be positioned in another housing (such as, turbine shroud).

The upper end of columniform 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 case 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 case 4 '.Exit aperture 10 ' extend through and therefore by columniform lug boss 202 around, this columniform lug boss 202 extends from the outer surface of rotor case 4 ' itself.

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

As from Figure 13 and 14 by apparent, and particularly from Figure 15 by apparent, the internals of valve cell 14 ' is integrally centered around in the housing 12 ' be separated with rotor case 4 '.More particularly, valve cell housing 12 ' comprises Part I 203 and Part II 205, and they are fitted to each other the enclosure space forming sealing, and the internals of valve cell 14 ' is arranged within this space.With reference to Figure 15, will see, the upper end of the Part I 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 case 4 '.

Also will see from Figure 15, the lower end of the Part I 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 case 4 ' via the exit aperture 10 ' in rotor case 4 '.O-ring packing 213 is positioned on the outer surface of columniform part 211, and adjoins against shoulder (limit on said surface), this shoulder in the separator 2 ' assembled towards the inside of rotor case 4 '.When assembly process promotes described part 211 by exit aperture 10 ', shoulder prevents O-ring packing 213 from moving along columniform the undesirable of part 211 thus, and O-ring packing 213 engages with described aperture 10 '.More particularly, O-ring packing 213 and the interior cylindrical of the lug boss 202 around exit aperture 10 ' face seal engage.

When O-ring packing 213 towards columniform part 211 root end (namely, one end of the columniform part adjacent with the remainder of valve cell housing) when providing, the second O-ring packing 215 is provided on the outer surface of free end (away from root end) of columniform part 211.Identical with when first O-ring packing 213, second O-ring packing 215 abuts against towards on the shoulder of the inside of rotor case 4 ', to prevent undesirable motion of the second O-ring packing 215 when described seal is pressed into final utilization position in the separator 2 ' assembled.More particularly, will understand from Figure 15, in the separator 2 ' assembled, the second O-ring packing 215 engages hermetically with the outlet 150 ' of housing insert 72 '.

Technical staff also will understand, and the first O-ring packing 213 prevents Purge gas and/or oil droplet from leaking between rotor case 4 ' and valve cell housing 12 ', and prevents them from undesirably leaking into environment from separator 2 ' thus.Technical staff also will be further understood that in addition, and the second O-ring packing 215 prevents oil droplet from leaking into the outlet 150 ' of housing insert 72 ' and polluting the Purge gas leaving rotor case 4 ' via columniform part 211 thus.Columniform part 211 and the first and second O-ring packings 213, the little external diameter (compared with the major diameter O-ring packing 160 of prior art separator 2) of 215 allows to use relatively little foozle, this error guarantees the less trouble about two O-ring packings 213,215.In this regard, will understand, such as, the warpage degree of the columniform part 211 of relatively little diameter will be less than the relatively large diameter rotor case 4 of prior art separator 2.

The lower end of the Part I 203 of valve cell housing 12 ' be provided be positioned at columniform part 211 side on the second lug boss 207.Identical with the situation of the first lug boss 207 provided on the upper end of Part I 203, the second lug boss 207 on the lower end of Part I 203 receives traditional threaded fastener 16 ', to be threadedly engaged (about described second lug boss 207,209 see Figure 18) with the second lug boss 209 that the lower end of rotor case 4 ' provides.

Because valve cell housing 12 ' is the housing be separated with rotor case 4 ', and geometrically independent with it (except mating and above and below lug boss 207 of columniform part 211 and exit aperture 10 ', outside the joint of 209 pairs), the rotor case 4 ' of the separator 2 ' of improvement has the overall shape of more closely similar cylindrical overall shape compared with the rotor case 4 of prior art separator 2.In this regard, notice that prior art rotor case 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 parts profile on side.But with reference to Figure 15, will see, the rotor case 4 ' of the separator 2 ' of improvement does not comprise aforementioned complexity and huge moulded parts profile.

Because rotor case 4 ' has the shape close with cylindrical shape, housing 4 ' can use injection moulding technology with during process for cooling compared with the housing 4 of prior art separator 2 the amount of warpage manufacture of minimizing form.This allows more easily to make top and bottom bearing unit 50 ', 90 ' align vertically.In addition, to understand, as long as the rotor case 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 columniform part 211 being applicable to mate with the exit aperture 10 ' of rotor case 4 ', and be applicable to mate with the lug boss 209 of rotor case 4 ' lug boss 207 of (valve cell housing 12 ' when) as shown in Figure 15.Such as, if alternative valve cell has with the columniform part identical with lug boss 207 with the columniform part 211 shown in Figure 15 with two lug bosses and with the housing of the relative positioning 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 with the inner valve of the valve cell 14 ' shown in accompanying drawing, accommodation arranges that diverse inner valve is arranged.This allows the modular structure of separator 2 ', and wherein parts have the versatility of increase between the difference of separator is arranged.

With reference to Figure 15, will see, the housing 12 ' of valve cell 14 ' is provided with the setting annular shoulder 18 ' defining fluid issuing, and by this fluid issuing, Purge gas spreads out of from separator 2 '.The annular shoulder 18 ' that valve cell housing 12 ' provides is substantially identical with the annular shoulder 6 ' provided on rotor case 4 '.Due to their similitude, entrance shoulder 6 and outlet shoulder 18 can receive the inlet/outlet pipe joint with identical interface profile interchangeably.The identical inlet/outlet pipe joint 22 ' with 90 ° of elbows is shown in Figure 13.Show inlet pipe joint 22 ' with cross section to mate with the shoulder 6 ' of rotor case 4 ', and other being shown as in fig. 17 is separated with described shoulder 6 '.

As the side cross-sectional view from Figure 16 being clear that, the inner surface of pipe joint 22 ' 216 and the curved surface of shoulder 6 ' combine to limit has 90 ° of elbows and the fluid flow path outside turning and interior turning significantly with radius.As a result, compared with the fluid stream at the sharp-pointed turning 40 arranged through prior art, the trend that fluid is separated from turning in elbow reduces more.Then also reduce the pressure loss.

Now with reference to rotor case shoulder 6 ' (it is identical with the shoulder 18 ' of valve cell housing 12 '), the interface between inlet/outlet pipe joint 22 ' and corresponding Housing shoulder 6 ', 18 ' is described in more detail.

As shown in figure 16 and 17, provide the setting shoulder 6 ' of rotor case 4 ' as annular relief, this annular relief has the general cylindrical wall 217 centered by the longitudinal axis overlapped with the central axis 64 ' of rotor case 4 '.The free end (distant place at the remainder of rotor case 4 ') of cylindrical wall 217 is provided with the circumferential antelabium 219 that formation extends inward into the curved surface 221 in the aperture formed by shoulder 6 '.In cross section (see Figure 16), curved 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 the longitudinal axis of cylindrical wall 217 and extends.In specific layout in figure 16, the swept arc 223 in part circular surface 221 ends at aforementioned radial 225 places.Also will understand from the side cross-sectional view of Figure 16, 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 top edge 229 of shoulder 6 '.

In addition, special in Figure 16, to understand, pipe joint 22 ' is provided with the profile mated with shoulder 6 ', makes the inner surface 216 of pipe joint 22 ' and the part circular surface 221 of shoulder 6 ' combine to provide and do not have convex ridge, shoulder, discontinuous and/or produce the smooth surface of any further feature of the pressure loss towards upstream/downstream.More particularly, the geometry of pipe joint 22 ' makes the transition part on the part circular surface 221 from the inner surface 216 of pipe joint 22 ' to shoulder 6 ' that obstruction or other pressure loss generation feature can not be utilized to provide the fluid stream on the surface (by the either direction of pipe joint 22 ') through combination.Given shoulder 6 ' is symmetrical, and no matter relative to the angle orientation of housing 4 ' or location, pole how, all keep is this situation to pipe joint 22 '.

