Definitions

  • the present invention is related, generally, to pneumatic and hydraulic pumps, motors and heat regenerative systems.
  • rotary vane pump assemblies are positive displacement pumps that include one or more vanes that are mounted to a rotor which is rotatable within a housing having an inner wall defining an open chamber. A pressure differential is applied across the vane, which causes the rotor to rotate within the open chamber of the housing.
  • the rotor is coupled with an output shaft which may be attached to any suitable machine including, for example, an electric generator.
  • it is important to maintain a fluid-tight seal between the vane and the inner wall of the housing in order to optimize efficiency and maximize power output.
  • Rotary vane pumps that use this approach generally include two or more vanes, and a spring is disposed between the rotor and each vane to bias the respective vane in a radially outward direction and against this housing.
  • the biasing forces exerted by the springs maintain the vanes in continuous contact with the housing through a full 360 degrees of rotation of the rotor within the open chamber of the housing.
  • Another approach to maintaining the fluid-tight seal between the vane and the housing is to provide open chamber with a non-circular shaped cross-section.
  • the rotor is centered within the non-circular open chamber, and a vane extends through the rotor to engage at either end with an inner wall of the open chamber.
  • the noncircularly shaped cross-section of the open chamber guides the vane through a reciprocating motion back and forth across the rotor to maintain both ends of the vane in contact with the inner wall to establish the fluid tight seals.

  • a rotor is rotatably disposed in the open chamber and has a circular shape when viewed in cross section.
  • a first pair of vanes are received in the rotor and are operably connected with one another by a first bell crank which is pivotable about a pivot axis such that movement of one vane inwardly into the rotor causes the other vane to move outwardly out of the rotor to maintain both vanes in contact with the inner wall as the rotor rotates relative to the housing during operation of the vane pump assembly.
  • the vane pump assembly constructed according to this aspect of the present invention allows for improved efficiency and cost effectiveness as compared to other known vane pump assemblies.
  • the bell crank includes a pair of resiliently deflectable arms which are made of a resiliently deflectable material such that the arms elastically deflect while the vanes move into and out of the rotor during operation of the vane pump assembly.
  • the bell crank is made as a single piece.
  • each of the arms of the bell crank has an end with a socket, and each of the vanes has a ball-shaped end portion that is received in one of the sockets.
  • the vane pump assembly further includes a second pair of vanes that are received in the rotor and are operably connected with one another by a second bell crank.
  • the vanes are uniformly spaced from one another around the rotor.
  • the rotor has a pair of slots on opposite sides of each of the vanes, and sealing elements are disposed in the slots for sealing the vanes with the rotor.
  • a bearing block and a bearing pin are received in each of the slots with the bearing pins being rotatable relative to the bearing blocks such that the bearing pins roll in response to movement of the associated one of the vanes into and out of the rotor.
  • a leaf spring is disposed in one of the slots associated with each of the vanes. The leaf spring biases one of the bearing pins against the associated one of the vanes.
  • pins operably connect the vanes of the first pair of vanes with the first bell crank.
  • an end plate body is secured with the housing.
  • a stabilizer plate contacts and seals against an end face of the rotor.
  • a biasing mechanism biases the stabilizer plate against the end face of the rotor.
  • the biasing mechanism includes a plurality of set screws which are moveable into and out of the end plate body.
  • the biasing mechanism further includes a plurality of springs between the set screws and the stabilizer plate.

