Abstract

See full text

A variable displacement vane pump includes, but is not limited to inlet and outlet ports in a pump body, a drive shaft rotatably mounted in the pump body, a rotor driven by the drive shaft and radially extending vanes slidably disposed in the rotor. A slide is pivotally disposed on a pivot and has a central axis eccentric to the axis of the rotor. Chambers are defined by the rotor, the vanes and the slide that are successively connected to the inlet and outlet ports. A resilient member is pivotally engaged with the slide and acts on the slide to urge the slide in one direction.
