摘要： A variable capacity vane pump includes a pump casing having a pump chamber with an inlet and an outlet port. A pump control ring is moveable within the pump chamber to alter the capacity of the pump. A vane pump rotor is rotatably mounted within the pump control ring and includes a plurality of slidably mounted vanes engaging the inside surface of the pump control ring. First and second control chambers between the pump casing and the pump control ring are operable to receive pressurized fluid to urge the pump control ring to reduce the volumetric capacity of the pump. A return spring biases the pump ring toward a position of maximum volumetric capacity against the force of the first and second control chambers to establish an equilibrium pressure. The supply of pressurized fluid to the second control chamber may be varied to change the equilibrium pressure of the pump.

摘要： In a traditional variable-displacement vane pump, at lower speeds the pump will often operate at a higher capacity than necessary for that speed, thus wasting energy. A variable capacity vane pump (20) is provided having a pump control ring (44) that is moveable to alter the capacity of the pump (20). A control chamber (60) is formed between the pump casing (22) and the control ring (44). The control chamber (60) is operable to receive pressurized fluid to create a force to move the control ring (44) to reduce the volumetric capacity of the pump (20). A primary return spring (56) acts between the control ring (44) and the casing (22) to bias the control ring (44) towards a position of maximum volumetric capacity. A secondary return spring (62) is mounted in the casing (22) and is configured to engage the control ring (44) after the control ring (44) has moved a predetermined amount. The secondary return spring (62) biases the control ring (44) towards a position of maximum volumetric capacity. The secondary return spring (62) acts against the force of the control chamber (60) to establish a second equilibrium pressure.

摘要： A variable capacity gerotor pump includes an inner rotor that is axially displaceable with respect to the outer rotor to vary the volumetric capacity of the pump. An active piston abuts the lower surface of the inner rotor and can ride inside the outer rotor, as the inner rotor is axially displaced, to provide the necessary scaling of the lower surface of the inner rotor with respect to the outer rotor. A passive piston, against which a return spring acts, abuts the upper surface of the inner rotor to provide the necessary sealing of the upper surface of the inner rotor with respect to the outer rotor. In an embodiment, a control chamber, supplied with pressurized working fluid, generates a force acting against the force of the return spring to move the inner rotor to reduce the volumetric capacity of the pump. In another embodiment, a control mechanism, such as an electric solenoid or mechanical mechanism, acts on the control piston against the force of the return spring.

摘要： A pump system includes a fixed or variable capacity pump and a speed-related control mechanism to alter the capacity of a variable capacity pump or to alter the relief pressure of a fixed capacity pump in response to changes in the operating speed of the pump. A pressure generator comprising a volume of working fluid is rotated at a speed related to the operating speed of the pump and creates a forced vortex in the working fluid. The pressure induced in the working fluid of the forced vortex is used as a speed related control to alter the discharge pressure of the pump as desired.
