  • Axial vane pump with non-rotating vanes
    Patent number: 4047859
    Abstract: A vane pump has a cam member carried upon a drive shaft in coaxial relationship therewith. The axial sides of the cam member define annular cam surfaces which each engage an array of vanes disposed in a fixedly mounted stator. An interior portion of the drive shaft is hollowed to provide a fluid inlet to passages in the cam member which communicate with the cam surfaces. The cam member is provided with additional passages to receive discharge flow from intervane volumes and direct such flow to the radially outer periphery of the cam member.
