Patent ID: 6860725

Claim:
In a reciprocating compressor comprising: a shell in which a suction pipe and a discharge pipe are communicated; a reciprocating motor including a stator having an inner stator and an outer stator fixed inside the shell with an air gap between them, and an armature disposed in the air gap between the two stators and undergoes reciprocating movement; a compressor unit including a piston coupled to the armature of the reciprocating motor and undergoing reciprocating movement with the armature, in which an inner flowing passage is installed penetrating inside of the piston, and a cylinder supported on outside of the reciprocating motor so that the piston is inserted into the cylinder slidably; a frame unit connecting and supporting the reciprocating motor and the compressor unit; and a spring unit elastically supporting the armature of the reciprocating motor in the motional direction; wherein a suction gas guide system including a gas guide conduit located inside the inner stator and having both ends aligned with the suction pipe and on the inner flowing passage of the piston to face each other, so as to guide the sucked gas inside the shell to the inner flowing passage of the piston is provided; wherein the gas guide conduit which is smaller than the diameter of the inner flowing passage of the piston, extends to the inner flowing passage of the piston so that at least part of the gas guide conduit overlaps the inner flowing passage of the piston.
