The rotor is attached to a motor that rotates it in first and second directions and is located in a cavity. The plurality of vanes are each pivotally coupled to the rotor so as the rotor rotates, the vanes selectively push fluid from an inlet port out through an outlet port. The plurality of vanes each have an end selected from the group consisting of a lobe, no lobe, and a rod located in the lobe. Each of the plurality of vanes also includes a pivot pin configured to fit in a corresponding receptacle located in the rotor so that each of the plurality of vanes is pivotable with respect to the rotor inside the cavity. | ||||||

| A variable displacement vane oil pump for use in a vehicle powertrain includes a mechanical drive coupled to a first portion of a rotor and an electrical drive coupled to a second portion of the rotor such that the variable displacement vane pump may be driven by either or both the mechanical and electrical drives to achieve greater efficiency and control while maintaining oil pressure under all circumstances including start/stop conditions. The oil pump, when being driven by the mechanical drive only, remains coupled to the electric drive such that it rotates the motor of the electric drive to generate electricity that may be used to recharge a source of electricity such as a battery. The electric drive further includes a four phase controller for controlling the motor of the electric drive to efficiently operate the variable displacement vane oil pump without the use of a pressure relief valve. | ||||||
| 85 | Internal gear pump for a brake system | US12739609 | 2008-09-22 | US08579619B2 | 2013-11-12 | Rene Schepp; Norbert Alaze |
| The invention relates to an internal gear pump for a braking system, in the pump housing of which an inner toothed hollow wheel and a gearwheel engaging in the toothing of the hollow wheel are mounted to rotate about parallel axes. The toothing thereof defines a tapering roughly crescent-shaped pump chamber, in which a filling piece is arranged supported along the length thereof. The circumferential surfaces of the filling piece closely correspond to the head diameter of the inner toothing of the hollow wheel or the gearwheel toothing and contact in a sealing manner with several tooth crowns covered thereby. A radial supporting force acts over a longitudinal range of the filling piece for improved sealing of a circumferential surface of the filling piece against the tooth crowns supporting the circumferential surface. According to the invention, a loose fit is provided between the circumferential surfaces of the filling piece and the opposing tooth crowns of the hollow wheel and gearwheel and the play acting on the filling piece is partly eliminated by support forces acting in opposing radial directions which act on the filling piece at a distance from each other. | ||||||

| A pump for a washer system includes a housing enclosing a motor driven pump and providing first and second outlets. First and second check valves are fluidly connected to and downstream from the first and second outlets. In one example, the first and second check valves are arranged in the housing. The check valves are configured such that one of the check valves is open to provide the fluid through the one of the outlets while the other check valve is closed to block fluid through the other of the outlets. In operation, a pumping element is rotated to pump fluid through an open first check valve, with the second check valve in the closed position. Reversing rotation of the pumping element pumps fluid through an open second check valve with the first check valve in the closed position. | ||||||

| 95 | Lubrication pump for inter-axle differential | US09761724 | 2001-01-18 | US06855083B1 | 2005-02-15 | Lawrence P. Wagle; Dale Kwasniewski; James F. Ziech |
| An inter-axle differential assembly comprises an input shaft, an output shaft arranged coaxially with respect to each other, a differential gearing and a dedicated reversible lubrication pump disposed between the input and output shafts. The reversible gerotor type lubrication pump includes a rotor driven by the input shaft, and an impeller, both disposed within a pump body coupled to a side gear drivingly connected to the output shaft. Thus, the lubrication pump generates lubricant flow only during the differential action between the input shaft and the output shaft, i.e. when needed. An oil flow generated by the lubrication pump is supplied to various components of the inter-axle differential gearing through a gallery of fluid passages. | ||||||

| A progressive cavity pumping system includes a pump housing, a rotor member operatively received in the pump housing, a prime mover coupled to the rotor member for driving the rotor member in first and second directions and a controlling means for actuating the prime mover, wherein the controlling automatically causes the rotor member to be driven in the second direction after shut down or idling of the pumping system. A method of operating the pumping system includes automatically driving the rotor member in a second direction after initiating shut down or idling of the pumping system and prior to start up of the same. | ||||||
| 98 | Rotary pump | US974342 | 1997-11-19 | US6033196A | 2000-03-07 | Ronald A. Schuller; Paul J. Lutes; Joseph P. Ashurst |
| A sliding vane pump is provided with side plates disposed on opposing sides of the rotor with through holes and grooves in the side plates that cooperate with passageways disposed in the seal head and access head for providing fluid communication to the rotor bearings. As a result, the fluid being pumped is used to lubricate and cool the rotor bearings. Annular grooves disposed in the side plates provide further cooling and lubrication between the side plates and the rotor as well as between the side plates and the seal head and access head. The flow through the pump may be easily reversed by rotating the side plates 180.degree., switching flow through the passageways in the seal head and access head by plugging one passageway and opening another passageway as well as rotating the vanes 180.degree.. The reversal of the flow may be accomplished without disconnecting the companion piping, the prime mover or the electrical wiring. The side plates disposed on either side of the rotor are also interchangeable and present different wear surfaces to the rotor, depending upon the side of the rotor on which they are placed. Accordingly, the interchangeability of the side plates enables the side plates to be used on both sides of the rotor to extend the working life of the side plates. Galling between the cam and the case is avoided through the use of a tapered cam liner which limits the surface contact between the case and the cam liner. | ||||||

| A bi-directional fluid pump for providing a source of pressurized fluid. The fluid pump includes a gerotor assembly, an inlet valve system, and an outlet valve system which work cooperatively to provide pressurized fluid during two directions of rotation. | ||||||
| 100 | Reversible gerotor pump | US647359 | 1996-05-09 | US5711408A | 1998-01-27 | Joseph A. Dick |
| A reversible gerotor pump and a drivetrain subassembly including the reversible pump, wherein the pump includes inner and outer rotors located within an eccentric ring and also includes a drag spring mechanism, such as a band spring, positioned around and frictionally engaged with a portion of the outer rotor. Frictional engagement between the outer pump rotor and the band spring permits the outer pump rotor to apply a rotational force to the eccentric ring when the outer rotor reverses direction, thereby ensuring positive rotation of the eccentric ring 180.degree. upon reversal of the pump. The spring may be a split-band spring having a free diameter which is smaller than the outer diameter of the outer rotor, and the eccentric ring preferably includes an ear projecting radially inwardly and positioned between the ends of the band spring. In this manner, rotation of the outer rotor and spring causes rotation of the eccentric ring through force applied on the eccentric ring at the ear. A stop pin is provided to limit rotation of the eccentric ring to 180.degree. in either direction and, once the ring is restrained from further rotation by the stop pin, the pressure of the spring end on the ear causes the spring's diameter to slightly increase, thereby reducing wear on the outer diameter of the outer rotor. | ||||||