Seamlessly transitting between the inner surface of pipe joint 22 ' and part circular surface 221 realizes in the following way in the layout of the separator 2 ' improved: the inner surface of pipe joint 22 ' is configured so that inner tube joint surface 216 is all oriented and is in the tangential of part circular surface 221 at inner tube joint surface 216 each some place with part circular surface 221 intersections.Therefore, about turning in the elbow be combined to form by pipe joint/shoulder, inner tube joint surface 216 and the preceding edge 229 place intersection of part circular surface 221 at shoulder 6 ', 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 to the outer corner of the elbow be combined to form by pipe joint/shoulder around shoulder 6 ', inner tube joint surface 216 radially moves inward through part circular surface 221 gradually with the point of part circular surface residing for 221 intersections of shoulder 6 '.Can see in Figure 16 that 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 will not necessarily all not have discontinuous or other pressure loss to produce feature on the whole.Especially, gap can be there is between the edge 231 of pipe joint 22 ' and the part circular surface 221 of shoulder 6 '.This gap in practice by utilize die-casting technique by steel (or other metal material) manufacture in pipe joint 22 ' and part circular surface 221 one or both and reduce.

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

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

As in prior art separator 2, the pipe joint 22 ' of the separator 2 ' of improvement uses traditional injection-molded or die-casting technique manufacture, and 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 pipe joint 22.But will understand, the interior section that the existence on the part circular surface 221 of Housing shoulder 6 ' combines the flow path elbow that the pipe joint 22 ' that improves ensure that housing 4 ' place provides radius.As the above mentioned, this and pipe joint 22 ' have nothing to do relative to the angular orientation of housing 4 '.Be separated from the fluid of the inner surface of elbow and reduced thus or avoid, and the pressure loss in this part of flow path is reduced similarly or avoided.

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

Again emphasize that rotary shell shoulder 6 ' is identical with the shoulder 18 ' on valve cell housing 12 ', and outlet pipe connection 22 ' be connected to this second Housing shoulder 18 ' about the described identical mode of rotor case shoulder 6 ' above.

From understanding above, pipe joint 22 ' can be positioned at as shown in Figure 16 shoulder 6 ' upper and adjacent with this shoulder 6 ' while do not rotate with being obstructed.Therefore, pipe joint 22 ' is rotatable to be welded on shoulder 6 ', pipe joint 22 ' is fixed to housing definitely with required angular orientation.It will be apparent to those skilled in the art that the method for stationary pipes joint 22 ' does not need to use threaded securing member as in prior art separator 2.Also will understand, this rotating welding technology allows pipe joint 22 ' to fix with any angular orientation relative to housing 4 ', and provides whole circumference (or closed loop) seal and do not need O-ring packing.Specifically, described melt surface is caused by acting on the heat that frictional force between the surfaces produces during the relative rotation of housing 4 ' (that is, shoulder 6 ') and the abutment surface of pipe joint 22 '.Then stop the rotation and the solidification of described surface, thus be bonded to each other.

Although above-mentioned rotating welding is the effective method be attached to by the material of pipe joint 22 ' on the material of housing 4 '; But also can use other method (such as, adhesive combines, ultra-sonic welded or Vibration Welding) in conjunction with described material.

With reference to Figure 34, aforementioned inner component is described special in more detail now.

First, top axle bearing unit 50 ' is fixed to the inner surface of rotor case 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 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 case 4 ' in the separator 2 ' assembled.Cylindrical wall 60 ' is from the upper inside surface of rotor case 4 ' to downward-extension.Circular convex ridge 238 also from the upper inside surface of rotor case 4 ' to downward-extension, and is positioned at the radially inner side of the first cylindrical wall 60 '.The cylindrical wall 60 ' of rotor case 4 ', circular convex ridge 238 and aforementioned shoulder 6 ' are located concentrically with respect to one another, and centered by the central axis 64 ' of rotor case 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 case 4 ' by means of rotating welding technology.Specifically, step parts 56 ' are welded on convex ridge 238.And use threaded securing member that top axle bearing unit 50 ' is fixed to rotor case 4 ' like that not as in prior art separator 2.This layout makes the rotation of top axle bearing unit 50 ' overlap with the central axis 64 ' of rotor case 4 '.

Three part circular grooves 66 ' (only show wherein two in Figure 34) are provided, to allow inlet fluid to flow through wherein (as shown in by arrow 68 ') in top axle bearing unit 50 '.Upper cap member 54 ' deflects the inlet fluid from 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 armature spindle during use.

Remaining internals of separator 2 ' assembles independent of rotor case 4 ', and then as a whole assembly be partly positioned removedly in housing 4 '.As about prior art separator 2, keep first group of fixing component relative to rotor case 4 ' when can think that this black box is included in use and in use around second group of component that central axis 64 ' rotates relative to rotor case 4 ' (and valve cell housing 12 ') and first group of component.

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

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

Second group of component forms rotor assembly, and comprise rotating shaft 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 guard dish 242 and combination and turbine unit 88 '.Rotating shaft 78 ' is made up of metal material, and the remainder of the aforementioned components of second group is made up of plastic material and is utilized injection moulding technology manufacture.The aforementioned components of second group is fixed in the mode being used for preventing or at least limit them relative to each other to rotate and goes up each other.Spiral compression spring (metal material) is additionally provided, as described in more detail below in second group of component.Second group of component is rotatably installed on first group of component by means of bottom bearing unit 90 ', and is rotatably installed on rotor case 4 ' by means of top axle bearing unit 50 ' in the separator 2 ' assembled.

The rotor assembly of second group of component formation will be described in more detail now.

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

Upper rotor part dish 80 ', separator disks 82 ', each in fan disk 240 and end plate 86 ' has the frusto-conically shaped portion (limiting upper and lower fi-ustoconical surface) being connected to and being positioned in use on rotating shaft 78 ' center hub element around.

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 be associated.These spoke parts have the space of opening between which, flow to allow fluid to pass axially through them along rotating shaft 78 '.

When fan disk 240, frusto-conically shaped portion 290 is connected to the center hub element 292 be associated by means of the second frusto-conically shaped portion 294.This second frusto-conically shaped portion 294 is continuous print, to provide obstruct to fluid, and thus anti-fluid along rotating shaft 78 ' or be upward through fan disk 240 or be passed down through fan disk 240 and flow vertically.

The Frusto-conical shape of the second frusto-conically shaped portion 294 has the angle larger 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 Frusto-conical shape of housing insert 72 ') situation (they all have identical angle) compare, the opposite side of the second frusto-conically shaped portion 294 is dispersed quickly/is assembled.Center hub element 292 is the cylindrical walls erect from the second 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 hub element 292, for receiving the key 254 radially extended from rotating shaft 78 '.By this way, prevent fan disk 240 relative to the rotation of rotating shaft 78 '.

