Abstract
A suction valve coupling structure for a reciprocating compressor is disclosed in which a piston being linearly moved in a cylinder upon receipt of driving force from an electric mechanism unit, according to which gas flows through a gas flow passage formed therein, is coupled by welding to a valve for opening and closing the gas flow passage, thereby strengthening the coupling state of the suction valve. Since the coupling structure is simplified, a dead volume is reduced and a stroke volume is increased, improving compression efficiency. A stroke control of the piston is facilitated to enable a precise control of movement of the piston. In addition, a reliability of the coupling of the suction valve can be improved.
