COMPRESSOR

PROBLEM TO BE SOLVED: To provide a compressor provided with a cylinder block having a cylinder bore, a piston reciprocating and moving in the cylinder bore, a valve plate in which an absorption hole for leading compressed fluid into the cylinder bore and a discharge hole for leading the compressed fluid in the cylinder bore outside the cylinder bore are formed, an absorption valve like a belt plate opening and closing the absorption hole, and a discharge valve like a belt plate opening and closing the discharge hole to prevent breakage of a tip of the absorption valve. SOLUTION: This compressor is provided with the cylinder block having the cylinder bore, the piston reciprocating and moving in the cylinder bore, the valve plate in which the absorption hole for leading compressed fluid into the cylinder bore and the discharge hole for leading the compressed fluid in the cylinder bore outside the cylinder bore are formed, the absorption valve like the belt plate opening and closing the absorption hole, and the discharge valve like the belt plate opening and closing the discharge hole. A recessed part is formed in a section opposing to the tip of the absorption valve of the valve plate. COPYRIGHT: (C)2005,JPO&NCIPI
