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.

Rotary compressor vane with built-in spring

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.

Rotary vane compressor with improved vane extension means

A rotary sliding vane compressor having means for biasing the vanes outwardly. Such means include a resilient element of improved design located in the lower portion of the vane slot and engaging a convexly shaped edge on the vane. The flexing action of the resilient member ensures that the vanes will be moved outwardly during the expansion phase of rotor travel.
