Abstract
A gas suction apparatus for a reciprocating compressor, including a piston having a gas flowing passage where refrigerant gas flows, being inserted in the compression space formed in a cylinder enabling linear reciprocating movement, a fixing means combined to the piston and an inertia valve inserted in the gas flowing passage of the piston movably having a moving distance restricted by the fixing means, for opening and closing the gas flowing passage moving according to the pressure difference and inertia generated by the linear reciprocating movement of the piston can minimize dead volume of a gas compression space, ease controlling of a stroke and make the suction flowing of gas smoothly by an excellent reliability of response of valve, thus to improve compression performance. The damage of the component can be also prevented by increasing structural strength, thus to improve reliability.
