Now will with reference to Fig. 8 the aforementioned internals that is held by rotor case 4 be described in more detail especially.

At 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 that catches between the step parts 56 of upper steel cap member 54 and plastic material.Bearing unit 50 is by making at upper steel cap member 54 molded about step parts 56, and wherein cage bearing 52 remains between them regularly.Being arranged among Fig. 8 of top axle bearing unit 50 clearly illustrate, 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 (around the bottom part of cap member 54), and it abuts against the cylindrical wall 60 of rotor case 4 along the side direction adjacency in the separator 2 that assembles.Help to guarantee that with cylindrical wall 60 adjacency top axle bearing unit 50 is with respect to the correct lateral register of rotor case 4.The second cylindrical wall 62 of rotor case 4 radially is positioned at the inboard of the first cylindrical wall 60, in order to guarantee that top axle bearing unit 50 is with respect to the correct axial location of 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 so that the rotation of top axle bearing unit 50 overlap with the central axis 64 of rotor case 4.

Three part circular grooves 66 (only having shown wherein two among Fig. 8) are provided in the top axle bearing unit 50, in order to allow inlet fluid to flow through wherein (as by shown in the arrow 68).Upper cap member 54 makes the inlet fluid deflection from cage bearing 52, but as the downside that it will be understood by those skilled in the art that the topmost part of cap member 54 also makes and upwards advances during use by armature spindle and the lubricating oil mist deflection (in cage bearing 52) that enters 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 the housing 4.Black box is included in when using separator 2 and keeps first group of fixing member with respect to rotor case 4, and when using separator 2 around central axis 64 with respect to rotor case 4 (with valve cell housing 12) and first group of second group of member that member rotates.

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

Second group of member forms rotor assembly and comprises rotating shaft 78, upper rotor part dish 80, forms stacking 84 a plurality of independent separator disks 82, end plate 86 of separator disks 82 and fan and the turbine unit 88 of combination together.This member of second group is according to going up in order to prevent that mode that they relative to each other rotate is fixed to each other.Yet second group of member rotatably is installed to first group of member by means of bottom bearing unit 90 (seeing especially Figure 10).

Now the rotor assembly that is formed by second group of member will be described in more detail.

Rotating shaft 78 is made by metal material, and has the ring section, in order to the fluid flow path 92 that extends longitudinally along its whole length is provided.When using separator 2, this flow path 92 allows oily mist upwards to transmit by rotating shaft and be sent to the top axle bearing unit 50 from turbine shroud, so that the bearing of lubricated described unit 50.The flow restrictor element 93 of annular disk (having the cylindrical wall of erectting from its radially outer circumferential edge) form is located on the inside shoulder facing up of described fluid flow path 92 of upper end of rotating shaft 78.Flow restrictor element 93 works at the flow path area (thereby nozzle be provided) of the exit minimizing that enters top axle bearing unit 50 from rotating shaft 78 by rotating shaft 78.

The outside of rotating shaft 78 is provided with some recess and shoulders of be used for receiving back-up ring, and back-up ring helps member is remained on correct axial location on the rotating shaft 78.A this back-up ring 94 clearly is shown in Fig. 6 and provides shoulder facing up, packing ring 95 to abut against this back-up ring 94 and adjacency.Spiral compression spring 96 is in abutting connection with the shoulder facing up of packing ring 95.The peripheral recess that back-up ring 94 is positioned at wherein has enough width (that is, the size on the axial direction of recess), and is mobile 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, to be used for the member location and to remain on described axle 78.

In upper rotor part dish 80, separator disks 82 and the end plate 86 each has frusto-conically shaped portion (defining fi-ustoconical surface 102), wherein a plurality of spoke parts radially extend inward into the hub element from them, and this hub element is positioned at around the rotating shaft 78 in use.

Although the spoke parts of upper rotor part dish 80 and separator disks 82 have unlimited space between them, to allow fluid to flow through vertically them along rotating shaft 78, but the spoke parts of end plate 86 are attached to each other at their lower surface place and go up, and flow vertically in order to prevent fluid along rotating shaft 78 or be upward through end plate 86 or be passed down through end plate 86.

The Frusto-conical geometry of upper rotor part dish 80 and end plate 86 and the geometry of separator disks 82 are basic identical, in order 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 place, top of separator disks stacking 84, and end plate 86 is positioned at the place, bottom of separator disks stacking 84.In addition, although it is thinner that the technical staff will understand separator disks 82, in order 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 are much thicker than separator disks 82, so that the place, two ends at dish stacking 84 provides rigidity, and allow thus the compression axial force to be applied to equably the frusto-conically shaped portion of separator disks by upper dish 80 and end plate 86.Compression stress is more specifically produced by the spiral compression spring 96 on the downside of the hub 98 that upwards is pressed in end plate 86.

Stacking 84 about compact disk between upper dish 80 and end plate 86, the technical staff will understand, and the adjacent separator disks 82 in stacking 84 must keep being spaced apart from each other, so that the permission flow is crossed separator 2.A plurality of ribs 100 that this interval of separator disks 82 provides by means of the upper surface on the frusto-conically shaped portion of each separator disks 82 (being called the joint filling part) and providing.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 (stand proud of), and the separator disks 82 that assembles stacking 84 in, the downside of the adjacent dish of abut upper.As the skilled person will appreciate, each separator disks 82 can be positioned on the rotating shaft 78 with respect to one in only six feasible positions, angle of rotating shaft 78, and joint filling part 100 in the location on the described upper surface 102 so that the joint filling part of adjacent dish 82 is aligned with each other must be on dish 82 any one that are arranged in these six positions the time.As a result, the compression stress that is applied on the dish stacking 84 by end plate 86 passes through stacking 84 by means of the joint filling part 100 of alignment in the inc situation in the interval between the adjacent separator disks 82.

About being applied to the compression stress of separator disks stacking 84, the technical staff will understand in addition, and this power is produced and is applied on the end plate hub 98 by spiral compression spring 96.Because the rigidity of end plate 86, compression stress are delivered to the frusto-conically shaped portion 108 of end plate 86 from hub 98 by a plurality of spokes 110 that radially extend of end plate 86.It is stacking 84 that then compression stress is delivered to dish by frusto-conically shaped portion 108, and upwards be 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 116 that radially extend.Compression stress can be delivered to hub 114 from frusto-conically shaped portion 112 owing to the rigidity of upper rotor part dish 80.The axially-movable that makes progress along rotating shaft 78 that 80 pairs of compression stresses of upper rotor part dish are reacted is by preventing (seeing especially Fig. 6) in the peripheral recess 118 in the outer surface that upper rotor part hub 114 is positioned at 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 downwards extends to point directly over end plate hub 98 along rotating shaft 78 vertically.More particularly, hub 114 extends along the entire depth of separator disks stacking 84, and makes thus the hub 120 of each separator disks 82 separate (seeing Fig. 7) with rotating shaft 78.The hub 120 of each separator disks 82 has the hex shape that limits the hexagon aperture, and rotating shaft 78 and upper rotor part hub 114 extend through this hexagon aperture.Separator hub 120 with respect to upper rotor part hub 114 (and therefore, with respect to rotating shaft 78) rotatablely move and 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 that is limited by separator hub 120.This position of key 122 prevents separator hub 120 with respect to the side direction of rotating shaft 78 and rotatablely moves.

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 126 that radially extend.Spoke 126 (and in fact being the remainder of the separator disks 82 that is associated) is made by relative thin and can be flexibly crooked plastic material.Yet spoke 126 still can resist side direction that they stand and revolving force and be indeformable.The technical staff will understand, and the compression stress that helical spring 96 produces passes through separator disks stacking 84 via joint filling part 100 rather than by separator plate convergence 126.

The technical staff also will understand, and the hexagon hub 120 of each separator disks 82 and the relative geometry of key 122 guarantee that one that each separator disks 82 as mentioned above can be in position, six angles only is positioned on the rotating shaft 78.Yet, no matter use in the position, six angles which, the utmost point position of the joint filling part 100 of separator disks 82 or position, angle all are identical, and therefore, do not have such possibility: separator disks stacking 84 is assembled on the rotating shaft 78 in the joint filling part 100 unjustified situations of adjacent separator disks 82.

For clear, some figure in the accompanying drawing has shown that the dish of the separator disks that has the quantity that reduces 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.The second recess 128 receives the second spiral compression spring 130.The position of the second recess so that, in the prior art separator 2 that assembles, the hub 114 spaced apart (seeing Fig. 6) of the lower end of the second spring 130 and upper rotor part dish 80, and prevented that by the shoulder facing up that is formed by the second recess 128 lower end of the second spring 130 is along the downward axially-movable of rotating shaft 78.In addition, in the separator 2 that assembles, the cage of cage bearing 52 in abutting connection with and to lower compression the second spring 130 (wherein seeing especially Fig. 8 every opening – between the maintenances of the cap member 54 of the upper end of rotating shaft 78 and top axle bearing unit 50).The second spring 130 arrives top axle bearing unit 50 with load applying, and reduces thus the vibration and the wearing and tearing that are associated at top axle bearing unit 50 places.

Assembling except the fan of combination and all members the turbine unit 88 are shown as in Fig. 6 of accompanying drawing in second group of internals.When fan/turbine unit 88 was installed to the lower end of rotating shaft 78, the lower end of axle 78 the central circular aperture that provides in the support plate 70 of first group of internals and in the housing plug-in unit 72 each was provided and locates.Like this, the lower end of rotating shaft 78 also extends through the bottom bearing unit 90 (seeing especially Fig. 8 and 10) on the center port that is fixed to support plate 70.

The fan of combination and turbine unit 88 are fixed to from the lower end of the downward rotating shaft 78 of giving prominence to of downside of support plate 70.Fan/turbine unit 88 is held in place in the lower end of rotating shaft 78 by means of second packing ring 133 on the surface facing up of the second back-up ring 132 (remaining in the 3rd peripheral recess in the axle 78) and adjacency the second back-up ring 132.The axial location of fan/turbine unit 88 on rotating shaft 88 of being determined by the second back-up ring 132 causes the upper surface of unit 88 to be forced into and deflection packing ring 139 adjacency, and deflection packing ring 139 is forced into again and bottom bearing unit 90 adjacency.In the separator 2 that assembles, the inside race of bottom bearing unit 90 is upwards pressed this back-up ring 94 in abutting connection with the first back-up ring 94 and the bias voltage that resists the first Compress Spring 96.To such an extent as to press inside races, deflection packing ring 139 and fan/turbine unit 88 so these elements to be remained on fixing position of rotation with respect to rotating shaft 78 facing to the second back-up ring 132.

The rotor assembly of separator 2 rotates along arrow 134 (seeing Fig. 1) indicated direction by means of the hydraulic impulse turbine.Fan/turbine unit 88 comprises Pelton impeller 136, and this Pelton impeller 136 has a plurality of wheel blades 138 that are 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 the turbine shroud 178.More particularly, jet is along the tangent line guiding of the circle that passes a plurality of wheel blades 138, so that this jet enters wheel blade (with its surface in alignment).Jet flows along the described surface of the in-profile of following wheel blade, and is turned to by described profile afterwards, in order to flow along other surface, and discharges from wheel blade afterwards.The result is that jet makes impeller 136 rotations.

Fan with a plurality of blades 140 also forms with impeller 136.Blade 140 is close to the downside of support plates 70 and is positioned on the impeller 136.A plurality of fan blade 140 also are 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 is around central axis 64 rotations when turbine wheel 136 rotation.Like this, fan blade 140 is dished out fluid effectively from the zone between the downside of impeller 136 and support plate 70, thereby reduce the fluid pressure in the zone of bottom bearing 90, and from the position of support plate 70 tops isolated oil pumped by the bottom bearing unit downwards and enter the turbine shroud 178 of support plate 70 belows.

For the ease of making, impeller 136 is made top part 142 and bottom part 144, and is pressed onto at line 146 places shown in Fig. 8 of accompanying drawing and is adjacent to each other.

About first group of internals, support plate 70 is formed from steel and has round-shapedly, and this is round-shaped to have the diameter that substantially equates with the diameter of rotor case 4.To such an extent as to relative geometry so allows support plate 70 to be located on the prone shoulder 148 of lower end of rotor case 4.By this way, the lower open end of rotor case 4 is by support plate 70 sealings.Support plate 70 also is provided with the central circular aperture, and this central circular aperture is concentric with rotor case 4 in the separator 2 that assembles.In other words, in the separator 2 that assembles, the circular central aperture of support plate 70 is centered by the central axis 64 of rotor case 4.In addition, as will be obvious especially from Fig. 1 of accompanying drawing, bottom bearing unit 90 be received in the center port of support plate 70.The radially most external part of bottom bearing unit 90 is fixing with respect to support plate 70.The radially penetralia of bottom bearing unit 90 partly is positioned near the rotating shaft 78, but is not fixed to the upper.