The downside of the first frusto-conically shaped portion 290 of fan disk 240 is provided with the central axis equidistantly isolated multiple joint filling part parts 298 around fan disk 240.Each joint filling part parts 298 are provided as from the downside of the first frusto-conically shaped portion 290 straight convex ridge outstanding downwards, and extend to the edge, radially 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 guarantee the interval between fan disk 240 and end plate 86 ' thus, 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 case 4 '.Oil droplet (and/or, other liquid in fact entrained by gas flow or particulate pollutant) effectively dish out facing to the cylindrical wall 201 of rotary shell 4 ', and to dirty (or falling) on support plate 70 '.The gaseous fluid of discharging from the space between fan disk 240 and end plate 86 ' or also flow to downwards support plate 70 ' or directly and leave rotor case 4 ', as hereafter set forth in more detail.

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 is also from the described radial penetralia edge of frusto-conically shaped portion 108 ' to downward-extension.In the separator 2 ' assembled, cylindrical wall 300 centered by central axis 64 ', and along rotating shaft 78 ' fully to downward-extension, so that the center port that extend through provides in package case 72 '.Although described wall 300 has the shape of general cylindrical, the inner surface 302 of described wall 300 defines Frusto-conical shape, and the internal diameter of cylindrical wall 300 is reduced in an upward direction in the separator 2 ' assembled.The columniform outer surface of wall 300 has the diameter substantially identical with the center port of housing insert 72 ', and in the separator 2 ' assembled, is positioned in described aperture, makes there is minimum spacing between wall 300 and package case 72 '.This closely cooperates, and while allowing the relative rotation between end plate 86 ' and package case 72 ', contributing to minimizing can flow so that the amount of the isolated oil of removing pollutant gas between described wall 300 and the center port of package case 72 '.In addition, the Inner frustoconical shape surface 302 of described wall 300 works to resist in the space that the oil droplet upwards flowed is sent between fan disk 240 and end plate 86 '.It will be understood by those skilled in the art that the oil droplet of fi-ustoconical surface of contact wall 300 will stand rotary motion, and due to the Frusto-conical shape on described surface, stand the power acted on downwards.

Splash guard dish 242 comprises the annular disk 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 rotating shaft 78 ' in the separator 2 ' assembled (sees Figure 28) especially.The diameter of the center port limited by the annular disk 304 of plane equals the internal diameter of the lower end of the cylindrical wall 300 of end plate 86 ' substantially.There is not significant pressure loss generation feature in the junction surface place of fluid stream therefore between splash guard dish 242 and end plate 86 ' entering the region fan disk 240 and end plate 86 ' through splash guard dish 242.To understand, annular disk 304 provides vibrating part, this vibrating part extends from the lower end edge of described cylindrical wall 300 radial direction, and any spacing between the part of center port that extends through of the described wall of restriction 300 working the outer surface and housing insert 72 ' covering described cylindrical wall 300 in use.By this way, the annular disk 304 of plane reduces isolated oil droplet and spatters or otherwise to move up and through the center port of package case 72 ' so that the possibility of removing pollutant gas from support plate 70 '.

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

The hub element 308 of splash guard dish 242 provides as cylinder, and its upper end is closed by the wall be arranged to perpendicular to the plane of described cylindrical longitudinal axis (and, in the separator 2 ' assembled, perpendicular to central axis 64 ').Described cylindrical internal diameter is larger than the external diameter of rotating shaft 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 cylinder of rotating shaft 78 ' and hub element 308 limits annular space between which, this annular space receives spiral compression spring 96 ', adjoin splash guard 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 those skilled in the art that splash guard dish 242 and end plate 86 ' separate manufacture, to allow the cylindrical wall 300 of end plate 86 ' to locate through the center port of package case 72 '.If splash guard dish 242 and end plate 86 ' are one, then this will be impossible, because the external diameter of annular disk 304 is larger than the diameter of the center port in housing insert 72 '.

As mentioned above, upper rotor part dish 80 ', fan disk 240 (about its first frusto-conically shaped portion) and the Frusto-conical geometry of end plate 86 ' are substantially identical with the geometry of separator disks 82 '.This allows upper rotor part dish 80 ', fan disk 240 stacking together with separator disks 82 ' with end plate 86 ', 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 technical staff will understand separator disks 82 ' will be thinner, to allow the dish providing larger amt in relatively short stacking 84 ', but upper rotor part dish 80 ' is much thicker than separator disks 82 ' with end plate 86 ', to provide rigidity at the two ends place of dish stacking 84 ', and allow thus, by means of upper dish 80 ' and end plate 86 ', compression axial force is applied to the frusto-conically shaped portion of separator disks 82 ' equably.To understand, compression stress is produced by described spiral compression spring 96 ', and spiral compression spring 96 ' is upwards pressed on the downside of hub 308 of splash guard dish 242.Then the hub 308 of splashproof 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 ', technical staff will understand, 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 distance piece 246.Each distance piece 246 is that the upper surface 102 ' of the frusto-conically shaped portion 124 ' being positioned at each separator disks 82 ' is upper and from its outstanding point (see Figure 20).

Nethermost separator disks 82 ' in stacking 84 ' can be also spaced apart with fan disk 240 alternatively, to allow fluid to flow between which.If need this interval, then use suitable distance piece.Ideally, the upper surface of first frusto-conically shaped portion (below its frusto-conically shaped portion being positioned at dish stacking 84 ' and the second frusto-conically shaped portion by means of fan disk 240 is connected to fan hub) of fan disk 240 is provided with distance piece 246 in the mode identical with the frusto-conically shaped portion of each separator disks 82 '.

Each in described distance piece 246 has round-shaped, but can use other shape (such as, can use elliptical shape).Any alternative shape for distance piece 246 preferably has bending edge, to reduce the fluid pressure loss flow through in the fluid of distance piece.

First group of distance piece 246 is arranged in the circle concentric and adjacent with the inside circular edge 104 ' of described upper surface 102 '.Each distance piece 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 '.Second group of distance piece 246 is arranged in concentric and in the circle be adjacent with the outer circular edge 106 ' of described upper surface 102 '.3rd group of distance piece 246 be arranged in the inner circular edge 104 ' of the frusto-conically shaped portion coiling 82 ' and outer circular edge 106 ' concentric and in the circle of about centre between which.

As set forth in more detail hereinafter, each separator disks 82 ' (and, in fact, fan disk 240) can be positioned on rotating shaft 78 ' relative in rotating shaft 78 ' only three feasible Angle Position, and the location of distance piece 246 on described upper surface 102 ' makes the distance piece 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 ' to be shifted onto rotating shaft 78 ' and is upper and push it to adjacent to each other to form aforementioned stacking 84 ' time, necessary: each distance piece 246 that (i) specifically coils 82 ' is located in stacking 84 ' directly over the distance piece 246 of the adjacent dish 82 ' being positioned at described specific dish 82 ' below, and each distance piece 246 that (ii) specifically coils 82 ' is located in stacking 84 ' immediately below the distance piece 246 of the adjacent dish 82 ' being positioned at described specific dish 82 ' top.As a result, the distance piece 246 be applied to by end plate 86 ' by means of alignment in the inc situation in interval of compression stress between adjacent separator disks 82 of dish stacking 84 ' passes through stacking 84 '.This guarantees that fluid keeps to flow between separator disks 82 '.

To understand, with reference to the accompanying drawings, distance piece 246 has little radial dimension and little circumferential size for the size (diameter) of the separator disks be associated.This allows fluid circumferentially to flow through described dish upper surface 102 ' in direction in the mode relatively do not hindered by distance piece, and radially flows through described surperficial 102 '.This guarantees the minimise loss of pressure in the fluid stream between adjacent dish 82 '.

