  • Dual cylinder apparatus for reciprocal hermetic compressor
    Patent number: 6733257
    Abstract: A dual cylinder apparatus for a reciprocal hermetic compressor with a cylinder body having two open ends. A pair of valve plate units are disposed at both ends of the cylinder body, and have refrigerant discharge holes formed therein. A pair of pistons are movably disposed in the cylinder body and reciprocate therein. A piston bar having one end connected to a connecting rod is slidably supported on the valve plate units and reciprocate thereon while supporting the pistons. The piston bar has a refrigerant discharge hole through which a refrigerant, located in between the pistons, is discharged outside the cylinder body. A discharge valve movably disposed between the pistons opens one gap between one of the pistons and the cylinder body and closes a second gap between the other piston and the cylinder body.
