Abstract
Reciprocating type compressor which includes a cylinder having an inner bore, a piston reciprocating in the inner bore, an inter cooler adjacent a compression space which is formed in the inner bore by the piston and an operational gas passage and a refrigerant passage arranged in heat-exchanging relationship. An inlet valve is located adjacent to the compression space for controlling the introduction of operational gas in response to an intake stroke of the piston, and an outlet valve is arranged adjacent to the inter cooler so as to discharge the operational gas via the inter cooler in response to a discharge stroke of the piston. The refrigerant passage is ring-shaped and defines a longitudinal axis coinciding with an axial center of the inner bore. The operational gas passage includes a plurality of conduits for conducting operational gas from the compression space. The conduits include inlet ends disposed opposite the compression space and outlet ends disposed opposite the outlet valve.
