Abstract: 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 shaft is coupled at one end to the control ring and a second end of the shaft is positioned a predetermined distance from the casing (22). A secondary return spring (62) is mounted about the shaft 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.

Abstract: A variable displacement variable pressure vane pump system provides lubrication oil to a mechanical system. The system has a first control mechanism, which can be a control chamber directly acting on the control slider or a control chamber and control cylinder which acts on the control slider and a second control mechanism which is a control chamber and control cylinder which acts on the control slider. A control valve, operated by an engine control unit or other suitable control mechanism, selectively provides pressurized lubrication oil to the second control mechanism to allow the output of the pump system to more closely match the requirements of the mechanical system.

Abstract: A variable capacity pump includes a control ring moveable within a pump chamber to alter the volumetric capacity of the pump. First and second control chambers individually receive pressurized fluid to create forces to bias the control ring in a predetermined direction. A return spring urges the control ring toward a maximum volumetric capacity pump position. The control ring connects and disconnects the second control chamber from a source of pressurized fluid based on a position of the control ring. Forces from the control chambers and the spring act in combination with one another or against one another and against the spring force to establish first and second equilibrium pressures based on a pressurized or vented condition of the second control chamber.

Abstract: A variable capacity vane pump for an automobile includes a pump control ring positioned within the housing to move about a pivot. A rotor is positioned within a cavity of the control ring such that a position of the control ring determines an offset between a center of the cavity and an axis of rotation of the rotor. A first control chamber is provided between the pump housing and a first outer surface of the control ring. The first outer surface is positioned on an opposite side of the control ring as the working fluid chambers within the cavity. A second control chamber is provided between the pump housing and a second outer surface of the control ring. A return spring biases the control ring toward a position of maximum volumetric capacity against the forces created by the pressurized fluid within the first and second control chambers.

Abstract: A variable capacity vane pump includes a first control chamber between a pump casing and a first portion of a pump control ring. The first portion of the control ring circumferentially extends on either side of a pivot pin. A second control chamber is provided between the pump casing and a second portion of the pump control ring. The first and second control chambers are operable to receive pressurized fluid to create a force to move 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.
