Abstract:
1. A reciprocating compressor comprising: a shell in which a suction pipe and a discharge conduit are communicated; a reciprocating motor comprising a stator which includes an inner stator and an outer stator installed inside the shell with a certain air gap, and an armature disposed in the air gap between the two stators, the armature for undergoing reciprocating movement; a compressor unit including a piston coupled to the armature of the reciprocating motor for undergoing reciprocating movement together with the armature, and having an inner flowing passage formed penetrating inside, and a cylinder supported inside of the reciprocating motor so that the piston is inserted into the cylinder slidably; a frame unit supporting the reciprocating motor and the compressor unit; a spring unit elastically supporting the armature of the reciprocating motor toward motion direction; and a suction gas guiding system including a gas guide conduit having a first end installed in the suction pipe and a second end in the inner flowing passage of the piston and guiding a sucked gas inside the shell to the inner flowing passage of the piston, and the guide conduit having a baffle unit, in which a bore of a certain size is formed.
