PURPOSE: A piston for compressor is provided to maximize the lubricating effect of the contact surface of the inner surface of the cylinder bore and piston by forming a connecting groove and a circumferential groove. CONSTITUTION: The piston for compressor comprises the front cylinder block, the rear cylinder block, the front housing, the rear housing. The front cylinder block and rear cylinder block comprise the working fluid compression space. The front of the rear cylinder block and front cylinder block is combined with and the front housing and rear housing. The piston compresses the working fluid is the compression space of the front cylinder block and rear cylinder block. The columnar grooves(97,97') are formed in head units(91,91'). A plurality of through grooves(99,99') is formed in the columnar groove into the axial direction of piston. |
