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.
Claims3
