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.
