Abstract
An oscillating piston compressor characterized by a spherically contoured piston chamber in which a wedge-shaped disk-like piston is journaled for oscillating motion on an axle journaled in the housing and coinciding with the juncture of a pair of semi-circular sectors forming the piston. A cam formed on the side of the piston opposite the pressure side, is contacted either by a rotating eccentric cam, a crankarm, or a crankpin for imparting oscillating motion to the piston to effect compressing action. A flat circular valve plate, in which intake and exhaust valves are disposed, is fixed transversely in the housing for separating the piston compression chambers from intake and delivery chambers.