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

The columniform skirt part 152 of housing plug-in unit 72 has the most external external diameter that substantially equals with the diameter of the inner wall section of the rotor case 4 of skirt part 152 adjacency.Peripheral recess 159 (seeing Figure 12) is provided in the outer surface of skirt part 152, in order to receive O-ring packing 160, this O-ring packing 160 is guaranteed the Fluid Sealing between the housing plug-in unit 72 chord transcapsidation body 4 in the separator 2 that assembles.

The lower end of columniform skirt part 152 is in abutting connection with the upside of support plate 70, and is provided with for the peripheral recess 162 (seeing Figure 12) that receives the second O-ring packing 164.To understand, the second O-ring packing 164 has been guaranteed the Fluid Sealing between housing plug-in unit 72 and the support plate 70.

The radially inner side and concentric the second cylindrical wall arranged that are positioned at external skirt part 152 are connected to skirt part 152 at its lower end, to form ditch part 154.Ditch part 154 forms the annular ditch (or groove) 166 that extends along the interior cylindrical wall of rotor case 4 with external skirt part 152.Ditch 166 has the cross section of U-shape, and during using separator 2, compile the isolated oil droplet of dishing out and advancing in (and under effect of the gas flow that spirals downwards, as described in more detail) under the action of gravitation in the inside of rotor case 4 from separator disks 82 downwards herein.Ditch part 154 is provided with four discharge orifices 168 (seeing especially Figure 11), the oil that collects in the ditch 166 can flow by this four discharge orifices 168, enters the zone that the upside by the downside of housing plug-in unit 72 and support plate 70 centers in order to transmit during using separator 2.

The third part 156 of housing plug-in unit 72 has Frusto-conical shape, and hangs from ditch part 154.Frusto-conically shaped portion 156 is provided with the central circular aperture, and this central circular aperture has the central axis that overlaps with the central axis 64 of rotor case 4 in the separator 2 that assembles.Elongated recesses 170 (seeing Figure 11) is provided in the upper surface of frusto-conically shaped portion 156.This recess 170 defines the fluid path that links for exit portion 158 Purge gas and housing plug-in unit 72.This flow path that is 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 plug-in unit 72 along with fluid path and increases height at downstream direction.With apparent, recess 170 provides half the straight fluid path of length with diameter of being substantially equal to housing plug-in unit 72 such as the top view of the housing plug-in unit 72 that provides from Figure 11.

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

The view that in Fig. 2, has shown the separator 2 that is fixed on the turbine shroud 178.Separator 2 is fixed on the turbine shroud 178 by means of three threaded securing members 180, and each in the securing member 180 passes in three lug bosses of lower end all-in-one-piece with rotor case 4.A securing member 180 and lug boss 182 only in the side cross-sectional view of Fig. 2, have been shown.Those skilled in the art will understand from Fig. 2, support plate 70 (and, therefore all members of first group and second group) remain on desired location with respect to rotor case 4 by means of turbine shroud 178, turbine shroud 178 is fastened to when going up each other at rotor case 4 and turbine shroud 178 support plate 70 is depressed into and prone shoulder 148 adjacency.Support plate 70 is clamped between rotor case 4 and the turbine shroud 178 by means of threaded securing member 180 substantially.Because threaded securing member 180 is tightened, and so that support plate 70 with shoulder 148 adjacency occurs, so the second spiral compression spring 130 is by 50 compressions of top axle bearing unit.

When separator 2 operation, the nozzle (not shown) in the turbine shroud 178 is directed to the jet of oil on the turbine wheel 136, so as on the indicated direction of arrow 134 the revolving wormgear impeller, as previously described with respect to FIG 1.This rotary actuation rotor assembly of turbine wheel as a whole on the direction of arrow 134 around central axis 64 rotation of rotor case 4.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, jointly being called in this article rotor assembly) are together as the black box in the rotary shell 4 and with respect to described housing 4 and support plate 70, housing plug-in unit 72 and turbine shroud 178 rotations.

The fluid intake 8 at the top of the gas of emitting and need to being processed by separator 2 from the engine crankshaft housing by being positioned at rotor case 4 is introduced into separator 2.As by shown in the arrow 68 among Fig. 8, inlet gas is being parallel to central axis 64 and is entering rotor case 4 with the direction of central axis 64 conllinear, and flows through three grooves 66 in the top axle bearing unit 50 before flowing through six spokes 116 of upper rotor part dish 80.Rotatablely moving 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, six spokes 116 are given inlet gas with columniform motion.

Inlet gas is downward through the spoke 116,126 of upper rotor part dish 80 and separator disks 82, and this gas moves along the cylindrical wall of side direction towards rotor case 4 via the space between the adjacent separator disks 82, shown in the arrow 184 among Fig. 8.Joint filling part 100 is given lateral movement with the frictional force that is applied by separator disks 82 to the fluid that is arranged in dish stacking 84, and this can cause described fluid outwards to move towards the cylindrical wall of rotor case 4.This motion of the fluid that is caused by dish stacking 84 rotation is that fluid is drawn into the main mechanism that adopts in the separator 2.

It will be understood by those skilled in the art that oil droplet 186 tends to pool together and form larger dripping at the periphery place of dish stacking 84.In this regard, act on capillary force on the less oil droplet (because the little spacing between the adjacent separator disks 82) and tend to prevent that droplet from dishing out from coiling stacking 84.Yet, along with more oil moves through separator disks, pool together at the periphery place than droplet, and form larger the dripping with the quality (and " centrifugal " power that is associated) that is enough to overcome capillary force.Spontaneously throw afterwards on the cylindrical wall of rotor case 4.In case received by described cylindrical wall, oil droplet 186 just tends to advance to downwards in the annular ditch 166 under the effect of gravity and the gas flow by separator 2.The most external circumferential edge of separator stacking 84 is inwardly spaced apart fully with respect to the cylindrical wall of rotor case 4, so that the permission oil droplet is not subjected to the obstruction of separator disks 82 and advances to downwards in the described ditch 166.O-ring packing 160 guarantees that oil droplet flows into ditch 166, rather than between housing plug-in unit 72 and the rotor case 4 (it has the possible consequence (will be more readily understood such as reference Fig. 1) of gas of cleaning that contaminated stream is crossed the outlet 150 of housing plug-in unit 72).

The oil droplet 186 that collects in the ditch 166 therefrom emits by four discharge orifices 168.This discharging effect is auxiliary by the FPG in rotor case 4 and the turbine shroud 178.More particularly, it will be understood by those skilled in the art that because the rotatablely moving of rotor assembly, the fluid pressure in the rotor case 4 is larger in than the zone between the upside of the downside of housing plug-in unit 72 and support plate 70 at the peripheral edge place of separator disks stacking 84.As a result, tend to exist downward purge gas flow by discharge orifice 168.This flow tends to promote isolated oil droplet along annular ditch 166, and promotes it and arrives on the following support plate 70 by discharge orifice 168 downwards.This gaseous fluid stream is by arrow 188 indications (seeing especially Fig. 8).The central round orifice opening's edge of gaseous fluid stream in housing plug-in unit 72 radially moves inward the upper surface through support plate 70.This stream of crossing support plate 70 tends to promote isolated oil droplet and crosses support plate 70 towards bottom bearing unit 90, and described oil droplet passes this bottom bearing unit 90.The fan blade 140 of the fan of combination and the rotation of turbine unit 88 tends to reduce the static pressure in the turbine shroud 178 in the zone of bottom bearing unit 90.This helps again to extract oil droplet by bottom bearing unit 90.Yet, pumping oil droplet is provided by deflection packing ring 139 by the major measure that bottom bearing unit 90 adopts, in use, this deflection packing ring 139 rotates with respect to support plate 70 with turbine unit, and from rotor case 4 pump oil, even if also be like this when the pressure in the pressure ratio rotor case in the turbine shroud is larger.Then fan blade 140 is outwards thrown in the turbine shroud 178 described, and they can turn back to the engine crankshaft housing from this turbine shroud 178.Simultaneously, the gaseous fluid that flows through support plate 70 is upwards pumped the center port by package case 72, and leaves rotor case 4 by means of the outlet 150 of housing plug-in unit and rotor case outlet 10.

Also will understand with reference to accompanying drawing, except flowing through discharge orifice 168, some in the Purge gas flow to outlet 150,10 (not flowing in the ditch 166) via the alternative route between the top part of end plate 86 and ditch part 154.This alternative route is by arrow 190 indications.

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

Although prior art separator 2 has proved effectively operation, the problem that exists some to be associated with this separator, they have utilized the improvement that exists in the modified separator of describing hereinafter and have been solved.These problems can be thought three wide in range classifications.

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

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

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

To discuss in more detail now all kinds of in these classifications.

There are some positions in fluid flow path about by this separator 2, can experience the higher pressure loss in these positions.At first, inlet/outlet pipe joint 22 is to such an extent as to the interior turning 40 of the elbow in 28 is too sharply in the separation from the inner surface of pipe joint of the region generating fluid in the direct downstream at described interior turning 40.This separation self shows as recirculated fluid stream (or whirlpool), and it can cause energy/pressure loss again.Yet, describe such as above Fig. 4 about accompanying drawing, utilize injection-molded or die-casting technique to provide large radius at interior turning when making the inlet/outlet pipe joint be problematic.As a result, prior art separator 2 is when fluid enters rotor case 4 and leave in 12 two kinds of situations of valve cell housing the experience pressure loss at the pipe joint place.

The inventor has realized that six spokes 116 of upper rotor part dish 80 are other reasons of undesirable pressure loss.Particularly, will see especially from Fig. 5 and 6, spoke 116 has the square-section separately, and they present sharp-pointed upper trailing edge (see Fig. 5) to the axial flow of emitting gas that enters at upper rotor part dish 80 when the direction of arrow 134 is rotated.Have been found that the sharp-pointed trailing edge 192 of the shape of spoke 116, particularly each spoke, can cause that fluid separates and undesirable pressure loss.

The inventor finds that also the specific structure of housing plug-in unit 72 can cause undesirable pressure loss.Particularly, during using separator 2, Purge gas is with as by being downward through the frusto-conically shaped portion 156 of housing plug-in unit 72 around rotatablely moving of central axis 64 shown in the arrow 194 among Figure 12.This purge gas flow is flowing through frusto-conically shaped portion 156 after the inner surface of the columniform sidewall of rotor case 4 flows downward with the pattern of spiraling.To understand, therefore, Purge gas is from the zone between the end plate 86 that enters a little frusto-conically shaped portion 156 and top along housing plug-in unit 72 all peritropous (rather than enter described zone a specific position).Therefore the flow path that strides across frusto-conically shaped portion 156 has the 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 the frusto-conically shaped portion 156 produce other flow separation zone territory, and the undesirable pressure loss that is associated.

About the Equations of The Second Kind problem relevant with oil pollution, the inventor has realized that some features of the prior art separator 2 of the possibility that the air of meeting raising purification is polluted under certain conditions.At first, as described above, downwards the stream of the Purge gas by rotor case 4 partly enters ditch 166 and tends to and extracts isolated oil droplet out by discharge orifice 168.If the flow rate of the air that purifies is enough not high for the specified level of processed oil pollution, the oil droplet that then collects in the ditch 166 can be climbed up the ditch part 154 of housing plug-in unit 72, and then flows on the frusto-conically shaped portion 156 of housing plug-in unit 72 (seeing Figure 10).In case oil droplet enters the zone between frusto-conically shaped portion 156 and the end plate 86, oil droplet is removing pollutant gas with regard to leaving inevitably separator 2.It may be to allow desirably not a large amount of oil to collect in the result of the low flow rate of the Purge gas the ditch 166 that oil droplet climbs from ditch 166.Also can tend to upwards extract oil droplet in the Purge gas that ditch 166 interior existence upwards circulate, and it is drawn on the frusto-conically shaped portion 156 of housing plug-in unit 72.Yet allowing the climb notable feature of prior art separator 2 of emersion ditch 166 of oil droplet is pipe-type outlet part 158 (seeing Figure 12).Although discharge orifice 168 is positioned on the both sides of exit portion 158, but from Figure 12 of accompanying drawing, will understand, oil droplet in the ditch 166 is deferred to along the circular path of the bottom of ditch 166, if and oil droplet is not crossed discharge orifice 168 in the direct upstream flow of exit portion 158, then oil droplet will tend to defer to the path of arrow 196 (seeing Figure 12) indication, and upwards flow through exit portion 158 and flow on the frusto-conically shaped portion 156 of housing plug-in unit 72.

