ABSTRACT:
A rotary compressor for use in air conditioning or the like including a housing having a chamber with a cylindrical rotor journaled therein, the rotor having a set of vanes radially slidable to define enclosed compartments between them. The curved outer wall of chamber has a reference region separating the chamber into inlet and outlet sides having inlet and outlet ports in straddling relation. The rotor has its axis laterally offset from the chamber axis to produce sealing at the reference region. The curved wall of the chamber on the inlet side is of substantially elliptical profile with the major axis of the ellipse generally centered on the inlet side and with the inlet port extending to a point of cut-off short of the major axis. The curved wall on the outlet side is smoothly continuous and substantially circular in profile. In operation, gas entering the inlet port is charged in a compartment between a pair of vanes at the major elliptical axis and progressively compressed over an arc of compression greater than about 180 degrees for discharge from the outlet port in the compressed state. The outlet port is provided with a circular liner the trailing end of which defines the point of initial discharge from the outlet port, the liner being peripherally shiftable to vary the pressure at which the gas is discharged.
