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: The present invention is a multiple stage variable displacement vane pump comprising a pressure regulating spring guide. A first spring and a second spring may be controlled by said pressure regulating spring guide. The present invention does not require a solenoid or electronic control. Control of flow and speed is achieved through operable of the pressure regulating spring guide that causes the first spring and second spring to be operable in relation to one another, but for the first spring and the second spring to be operable independently of each other. The springs may be positioned to be inline in relation to each other. Rotation of a slide and pressure exerted thereby upon the pressure regulating spring guide may create a first spring regulation stage and a second spring regulation stage.
