Abstract:
1. A reciprocating compressor, comprising: a container having a gas suction pipe and a gas discharge pipe; a frame unit disposed in the container; a reciprocating motor secured to the frame unit to generate a driving force; a piston arranged so as to perform a linear reciprocating motion with respect to a cylinder by the driving force of the reciprocating motor; a valve unit installed at the frame unit so as to discharge gas by using pressure difference generated by the linear reciprocating motion of the piston; and a front elastic member arranged on a front of the frame unit in order to support the piston elastically and prevent breakage of construction parts abutting on the piston when the piston moves over a top dead center position, wherein the front elastic member is in a solid fully compressed state and a rear elastic member pushes a spring support toward the front elastic member with an elastic force thereof when the piston reaches a top dead center position, the rear elastic member is in a solid fully compressed state and the front elastic member pushes the spring support toward the rear elastic member with an elastic force thereof when the piston reaches a bottom dead center position, and the spring support is positioned between the front elastic member and the rear elastic member.
