Abstract
In a suction valve apparatus of a reciprocating compressor including a piston having a gas passage at which gas flows inside its body portion, a valve seat formed at an end of a piston body to open the gas passage and a step face formed so as to have a thickness inward from the valve seat and have a plurality of gas through holes and a mounting through hole, and a valve cone having a detachable coupling portion formed extendely from a cone portion corresponded to the valve seat of the piston and inserted into the mounting through hole of the step face of the piston so as to be movable, a re-expansion loss can be reduced by minimizing a dead volume of a suction gas valve, an efficiency of a reciprocating compressor can improve by reducing a heat transmission loss by sucking refrigerant gas through the plurality of gas through holes of the step face from the gas passage. In addition, the number of parts can be reduced and its structure can be simplified, accordingly it is advantageous to a mass-production as well as heightening the assembly productivity.