The inventor finds that also isolated oil droplet can upwards flow through the center port of housing plug-in unit 72 and flows on the frusto-conically shaped portion 156, and removing pollutant gas thus.The undesirable stream of this of isolated oil tends to occuring by discharge orifice 168 and when upwards the flow rate of the Purge gas of the center port (indicated such as the arrow 188 among Fig. 8) by housing plug-in unit 72 is relatively high.It will be appreciated by those skilled in the art that, the high flow rate of Purge gas causes isolated oil droplet upwards to be carried center port by housing plug-in unit 72, rather than allows isolated oil droplet to pump by bottom bearing unit 90 by the effect of gravity and deflection packing ring 139 downwards.

The inventor also finds, it is stacking 84 that too much oil can be introduced into via the longitudinal flow path 92 of passing rotating shaft 78 separator disks, as indicated by the arrow 198 as shown in Fig. 2.During normal operating condition, drive turbine wheel 136 oil the described impeller of jet impulse and produce the mist of thin oil droplet.This mist of oil upwards is sent to top axle bearing unit 50, and then transmits downwards and pass through the stacking of separator disks 82.Generally, the amount of the oil that transmits by this way is enough to lubricated top axle bearing unit 50, also easily isolates from the gas flow that enters by separator disks stacking 84 subsequently simultaneously.Yet, in some cases, transmit the amount of the oil by rotating shaft 78 may be greatly to causing oil spill to go out ditch 166 or otherwise flow on the frusto-conically shaped portion 156 of housing plug-in unit 72, and flow into subsequently purified gas outlet 10.This can be for example tilts and the lower end of rotating shaft 78 occurs directly be exposed to the oil storage that remains in the turbine shroud 178 surperficial the time at separator 2.

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

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

Make that duration that prior art separator 2 spends also is subject to needing top axle bearing unit 50 with bottom bearing unit 90 so that the impact that two bearing

units

50,90 can align vertically around the mode of same axis 64 rotations.Particularly, rotor case 4 is made by plastic material by means of injection molding process, and the inventor finds that during cooling there is the tendency of warpage in rotor case 4.Because this warpage, the position of the first cylindrical wall 60 of rotor case 4 (it is along lateral register top axle bearing unit 50) is tended to and is expected that the lower end of comparing with respect to rotor case 4 is positioned at different lateral positions.As a result, support plate 70 (and so bottom bearing unit 90) can become from its desired location along laterally offset.This problem can alleviate in relatively long time period cooling after injection molding process by allowing rotor case 4.This length section cool time has reduced the warpage of rotor case 4, but has increased manufacturing time.

Relate between the different members from the other problem that the assembling of separator 2 is associated, such as the interface between rotor case 4 and the valve cell housing 12.More particularly, if separator 2 will be provided with the valve cell 14 (perhaps in fact just do not have valve cell) different from desired valve cell originally, then must also use different rotor housing 4, in order to guarantee correct the engaging with new valve cell (perhaps in the situation that will not use valve cell for other pipe-line system).This can raise the cost and built-up time inadequately.In addition, asymmetric (being caused by the moulded parts profile that is used for engaging with valve cell housing 12 that provides at described housing 4) of rotor case 4 tends to cause during manufacture described housing 4 warpages, and this tends to cause the problem unjustified relevant problem of member (for example, with) at assembly process.

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

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

The inventor also recognizes and the integrity problem that is used for being associated with the layout of fixing angular orientation positioning separator dish 82 with respect to rotating shaft 78.Set forth such as above Fig. 7 about accompanying drawing, prevent that by means of six keys (being fixed on the rotating shaft 78) that engage with hexagon aperture in hub 120 or each separator disks 82 separator disks 82 is with respect to rotating shaft 78 rotations.Yet the vibration that separator typically is exposed to during use (such as engine luggine) can cause the wearing and tearing of the interface between the hexagon aperture in key 122 and the hub 120.These wearing and tearing can cause the significant relative rotary motion between separator disks 82 and the rotating shaft 78.In fact, the inventor has been found that adjacent separator disks 82 can relative to each other be rotated and reaches the joint filling part 100 unjustified degree that becomes, thereby allows the space between the adjacent separator disks 82 closed.If this occurs in a large number of dish 82, then the degree of depth of separator disks stacking 84 can reduce to so that the hub 98 of end plate 86 is abutted against the degree of upper rotor part hub 114 compressions by Compress Spring 96.To understand, it is stacking 84 that then end plate 86 no longer can be delivered to compression stress separator disks, and the result, independent separator disks 82 can be freely vertically along rotating shaft 78 move up and down (and with respect to rotating shaft 78 rotations).This motion is very undesirable, and can reduce significantly the separating property of separator disks stacking 84.

The other integrity problem that the inventor recognizes relates between (i) rotating shaft 78 and the top/

bottom bearing unit

50,90; 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 generation when the fretting wear erosion may have relative motion (for example, because the relatively cooperation of pine between the described member) between member.Rotating shaft 78 extends through top and

bottom bearing unit

50,90 and the first Compress Spring 96 with relatively more loose cooperation.This allows by the first and second Compress Springs 96,130 axial prestrain to be applied to top and bottom bearing unit 50,90.Particularly, will understand from accompanying drawing, 96 pairs of bottom bearing unit 90 of the first Compress Spring apply axial force, and 130 pairs of top axle bearing units 130 of the second Compress Spring apply axial force.The loose fit of rotating shaft 78 and top/

bottom bearing unit

50,90 and the first Compress Spring 96 allows the oscillating movement between these members.This can cause again the fretting wear erosion on the described member.Relative motion between the member also can allow hard particle to enter between the described member, this further accelerated wear test and cause integrity problem.

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

Those skilled in the art will understand inventor exploitation immediately from accompanying drawing improved separator has many and prior art separator 2 similar or identical member aspect their performed functions and their ordinary construction.Such member will be described in the context of improved separator about prior art separator 2 employed identical reference numbers with above hereinafter by using.For example, with reference to Figure 13 of accompanying drawing, the technical staff will understand, and improved separator 2 ' shown in this Fig comprises the rotor case 4 ' of general cylindrical, and it is corresponding to the rotor case 4 of prior art separator 2 and carry out similar function.Pass through accompanying drawing, 26S Proteasome Structure and Function difference between the member of such correspondence will be apparent for technical personnel, but when difference solve about prior art separator 2 or make prior art separator 2 technique problem and when obvious when providing with respect to prior art separator 2 or the improvement of technique of making prior art separator 2, will substantially at length discuss these differences.

It will be understood by those skilled in the art that in improved separator 2 ' rotor case 4 ' that comprises general cylindrical shape and the gas of emitting that works from be directed to described rotor case 4 ' and separate some fuel-displaced internals.As mentioned below, some in the internals are positioned at rotor case 4 ', and other internals (for example, fan and the turbine unit of combination) be positioned at the outside of rotor case 4 ', however, be positioned in another housing (for example, turbine shroud).

The upper end of columniform housing 4 ' is provided with the annular shoulder 6 ' of setting, and it defines the fluid intake 8 ' that leads to improved separator 2 '.The gas of emitting and need to therefrom remove oil from crankshaft shell enters 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 especially Figure 13,14 and 15) of valve cell 14 ' from the inside of rotor case 4 '.Outlet aperture 10 ' extends through and is therefore centered on by columniform lug boss 202, and these columniform lug boss 202 outer surfaces from rotor case 4 ' own extend.

Valve cell 14 ' comprises for control to be arranged from the valve that flows of the Purge gas of separator 2 '.Because to the above description of prior art separator 2, the details of the operation of valve cell 14 ' will can not described herein.Yet, the technical staff will be familiar with for improvement of the feature operation of valve cell of separator.

As from Figure 13 and 14 with apparent, and particularly from Figure 15 with apparent, the internals of valve cell 14 ' integrally is centered around in the housing 12 ' that separates with rotor case 4 '.More particularly, valve cell housing 12 ' comprises first 203 and second portion 205, and they are fitted to each other to form the enclosure space of sealing, and the internals of valve cell 14 ' is arranged in this space.With reference to Figure 15, will see, the upper end of the first 203 of valve cell housing 12 ' is provided with lug boss 207, and traditional threaded fastener 16 ' extends through this lug boss 207, in order to be threadedly engaged with other lug boss 209 on the rotor case 4 '.

Also will see from Figure 15, the lower end of the first 203 of valve cell housing 12 ' is provided with the part 211 of general cylindrical, this part 211 is extended away from valve cell housing 12 ', and extends to the inside of rotor case 4 ' via the outlet aperture 10 ' in the rotor case 4 '.O-ring packing 213 is positioned on the outer surface of columniform part 211, and against shoulder (being limited on the described surface) and adjacency, this shoulder in the separator 2 ' that assembles towards the inside of rotor case 4 '.When assembly process promoted described part 211 by outlet aperture 10 ', shoulder prevented that thus O-ring packing 213 from moving along the undesirable of columniform part 211, and O-ring packing 213 engages with described aperture 10 '.More particularly, O-ring packing 213 with around the face seal of the interior cylindrical of the lug boss 202 of oral pore mouth 10 ' engage.

When O-ring packing 213 towards the root end of columniform part 211 (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.With in the situation that the first O-ring packing 213 is identical, the second O-ring packing 215 abuts against on the shoulder of the inside of rotor case 4 ', in order to prevent undesirable motion of the second O-ring packing 215 when being pressed into final use location in the separator 2 ' that described seal is assembling.More particularly, will understand from Figure 15, in the separator 2 ' that assembles, the second O-ring packing 215 engages hermetically with the outlet 150 ' of housing plug-in unit 72 '.

The technical staff also will understand, and the first O-ring packing 213 prevents that Purge gas and/or oil droplet from leaking between rotor case 4 ' and valve cell housing 12 ', and prevents that them from desirably not leaking into the environment from separator 2 ' thus.The technical staff also will be further understood that in addition, and the second O-ring packing 215 prevents that oil droplet from leaking into the outlet 150 ' of housing plug-in unit 72 ' and polluting thus the Purge gas of leaving rotor case 4 ' via columniform part 211.Columniform part 211 and the first and second O-ring packings 213,215 little external diameter (comparing with the major diameter O-ring packing 160 of prior art separator 2) allows to use the foozle of less, this error is guaranteed the less trouble about two O-ring packings 213,215.In this regard, will understand, for example, 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 first 203 of valve cell housing 12 ' is provided with the second lug boss 207 on the side that is positioned at columniform part 211.The situation of the first lug boss 207 that provides with upper end in first 203 is identical, the second lug boss 207 on the lower end of first 203 receives traditional threaded fastener 16 ', in order to be threadedly engaged with (seeing Figure 18 about described the second lug boss 207,209) with the second lug boss 209 that provides on the lower end of rotor case 4 '.

Because valve cell housing 12 ' is the housing that separates with rotor case 4 ', and independent (except coupling and the above and below lug boss 207 of columniform part 211 with outlet aperture 10 ' with it on how much, outside 209 pairs the joint), the rotor case 4 ' of improved separator 2 ' has with the rotor case 4 of prior art separator 2 compares the more closely overall shape of similar cylindrical overall shape.In this regard, notice that prior art rotor case 4 comprises the relative complex of the part that works to form prior art valve cell housing 12 (and be not only about it matched interfaces) and huge moulded parts profile in a side.Yet, with reference to Figure 15, will see, the rotor case 4 ' of improved separator 2 ' does not comprise aforementioned complexity and huge moulded parts profile.

Because rotor case 4 ' has the shape that approaches with cylindrical shape, housing 4 ' can use injection moulding technology to form with the amount of warpage manufacturing of comparing minimizing during process for cooling with the housing 4 of prior art separator 2.This allows more easily to make top and bottom bearing unit 50 ', 90 ' to align vertically.In addition, to understand, rotor case 4 ' shown in the accompanying drawing can connect-need only alternative valve cell with the alternative valve cell of the valve cell 14 ' shown in the accompanying drawing and have the columniform part 211 that is applicable to the outlet aperture 10 ' coupling of rotor case 4 ', and is applicable to the lug boss 207 with lug boss 209 couplings (in the situation of valve cell housing 12 ' as shown in Figure 15) of rotor case 4 '.For example, if alternative valve cell have with the columniform part identical with the columniform part 211 shown in Figure 15 and lug boss 207 and two lug bosses and with the housing of relative positioning identical shown in Figure 15, then compare with the valve cell housing 12 ' shown in Figure 15 can be much bigger for alternative housing, and hold with the inner valve of the valve cell 14 ' shown in the accompanying drawing and arrange that diverse inner valve arranges.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 ' that defines fluid issuing, and by this fluid issuing, Purge gas spreads out of from separator 2 '.Basic identical with the annular shoulder 6 ' that provides at rotor case 4 ' at the annular shoulder 18 ' that valve cell housing 12 ' provides.Because their similitude, entrance shoulder 6 can receive the inlet/outlet pipe joint with identical interface profile interchangeably with outlet shoulder 18.Shown the identical inlet/outlet pipe joint 22 ' with 90 ° of elbows among Figure 13.Shown the shoulder 6 ' coupling of inlet tube joint 22 ' and rotor case 4 ' with the cross section, and in Figure 17, be shown as in addition with described shoulder 6 ' and separate.

