Abstract

The invention discloses designmeasures to improve the (volumetric) efficiency of known rotating vane-type pumps or -motors.
A control-means (12,14) is disclosed which mechanically controls the radial inward and outward movements of each vane (10) in its slot (9) in the rotor (11) during its rotation along the cylindrical inner-running-surface (2) of the housing (1) of the machine, in addition to the normal centrifugal force acting on the vanes (10).
Additional springs urging the vanes outward and appropriate wear-resisting running- and sealing inlays (42) for the vanes sliding over the housing and the endcovers are resealed as well. So are sealingrings (22) or-plates between the rotor-end faces and the endcovers. All the above measures reducing blow-by and wear.

Description

  • This invention relates to a rotating vane-pump or -motor provided with a circular-cylindrical rotor with slots in which vanes are guided slidingly, which rotor is supported eccentrically in a casing with a circular-cylindrical interior, which is closed at both ends by internally substantially plane end faces.
  • Such rotating machines are known already a long time, not only as pumps but also as pneumatic motors. Both embodiments have found a wide field of application notwithstanding the often low efficiency as a result of internal leakage and the dependency on the speed of rotation for moving the vanes outwardly in the correct time intervals and angular regions.
  • It is an object of this invention to increase the efficiency of such structures considerably while maintaining the existing advantages. By such an improvement it is possible to apply a very much wider field of applications both as pumps and as motors, to increase the applicability and suitability of the structure and it is thereby also possible to choose a more compact structure for the same purpose and output, in which it is even possible to apply wider manufacturing tolerances of the composing parts and an easier assembly.
  • To obtain this object the structure is improved acccrdinc to the invention in essence by making the movement of the vanes independentfromthe speed of rotation and by providing very good sliding seals between casing and rotor and between casing and vanes.
  • The invention will now be explained further with referen to the enclosed drawings showing by way of example several possible embodiments, in which description features and advar tages of the invention will become apparent. Fig. 1 shows an exploded view of a simple embodiment of a rotating vane- pump or -motor. The means for causing the rad movement of the vanes 10 include a cam or disc 12 on each si rigidly connected to the covers 3 of the casing 1. The slidi seal between the end faces of the rotor 8 and the covers 3 is obtained by segmental plates 22 between the vanes 10, which ; plates are supported under pressure of springs 24 in annular chambers 23 in the ends of the rotor 8. The vanes themselves are provided with slot shaped recesses along the sides directed to the inner wall of the casing, said recesses taking up resilient sealing strips 42.
  • Fig. 2 shows a partial axial section of such a structure according to the invention, in which in an open chamber 11 concentric with the rotor axis and in the ends thereof there is a separate and as such freely rotatable ring 14 between the ends of the vanes directed towards the axis, which ring provides for the control of the movement of the vanes.
  • Fig. 3 shows a similar view and section of part of the structure with a loose rotatable ring 14 as in Fig. 2, but here active in a recessed corner 18 at the ends of the sides of the vanes directed towards the axis, ring 14 being shown at a distance from its operative position in recessed parts 18
  • Fig. 4 shows a similar view and section as Figures 2 and 3, in which the vanes 10 have a recess 19 opening towards the adjacent cover of the casing and taking up the separate movablf control ring 14, which in this case controls movement of the vanes positively both outwardly and inwardly.
  • Fig. 5 shows an exploded view of the same part of a structure according to the invention in a further embodiment in which the casing cover 3 is provided with a circular hub 17 concentric with the axis of the rotor and having a separate and separately rotatable ring 14 which, in this case, is of greater axial length to engage both around this hub 17 and in the recesses 19 of the vanes 10.
  • Fig. 6 shows a diagrammatic end view of a rotor of a structure according to the invention in another embodiment in which the vanes 10 at their ends near the axis of the rotor have a widened part 20 giving a better contact with the controlmembers such as control ring 14. The vanes have inner end faces perpendicular to their radial direction so as to compensate for differences in contact angle by the eccentric position of the rotor in the casing.
  • Fig. 7 shows an end view of a rotor of a structure according to the invention, having, as in Fig. 1, separate segments 22 between the vanes 10. These segments are made of particularly wear-resistant and/or self-lubricating material and are taken up in an annular chamber in the rotor between the vanes, while they are resiliently pressed against the casing covers by springs 24.
