Abstract
A pivotal piston machine or compressor including a disc-like pivotal piston oscillating on a bearing axis, such oscillatory movement being effected by engagement of a roller-type cam follower of a crank arm driven by a crankshaft, with cam surfaces formed on the pivotal piston, and angled member for limiting the oscillating movement at opposite ends of the pivotal stroke of the piston. The angled member serves as a separating wall between two compression chambers and a delivery chamber. A pair of pivotal pistons may be arranged adjacent each other to utilize a common air intake and provide a compound piston machine.