As will being clear that from the side cross-sectional view of Figure 16, the inner surface 216 of pipe joint 22 ' and the curved surface of shoulder 6 ' make up to limit the fluid flow path that has 90 ° of elbows and have outside significantly radius on turning and the interior turning.As a result, compare with the flow at the sharp-pointed turning 40 of arranging through prior art, the trend that fluid separates from the interior turning of elbow has reduced more.Then also reduced the pressure loss.

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

As shown in Figure 16 and 17, the setting shoulder 6 ' of rotor case 4 ' is provided as annular relief, this annular relief have by with longitudinal axis that the central axis 64 ' of rotor case 4 ' overlaps centered by general cylindrical wall 217.The free end of cylindrical wall 217 (in the distant place of the remainder of rotor case 4 ') is provided with and forms the circumferential antelabium 219 that extends inward into the curved surface 221 in the aperture that is formed by shoulder 6 '.In cross section (seeing Figure 16), curved surface 221 has part circular shape and the about 110 ° arc 223 of extend through.Part circular surface 221 is oriented so that described surperficial 221 radially 225 be parallel to the longitudinal axis of cylindrical wall 217 and extend.In the specific layout shown in Figure 16, the arc 223 that part circular surface 221 was scanned ends at aforementioned radially 225 places.Also will understand from the side cross-sectional view of Figure 16, the surface 227 of the external cylindrical of shoulder 6 ' radially 225 overlaps with described, and intersects and the top edge 229 of formation shoulder 6 ' with part circular surface 221.

In addition, especially with reference to Figure 16, to understand, pipe joint 22 ' is provided with the profile with shoulder 6 ' coupling so that part circular surface 221 combinations of the inner surface 216 of pipe joint 22 ' and shoulder 6 ' provide do not have convex ridge, towards the shoulder of upstream/downstream, discontinuous and/or produce the smooth surface of any further feature of the pressure loss.More particularly, the geometry of pipe joint 22 ' so that the transition part from the inner surface 216 of pipe joint 22 ' to the part circular surface 221 of shoulder 6 ' can not utilize and hinder or other pressure loss produces the flow that feature provides the surface (by on the either direction of pipe joint 22 ') through combination.Given shoulder 6 ' symmetry, no matter how pipe joint 22 ' locates with respect to angle orientation or the utmost point of housing 4 ', all keeping is this situation.

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

In practice, because 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 the inner tube joint surface 216 will not necessarily all not have discontinuous on the whole or other pressure loss produces feature.Especially, can between the part circular surface 221 of the edge 231 of pipe joint 22 ' and shoulder 6 ', there be the gap.This gap can reduce by utilizing die-casting technique to make in pipe joint 22 ' and the part circular surface 221 one or both by steel (or other metal material) in practice.

Pipe joint 22 ' is provided with the shoulder of the general cylindrical of cylindrical wall 233 forms in addition, and it has and the internal diameter of the cylindrical wall 217 of housing shoulder 6 ' and internal diameter and the external diameter that external diameter equates.When pipe joint 22 ' was positioned on the described shoulder 6 ', the cylindrical wall 233 of pipe joint 22 ' mated with one heart with the cylindrical wall 217 of housing shoulder 6 '.Crooked wall 235 extends radially outward the top edge of pipe joint cylindrical wall 233 from aforementioned inner tube joint surface edge 231.In the cross section, the shape of crooked 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 the wall 235 of bending, in order to extra rigidity is provided and prevents or reduce the bending of pipe joint 22 ' between the remainder (seeing Figure 13) of described wall 235 and pipe joint 22 ' for described wall 235.

As in the prior art separator 2, the pipe joint 22 ' of improved separator 2 ' uses traditional injection-molded or die-casting technique manufacturing, and the result has formed sharp-pointed interior turning 239 (seeing Figure 34).Can think that this turning 239 is similar to the interior turning 40 of prior art pipe joint 22.Yet, will understand, the existence on the part circular surface 221 of housing shoulder 6 ' has guaranteed that in conjunction with improved pipe joint 22 ' interior section of flow path elbow that housing 4 ' is located provides radius.As the above mentioned, this and pipe joint 22 ' are irrelevant with respect to the angular orientation of housing 4 '.Separate from the fluid of the inner surface of elbow and to be 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 ', the second end of described pipe joint (being provided with the distant place of an end of housing interface profile) is provided with tooth or sawtooth 38 ' on its outer surface, in order to grasp the flexible pipe that is positioned in use on pipe joint the second end.

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

From above will understanding, pipe joint 22 ' can be positioned at as shown in Figure 16 shoulder 6 ' upper and with this shoulder 6 ' adjacency in do not rotate with being obstructed.Therefore, pipe joint 22 ' rotatable being welded on the shoulder 6 ' is in order to be fixed to definitely housing with required angular orientation with pipe joint 22 '.The method that it will be apparent to those skilled in the art that stationary pipes joint 22 ' does not need as use threaded securing member in the prior art separator 2.Also will understand, this rotating welding technology allows pipe joint 22 ' to fix with any angular orientation with respect to housing 4 ', and whole circumferentially (perhaps closed loop) sealing is provided and does not need O-ring packing.Particularly, the heat that is produced by the frictional force that acts on during the relative rotation of housing 4 ' (that is, shoulder 6 ') and the abutment surface of pipe joint 22 ' between the described surface causes described melt surface.Then stop the rotation and described surface cure, thereby be bonded to each other.

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

Now will with reference to Figure 34 aforementioned internals be described in more detail especially.

At 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 ' that catches between the step parts 56 ' of upper steel cap member 54 ' and plastic material.Top axle bearing unit 50 ' (and also having bottom bearing unit 90 ') comprises roller bearing (as in the 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 ' (around the bottom part of cap member 54 '), and it is positioned at the cylindrical wall 60 ' (but not along side direction near it) of rotor case 4 ' in the separator 2 ' that assembles.Cylindrical wall 60 ' is from the upper inside surface of rotor case 4 ' to downward-extension.Circular convex ridge 238 is 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 (with reference to Figure 37 to 41) that will be described in more detail below, top axle bearing unit 50 ' is fixed to the upper inside surface of rotor case 4 ' by means of the rotating welding technology.Particularly, step parts 56 ' are welded on the convex ridge 238.And be not so good as with threaded securing member top axle bearing unit 50 ' to be fixed to rotor case 4 ' like that in the prior art separator 2.This layout so that the rotation of top axle bearing unit 50 ' overlap with the central axis 64 ' of rotor case 4 '.

In top axle bearing unit 50 ', provide three part circular grooves 66 ' (only having shown wherein two among Figure 34), in order to allow inlet fluid to flow through wherein (as by shown in the arrow 68 ').Upper cap member 54 ' deflection is from the inlet fluid of cage bearing 52 '.As in prior art separator 2, the downside of the topmost of cap member 54 ' part also makes the lubricating oil mist deflection (in cage bearing 52 ') of upwards advancing during use by armature spindle.

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

First group of member 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 plug-in unit 72 ' and support plate 70 ' leave rotor case 4 ' front isolation from the isolated oil of Purge gas in conjunction with working each other at isolated oil and Purge gas.Support plate 70 ' is formed from steel, and housing plug-in unit 72 ' is made by plastic material.Support plate 70 ' and housing plug-in unit 72 ' are fixed to each other by means of three threaded fasteners 74 ' (seeing Figure 29) to be gone up, and these three threaded fasteners 74 ' are threadedly engaged with the lug boss 76 ' of giving prominence to downwards from the downside of housing plug-in unit 72 '.The openend of support plate 70 ' closed rotor case 4 ', in order to the closed interior space of housing 4 ' is provided, the some members in second group of member are positioned at wherein.Thus, can think that rotor case 4 ' is the first housing parts that limits the inner space, this inner space be used for to receive for separating of material (for example, oil and gas) and the member that isolated material is directed to different outlets from described inner space.Can think that support plate 70 ' is the second housing parts that limits described inner space with the first housing parts.

In this specification, will discuss in more detail first group of member hereinafter.

Second group of member forms rotor assembly, and comprises rotating shaft 78 ', upper rotor part dish 80 ', forms fan and the turbine unit 88 ' of stacking 84 ' a plurality of independent separator disks 82 ', fan disk 240, end piece/plate 86 ', splash guard dish 242 and combination of separator disks 82 ' together.Rotating shaft 78 ' is made by metal material, and the remainder of second group aforementioned components is made and utilized the injection moulding technology manufacturing by plastic material.Second group aforementioned components goes up to be used for preventing or limit at least that mode that they relative to each other rotate is fixed to each other.In second group of member, also provide spiral compression spring (metal material), as hereinafter describing in more detail.Second group of member rotatably is installed on first group of member by means of bottom bearing unit 90 ', and rotatably is installed on the rotor case 4 ' by means of top axle bearing unit 50 ' in the separator 2 ' that assembles.

The rotor assembly that second group of member forms will be described now in more detail.

Rotating shaft 78 ' has the ring section, in order to the fluid flow path 92 ' that extends longitudinally along its whole length is provided.When using separator 2 ', this flow path 92 ' allows oily mist upwards to transmit and be delivered to the top axle bearing unit 50 ' by rotating shaft from turbine shroud, in order to lubricate the bearing of described unit 50 '.The outside of rotating shaft 78 ' is provided with some recesses and shoulder, and they help member is remained on correct axial location at rotating shaft 78 '.

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

In the situation that upper rotor part dish 80 ', separator disks 82 ' and end plate 86 ', frusto-conically shaped portion utilizes and a plurality ofly is connected to the center hub element that is associated from its spoke parts that radially extend internally.These spoke parts have the space of opening between them, pass them vertically and flow along rotating shaft 78 ' to allow fluid.

In the situation that fan disk 240, frusto-conically shaped portion 290 is connected to the center hub element 292 that is associated by means of the second frusto-conically shaped portion 294.This second frusto-conically shaped portion 294 is continuous, so that convection cell provides obstruct, and prevents thus fluid along rotating shaft 78 ' or is upward through fan disk 240 or is passed down through fan disk 240 and flows vertically.

The Frusto-conical shape of the second frusto-conically shaped portion 294 has the larger angle of angle than other frusto-conically shaped portion of improved separator 2 '.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 plug-in unit 72 ') situation (they all have identical angle) is compared, and the opposite side of the second frusto-conically shaped portion 294 is dispersed quickly/assembled.Center hub element 292 is cylindrical walls of erectting from the second frusto-conically shaped portion 294 (seeing especially Figure 26 and 33).The groove 296 that extends longitudinally (having shown wherein only one among Figure 26) provides by the whole thickness of the cylindrical wall of fan hub element 292, to be used for receiving the key 254 that radially extends from rotating shaft 78 '.By this way, prevented the rotation of fan disk 240 with respect to rotating shaft 78 '.

The downside of the first frusto-conically shaped portion 290 of fan disk 240 is provided with around the central axis of fan disk 240 isolated a plurality of joint filling part parts 298 equidistantly.Each joint filling part parts 298 are provided as the straight convex ridge of giving prominence to from the downside of the first frusto-conically shaped portion 290 downwards, and in the radially outermost edges that extends in the radial direction the first frusto-conically shaped portion 290 from the radially penetralia edge of the first frusto-conically shaped portion 290.In the separator 2 that assembles, joint filling part parts 298 are in abutting connection with the upper surface of the frusto-conically shaped portion of end plate 86 ', and guarantee thus the interval between fan disk 240 and the end plate 86 ', fluid can pass this interval (as indicated by the arrow 188 ' among Figure 34).During using separator 2 ', the fluid between fan disk 240 and the end plate 86 ' of rotating to be of joint filling part parts 298 is given and being rotatablely moved.As a result, described fluid outwards moves towards the cylindrical wall 201 of rotor case 4 '.Oil droplet (and/or, in fact entrained other liquid or the particulate pollutant of gas flow) is dished out effectively facing to the cylindrical wall 201 of rotary shell 4 ', and on to dirty (perhaps falling) to support plate 70 '.The gaseous fluid of discharging from the space between fan disk 240 and the end plate 86 ' or also to flow to support plate 70 ' downwards upper or directly leave rotor case 4 ' will be as hereinafter setting forth in more detail.