Other component showing upper rotor part dish 80 ' and rotating shaft 78 ' and separator 2 ' in Figure 21 and 23 of accompanying drawing is isolated.The hub 114 ' of upper rotor part dish 80 ' is molded on the outer surface of rotating shaft 78 ', and is attached to thus on described axle 78 '.This combination prevents the relative rotation between hub 114 ' and rotating shaft 78 '.

The hub 114 ' of upper rotor part dish 80 ' upwards extends vertically along rotating shaft 78 ', and ends at the upper end of described axle 78 '.The upper part (the second spiral compression spring 130 ' is positioned at around it) of rotating shaft 78 ' is provided with the coating (lining) of plastic material (preferred thermoplastic) thus.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 second group of internals show in Figure 19.Except the plastic coating that the upper end part of wherein rotating shaft 78 ' is adjacent with the second helical spring 130 ', alternative separator is identical with the first embodiment.

The hub 114 ' of upper rotor part dish 80 ' also along rotating shaft 78 ' vertically to downward-extension, and ends at the some place directly over bottom bearing unit 90 '.Bottom bearing unit 90 ' contacts the metal end of rotating shaft 78 ' thus in the separator 2 ' assembled.More particularly, hub 114 ' extends along the entire depth of separator disks stacking 84 ', and makes the hub 120 ' of each separator disks 82 ' be separated with rotating shaft 78 ' thus.Also will understand, hub 114 ' is also the coating (lining) that rotating shaft 78 ' provides plastic material (preferred thermoplastic) in the region of the first spiral 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 ' are from described edge 312 vertically to downward-extension.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 the cylindrical wall in frusto-conically shaped portion 112 ' below and through dish stacking 84 ' towards rotor case 4 ' is outwards dished out effectively.Spoke parts 116 ' can cause upper rotating disc 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 case 4 ', described space 600 represents the entrance of rotor assembly thus.

Enter the fluid of rotor case 4 ' through 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 immediately below three part circular grooves 66 '.Special Figure 34 with reference to accompanying drawing, to see, the radial dimension of part circular groove 66 ' is less than the radial dimension of spoke parts 116 ' (namely, length), as a result, a very large part for the fluid entered only impacts the length be positioned at immediately below 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 with inlet fluid from spoke parts 116 ' pressure loss be associated.This realizes in the following way: be provided to by the basic axial stream of inlet fluid and have in the rotor case 4 ' of stator, 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 fluid stream 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.The surface of stator 314 works to guide the fluid of the leading edge 310 close to spoke element 116 ' to align with spoke element 116 '.The string 316 be 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-phase is represented by arrow 320 for the direction of stator 314, and indicated by Figure 22, will be interpreted as be (i) inlet fluid flow (amount) (Q/A, wherein, Q is the volume fluid flow rate by entrance; And A is the area of section of inlet flow paths) axial velocity, and the tangential velocity of (ii) stator 314 (wherein, ω is upper rotor part dish is angular speed to ω r; And r is stator apart from the radial distance of pivot) function.Because fluid stream depends on the radial position r along stator 314 relative to the direction 320 of stator 314, string 316 can be oriented to the angle along with radial position changes.In other words, fluid stator 314 can be provided with torsion, to guarantee stator 314 and the fluid stream entered correctly aliging in all radial positions place along stator 314.More particularly, the acute angle 322 between string 316 and vertical datum line 324 (parallel with the central axis 64 ' in the separator 2 ' assembled) can increase towards most external radial position along spoke parts 116 ' gradually from penetralia radial position.

Technical staff will understand, using the separator 2 ' period of improving, the air entered is downward through three part circular grooves 66 ' vertically, and impacts and be arranged in described groove 66 ' below short distance and on the stator 314 rotated at circular path around central axis 64 '.Because the string 316 of the leading edge 318 of each stator 314 is oriented the angle of attack relative to the fluid stream entered with basic zero degree, both the low-pressure side 324 that described fluid flows through stator 314 and high-pressure side 326, and directed and flow on the axial direction relative to spoke parts 116 ', and can not be separated from stator 314 or the spoke be associated parts 116 '.The pressure loss produced by the fluid flowing through upper rotor part dish 80 ' is avoided thus or is minimized.

The other result of the reduction of the pressure loss that stator 314 provides is that the quantity of spoke parts 116 ' can increase (compared with prior art separator 2) and the fluid stream flow rate as a whole that can desirably affect by separator 2 '.The spoke parts 116 ' increasing quantity allow larger compression stress 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 '.

To notice, 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 be in fact particularly preferred rotary speed and fluid flow rate.

With reference to Figure 21, will see columniform 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 between them from leaking (seeing Figure 34 especially) 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 are equidistantly spaced apart around the central longitudinal axis of upper rotor part dish 80 ', and the following point extended to vertically along hub 114 ' (and therefore along rotating shaft 78 ') from the downside 330 of spoke parts 116 ' along hub 114 ': the separator 2 ' assembled, this center hub element 292 along fan disk 240 is approximately positioned at centre.

Each key 254 has root portion 350 and tip portion 352.Root portion 350 links with the remainder 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 is wider than tip portion 352 (that is, having larger circumferential size).Due to the different in width of root portion 350 and tip portion 352, the both sides that the junction surface between root portion 350 and tip portion 352 is in each key 254 provide step 354.Special in Figure 23, will see, the width of the root portion 350 of each key 254 upper end from the lower end of each key 254 to each key 254 increases.In addition, the width of each root portion 350 is no better than 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 adjoins with it.

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

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 remainder of the separator disks 82 ' be 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 resist side direction and revolving force that they stand and can not be out of shape, and the compression stress produced by helical spring 96 ' passes through separator disks stacking 84 ' via distance piece 246 by separator plate convergence 126.

Technical staff also will understand, and as previously discussed, the key 252 of each separator disks 82 ' and the relative geometry in aperture 252 ensure that each separator disks 82 ' can in only three Angle Position be positioned on rotating shaft 78 '.By means of the location of distance piece 246 relative to aperture 252, the pole of the distance piece 246 of separator disks 82 ' or location, angle keep identical relative to rotating shaft 78 ', no matter and use in three Angle Position which, and therefore, do not exist the distance piece 246 of adjacent separator disks 82 ' unjustified time separator disks stacking 84 ' be assembled in possibility on rotating shaft 78 '.However, each separator disks 82 ' is provided with and can coils the mark of the label alignment of 82 ' with other in dish stacking 84 '.By this way, all dishes 82 ' in stacking 84 ' will have identical Angle Position relative to rotating shaft 78 '.Mark provides as to be positioned between two spokes 126 ' on hub and to 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 rotating shaft 78 ' is provided on the upper surface of upper rotor part hub 211 '.Annular recess 258 receives the second spiral compression spring 130 ' and prevents this spring 130 ' along the downward axially-movable of rotating shaft 78 '.In addition, in the separator 2 ' assembled, the cage of cage bearing 52 ' adjoins and compresses the second spring 130 ' (wherein the upper end maintenance of rotating shaft 78 ' and cap member 54 ' the Jian Ge Kai – of top axle bearing unit 50 ' are shown in Figure 34 especially) downwards.

In the separator 2 ' period that assembling improves, be all connected to each other mutually except the fan of combination and turbine unit 88 ' in second group of internals.Together with upper rotor part hub 114 ' (and remainder of upper rotor part dish 80 ') and rotating shaft 78 ' are injection-molded in position.Stacking 84 ' of separator disks 82 ' then slides axially along rotating shaft 78 ' from its lower end edge, to be positioned to adjoin with the downside of the frusto-conically shaped portion 112 ' of upper rotor part dish 80 '.

