HERMETIC COMPRESSOR AND REFRIGERATING CYCLE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a hermetic compressor increased in efficiency and reduced in vibration by reducing the fitting resistance of a flow passage resistance and the fitting resistance between a valve plate and a suction valve. SOLUTION: A suction valve 125 installed in a compression mechanism part 120 is so installed on the compression chamber 121a of a valve plate 123 as to cover a suction hole 123a. The suction valve has a hole part 125a formed between the end part P of the suction valve 125 and the suction hole 123a of the valve plate 123. A recess 124 having a depth L in the radial direction and a depth H from the valve plate 123 is formed in the inner wall surface of a cylinder 121. The end part P of the suction valve 125 is disposed in the recess. When defining the area of the hole part 125a as S, the requirement of S≥L×H is satisfied. COPYRIGHT: (C)2008,JPO&INPIT