About end plate 86 ', the radially penetralia circular edge of frusto-conically shaped portion 108 ' is connected to center hub element 98 ' (seeing Figure 18) by means of a plurality of spoke parts 110 '.Yet the wall 300 of cylinder form is also from the described radially penetralia edge of frusto-conically shaped portion 108 ' to downward-extension.In the separator 2 ' that assembles, cylindrical wall 300 is 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, so that the internal diameter of cylindrical wall 300 reduces in upward direction in the separator 2 ' that assembles.The columniform outer surface of wall 300 has and the essentially identical diameter of the center port of housing plug-in unit 72 ', and in the separator 2 ' that assembles, is positioned in the described aperture, and making has minimum spacing between wall 300 and the package case 72 '.This closely cooperates, and in the counterrotating while that allows between end plate 86 ' and the package case 72 ', helps to reduce and can flow so that the amount of the isolated oil of removing pollutant gas between the center port of described wall 300 and package case 72 '.In addition, the inside fi-ustoconical surface 302 of described wall 300 works to resist the oil droplet that upwards flows and is sent in the space between fan disk 240 and the end plate 86 '.The oil droplet that it will be understood by those skilled in the art that the fi-ustoconical surface of contact wall 300 will stand to rotatablely move, and because the Frusto-conical shape on described surface stands the power of effect downwards.

Splash guard dish 242 comprises the annular disk 304 on plane, this dish 304 is connected to center hub element 308 by means of six spoke parts 306 that radially extend internally from it, and this center hub element 308 is positioned at rotating shaft 78 ' and (sees especially Figure 28) on every side in the separator 2 ' that assembles.The diameter of the center port that is limited by the annular disk 304 on plane equals the internal diameter of lower end of the cylindrical wall 300 of end plate 86 ' substantially.Therefore passing the flow that splash guard dish 242 enters the zone between fan disk 240 and the end plate 86 ' does not exist the significant pressure loss to produce feature in place, the junction surface between splash guard dish 242 and end plate 86 '.To understand, annular disk 304 provides vibrating part, this vibrating part radially extends from the lower end edge of described cylindrical wall 300, and works in use to cover any spacing between the part of the center port that the described wall 300 of restriction of the outer surface of described cylindrical wall 300 and housing plug-in unit 72 ' extends through.By this way, the annular disk 304 on plane has reduced that isolated oil droplet spatters or has otherwise moved up and pass the center port of package case 72 ' so that the possibility of removing pollutant gas from support plate 70 '.

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

The hub element 308 of splash guard dish 242 provides as cylinder, and its upper end is closed by the wall that is arranged to perpendicular to the plane of described cylindrical longitudinal axis (and, in the separator 2 ' that assembles, perpendicular to central axis 64 ').Described cylindrical internal diameter is larger than the external diameter of rotating shaft 78 ', and the wall on plane is provided with center port, and described axle 78 ' passes this center port in the separator 2 ' that assembles.This layout so that, in the separator 2 ' that assembles, the cylinder of rotating shaft 78 ' and hub element 308 limits annular space between them, this annular space receives spiral compression spring 96 ', in order to splash guard dish 242 is depressed into and end plate 86 ' adjacency, end plate 86 ' then abut against upper rotor part dish 80 ' and press 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 manufacturing, so that the cylindrical wall 300 of permission end plate 86 ' passes the center port of package case 72 ' and locates.If splash guard dish 242 is one with end plate 86 ', then this will be impossible, because the external diameter of annular disk 304 is larger than the diameter of the center port in the housing plug-in unit 72 '.

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

In addition, although the technical staff will understand separator disks 82 ' will be thinner, in order to allow in relatively short stacking 84 ', to provide the dish of larger amt, but upper rotor part dish 80 ' and end plate 86 ' are much thicker than separator disks 82 ', so that the place, two ends at dish stacking 84 ' provides rigidity, and allow thus will compress the frusto-conically shaped portion that axial force is applied to separator disks 82 ' equably by means of upper dish 80 ' and end plate 86 '.To understand, compression stress is produced by described spiral compression spring 96 ', and spiral compression spring 96 ' upwards is pressed on the downside of hub 308 of splash guard dish 242.Then the hub 308 of splashproof boot disk 242 upwards is pressed on the downside of hub 98 ' of adjacency of end plate 86 '.

Compression about the dish stacking 84 ' between upper dish 80 ' and the end plate 86 ', the technical staff will understand, as prior art separator 2, stacking 84 ' interior adjacent separator disks 82 ' must keep being spaced apart from each other, in order to allow flow to cross improved separator 2 '.This interval of separator disks 82 ' is provided in improved separator 2 ' by means of a plurality of distance pieces 246.Each distance piece 246 is that to be positioned at the upper surface 102 ' of frusto-conically shaped portion 124 ' of each separator disks 82 ' upper and from its outstanding point (seeing Figure 20).

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

In the described distance piece 246 each has round-shaped, but can use other shape (for example, can use elliptical shape).Any alternative shape that is used for distance piece 246 preferably has crooked edge, in order to reduce the fluid pressure loss in the fluid that flows through distance piece.

First group of distance piece 246 is arranged in the circle concentric and adjacent with the interior circular edge 104 ' of described upper surface 102 '.Each distance piece 246 in this first group is positioned near the part of frusto-conically shaped portion of spoke link dish 82 ' interior circular edge 104 ', its mid-game 82 '.Second group of distance piece 246 be arranged in concentric with the outer circular edge 106 ' of described upper surface 102 ' and the circle that is adjacent in.The 3rd group of distance piece 246 is arranged in the inner circular edge 104 ' and the outer circular edge 106 ' that coil 82 ' frusto-conically shaped portion concentric and large in the circle of the centre between them.

As setting forth in more detail ground hereinafter, each separator disks 82 ' (and, in fact, fan disk 240) can with respect to rotating shaft 78 ' only in three feasible positions, angle be positioned on the rotating shaft 78 ', and distance piece 246 in the location on the described upper surface 102 ' so that when dish 82 ' any that is arranged in these three positions is upper the distance piece 246 of adjacent dish 82 ' necessary aligned with each other.In other words, upper and push it to when being adjacent to each other to form aforementioned stacking 84 ' when vertically separator disks 82 ' being shifted onto rotating shaft 78 ', necessary: as (i) specifically to coil directly over the distance piece 246 that each distance piece 246 of 82 ' is located at the adjacent dish 82 ' that is positioned at described specific dish 82 ' below in stacking 84 ', and (ii) specifically coil each distance piece 246 of 82 ' and be located under the distance piece 246 of the adjacent dish 82 ' that is positioned at described specific dish 82 ' top in stacking 84 '.As a result, be applied to dish stacking 84 ' compression stress by end plate 86 ' and in the inc situation in the interval between the adjacent separator disks 82, pass through stacking 84 ' by means of the distance piece 246 of alignment.This guarantees that fluid keeps flowing 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 that is associated.This allows fluid to flow through described dish upper surface 102 ' in the mode that relatively not hindered by distance piece along circumferential direction, and radially flows through described surperficial 102 '.This guarantees the minimise loss of pressure in the flow between the adjacent dish 82 '.

In Figure 21 and 23 of accompanying drawing, shown other member isolation of upper rotor part dish 80 ' and rotating shaft 78 ' and separator 2 '.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 the described axle 78 '.This combination has prevented the relative rotation between hub 114 ' and rotating shaft 78 '.

The hub 114 ' of upper rotor part dish 80 ' extends upward vertically along rotating shaft 78 ', and ends at the upper end of described axle 78 '.The top part of rotating shaft 78 ' (the second spiral compression spring 130 ' is positioned at around it) is provided with the coating (lining) of plastic material (preferred thermoplastic) thus.This coating protection spring 130 ', and particularly protect axle 78 ' to avoid the fretting wear erosion.First group of the alternative of the first embodiment 2 ' and second group of internals show in Figure 19.Except not adjacent with the second helical spring 130 ' plastic coating of the upper end part of rotating shaft 78 ' wherein, alternative separator is identical with the first embodiment.

The hub 114 ' of upper rotor part dish 80 ' is also along rotating shaft 78 ' vertically to downward-extension, and ends at the some place directly over the bottom bearing unit 90 '.Bottom bearing unit 90 ' is the metal end of contact rotating shaft 78 ' in the separator 2 ' that assembles thus.More particularly, hub 114 ' extends along the entire depth of separator disks stacking 84 ', and the hub 120 ' of each separator disks 82 ' is separated with rotating shaft 78 '.Also will understand, hub 114 ' also provides the coating (lining) of plastic material (preferred thermoplastic) for rotating shaft 78 ' in the zone of the first spiral compression spring 96 '.In addition, this coating protection spring 96 ', and axle 78 ' are particularly avoided fretting wear and are corroded.

The frusto-conically shaped portion 112 ' of upper rotor part dish 80 ' is connected to hub 114 ' by 12 spoke parts 116 ' that radially extend.Each spoke parts 116 ' have the cross section of rectangular shape, and (little) side 310 is adjoined the radially penetralia circular edge 312 of described frusto-conically shaped portion 112 ' on it.Each spoke parts 116 ' are from described edge 312 vertically to downward-extension.This layout is so that when upper rotor part dish 80 ' rotated during use separator 2 ', each spoke parts 116 ' played the effect of fan blade, and give motion at adjacent fluid.As it will be appreciated by those skilled in the art that, the motion that is given to fluid by each spoke parts 116 ' causes fluid tangentially to flow from the circular path of spoke parts 116 ', and effectively outwards dishes out towards the cylindrical wall of rotor case 4 ' in frusto-conically shaped portion 112 ' below and through dish stacking 84 '.Spoke parts 116 ' can cause upper rotating disc 80 ' rotation as the function of fan blade, thereby by fluid intake 8 ' (as indicated by the arrow 68 ' among Figure 34) and by the space 600 between the spoke parts 116 ' with gas suction rotor case 4 ', the entrance of described space 600 expression rotor assembly thus.

The fluid that enters rotor case 4 ' passes three part circular grooves 66 ' in the top axle bearing unit 50 '.In the separator 2 ' that assembles, the spoke parts 116 ' of upper rotor part dish 80 ' be positioned at three part circular grooves 66 ' under.Special Figure 34 with reference to accompanying drawing, to see, the radial dimension of part circular groove 66 ' is less than the radial dimension (that is, length) of spoke parts 116 ', the very large part of the fluid that enters as a result, only impact at first spoke parts 116 ' be positioned at part circular groove 66 ' under length.This length of each spoke element 116 ' is provided with the from it fluid stator 314 of side (or leading edge) 310 upwardly extending bendings.The purpose of each stator 314 is to reduce or eliminate the pressure loss that is associated from separating of spoke parts 116 ' with inlet fluid.This realizes in the following way: the substantially axial stream of inlet fluid is provided in the rotor case 4 ' with stator, this stator has the cross section of aerodynamic shape, and is oriented the string that has the angle of attack (or another angle of attack that can not cause fluid to separate from stator 314) of basic zero degree about the flow that enters.

The sectional view that in Figure 22, has shown the length of passing the spoke parts 116 ' that are provided with stator 314.The surface of stator 314 works to guide the fluid near the leading edge 310 of spoke element 116 ' to align with spoke element 116 '.The string 316 that is associated with the leading edge 318 of stator 314 is oriented the angle of attack that has basic zero degree about the fluid that flows through described stator 314.This fluid-phase for the direction of stator 314 by arrow 320 expressions, and indicated such as 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 entrance flow path) axial velocity, and (ii) tangential velocity of stator 314 (ω r wherein, ω is that the upper rotor part dish is angular speed; And r is that stator is apart from the radial distance of pivot) function.Because flow depends on radial position r along stator 314 with respect to the direction 320 of stator 314, string 316 can be oriented to the angle that changes along with radial position.In other words, fluid stator 314 can be provided with and reverse, in order to guarantee that stator 314 and the flow that enters are correctly aliging along all radial positions place of stator 314.More particularly, the acute angle 322 between string 316 and the vertical datum line 324 (parallel with the central axis 64 ' in the separator 2 ' that assembles) can increase towards the most external radial position from the penetralia radial position gradually along spoke parts 116 '.

The technical staff will understand, during using improved separator 2 ', the air that enters is downward through three part circular grooves 66 ' vertically, and impact be arranged in described groove 66 ' below short distance and around central axis 64 ' on the stator 314 that circular path rotates.Because the string 316 of the leading edge 318 of each stator 314 is oriented the angle of attack that has basic zero degree with respect to the flow that enters, described flow cross the low-pressure side 324 of stator 314 and high-pressure side 326 both, and be directed and flowing with respect to the axial direction of spoke parts 116 ', and can be from stator 314 or the 116 ' separation of the spoke that is associated parts.Avoided or minimized thus by the pressure loss that the fluid that flows through upper rotor part dish 80 ' produces.

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

To notice, Figure 22 has presented stator 314 and the schematic diagram in the cross section of the spoke parts 116 ' that are associated, and not necessarily represents particularly preferred geometry or in fact be 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 radially penetralia edge 312 of frusto-conically shaped portion 112 ' and erects from this edge 311.In the separator 2 ' that assembles, rim 328 is positioned at radial outside with respect to the cylindrical wall 58 ' of giving prominence to of top axle bearing unit 50 ' downwards.Yet rim 328 is positioned at the described cylindrical wall 58 ' of next-door neighbour to be located, (perhaps significantly restriction) fluid leakage (seeing especially Figure 34) between them in order to prevent.

