動コンプレツサのシール構造。 A crank that has a compression chamber 26 on the front surface of a piston 23 that reciprocates within the cylinder 25, and has a built-in mechanism on the rear surface side of the piston 23 for converting the rotational motion of the drive shaft 11 into reciprocating motion of the piston 23. In a reciprocating compressor having a chamber 12, a first ring holding groove 62 is formed on the outer circumferential surface of the piston 23 that slides on the inner circumferential surface of the cylinder 25 on the compression chamber side. A ring-type piston ring 61 that springs outward in the radial direction is attached to the ring type piston ring 61, and a second ring holding groove 63 is formed on the outer circumferential surface of the crank chamber side. A seal structure for a reciprocating compressor is equipped with a washer type piston ring 64 whose diameter is enlarged and springs in the radial inner and outer circumferential directions.