Be installed to the lower end of rotating shaft 78 at fan/turbine unit 88 before, the lower end of axle 78 is positioned through the central circular aperture provided in support plate 70 in first group of internals and each in housing insert 72.Like this, the lower end of rotating shaft 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 support plate 70.

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

Due to the rigidity of end plate 86 ', compression stress is delivered to the frusto-conically shaped portion 108 ' of end plate 86 ' by described multiple spoke parts 110 ' radially extended from hub 98 '.Then compression stress 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 distance piece 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 '.Compression stress is delivered to the hub 114 ' of upper rotor part dish 80 ' via 12 spokes radially extended 116 ' from frusto-conically shaped portion 112 '.Compression stress 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 ' reacts on compression stress and is upwards prevented by the position of the upper rotor part hub 114 ' adjacent with the prone shoulder 250 on rotating shaft 78 ' along the axially-movable of rotating shaft 78 '.Upper rotor part dish 80 ' is prevented along the axially-movable of rotating shaft 78 ' by the position with the upper rotor part hub 114 ' adjacent towards upper annular shoulder 248 on rotating shaft 78 ' downwards.

The adjacent dish 82 ' coiling stacking 84 ' can be fixed to alternatively definitely to be gone up each other.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 (that is, guaranteeing that dish distance piece 246 keeps alignment, to transmit compression stress and space between adjacent dish 82 ' can not close).Dish 82 ' is fixed on by welding (such as, ultra-sonic welded) and goes up each other.

In prior art separator 2 ', be installed to the lower end of rotating shaft 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 support plate 70 ' and housing insert 72 ' of first group of internals.The lower end of rotating shaft 78 ' also extends through the bottom bearing unit 90 ' (seeing Figure 29 and 30 especially) of the center port being fixed to support plate 70 '.

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

Back-up ring 132 ' and Compress Spring 360 are positioned at the fan of combination and the cavity of turbine unit 88 '.Compress Spring 360 upwards compresses in described cavity, upwards fan/turbine unit 88 is 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, will understand, and 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 be separated.The radial inner portion of deflector surface 139 ' is upwards pressed onto to be adjoined with the inner race of bottom bearing unit 90 ', and this inner race is upwards pressed against on support plate 70 ' again.The radially outer bearing race of deflector surface 139 ' and bottom bearing unit 90 ' is spaced apart from each other, vertically to allow isolated oil to be downward through bottom bearing unit 90 ' and flow radially outwardly through described axially spaced-apart and enter turbine shroud.

The rotor assembly of separator 2 is rotating (see Figure 29 and 30) by means of hydraulic impulse turbine by arrow 134 ' indicated direction.As in prior art separator 2 ', fan/turbine unit 88 ' comprises the Pelton impeller 136 ' with the multiple wheel blades 138 ' be evenly spaced apart along its periphery.When using separator 2 ', the jet of oil is from the nozzle (not shown) guiding in turbine shroud to the periphery of Pelton impeller 136 '.More particularly, jet, along the tangential guiding of the circle through multiple wheel blade 138 ', makes jet enter the wheel blade with its surface in alignment.Jet flows along the described surface of the in-profile deferring to wheel blade, and is rotated by described profile afterwards, to flow along other surface, 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 support 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 rotating shaft 78 '.Fan blade 140 ' extends radially outward near bottom bearing unit 90 '.It will be understood by those skilled in the art that fan blade 140 ' rotates around central axis 64 ' when turbine wheel 136 ' rotates.Like this, fluid is dished out from the region between impeller 136 ' and the downside of support plate 70 ' by fan blade 140 ' effectively, thus the fluid pressure reduced in the region of bottom bearing unit 90 ', and contribute to isolated oil to pump by bottom bearing unit and the turbine shroud pumping to support plate 70 ' below from the position of support plate 70 ' top downwards.

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

The plurality of fan blade 140 ' and deflector surface 139 ' form with the upper part 142 ' of fan/turbine unit 88 '.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 perpendicular to central axis 64 ' and strides across the plane to the unlimited lower opening of the flow path 92 ' of rotating shaft 78 '.However, plate member 364 is opened, to allow fluid to flow into described opening with the described open space leading to flow path 92 '.

Plate member 364 is provided with four apertures 366, and aperture 366 is equidistantly located along the imaginary circles centered by central axis 64 ' in the separator 2 ' assembled.It will be understood by those skilled 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 flow path 92 '.To understand, therefore, this layout makes the mist of oil droplet upwards to flow through aperture 366 from turbine shroud and to enter the cavity in fan/turbine unit 88 ' thus, and upwards flows through the flow path 92 ' of rotating shaft 78 '.But, also by understanding being flowing in radially inside direction from aperture 366 to the described opening of flow path 92.In use separator 2 ' period, fan/turbine unit 88 ' rotates certainly in arrow 134 ' indicated direction, and the mist of oil droplet radially inwardly can flow to flow path 92 ' from aperture 366 simultaneously, the oil flowing through the ratio in aperture 366 relatively large laterally moves by the plate member 364 spinned in direction, and tends to be dished out by the outward opening away from flow path 92 '.Such as, at inclination of vehicle or in addition to make upwards to spill oil by aperture 366 so that the mode pouring the cavity of fan/turbine 88 ' moves from turbine shroud, the lateral movement of giving for the oil in described cavity is tended to prevent the inwardly rotating shaft 78 ' flowing of described oil.Therefore avoid a large amount of oil undesirably upwards flow through rotating shaft 78 ' and enter dish stacking 84 '.

Two discharge orifice 368 are provided, to allow oil to get back to turbine shroud from the cavity discharge in fan/turbine unit 88 ' in plate member 364.Discharge orifice 368 is positioned to diametrically toward 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 guarantees really effectively to discharge from fan/turbine unit 88 ' away from the dish out oil of neighboring of described cavity of rotating shaft 78 '.

Although showing plate member 364 with the low portion 144 ' of 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 be separated with the low portion 144 of fan/turbine unit 88 '.With reference to Figure 31 and 32, will see, the plate member 364 of the separation of alternative is the circular discs being provided with aperture 366 in the mode identical with Figure 29 and 30.But alternative plate member 364 is in position relative to the remainder of fan/turbine unit 88 ' by threaded fastener 362 (extending through them), and does not have discharge orifice 368.In this alternative arrangement, only in the cylindrical wall of low portion 144 ', provide discharge orifice 368, 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 second cylindrical wall 370 in addition, second cylindrical wall 370 is positioned at the cavity of fan/turbine unit 88 ' and to downward-extension to provide prone annular surface, can faces toward this annular surface pressing plate component 364 by two threaded fasteners 362.Recess is provided, to provide fluid path 372 between described cylindrical wall 370 and plate member 364 in prone annular surface.In use, the oil flowing outwardly through the upper surface of plate member 364 is sent to discharge orifice 368 via flow path 372.

Although the fan/turbine unit 88 ' of Figure 31 and 32 is provided with the outer cylindrical wall and plate member 364 that together define cavity, and be also 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 be fixed to rotating shaft 78 ' in the mode identical with prior art separator 2.Specifically, fan/turbine unit 88 ' is fixed to rotating shaft 78 ' by means of packing ring 133 ', and packing ring 133 ' is upwards pressed in the upper and back-up ring 132 by means of the peripheral recess be arranged on the outer surface of rotating shaft 78 ' of the low portion 144 ' of described unit 88 ' and is held in place.To understand, packing ring 133 ' and back-up ring 132 provide alternative fixing means for the Compress Spring 360 shown in Figure 29 and 30 and back-up ring 132.

