ABSTRACT:
In a reciprocating compressor including a piston slide-inserted into the compression space of the cylinder, having a gas path therein, inducing a fluid into the compression space through the gas path and varying a volume of the compression space while performing a linear reciprocating motion with a mover of a reciprocating motor; a suction valve combined with the front end of the piston detachably and adjusting suctioning of the fluid into the compression space; and a discharge valve combined with the front end of the piston detachably and opening/closing the compression space of the cylinder in the linear reciprocating motion of the piston, a suction valve assembly of a reciprocating compressor includes an elastic member for absorb impact of the suction valve in clash and a combining member consisting of a head portion having a width so as to be overlapped with part of an opening/closing portion of the suction valve or a retainer and a valve seat, and accordingly a reliability of the compressor can be improved.