Three keys 254 radially extend from the hub 114 ' of upper rotor part dish 80 ', will the most easily see such as the Figure 23 from accompanying drawing.These three keys 254 are equidistantly spaced apart around the central longitudinal axis of upper rotor part dish 80 ', and the downside 330 along hub 114 ' (and therefore along rotating shaft 78 ') from spoke parts 116 ' extends to the following point along hub 114 ' vertically: the separator 2 ' that assembles, in the middle of this center hub element 292 along fan disk 240 approximately is positioned at.

Each key 254 has root portion 350 and head portion 352.Root portion 350 links with the remainder of hub 114 '.Head portion 352 adjoins root portion 350 and provides free end to key 254.The root portion 350 of each key 254 is than head portion 352 wider (that is, having larger circumferential size).Because the different in width of root portion 350 and head portion 352, the both sides that the junction surface between root portion 350 and head portion 352 is in each key 254 provide step 354.With reference to Figure 23, will see especially, the upper end to each key 254 increases the width of the root portion 350 of each key 254 from the lower end of each key 254.In addition, the width of each root portion 350 is no better than one the width (that is, circumferential size) in 12 spokes 116 ' of upper rotor part dish 80 '.The head portion 352 of each key 254 is also along circumferentially aliging with spoke parts 116 ' and adjoining 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 especially Figure 23,24 and 25) by this aperture.Therefore prevent separator hub 120 ' with respect to the rotatablely moving of upper rotor part hub 114 ' (and with respect to rotating shaft 78 ') by means of three keys 254, these three keys 254 provide and radially extend to the moon coupling profile of the correspondence that the aperture 252 of separator hub 120 ' limits vertically along the length of upper rotor part hub 114 '.This position of key 254 prevents separator hub 120 ' with respect to the side direction of rotating shaft 78 ' and rotatablely moves.More particularly, the surface 356 of the head portion 352 of each key 254 (this surface 356 is generally along radially extending) is in abutting connection with the surface 358 (this surface 358 is also generally along radially extending) of the correspondence of described coupling profile, 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 go up substantially being pressed against each other on described surperficial 356,358 the direction perpendicular to each, and owing to this reason, exist very little or do not have described surperficial 356,358 relative sliding motion, and described surperficial 356,358 division (factional) very little or that be not associated is worn and torn (it can cause increase or the undesirable relative rotation between separator disks 82 ' and the upper rotor part hub 114 ').

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 spoke parts 126 ' that radially extend.As in the separator 2 ' of prior art, spoke 126 ' (and remainder of the separator disks 82 ' that is associated) is made by plastic material relative thin and flexibly bending.Again, in the separator 2 ' such as prior art, spoke 126 ' can be resisted side direction that they stand and revolving force and can not be out of shape, and the compression stress that is produced by helical spring 96 ' is via distance piece 246 but not pass through separator disks stacking 84 ' by separator plate convergence 126.

The technical staff also will understand, and as previously discussed, the key 252 of each separator disks 82 ' and the relative geometry in aperture 252 have guaranteed that one that each separator disks 82 ' can be in position, three angles only is positioned on the rotating shaft 78 '.By means of the location of distance piece 246 with respect to aperture 252, the utmost point of the distance piece 246 of separator disks 82 ' or location, angle keep identical with respect to rotating shaft 78 ', no matter and use in the position, three angles which, and separator disks stacking 84 ' was assembled in the possibility on the rotating shaft 78 ' when the distance piece 246 that therefore, does not have adjacent separator disks 82 ' was unjustified.However, each separator disks 82 ' be provided with can with the mark of the label alignment of other dish 82 ' of dish in stacking 84 '.By this way, the dish of all in stacking 84 ' 82 ' will have identical position, angle with respect to rotating shaft 78 '.Mark provides as being positioned on the hub between two spokes 126 ' and extending radially outward short-range rib 256.

For clear, Figure 13 of accompanying drawing, 15,19,20,27,33,34 have shown the separator disks that dish stacking 84 ' exists quantity to reduce.

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 that this spring 130 ' is along the downward axially-movable of rotating shaft 78 '.In addition, in the separator 2 ' that assembles, the cage of cage bearing 52 ' in abutting connection with and to lower compression the second spring 130 ' (wherein the upper end of rotating shaft 78 ' keep and the cap member 54 ' of top axle bearing unit 50 ' between see especially Figure 34 every opening –).

During the improved separator 2 ' of assembling, except the fan of combination and turbine unit 88 ', all be connected to each other mutually in second group of internals.Upper rotor part hub 114 ' (and remainder of upper rotor part dish 80 ') is together injection-molded in position with rotating shaft 78 '.Stacking 84 ' of separator disks 82 ' then endwisely slips from its lower end edge along rotating shaft 78 ', in order to be positioned to the downside adjacency with the frusto-conically shaped portion 112 ' of upper rotor part dish 80 '.

Be installed at fan/turbine unit 88 before the lower end of rotating shaft 78, the lower end of axle 78 be positioned to be passed in first group in the internals support plate 70 and in the housing plug-in unit 72 each in the central circular aperture that provides.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 especially Fig. 8 and 10) of support plate 70.

About being applied to the compression stress of separator disks stacking 84 ', the technical staff will understand in addition, and this power is produced by spiral compression spring 96 '.During using separator 2 ', Compress Spring 96 ' is with rotating shaft 78 ' rotation, and the inner radial seat ring adjacency of the lower end of Compress Spring 96 ' and bottom bearing unit 90 ' in order to face toward its extrusion, and upwards is delivered to splash guard hub 308 with described power.Then compression stress is delivered to end plate hub 98 ' from splash guard hub 308.Splash guard 242 is interrupted owing to the frictional force (it will be understood to the effect of compression stress) between splash guard hub 308 and the end plate hub 98 ' with respect to the rotation of end plate 86 '.

Because the rigidity of end plate 86 ', compression stress are delivered to the frusto-conically shaped portion 108 ' of end plate 86 ' by described a plurality of spoke parts 110 ' that radially extend 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 116 ' that radially extend from frusto-conically shaped portion 112 '.Compression stress can be delivered to hub 114 ' from frusto-conically shaped portion 112 ' owing to the rigidity of upper rotor part dish 80 '.Upper rotor part dish 80 ' react on compression stress and upwards along the axially-movable of rotating shaft 78 ' by with rotating shaft 78 ' on prone shoulder 250 adjacency upper rotor part hub 114 ' the position and prevent.Upper rotor part dish 80 ' downwards along the axially-movable of rotating shaft 78 ' by with rotating shaft 78 ' on the position of upper rotor part hub 114 ' of 248 adjacency of annular shoulder facing up prevent.

Coiling stacking 84 ' adjacent dish 82 ' can be fixed to each other definitely alternatively and go up.This will tend to the relatively rotation place that raising coils stacking 84 ' rigidity and guarantee adjacent dish 84 ' can not change (that is, guarantee to coil distance piece 246 and keep alignment, the space in order to transmit compression stress between the adjacent dish 82 ' can be closed).Dish 82 ' can be fixed on each other and go up by welding (for example, ultra-sonic welded).

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

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

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 is upwards compression in described cavity, contacts in order to upwards fan/turbine unit 88 is biased into the inner radial seat ring of bottom bearing unit 90 '.This layout is the most apparent from Figure 30 of accompanying drawing.With reference to this figure, will understand, deflector surface 139 ' facing up is provided in the described unit 88 ', and is positioned at the radially inner side of the fan blade 140 ' of described unit 88 '.Deflector surface 139 ' is carried out the function identical with deflection packing ring 139 in the prior art separator 2, but provides integratedly with fan/turbine unit 88 ', rather than the adjoining members of separation.The inner radial of deflector surface 139 ' part upwards is pressed onto the inner race adjacency with bottom bearing unit 90 ', and this inner race is upwards pressed against on the 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, in order to allow isolated oil to be downward through bottom bearing unit 90 ' and radially outwards flow through described axially spaced-apart and enter turbine shroud.

The rotor assembly of separator 2 is rotating (seeing Figure 29 and 30) by means of the hydraulic impulse turbine by arrow 134 ' indicated direction.As in prior art separator 2 ', fan/turbine unit 88 ' comprises the Pelton impeller 136 ' with a plurality of wheel blades 138 ' that are evenly spaced apart along its periphery.When using separator 2 ', the nozzle (not shown) guiding of the jet of oil in the turbine shroud is to the periphery of Pelton impeller 136 '.More particularly, jet is along the tangential guiding through the circle of a plurality of wheel blades 138 ', so that jet enters the wheel blade with its surface in alignment.Jet flows along the described surface of the in-profile of deferring to wheel blade, and is rotated by described profile afterwards, with mobile along other surface, and discharges from wheel blade afterwards.The result is that jet makes impeller 136 ' rotation.

Fan with a plurality of blades 140 ' also forms with impeller 136 '.Blade 140 ' is close to the downside of support plate 70 ' and is positioned on the impeller 136 '.These a plurality of fan blade 140 ' also along rotating shaft 78 ' be in the roughly the same axial location in deflector surface 139 ' and bottom bearing unit 90 ' on.Fan blade 140 ' extends radially outward near bottom bearing unit 90 '.It will be understood by those skilled in the art that when turbine wheel 136 ' rotation, fan blade 140 ' is around central axis 64 ' rotation.Like this, fan blade 140 ' is dished out fluid effectively from the zone between the downside of impeller 136 ' and support plate 70 ', thereby reduce the fluid pressure in the zone of bottom bearing unit 90 ', and help to pump isolated oil by the bottom bearing unit downwards from the position of support plate 70 ' top and pump to the turbine shroud of support plate 70 ' below.

For the ease of making, impeller 136 ' is made top part 142 ' and bottom part 144 ', and is located to be pressed onto by two threaded fasteners (only having shown one of them among Figure 30 of accompanying drawing) online 146 ' and be adjacent to each other.

These a plurality of fan blade 140 ' and deflector surface 139 ' form with the top part 142 ' of fan/turbine unit 88 '.The bottom part 144 ' of fan/turbine unit 88 ' is provided with lower plate member 364, and in the separator 2 ' that assembles, lower plate member 364 is arranged in perpendicular to central axis 64 ' and strides across to the plane in the lower hole that the flow path 92 ' of rotating shaft 78 ' opens wide.However, plate member 364 is spaced apart with the described opening that leads to flow path 92 ', in order to allow fluid to flow into described opening.

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

Importantly, aperture 366 is positioned at the radial outside of the opening that leads to flow path 92 '.To understand, therefore, this layout so that the mist of oil droplet can upwards flow through aperture 366 and enter thus cavity in fan/turbine unit 88 ' from turbine shroud, and the flow path 92 ' that upwards flows through rotating shaft 78 '.Yet, also will understand from aperture 366 to flow path being flowing on the radially inside direction of 92 described opening.During using separator 2 ', fan/turbine unit 88 ' rotates in arrow 134 ' indicated direction certainly, and simultaneously the mist of oil droplet can be radially inwardly 366 flows to flow path 92 ' from the aperture, flowing through the relatively large oil of the ratio in aperture 366 will be moved along lateral by the plate member 364 of spin, and tends to be dished out by the outward opening away from flow path 92 '.For example, at inclination of vehicle or in addition so that upwards spill oil from turbine shroud by aperture 366 in order to pour in the situation that the mode of the cavity of fan/turbine 88 ' moves, for the lateral movement that the oil in the described cavity is given tends to prevent that described oil from inwardly flowing towards rotating shaft 78 '.Therefore avoided a large amount of oil undesirably upwards to flow through rotating shaft 78 ' and entered coiling stacking 84 '.

In plate member 364, provide two discharge orifice 368, in order to allow oil to get back to turbine shroud from the cavity discharging in fan/turbine unit 88 '.Discharge orifice 368 is positioned to along diameter toward each other, and forms groove in plate member 364 and the general cylindrical wall of erectting from the circular periphery of described plate member 364.The position assurance of the discharge orifice 368 in the radially most external of the turbine cavity part is discharged from fan/turbine unit 88 ' really effectively away from the dish out oil of neighboring of described cavity of rotating shaft 78 '.

