ABSTRACT:
In a rotary vane hermetic compressor an improved loading structure is provided for the vanes. A pressure reducing means incorporated into the compressor rotor reduces the frictional loading of the vane tips against the compressor walls. A passageway vents fluid at suction pressure into a cavity in the rotor containing the inner tips of the sliding vanes.
