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.
