Abstract:
A gas suction apparatus for a reciprocating compressor, comprising: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; an inertia valve; and fixing means combined to the piston for restricting reciprocating motion of the inertia valve, the inertia valve including: a valve cone portion formed to have a larger area than the cross section of the gas flowing passage and a certain thickness, for opening and closing the gas flowing passage, being contacted on the end surface of the piston or separated; a valve body portion extended having a smaller outer diameter than the inner diameter of the gas flowing passage at the center of the one side surface of the valve cone portion and inserted in the gas flowing passage; a plurality of guide members extended to have a certain length on the outer circumferential surface of the valve body portion and contacted on the inner circumferential surface of the gas flowing passage; and a guide hole formed to have a certain width and length in the valve body portion having the fixing means inserted in the inertia valve.
