Abstract
A two stage free piston pneumatically operated air compressor having an integral and coaxial power piston, first stage piston and second stage piston. The discharge of the compressor first stage is the inlet for the compressor second stage. A piston-type throttling valve is used to control the speed of the reciprocating piston. The piston-type throttling valve is responsive to the pressure drop across a fixed orifice.
