Abstract: PURPOSE:To provide a compact, light compressor with large stroke volume and a constant direction of fluid flow to improve efficiency, compared with conventional reciprocating compressors. CONSTITUTION:When a piston 17 descends and a discharge valve 28 in an upper compression chamber 20 is closed, a suction valve 27 is opened to suck refrigerant gas from a suction chamber 21 into the compression chamber 20.