  • the vane pump assembly 20 includes a housing 22 with an inner wall 24 which defines an open chamber that is generally elliptical, or oval, in shape when viewed in cross-section.
  • the exemplary housing 22 has a total of four ports 26, 28 with two of them being fluid inlet ports 26 for conveying a fluid, such as steam, into the open chamber and two of them being fluid outlet ports 28 for dispensing the fluid out of the open chamber. Although two of each are shown in the exemplary embodiment, it should be appreciated that the housing 22 could be configured with any suitable number of inlet and outlet ports 26, 28.
  • the vane pump assembly 20 further includes a rotor 30 which is generally circular in shape and is centered within the elliptical open chamber of the housing 22.
  • the rotor 30 is rotatable within the open chamber about an axis A, which is centrally located within the elliptical open chamber and the circular rotor 30.
  • the rotor 30 is coupled with an axially extending input/output shaft 32 which may be fixed with the rotor 30 through any suitable means such that rotation of the rotor 30 relative to the housing 22 drives rotation of the shaft 32 and vice versa.
  • the shaft 32 may be attached to any suitable power receiving device (not shown) for operating the vane pump assembly 20 to generate power.
  • the shaft 32 may be attached to a power source for operating the vane pump assembly 20 as a fluid compressor.
  • the exemplary embodiment of the rotor 30 has a total of four radially extending passages which are generally evenly spaced from one around the rotor 30.
  • a vane 34 is received in each of the passages and is movable radially into and out of the respective passage for sealing against the inner wall 24 of the housing 22 to establish a total of four evenly distributed, circumferentially spaced and fluid-tight seals between the rotor 30 and the housing 22.
  • Each of the vanes 34 has an end with a first U-shaped opening which opens in a radially outward direction (away from the axis A) and within which a primary roller 36 is positioned.
  • the primary rollers 36 have outer diameters which are similar to the widths of the first U-shaped openings.
  • the housing 22 presents a pair of axially extending openings 38 which are diametrically opposed with one another and are located circumferentially between the inlet ports 26 and the outlet ports 28.
  • the axially extending openings 38 are separated from the inner passage by thin and flexible portions 40 of the inner wall 24.
  • a bar 42 is positioned in one or both of the openings 38, and the bar 42 is in contact with a plurality of set screws 44 which are accessible from outside of the housing 22.
  • the radial position of the bar 42 is adjustable by threading the set screws 44 into and out of the housing 22 to manually increase or decrease a biasing force of the thin portion 40 of the inner wall 24 against the rotor 30. This allows for easy adjustment to optimize the seal between the inner wall 24 of the housing 22 and the rotor 30 and the friction between the rotor 30 and the inner wall 24 of the housing 22.
  • the vane pump assembly 20 further includes a pair of pressure balanced end plate assemblies which are joined with opposite axial ends of the housing 22 to seal the housing 22 against axial end faces of the rotor 30.
  • Each of the end plate assemblies includes an end plate body 46 with an axially extending shaft opening that has a shaft bearing 48 disposed therein for receiving the input/output shaft 32.
  • a shaft seal 50 is also disposed in the shaft opening for establishing a fluid tight seal between the end plate body 46 and the shaft 32.
  • the end plate assemblies also include a plurality of circumferentially spaced bolts for fixing the end plate body 46 with the axial end faces of the housing 22.
  • Each end plate assembly further includes a rigid stabilizer plate 52 with an annular shape which extends around the shaft opening. The stabilizer plate 52 is disposed in a groove of the end plate body 46 and has a thin and flexible membrane which faces away from the end plate body 46 for sealing against an axial end face of the rotor 30.
  • Each end plate assembly additionally includes an adjustable biasing mechanism for applying a biasing force against the stabilizer plate 52 to bias the membrane against the axial end face of the rotor 30 and establish a fluid-tight seal therebetween.
  • the biasing mechanism includes a plurality of circumferentially spaced set screws 54 which are threadedly disposed in holes within the end plate body 46 and are movable in the axial direction by threading the set screws 54 into or out of the holes.
  • a compression spring 56 is positioned between each set screw 54 and the stabilizer plate 52 for applying a biasing force against the stabilizer plate 52.
  • the magnitude of the biasing force is adjustable by threading and unthreading the set screws 54 into and out of the holes. The adjustability of the biasing force allows for the optimization of the fluid tight seal and friction between the stabilizing plate 52 and the rotor 30.
  • a high pressure fluid enters the inner chamber through the inlet ports 26.
  • Pressure differentials within the inner chamber of the housing 22 and across the vanes 34 has the effect of rotating the rotor 30 and driving rotation of the shaft 32.
  • the shaft 32 is driven by an external source to rotate the rotor 30 relative to the housing 22.
  • the movement of the vanes 34 creates a pressure differential such that the pressure which leaves the inner chamber through the outlet ports 28 has a greater pressure than the fluid which enters the inner chamber through the inlet ports 26.
  • Pairs of the vanes 34 are operably connected with one another by a bell crank
  • Each of the bell cranks 58 is made as a single piece and is generally V-shaped with a pair of arms 62 that extend away from the fulcrum pin 60 to engage the pair of vanes 34.
  • the arms 62 are angled relative to one another by approximately ninety degrees (90°).

  • the bell cranks 58 function to connect and influence the movement of the vanes 34 by harnessing a radially inward force from one vane 34 and transforming that force into a radially outward force on the other vane 34.
  • the ends of the arms 62 are connected with the ends of the vanes 34 via cylindrically-shaped pins to establish a pivoting relationship between each vane 34 and the associated arm 62.
