【発明の名称】往復動式圧縮機
Document Type and Number:
Japanese Patent JP2795614
Kind Code:
B2
Abstract:
A compressor includes a reciprocating piston mounted in a cylinder for sucking-in refrigerant gas during a retraction stroke and then compressing and discharging the gas during a compression stroke. A front wall of the piston includes a through-hole, and carries a spring-biased closure for closing the through-hole. The closure can be opened counter to the spring force by the presence of an excessive pressure in front of the piston, in order to relieve that pressure. The closure projects forwardly beyond the piston front wall so as to also open the through-hole upon contacting an end plate of the cylinder during a compression stroke.