About first group of internals, support plate 70 ' has round-shaped, and this is round-shaped has the diameter substantially equal with the diameter of rotor case 4 '.As in prior art separator 2 ', relative geometry so to such an extent as to allow support plate 70 ' to be positioned on prone shoulder 148 ' at the lower end of rotor case 4 '.By this way, the lower open end of rotor case 4 ' is closed by support plate 70 '.But in the separator 2 ' improved, the lower open end of rotor case 4 ' adjoins the upside of support plate 70 ' and is provided with peripheral recess 260, and this peripheral recess 260 is for receiving O-ring packing 262 (see Figure 34).To understand, the second O-ring packing 262 ensure that the Fluid Sealing between rotor case 4 ' and support plate 70 '.

In addition, in the separator 2 ' assembled, circumferential edge surface, radially portion 630 (formation datum level) registration of support plate 70 ' becomes adjacent with the columniform inner surface 632 around the lower open end of rotor case 4 '.By this way, support plate 70 ' is laterally aligned in the final position (see Figure 13) of expectation relative to rotor case 4 '.

Support plate 70 ' is also provided with central circular aperture, and in the separator 2 ' assembled, central circular aperture is concentric with rotor case 4 '.In other words, in the separator 2 ' assembled, the circular central aperture of support plate 70 ' is centered by the central axis 64 ' of rotor case 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 support plate 70 '.The radially portion part of bottom bearing unit 90 ' is fixed relative to support plate 70 '.The radial penetralia part of bottom bearing unit 90 is positioned near rotating shaft 78 ', but not fixed thereon.

As previously discussed, first group of internals also comprises the housing insert 72 ' be fixed to definitely on support plate 70 '.As in prior art separator 2 ', housing insert 72 ' work to make Purge gas with therefrom isolated oil isolate.The housing insert 72 ' of the separator 2 ' improved additionally provides the outlet 150 ' for Purge gas, and this outlet 150 ' is directly connected hermetically with the columniform intake section 211 (see Figure 15) of valve cell housing 12 '.

Housing insert 72 ' provides as the moulded parts of the one of plastic material.But, when following description housing insert 72 ', will think that plug-in unit comprises four parts: the outside deflector wall 264 with Frusto-conical shape; There is the abutment wall 266 of columniform shape; There are the isolating roof parts 268 of Frusto-conical shape; 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 insert 72 ' have Frusto-conical shape 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 central axis overlapped with the central axis 64 ' of rotor case 4 '.Elongated channel/recess 272 (see Figure 28) is provided in the upper surface of isolating roof parts 268.This path/recess 272 defines the fluid path for Purge gas, and it extends to the exit portion 270 (having tubular form) of housing insert 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 be positioned to the exit portion 270 of housing insert 72 ' substantially diametrically.The arc 280 of about 80 ° of the aforementioned recessed part extend through of described periphery edge 274, this arc is centered by the described central axis in housing insert aperture.In an alternative embodiment, the recessed part of the arc (such as between 45 ° and 110 °) that the entrance of fluid path can be different by the extend through in described periphery edge 274 limits.In the separator 2 ' assembled, only little distance separates isolating roof parts 268 and end plate 86 '.Result, think 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 flows into described region through the remainder of described periphery edge 274.

To understand, therefore the space between whole circumferential 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 larger degree of depth 613 (namely than the part of other length direction of entrance 610, larger axial spacing between periphery edge 274 and end plate 86 '), so most flowing into the Purge gas in described region 606 is done like this by the described part 612 with the length direction of the larger degree of depth 613.The degree of depth of the part of remaining length direction of described area entry (610) is minimum, to minimize the fluid stream through them, and also minimizes oil droplet passing through through them thus.The degree of depth of the part of remaining length direction can between 1/10th and half of the larger degree of depth 613, but 1/3rd of the degree of depth 613 larger described in being preferably.

In use separator 2 ' period, the Purge gas leaving separator disks stacking 84 ' flows downward with the inner surface of the rotary motion of spiraling along the cylindrical wall of rotor case 4 '.To understand, 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 centered by the central axis 64 ' of rotor case 4 ' to move and is done like this.But the gas flow 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 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.In this regard, to see from Figure 28 of accompanying drawing, the upstream portion of elongated recesses 272 is bending (sidewalls 276 of recess 272,278 align with the inlet fluid of eddy flow thus, to initial assault sidewall 276 at fluid, minimize desirable going when 278 significantly and press (unpressure) loss) and straighten gradually when flow downstream exports 150 ' movement along recess 272 towards plug-in unit.Think compared with above-described prior art separator 2, the pressure loss that the minimizing immediately entering the swirling motion in the major part of the clean gas in the region between isolating roof parts 268 and end plate 86 ' can reduce in the fluid of this part flowing through separator 2 ' significantly.

To understand, do not flow through entrance 282 but the Purge gas 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 received by elongated recesses 272, after this, think that particularly radially outer sidewall 276 will guide fluid towards plug-in unit outlet 150 ', and reduce the swirling motion of described fluid.

Columniform 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, the adjacent support plate 70 ' (junction surface place between which) of prone lower circular edge 450 (see Figure 27) of abutment wall 266.Isolating roof parts 268 are bearing on support plate 70 ' by abutment wall 266 thus, and guarantee the correct axial location of isolating roof parts 268 relative to support plate 70 '.Abutment wall 266 is also provided with multiple columniform lug boss 452, and they have the recess for receiving securing member 74 ' threadably separately.In the separator 2 ' assembled, each securing member 74 ' to be extended to from the below of support plate 70 ' by the aperture support plate 70 ' in described lug boss 452.By this way, package case 72 ' is fixed on support plate 70 ' definitely.

The prone lower circular edge 450 of abutment wall 266 is 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 support plate 70 ', and using the separator 2 ' period assembled, fluid can flow through this space.Specifically, in use separator 2 ' period, the isolated oil radially inwardly flowed from the cylindrical wall of rotor case 4 ' along support plate 70 ' is through multiple recess 454.A part for Purge gas also radially inwardly flows through the upper surface (technical staff will understand) of support plate 70 ', and this fluid also flows through multiple recess 454.This fluid stream is indicated by the arrow 188 ' in Figure 34.

Outside deflector wall 264 is from the periphery edge 274 of isolating roof parts 268 to downward-extension.Deflector wall 264 has in the separator 2 ' assembled along the Frusto-conical shape of in downward direction dispersing from isolating roof parts 268 towards support plate 70 '.The diameter (and therefore, the diameter of the periphery edge 274 of isolating roof parts 268) that deflector wall 264 is located at its upper end equals the external diameter of separator disks stacking 84 ' substantially.Due to the Frusto-conical shape of deflector wall 264, when edge is in downward direction moved, deflector wall 264 is assembled about the general cylindrical wall of rotor case 4 '.The sectional area of the flow path between deflector wall 264 and rotor case 4 ' therefore in the flowing direction (that is, in a downward direction) reduce.The lower free end 608 of deflector wall 264 is positioned to the cylindrical wall of rotor case 4 ' spaced apart, and between spaced apart 2 millimeters and 200 millimeters of support plate 70 ' top and the preferred distance 456 of 14 millimeters.This interval of outside deflector wall 264 and rotor case 4 ' and support plate 70 ' allows isolated oil (or other material be separated) and Purge gas (it does not enter first area entrance 610) to flow downward along the cylindrical wall of rotor case 4 ', and radially inwardly flows through deflector wall 264 (comprising its free end) along support plate 70 '.Like this, isolated oil and Purge gas flow through the second area 614 on the side contrary with the first flow region 606 of housing insert 72 '.

