RD-19,744 DUAL FLOW SINGLE CELL ROTARY COMPRESSOR CROSS REFERENCE TO RELATED APPLICATIONS Abstract of the Disclosure A rotary compressor having a frame defining a cylindrical aperture and a vane slot extending radially outwardly from the cylindrical aperture is provided. The frame also defines a first inlet port extending radially outwardly from said cylindrical aperture through the frame on one side of the vane slot. A second inlet valve extends radially outwardly from the cylindrical aperture through the frame and is situated substantially diametrically opposite the vane slot. A first check valve is situated in the first inlet port for permitting flow only radially inwardly. A vane is slidably mounted in the vane slot. Two journal bearing plates each defining a journal bearing extending axially therethrough, are situated on either side of the cylindrical aperture defining a cylindrical chamber. The second journal bearing plate further defines an outlet port extending axially through the second journal bearing plate. The outlet port is situated on the other side of the vane from the first inlet port. A second check valve is situated in the outlet port for permitting flow only from the cylindrical chamber. A shaft extends through the cylindrical chamber and is rotatably mounted in the journal bearings of the first and second journal bearing plates. The portion of the shaft situated in the cylindrical chamber has an eccentrically extending circular lobe. A piston surrounds the circular lobe and contacts a portion of the cylindrical chamber periphery and the two journal plates.
