Abstract
A swing-type reciprocative compressor is capable of maintaining long durability and preventing propagation of heat to the large end portion of a piston, even under high-compression. In the reciprocative compressor having a swing-type piston mechanism, a piston ring is attached to a piston ring groove to seal between a piston and a cylinder. A ring groove is provided separately from the piston ring groove on the outer circumferential side of the piston and on the crankshaft side of the piston ring groove. A guide ring restricted from moving in a radial direction and shaped like a skirt opening toward the crankshaft side is provided in the ring groove.
