COMPACT ROTARY COMPRESSOR WITH CARBON DIOXIDE AS WORKING FLUID

摘要

A rotary compressor assembly comprises a motor having a stator and a rotor disposed directly adjacent the stator. The rotor has an inner surface that forms a substantially cylindrical compression chamber having an axis. A first plate and a second plate are fixed relative to the rotor and define opposite ends of the compression chamber. A stationary shaft extends axially through the compression chamber. A roller is rotatably mounted on the stationary shaft and is disposed within the compression chamber. A vane has an outer radial end fixed to the rotor and extends radially inwardly. The vane is fixed to the first and second plates proximate a radial inner end of the vane. The roller defines a slot. The radial inner end of the vane is disposed within the slot. Rotation of the rotor rotates the first and second plates and the vane. Rotation of the vane drivingly rotates the roller. The vane and the roller are relatively slidable.