  • Fig. 8 shows from a direction inclined with respect to the axis the end of a rotor of a structure according to the invention with a chamber with a deeper portion 11 and a shallow portion 26 outwardly thereof. A disc 25 of wear-resistant and/or self-lubricating sealing material has a central hole 28 and radial slots 27 for taking up the ends of the vanes. There may be spring means not shown such as 24 in Fig. 1 and 7 to push this disc 25 towards the adjacent casing cover, and there may be a pin 31 on the rotor in shallow chamber portion 26 engaging a hole in the disc 25 to avoid that the entire force for rotating disc 25 with the rotor should be exerted by the vanes only.
  • Fig. 9 shows the end of a rotor with an end disc 29 embodied as a cap engaging and slidingly fitting around an end part 30 of the rotor with smaller diameter. There are spring: 24 for urging this cap against the inner end face of the casing and pins 31 engaging in holes in disc 29 to keep this disc in position.
  • Fig. 10 shows an exploded view of an embodiment of the structure according to the invention with the rotor 8 having in a recessed annular part 34 at both ends an annular body ? of wear-resistant and/or self-lubricating material having radial slots 33 for taking up the ends of the vanes. In thi: case, the end covers 3 of the casing have an annular recess part 35 for taking up the outer ends of the rings 32 axiall outside the slots 33 so as to have the rings 32 fitting but being easily rotatable therein.
  • Fig. 11 shows an axial section for the movable sealing between the rotor and the casing cover, the rotor 8 having at its outer periphery a protruding annular part 37 engagi by a sliding fit in an annular chamber 38 of casing cover with interposition of wear-resistant material. This material may be resilient to give a good sealing. Instead thereof the annular chamber 38 may engage around the protruding part 37 with some clearance and this chamber 38 may be filled by grease of sufficiently high viscosity. There may be sealing material in the remainder of this end face of the rotor and at the righthand end of the rotor as indicated by 21.
  • Fig. 12 shows diagrammatically a vane 10 for a structure according to the invention in front and end view, the vane having a slot shaped recess in which three separate sealing strips are mounted with a sliding fit. These strips may be maintained in sealing contact with the cylinder wall and the casing covers under a resilient pressure.
  • Fig. 13 shows this vane 10 of Fig. 12 in section parallel to its side faces and through the slot taking up the sealing strips. The slot is indicated by 47, the side sealing strips by 42 and the outer sealing strip by 48. A spring 51 embodied as a resilient wire of leafspring is positioned in the bottom of the slot 47 to urge the sealing strips 42 and 48 outwardly. The ends of this spring are bent outwardly as at 52.
  • Fig. 14 shows in perspective an embodiment of the sealing strips indicated by 49 giving a better and uninterrupted sealing around three sides of the vane; and
  • Fig. 15 shows such a sealing strip embodiment in position on the vane 10 in a peripheral slot 47 thereof as in Fig. 13. In this case, the ends of the spring 51 are bent inwardly at 52 and are taken up in suitable small openings in the bottom of the recess 47.
  • Fig. 16 shows an embodiment of a pump according to the invention with an end cover removed and seen axially from one end. The fluid enters through inlet 7 and leaves the design through outlet 6. It is always necessary to have a sufficient running clearance between the rotor and the casing, the vanes providing for the sealing between inlet 7 and outlet 6, with their different pressures.
  • Nevertheless it cannot be avoided that more than negligible fluid-volumes are moved along by said clearance-spaces from the outletsectorto the inletsector, causing appreciable volumetric losses.
  • According to the execution as shown in Fig. 16, the invention provides between the outlet 6 and the inlet 7 for a bypass opening 53 in the pumpcasing; said bypass opening 53 is positioned such that between the outlet 6 and opening 53 and between opening 53 and inlet 7 there is at any time at least one vane. The same is true for the bypass opening 54 between inlet 7 and the outlet 6, being separated from each at any time by at least one vane. The bypass openings53 and 54 are interconnected by a pipe, hose or the like 55. Said bypass duct 55 thus forms a connection between the spaces with the smallest dead volume, as soon as this volume is separated from the outlet opening by at least one vane and still separated by at least one vane from the inlet opening and another space with lower pressure in the suction-sector of the pump which is also separated from the suction-opening and the outlet opening by at least one vane. In doing so, with the machine working as compressor, "pumping around" compressed fluid and the compressed fluid-losses due to this, as well as still further increasing losses in case the backpressure at the outlet increases, are substantially avoided. Higher compression ratios in one stage become possible as well. Should this machine act as vacuumpump, then through said bypass fluid will be sucked out from the spaces with the smallest dead volume (generally filled with fluid at atmosferic pressure) by an inactive space with reduced pressure. As a result an appreciably lower vacuum can be attained