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

More particularly, although the relatively large spacing between the upper end of rotor case 4 ' and deflector wall 264 allows isolated oil easily to enter between these features, the smaller spacing of the lower free end in deflector wall 264 between these features can reduce isolated oil can upwards be splashed into or be recycled to easiness between described free end and rotor case 4 '.In addition, any recirculation of the fluid near the radial outer periphery of support plate 70 ' will be tended to cause isolated oil to flow into abovementioned cavity 458.Such as, isolated oil upwards can flow along the radially-outer surface of columniform abutment wall 266, along isolating roof parts 268 downside outwardly, and then to flow downward along the inner radial surface of deflector wall 264.In due course, oil may be fallen support plate 70 ' from cavity 458 under gravity.To understand, this recirculation flow path can not cause isolated oil upwards to flow in the mode of the risk causing the Purge gas polluting the region flowed between isolating roof parts 268 and end plate 86 '.Therefore, once (namely Purge gas flows through region 606 entrance towards support plate 70 ', lead to the entrance between isolating roof parts 268 and end plate 86 '), the any recirculation subsequently just preventing described gas upstream to return towards described entrance causes the gas (and the oil droplet carried by it) recycled 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 insert 72 ' is provided as columniform tube element, this columniform tube element opens wide (and more specifically to the upper surface of isolating roof parts 268, open wide to the recess 272 for receiving Purge gas), and extend through abutment wall 266 and outside deflector wall 264 in cardinal principle direction radially.As the Figure 13 and 14 from accompanying drawing will be obvious especially, exit portion 270 is positioned on the prone edge of abutment wall 266.Therefore, in the separator 2 ' assembled, exit portion 270 is positioned at support plate 70 ' top, makes fluid can at exit portion 270 flowing underneath.Advantageously, isolated oil can at exit portion 270 flowing underneath, and therefore, be not inclined to and climb on the outer surface of exit portion 270 towards the periphery edge 274 of isolating roof parts 268, herein, isolated oil easily can pollute the clean gas of the recess 272 flowing into housing insert 72 '.Exit portion 270 at it, to one end that recess 272 opens wide, free end is at a distance provided with supporting member 460, supporting member 460 is outstanding downwards from the bottom part of described free end, so that adjacent support plate 70 '.By this way, supporting member 460 to contribute between support plate 70 ' and exit portion 270 minimally spacing, but also allows the free end of support plate 70 ' to exit portion 270 to provide supporting.

At assembly process, separator 2 ' be fixed to turbine shroud (not shown) about the similar mode described by prior art separator 2 ' above.Specifically, the separator 2 ' improved is fixed to turbine shroud by means of four threaded securing member (not shown)s, and each threaded securing member passes and the different lug boss (seeing Figure 18 and 29 especially) in lower end all-in-one-piece four lug bosses 284 of rotor case 4.

It will be appreciated by those skilled in the art that, as when prior art separator 2, support plate 70 ' (and therefore, all components in first group of component and second group of component) to remain by means of turbine shroud and be in desired location relative to rotor case 4 ', after rotor case 4 ' and turbine shroud are fastened to and go up each other, support plate 70 ' is depressed into prone shoulder 148 ' adjacent by this turbine shroud.Support plate 70 ' substantially by means of the threaded fastener clamp of extend through four lug bosses 284 between rotor case 4 ' and turbine shroud 178 '.Be tightened along with threaded securing member and make support plate 70 ' and shoulder 148 ' occur to adjoin, result, the O-ring packing 262 at described shoulder 148 ' place is pressed in the recess 260 be associated, and the second spiral compression spring 130 ' is compressed by top axle bearing unit 50 '.

Improve separator 2 ' operation in, the jet of oil is directed on turbine wheel 136 ' by the nozzle (not shown) in turbine shroud, so as in arrow 134 ' (see Figure 29 and 34) indicated direction revolving wormgear impeller.This rotary actuation rotor assembly of turbine wheel rotates up in the side of arrow 134 ' around the central axis 64 ' of rotor case 4 ' as a whole.In other words, rotating shaft 78 '; Upper rotor part dish 80 '; Stacking 84 ' of separator disks 82 '; Fan disk 240; End plate 86 '; Splash guard dish 242; And the fan of combination and turbine unit 88 ' (that is, being jointly called rotor assembly in this article) as a whole assembly rotary shell 4 ' in and relative to described housing 4 ' and support plate 70 '; Housing insert 72 '; And turbine shroud rotates together.

Release from motor body and need the gas that processed by separator 2 ' to be introduced into separator 2 ' via the fluid intake 8 ' at the top being arranged in rotor case 4 '.As the arrow 68 ' in Figure 34 indicates, inlet gas enters rotor case 4 ' along direction that is parallel with central axis 64 ' and conllinear, and flows through three grooves 66 ' in top axle bearing unit 50 ' before 12 spokes 116 ' through upper rotor part dish 80 ' flow into the entrance 600 of rotor assembly.The rotary motion of 12 spokes 116 ' also can cause the lateral 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 case 4.In fact, 12 spokes 116 ' give columniform 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 case 4 ', as shown in the arrow 184 ' in Figure 34 via the space 602 between adjacent separator disks 82 '.By along this path, the direction of fluid stream changes more than 90 °.

To understand, 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 also will understand, and oil droplet 186 ' tends to move through separator disks at them and pooled together by time on the cylindrical wall of rotor case 4 ' of dishing out and form larger dripping.Once be received by described cylindrical wall, oil droplet 186 ' just tends to advance on support plate 70 ' under gravity downwards.The most external circumferential edge of separator stacking 84 ' is inwardly spaced apart fully relative to the cylindrical wall of rotor case 4 ', to allow oil droplet to advance in the clear on described support plate 70 ' downwards.O-ring packing 262 guarantees that oil droplet can not flow between support plate 70 ' and rotor case 4 '.

It will be appreciated by those skilled in the art that, due to the rotary motion of rotor assembly, the fluid pressure in rotor case 4 ' the peripheral edge place of support plate 70 ' and separator disks stacking 84 ' than the abutment wall 266 of housing insert 72 ' and top area element 268 and support plate 70 ' around region in larger.As a result, the cylindrical wall of Purge gas along rotor case 4 ' is tended to exist downwards and along the radially inside flowing of support plate 70 '.This fluid stream tends to be pushed to downwards by isolated oil droplet on the support plate 70 of below along cylindrical wall, and then radially inwardly promotes it by the aperture in the abutment wall 266 of housing insert 72 ' along support plate 70 '.This gaseous fluid stream indicates (see Figure 34) by arrow 188 '.Gaseous fluid stream radially-inwardly moves through the upper surface of support plate 70 ' towards the central round orifice opening's edge in housing insert 72 '.This stream crossing support plate 70 ' tends to, towards bottom bearing unit 90 ', isolated oil droplet is pushed through support plate 70, and described oil droplet can pass bottom bearing unit 90 '.The fan blade 140 ' of the fan of combination and the rotation of turbine unit 88 ' is tended in the region of bottom bearing unit 90 ', reduce the static pressure in turbine shroud (rotor case 4 ' is thereon attached during use), to aspirate oil droplet by bottom bearing unit 90 '.Fan blade 140 ' is then radially thrown into turbine shroud by described, and from turbine shroud, they can turn back to engine crankshaft housing.Meanwhile, the gaseous fluid flowing through support plate 70 ' is drawn upwardly the center port of inhaling by package case 72 ', to pass radially outwardly through between end plate 86 ' and fan disk 240.Then gaseous fluid leaves rotor case 4 ' by flowing through the described columniform part 211 of valve cell housing 12 ', and this part 211 is connected to housing insert 72 ' hermetically, and through housing insert outlet 150 ' and rotor case outlet 10 '.

