のピストン構造。[Claims for Utility Model Registration] (1) A piston body 3 reciprocably provided in the bore 2 of the cylinder 1, a plurality of ring grooves 4 formed on the outer peripheral surface of the piston body 3, and a ring groove 4 formed on the outer peripheral surface of the piston body 3; The compression rings fitted into the grooves 4 are connected at one end to the inner surface of the crown section 6 of the piston body 3 by caulking a spherical bearing section 7, and at the other end are connected to the drive source for reciprocating movement. In the compressor piston, a pair of ring grooves 4 are formed, and one ring groove 4 has a first compression ring 21 whose tip opens radially outward when the piston main body 3 moves forward. A second compression ring 22 whose tip opens radially outward during backward movement is provided in the other ring groove 4, and the ring groove 4 of the first compression ring 21 and the spherical bearing portion 7 are connected to each other. The piston structure of the compressor is formed by communicating with the lubricating oil communication passage 24. (2) The lubricating oil passage 24 connects the ring groove 4 of the second compression ring 22 and the spherical bearing portion 7.
A piston structure for a compressor according to claim 1, which has an auxiliary lubricating oil communication passage 24a communicating with the above.