Although shown that in the embodiment of Figure 29 and 30 the bottom part 144 ' of plate member 364 and fan/turbine unit 88 ' is one, but in the alternative shown in Figure 31 and 32 of accompanying drawing, end plate 364 provides as the circular discs of separating with the bottom part 144 of fan/turbine unit 88 '.With reference to Figure 31 and 32, will see, the plate member 364 of the separation of alternative be with Figure 29 and 30 in identical mode be provided with the circular discs in aperture 366.Yet alternative plate member 364 is in position with respect 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, discharge orifice 368 only is provided in the cylindrical wall of bottom part 144 ', it is arranged to concentric with the circular periphery edge of plate member 364 and extends upward from this edge.The bottom part 144 ' of fan/turbine unit 88 ' is provided with the second cylindrical wall 370 in addition, the second cylindrical wall 370 be positioned at the cavity of fan/turbine unit 88 ' and to downward-extension in order to prone annular surface is provided, can be by two threaded fasteners 362 facing to this annular surface pressing plate component 364.In prone annular surface, provide recess, in order between described cylindrical wall 370 and plate member 364, provide fluid path 372.In use, the oil that outwards flows 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 outer cylindrical wall and the plate member 364 that defines together cavity, and also be provided with in addition the other cylindrical wall 370 that plate member 364 abuts against its location, but fan/turbine unit 88 other side be similar to prior art separator 2 aspect, and with prior art separator 2 in identical mode be fixed to rotating shaft 78 '.Particularly, fan/turbine unit 88 ' is fixed to rotating shaft 78 ' by means of packing ring 133 ', and it is upper and be held in place by means of the back-up ring 132 of the peripheral recess on the outer surface that is arranged in rotating shaft 78 ' that packing ring 133 ' upwards is pressed in the bottom part 144 ' of described unit 88 '.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 to have the diameter that substantially equates with the diameter of rotor case 4 '.As in prior art separator 2 ', to such an extent as to geometry so allows support plate 70 ' to be positioned on the prone shoulder 148 ' at the lower end of rotor case 4 ' relatively.By this way, the lower open end of rotor case 4 ' is by support plate 70 ' closure.Yet in improved separator 2 ', the lower open end of rotor case 4 ' is in abutting connection with the upside of support plate 70 ' and be provided with peripheral recess 260, and this peripheral recess 260 is used for receiving O-ring packing 262 (seeing Figure 34).To understand, the second O-ring packing 262 has been guaranteed the Fluid Sealing between rotor case 4 ' and the support plate 70 '.

In addition, in the separator 2 ' that assembles, radially most external circumferential edge surface 630 (formation datum level) registration of support plate 70 ' becomes columniform inner surface 632 adjacency with the lower open end that centers on rotor case 4 '.By this way, support plate 70 ' is aligned in the final position (seeing Figure 13) of expectation along side direction with respect to rotor case 4 '.

Support plate 70 ' also is provided with the central circular aperture, and in the separator 2 ' that assembles, the central circular aperture is concentric with rotor case 4 '.In other words, in the separator 2 ' that assembles, 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 most external part of bottom bearing unit 90 ' is fixing with respect to support plate 70 '.The radially penetralia of bottom bearing unit 90 partly is positioned near the rotating shaft 78 ', but not fixed thereon.

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

Housing plug-in unit 72 ' provides as the moulded parts of the one of plastic material.Yet, when following description housing plug-in unit 72 ', will think that plug-in unit comprises four parts: the outside deflector wall 264 with Frusto-conical shape; Abutment wall 266 with columniform shape; Isolating roof parts 268 with Frusto-conical shape; And the exit portion 270 that limits described plug-in unit outlet 150 ' (seeing especially Figure 27 and 28).

The isolating roof parts 268 of housing plug-in unit 72 ' have Frusto-conical shape and are bearing on the abutment wall 266.Isolating roof parts 268 are provided with the central circular aperture, and in the separator 2 ' that assembles, this central circular aperture has the central axis that overlaps with the central axis 64 ' of rotor case 4 '.Elongated channel/recess 272 (seeing 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 its entrance 282 from recess 272 extends to the exit portion 270 (having tubular form) of housing plug-in unit 72 '.Entrance 282 is limited by the recessed circumferential part at the upper circular periphery edge 274 of isolating roof parts 268.It is relative generally along diameter with the exit portion 270 of housing plug-in unit 72 ' that entrance 282 is positioned to.The about 80 ° arc 280 of aforementioned recessed part extend through of described periphery edge 274, this arc is centered by the described central axis in housing plug-in unit aperture.In alternative, the entrance of fluid path can be limited by the recessed part of the different arc of the extend through in the described periphery edge 274 (for example between 45 ° and 110 °).In the separator 2 ' that assembles, only little distance separates isolating roof parts 268 and end plate 86 '.The result, think that the major part of the Purge gas that enters the zone 606 between isolating roof parts 268 and the end plate 86 ' does (entering) like this by aforementioned recessed part and the space between the end plate 86 ' of described periphery edge 274, only less part Purge gas flows into described zone through the remainder of described periphery edge 274.

To understand, therefore the space between whole circumferential periphery edge 274 and the end plate 86 ' provides the entrance 610 of described regional 606 between isolating roof parts 268 and the end plate 86 ', but because the part 612 of a length direction of this entrance 610 (namely, the entrance 282 of path/recess 272) part than other length direction of entrance 610 has the larger degree of depth 613 (namely, larger axial spacing between periphery edge 274 and the end plate 86 '), thus most that flows into described regional 606 Purge gas do like this by described part 612 with 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, in order to minimize the flow that passes them, and also minimizes thus oil droplet and passes passing through of they.The degree of depth of the part of remaining length direction can the larger degree of depth 613 1/10th and half between, but be preferably 1/3rd of the described larger degree of depth 613.

During using separator 2 ', the Purge gas of leaving separator disks stacking 84 ' flows downward with rotatablely moving of the spiraling inner surface along the cylindrical wall of rotor case 4 '.To understand, the Purge gas that therefore enters the aforementioned areas 606 between isolating roof parts 268 and the end plate 86 ' is tended to the rotary rotational flow of utilization centered by the central axis 64 ' of rotor case 4 ' and is moved and do like this.Yet, enter described regional 606 gas flow via entrance 282 and be directed to immediately plug-in unit outlet 150 ' by means of the sidewall 276,278 of elongated recesses 272.Think that also this guiding meeting of purge gas flow reduces the rotary rotational flow motion of Purge gas immediately after described gas enters described elongated recesses 272 via recess entrance 282.In this regard, from Figure 28 of accompanying drawing, will see, the upstream portion of elongated recesses 272 is crooked (sidewalls 276 of recess 272,278 align with the inlet fluid of eddy flow thus, minimized significantly desirable (unpressure) loss of going to press at 276,278 o'clock in order to initial assault sidewall at fluid) and straighten gradually when plug-in unit outlet 150 ' is mobile along recess 272 downstream at fluid.Think and compare with above-described prior art separator 2, the immediately minimizing meeting that enters the swirling motion in the major part of gas of cleaning in the zone between isolating roof parts 268 and the end plate 86 ' reduces the pressure loss in the fluid of this part that flows through separator 2 ' significantly.

To understand, but the Purge gas that does not flow through entrance 282 enter the zone between isolating roof parts 268 and the end plate 86 ' in other position along the periphery of isolating roof parts 268 will be tended to flow through described zone 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 the isolating roof parts 268, and is given 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 ' that assembles, the prone lower circular edge 450 (seeing Figure 27) of abutment wall 266 is in abutting connection with support plate 70 ' (places, junction surface between them).Abutment wall 266 is bearing in isolating roof parts 268 on the support plate 70 ' thus, and guarantees that isolating roof parts 268 are with respect to the correct axial location of support plate 70 '.Abutment wall 266 also is provided with a plurality of columniform lug bosses 452, and they have separately for the recess that receives threadably securing member 74 '.In the separator 2 ' that assembles, each securing member 74 ' extends to by the aperture the support plate 70 ' among in the described lug boss 452 one from the below of support plate 70 '.By this way, package case 72 ' is fixed on the support plate 70 ' definitely.

The prone lower circular edge 450 of abutment wall 266 is provided with a plurality of aperture/recesses 454 that are positioned at a plurality of positions along described edge 450.As seeing from Figure 27 and 34 especially, recess 454 provides the space between abutment wall 266 and support plate 70 ', and during the separator 2 ' that use assembles, fluid can flow through this space.Particularly, during using separator 2 ', pass a plurality of recesses 454 from the cylindrical wall of rotor case 4 ' along the isolated oil that support plate 70 ' radially inwardly flows.The part of Purge gas also radially inwardly flows through the upper surface (technical staff will understand) of support plate 70 ', and this fluid also flows through a plurality of recesses 454.This flow is by the arrow 188 ' indication among Figure 34.

Outside deflector wall 264 is from the periphery edge 274 of isolating roof parts 268 to downward-extension.Deflector wall 264 has the Frusto-conical shape of dispersing towards support plate 70 ' along downward direction from isolating roof parts 268 in the separator 2 ' that assembles.The diameter that deflector wall 264 is located in the top (and therefore, the diameter of the periphery edge 274 of isolating roof parts 268) equals the external diameter of separator disks stacking 84 ' substantially.Because the Frusto-conical shape of deflector wall 264, when moving along downward direction, 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 the rotor case 4 ' therefore on flow direction (that is, on 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 preferred 14 millimeters distance 456.Outside deflector wall 264 and this interval of rotor case 4 ' and support plate 70 ' allow isolated oil (perhaps other material that separates) 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 flow 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 a side opposite with the first flow region 606 of housing plug-in unit 72 '.

And because 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 (seeing Figure 34) of the cardinal principle annular shape with unlimited lower end.Be downward through the entrance 282 of recess 272, only upwards flow subsequently owing to the recirculation of fluid and flow into thus the possibility that described entrance 282 comes removing pollutant gas along rotor case 4 ' to such an extent as to this layout so reduces isolated oil.

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 at the lower free end of 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 the rotor case 4 '.In addition, near any recirculation of the fluid the radial outer periphery of support plate 70 ' will tend to cause isolated oil to flow into aforementioned cavity 458.For example, isolated oil can upwards flow along the radially-outer surface of columniform abutment wall 266, outwards flows along the downside of isolating roof parts 268, and then flows downward along the inner radial surface of deflector wall 264.In due course, oil may be fallen on the support plate 70 ' from cavity 458 under action of gravitation.To understand, this recirculation flow path can not cause isolated oil upwards mobile in the mode of the risk of the Purge gas that causes pollute flowing into the zone between isolating roof parts 268 and the end plate 86 '.Therefore, in case Purge gas flows through regional 606 entrances (namely towards support plate 70 ', lead to the entrance between isolating roof parts 268 and the end plate 86 '), just prevented that the gas (and by its oil droplet that carries) that any recirculation subsequently that described gas upstream returns towards described entrance causes recycling from entering described regional 606 by deflector wall 264, this can isolate gas and the described entrance (that is, keeping its separation) of described recirculation effectively.

The exit portion 270 of housing plug-in unit 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 that is used for the reception Purge gas), and extending through abutment wall 266 and outside deflector wall 264 generally along radially outer direction.To be obvious especially such as the Figure 13 and 14 from accompanying drawing, exit portion 270 be positioned on the prone edge of abutment wall 266.Therefore, in the separator 2 ' that assembles, exit portion 270 is positioned at support plate 70 ' top, so that fluid can flow below exit portion 270.Advantageously, isolated oil can flow below exit portion 270, and therefore, being not inclined to periphery edge 274 towards isolating roof parts 268 climbs on the outer surface of exit portion 270, herein, isolated oil can easily pollute the gas of the cleaning of the recess 272 that flows into housing plug-in unit 72 '.Exit portion 270 be provided with supporting member 460 at it to end free ends at a distance that recess 272 opens wide, supporting member 460 is outstanding downwards from described free-ended bottom part, so that in abutting connection with support plate 70 '.By this way, supporting member 460 helps to keep minimum spacing between support plate 70 ' and exit portion 270, but also allows support plate 70 ' to provide supporting to the free end of exit portion 270.

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

It will be appreciated by those skilled in the art that, as in the situation of prior art separator 2, support plate 70 ' (and therefore, all members in first group of member and the second group of member) remain with respect to rotor case 4 ' by means of turbine shroud and be in desired location, rotor case 4 ' and turbine shroud be fastened to go up each other after, this turbine shroud is depressed into support plate 70 ' and prone shoulder 148 ' adjacency.Support plate 70 ' is clamped between rotor case 4 ' and the turbine shroud 178 ' by means of the threaded securing member of four lug bosses 284 of extend through basically.Adjacency occurs along with threaded securing member is tightened and makes support plate 70 ' and shoulder 148 ', the result, the O-ring packing 262 that described shoulder 148 ' is located is pressed in the recess 260 that is associated, and the second spiral compression spring 130 ' is by the 50 ' compression of top axle bearing unit.

In the operation of improved separator 2 ', the nozzle (not shown) in the turbine shroud is directed to the jet of oil on the turbine wheel 136 ', so as on arrow 134 ' (seeing Figure 29 and 34) indicated direction the revolving wormgear impeller.This rotary actuation rotor assembly of turbine wheel rotates in the direction 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, jointly being called in this article rotor assembly) as a whole assembly rotary shell 4 ' in and with respect to described housing 4 ' and support plate 70 '; Housing plug-in unit 72 '; And turbine shroud rotates together.