Also will understand with reference to accompanying drawing, except the aperture of flowing on the upper surface of support plate 70 ' and flow through in the abutment wall 266 of housing insert 72 ', the alternative route between the upside of some downsides via end plate 86 ' in Purge gas and the isolating roof parts 268 of housing insert 72 ' flow to described columniform part 211.This alternative route is indicated by arrow 190 '.

To understand, as in the separator 2 of prior art, by the oil stream of the bottom bearing unit 90 ' of the separator 2 ' of improvement, there is on bearing unit useful lubricant effect.Top axle bearing unit 50 ' lubricates similarly by naturally appearing at the oily mist being upwards sent to top axle bearing unit 50 ' in turbine shroud and by the longitudinal flow path 92 ' of extend through rotating shaft 78 '.

The separator 2 ' of the improvement that prior art ALFDEX separator 2 or more describes can comprise the alternative devices for rotating rotating shaft 78 ' as shown in Figure 35 of accompanying drawing.With reference to Figure 35, will see, the Pelton impeller turbine before described is replaced by brushless electric motor 380, and the rotor 382 of this brushless electric motor 380 is in the lower end of support plate 70 " below is fixed to rotating shaft 78 ".Electro-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, will see, the electro-motor 380 of electrical motor driven layout is arranged in the housing 384 be fixed to by means of multiple threaded fastener 180 ' (Figure 35 only show one of them) on rotor case 4.Motor shell 384 is made up of upper part 386 and low portion 388, and they utilize suitable fastening means to be fixed on and go up each other, and has the O-ring packing 390 of the interface between them.Other impurity that O-ring packing 390 prevents dirt, water and/or is arranged in housing 384 outside undesirably leaks into the space of housing 384.By this way, electronic component (comprising printed circuit board (PCB) and/or other circuit) is kept apart with the material that can cause their damage and fault subsequently.

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

The upper end of the other separate section 394 (having Frusto-conical shape 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-ring packing 396.The low portion 388 that the lower end (having the diameter larger than its upper end) of frusto-conically shaped portion 394 abuts against motor shell 384 by means of another O-ring packing 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 form space thus, and electro-motor 380 is positioned at wherein, and rotating shaft 78 " lower end extend to wherein.On the opposite side of frusto-conically shaped portion 394, the remainder of described part 394 and upper part 386 and low portion 388 is formed overall by around the space/compartment 406 with sealing, electronics/electric member (such as, printed circuit board (PCB) 408) be contained in wherein, electrical power and control signal are supplied to electro-motor 380.Compartment 406 is not only opened relative to the outside seal of motor shell 384, but also opens relative to the space sealing that electro-motor 380 is positioned at wherein.Therefore prevent the contaminated oil flowing through this space when using separator from close to electronics/electric member and damage to them can be caused.

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

Connector 412 also extends through the aperture 414 in motor shell 384, to allow one or more electric lead (not shown) to be positioned at the outside of separator (such as, the vehicle be used for wherein with separator is associated), to be connected to the described electric supply/control member be contained in compartment 406.In other words, electric lead or multiple electric lead can be provided with the plug for being mechanically connected and being electrically connected with connector 412.This wire or multiple wire can carry the electrical power and/or control signal of arranging for electrical motor driven.Connector 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, will understand, compartment 406 can have different shapes.

The stator 400 of electro-motor 380 is fixed to the low portion 388 of motor shell 384.The radial inner portion forming the described frusto-conically shaped portion 394 sealed with cylindrical wall 392 defines the aperture with the diameter substantially equal with the inner most diameter of the stator 400 of electro-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 to make rotating shaft 78 thus " rotates.As above set forth, isolated oil transports through bottom bearing unit 90 downwards from rotor case 4.In the separator that the electrical motor driven being provided with Figure 35 is arranged, this isolated oil is discharged to the inside of motor shell 384 from bottom bearing unit, and is more particularly discharged in the space of the cylindrical wall 392 in upper case portion 386.Then isolated oil transports through the rotor 380 of electro-motor 380 and leaves motor shell 384 via the port 402 be positioned in lower housing section 388 below electro-motor 380.The operation of electro-motor 380 can not adversely be affected, because the electric lead of stator 400 is covered by one deck epoxy resin varnish with the oil that described rotor 382 and stator 400 come in contact through rotor 382 (or through the space rotor 382 and stator 400).

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

This technique uses rotary welding clamp 500, and it comprises stationary part 502 and is rotatably installed to the rotor portion 504 on stationary part 502.Stationary part 502 comprises circular discs 506, and it has the diameter equal with support plate 70 '.The geometry of circular discs 506 so to such an extent as to allow described circular discs 506 to be positioned to adjoin (as shown in Figure 40) with the mode identical with support plate 70 ' and rotor case 4 ' in the separator 2 ' assembled.Rotor portion 504 comprises the center that extends 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 lateral movement.The protuberance 512 that relative rotary motion between top axle bearing unit 50 ' and axle 508 is erect by the circular discs from head 510 prevents.Head 510 comprises three protuberances 512, and their mutually the same and around axle 508 rotations are equidistantly spaced apart.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.

Being 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 at one end the second end being at a distance provided with head 501 of axle 508.

In Figure 39 of accompanying drawing, rotary welding clamp 500 has been shown, this rotary welding clamp 500 has the top axle bearing unit 50 ' be 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 case 4 ', as shown in Figure 40.Circular discs 506 is positioned to the lower shoulder 148 ' of adjacent rotor case 4 '.More particularly, circumferential edge surface, radially portion 634 (formation datum level) registration of circular discs 506 becomes adjacent with the columniform inner surface 632 around the lower open end of rotor case 4 '.By this way, the lateral register of top axle bearing unit 50 ' relative to rotor case 4 ' is determined.Utilize the rotary welding clamp 500 being positioned at rotor case 4 ' by this way, the rotation of rotor portion 504 overlaps with the central axis 64 ' of the rotor case 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 place can be moved to from primary importance, in primary importance, described bearing unit 50 ' is spaced apart with the upper part of rotor case 4 ', in the second place, bearing unit 50 ' is forced into and the convex ridge 238 adjacent (see Figure 34) provided on rotor case 4 '.Top axle bearing unit 50 ' had been assembled into rotor case 4 ' upper period, rotor case 4 ' keeps fixing, and the circular discs 506 of stationary part 502 is positioned to adjoin with the lower shoulder 148 ' of rotor case 4 ' simultaneously, rotor portion 504 is to rotate relative to high speed, and move in rotor case 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 forcefully, to produce frictional heat, and makes the abutment surface melting of the plastic material of top axle bearing unit 50 ' and convex ridge 238 thus.While extruding bearing unit 50 ' against convex ridge 238, the rotary motion of axle 508 promptly reduces 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 case 4 ' are spun welded to thus to be gone up each other.

Rotor case 4 ' can by means of the lug boss 284 in extend through rotor case 4 ' and the threaded fastener extended in columniform installing rack 516 and keeping fixing (see Figure 40) during spin-welding process.
