Abstract

A variable displacement pump having an inner rotor (gerotor) and an outer rotor is disclosed. Advantageously, the pump provides a movable outer rotor capable of changing the amount of fluid transferred from an inlet to an outlet. Optionally, a biasing member is connected to the outer rotor for preventing movement of the outer rotor below a predetermined amount of pressure at the outlet.
