  • Rotary compressor vane with built-in spring
    Patent number: 4072452
    Abstract: A rotary sliding vane compressor having means for biasing the vanes outwardly. Such means include an elastomeric element fastened to the radially inward edge of the vane and means for applying tensile stress to stretch the elastomeric element responsive to a radially inward movement of the vane. The restoring force provided by stretching the elastomeric element in tension ensures that the vanes will be moved outwardly during the expansion phase of rotor travel.
    Type: Grant
    Filed: July 27, 1976
    Date of Patent: February 7, 1978
    Assignee: Borg-Warner Corporation

  • Rotary vane compressor with improved vane extension means
    Patent number: 4032270
    Abstract: A rotary sliding vane compressor having means for biasing the vanes outwardly. Such means include a resilient element located in the lower portion of the vane slot and engaging a convexly shaped edge on the vane. An improved wear surface on the resilient element at the area of contact with the vane slot provides enhanced service life. The flexing action of the resilient member ensures that the vanes will be moved outwardly during the expansion phase of rotor travel.