The gas of emitting and need to being processed by separator 2 ' from motor body is introduced into separator 2 ' via the fluid intake 8 ' at the top that is arranged in rotor case 4 '.Such as the arrow 68 ' indication among Figure 34, inlet gas is along entering rotor case 4 ' with central axis the 64 ' direction parallel and conllinear, and flows through three grooves 66 ' in the top axle bearing unit 50 ' before 12 spokes 116 ' that pass upper rotor part dish 80 ' flow into the entrance 600 of rotor assembly.Rotatablely moving 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 effectively outwards dished out towards the cylindrical wall of rotor case 4.In fact, 12 spokes 116 ' are given columniform motion at inlet gas.

Inlet gas is downward through the spoke 116 ' of upper rotor part dish 80 ' and separator disks 82 ', 126 ', this gas moves along the cylindrical wall of side direction towards rotor case 4 ' via the space 602 between the adjacent separator disks 82 ', shown in the arrow 184 ' among Figure 34.By along this path, the direction of flow changes above 90 °.

To understand the outlet of the space 604 common expression rotor assembly between the radially most external circumferential edge of adjacent separator disks 82 '.

Those skilled in the art also will understand, oil droplet 186 ' tend to they move through separator disks and the cylindrical wall of the rotor case 4 ' of being dished out on the time pool together and form larger dripping.In case received by described cylindrical wall, oil droplet 186 ' just tends to advance on the support plate 70 ' downwards under action of gravitation.The most external circumferential edge of separator stacking 84 ' is inwardly spaced apart fully with respect to the cylindrical wall of rotor case 4 ', in order to allow oil droplet to advance in the clear on the 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, because the rotatablely moving of rotor assembly, the fluid pressure in the rotor case 4 ' is larger in than the zone that centers at the abutment wall 266 of housing plug-in unit 72 ' and top board parts 268 and support plate 70 ' at the peripheral edge place of support plate 70 ' and separator disks stacking 84 '.As a result, tend to exist Purge gas along the cylindrical wall of rotor case 4 ' downwards and along radially inside the flowing of support plate 70 '.This flow tends to along cylindrical wall isolated oil droplet is pushed to downwards on the support plate 70 of below, and then radially inwardly promotes it by the aperture in the abutment wall 266 of housing plug-in unit 72 ' along support plate 70 '.This gaseous fluid stream is by arrow 188 ' indication (seeing Figure 34).The central round orifice opening's edge of gaseous fluid stream in housing plug-in unit 72 ' radially moves inward the upper surface through support plate 70 '.This stream of crossing support plate 70 ' tends to towards bottom bearing unit 90 ' isolated oil droplet be 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 ' tends to reduce the static pressure in the turbine shroud (rotor case 4 ' is thereon attached during use) in the zone of bottom bearing unit 90 ', so that the suction oil droplet is by bottom bearing unit 90 '.Fan blade 140 ' then radially outwards is thrown into turbine shroud with described, and from turbine shroud, they can turn back to the engine crankshaft housing.Simultaneously, the gaseous fluid that flows through support plate 70 ' is upwards aspirated the center port of passing through package case 72 ', in order to radially pass outwards through between end plate 86 ' and the fan disk 240.Then gaseous fluid can leave rotor case 4 ' by the described columniform part 211 that flows through valve cell housing 12 ', and this part 211 is connected to housing plug-in unit 72 ' hermetically, and passes the outlet 150 ' of housing plug-in unit and rotor case outlet 10 '.

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

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

Prior art ALFDEX separator 2 or improved separator 2 ' described above can comprise for the alternative devices of rotating rotating shaft 78 ' as shown in Figure 35 of accompanying drawing.With reference to Figure 35, will see, the Pelton impeller turbine of before describing 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.Yet, as it will be understood by those skilled in the art that the electrical motor driven as shown in Figure 35 is arranged and also can use in conjunction with improved separator 2 ' described above.

With reference to Figure 35, will see, the electro-motor 380 that electrical motor driven is arranged is arranged in by means of a plurality of threaded fasteners 180 ' (Figure 35 has only shown one of them) and is fixed to housing 384 on the rotor case 4.Motor shell 384 is made of top part 386 and bottom part 388, and they utilize suitable fastening means to be fixed on each other and go up, 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 outsides undesirably leaks into the space of housing 384.By this way, electronic component (comprising printed circuit board (PCB) and/or other circuit) with can cause the material of their damage and fault is subsequently kept apart.

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

The upper end of the other separating part 394 of motor shell 384 (have substantially Frusto-conical shape) be positioned at top part 386 cylindrical wall 392 lower end and be sealed on this lower end.Sealing between cylindrical wall 392 and the frusto-conically shaped portion 394 defines closed loop shape, and provides by means of other O-ring packing 396.The lower end of frusto-conically shaped portion 394 (having the diameter larger than its upper end) abuts against bottom part 388 sealings of motor shell 384 by means of another O-ring packing 398.Sealing also defines closed loop shape.

Therefore, on a side of frusto-conically shaped portion 394, described part 394 and bottom part 388 form the space thus, and electro-motor 380 is positioned at wherein, and rotating shaft 78 " the lower end extend to wherein.On the opposite side of frusto-conically shaped portion 394, the remainder of described part 394 and top part 386 and bottom part 388 forms whole space/compartment 406 by centering on and sealing, electronics/electric member (for example, printed circuit board (PCB) 408) is contained in wherein, in order to electrical power and control signal are supplied to electro-motor 380.Compartment 406 is not only opened with respect to the outside seal of motor shell 384, but also opens with respect to the space sealing that electro-motor 380 is positioned at wherein.Therefore the contaminated oil that prevents from flowing through this space when using separator can and cause damage to them near electronics/electric member.

In addition, frusto-conically shaped portion 394 is provided with the 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 the motor shell 384, in order to allow outside that one or more electric lead (not shown)s are positioned at separator (for example, the vehicle that is used for wherein with separator is associated), to be connected to the described electric supply/control member that is contained in the compartment 406.In other words, electric lead or a plurality of electric lead can be provided with for the plug that mechanically is connected and is electrically connected with connector 412.This wire or a plurality of wire portability are used for electrical power and/or the control signal that electrical motor driven is arranged.Connector 412 is sealed on the housing 384, undesirably invades in the compartment 406 in order to prevent impurity.

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 bottom part 388 of motor shell 384.Define the aperture with the diameter that substantially equates with the inner most diameter of the stator 400 of electro-motor 380 with inner radial that cylindrical wall 392 forms the described frusto-conically shaped portion 394 of sealing.

Further about the manufacturing of improved separator 2 ', and particularly about top axle bearing unit 50 ' is assembled in the rotor case 4 ', now Figure 37 to 41 of accompanying drawing carried out reference.These figure have shown the technique that is used on such as upper/lower positions top axle bearing unit 50 ' is spun welded on the rotor case 4 ': support plate 70 ' be assembled into the lower end shoulder 148 ' of rotor case 4 ' in abutting connection with the time, this position aligns vertically with bottom bearing unit 90 '.Although the caused geometry variation of warpage by injection-molded afterwards this rotor case 4 ' of described housing 4 ' is arranged, packaging technology has still been guaranteed axially aligning of top axle bearing unit 50 ' and bottom bearing unit 90 '.

This technique is used rotary welding clamp 500, and it comprises stationary part 502 and rotatably is installed to rotor portion 504 on the stationary part 502.Stationary part 502 comprises circular discs 506, and it has the diameter that equates with support plate 70 '.To such an extent as to the geometry of circular discs 506 so allows described circular discs 506 to be positioned in the separator 2 ' that assembles with the mode and rotor case 4 ' adjacency (as shown in Figure 40) identical with support plate 70 '.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 with respect to circular discs 506 by means of the bearing assembly (not shown).

One end of axle 508 is provided with for the head 510 that receives top axle bearing unit 50 '.As concentric with the circular discs 506 of stationary part 502 and by rotor portion 504 rotations around axis centered by circular discs head 510 is provided.The diameter of head 510 equals the diameter of the inner radial surface of outstanding cylindrical wall 58 ' downwards of top axle bearing unit 50 ' substantially.By this way, the cylindrical wall 58 ' of top axle bearing unit 50 ' can be positioned at around the head 510, wherein between top axle bearing unit 50 ' and axle 508, have seldom or do not have a relative lateral movement.The protuberance 512 that relative rotary motion between top axle bearing unit 50 ' and the axle 508 is erect by 510 circular discs from the head prevents.Head 510 comprises three protuberances 512, and they are mutually the same and equidistantly spaced apart around the rotation of axle 508.Protuberance 512 has the part circular shape separately, and position and size are set in order 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 during by described groove 66 reception (seeing especially Figure 37 and 38), has substantially prevented top axle bearing unit 50 ' rotatablely moving with respect to the head 510 of axle 508.

Being provided with for rotor portion 504 being connected to motor to drive rotor portion 504 with respect to the device that rotatablely moves 514 of stationary part 502 at an end that is provided with head 501 the second end at a distance of axle 508.

Rotary welding clamp 500 has been shown in Figure 39 of accompanying drawing, and this rotary welding clamp 500 has the top axle bearing unit 50 ' that is positioned on its head 510.In the situation that top axle bearing unit 50 ' is positioned on the head 510, axle 508 and top axle bearing unit 50 ' are inserted in the rotor case 4 ', as shown in Figure 40.Circular discs 506 is positioned to the lower shoulder 148 ' in abutting connection with rotor case 4 '.More particularly, radially most external circumferential edge surface 634 (formation datum level) registration of circular discs 506 becomes and centers on columniform inner surface 632 adjacency of the lower open end of rotor case 4 '.By this way, determined the lateral register of top axle bearing unit 50 ' with respect to rotor case 4 '.Utilize the rotary welding clamp 500 that is positioned at by this way rotor case 4 ', the rotation of rotor portion 504 overlaps with the central axis 64 ' of the rotor case 4 ' of describing before.

Rotor portion 504 can be arranged in order to can move in the axial direction with respect to stationary part 502, so that top axle bearing unit 50 ' can move to the second place from primary importance, on primary importance, described bearing unit 50 ' is spaced apart with the top part of rotor case 4 ', on the second place, bearing unit 50 ' is forced into the convex ridge 238 that provides at rotor case 4 ' in abutting connection with (seeing Figure 34).During top axle bearing unit 50 ' being assembled on the rotor case 4 ', rotor case 4 ' keeps fixing, and simultaneously the circular discs 506 of stationary part 502 is positioned to lower shoulder 148 ' adjacency with rotor case 4 ', rotor portion 504 is with relatively high speed rotation, and further move in the rotor case 4 ' vertically, so as to make spin/rotation top axle bearing unit 50 ' contact with described convex ridge 238.The top axle bearing unit 50 ' of spin presses convex ridge 238 forcefully, in order to produce frictional heat, and makes thus the abutment surface melting of the plastic material of top axle bearing unit 50 ' and convex ridge 238.In convex ridge 238 extrusion bearing units 50 ', the rotatablely moving of axle 508 promptly reduced and stopped, in order 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 each other thus to be gone up.

Rotor case 4 ' can be during rotating welding technique by means of the lug boss 284 in the extend through rotor case 4 ' and extend to the threaded fastener in the columniform installing rack 516 and keep fixing (seeing Figure 40).

After top axle bearing unit 50 ' has been fixed on the rotor case 4 ', just can remove rotary welding clamp 500 from rotor case 4 '.Top axle bearing unit 50 ' keeps correctly locating and being fixed on the rotor case 4 ' thus, as shown in Figure 41 of accompanying drawing.To understand, top axle bearing unit 50 ' is positioned at the position that is in the center with respect to the lower circular shoulder 148 ' of rotor case 4 '.Therefore, when the internals of separator 2 ' was positioned at housing 4 ', support plate 70 ' had guaranteed that against the adjacency of described shoulder 148 ' bottom bearing unit 90 ' also medially locates about described shoulder 148 '.Although any warpage before of rotor case 4 ' is arranged after injection-molded, top axle bearing unit 50 ' and bottom bearing unit 90 ' be therefrom vertically alignment still.

Compare with prior art separator 2, by means of its certain module/member (seeing Figure 36) that can exchange in different separator systems, the versatility of improved separator is strengthened.The ability that rotor case 4 ' (that is, a kind of module of particular type) receives different valve cells 14 ' (that is, the module of multi-form another kind of type) has above been described.This modularization measure by multi-form given type, have for the module/member (for example, valve cell 14 ') of the same characteristic features that is connected/engages with other module/member and realize.In illustrative mode, separator system can use a kind of in the several multi-form valve cell potentially, even if because these multi-form be provided with allow in the situation that valve cell many other sides may be different also with the common feature of rotor case 4 ' coupling.The table that Figure 36 provides shown the different component/module of separator system can how to be provided with alternatively member/module or with multi-form member/module exchange.
