  • Patent number: 7207785
    Abstract: A vane pump is disclosed for use with gas turbine engines that is adapted and configured to provide a failure mode similar to that of a traditional gear pump. The vane pump includes a pump housing, a cam member, a cylindrical rotor member and a mechanism for communicating a high pressure fluid from the discharge arc region to the inlet arc region when the tip surface of each vane element has experienced a predetermined amounted of wear so as to prevent pump startup. The tip surface of each vane element wears as a result the sliding contact with the circumferential surface of the pumping cavity.
    Type: Grant
    Filed: November 17, 2003
    Date of Patent: April 24, 2007
    Assignee: Goodrich Pump & Engine Control Systems, Inc.
