OSCILLATING PISTON-TYPE COMPRESSOR

In two compression units (41, 51) of a compressor, phases of respective pistons (45, 55) are configured to be opposite to each other. The piston (45, 55) has a non-circular outer peripheral surface, whereas a cylinder chamber (60, 70) has an inner peripheral surface of which shape is determined base...

Zusammenfassung:	In two compression units (41, 51) of a compressor, phases of respective pistons (45, 55) are configured to be opposite to each other. The piston (45, 55) has a non-circular outer peripheral surface, whereas a cylinder chamber (60, 70) has an inner peripheral surface of which shape is determined based on an envelope of the outer peripheral surface of the piston (45, 55) in rotation. The compressor includes an introduction section (67, 68, 163a, 164a) configured to introduce an intermediate-pressure refrigerant into a compression chamber (75) of the compression unit (41, 51).
