ABSTRACT:
A suction valve for reciprocating compressor includes a fixation part, which receives a driving force of a reciprocating motor, and is fixed-combined to the front end surface of a piston performing linear reciprocal movement in the cylinder, a switching part for switching a hollow channel formed to penetrate the piston having a certain area, and a plurality of arms for connecting the switching part and the fixation part to make the switching unit behave in a certain displacement section having the fixation part as a fixed point. Receiving driving force of the reciprocating motor, the piston is bent and straighten by the pressure difference, and stress is distributed evenly in the above process, and minimizing bulking phenomenon to prevent damage of a switching part. Also, the responsiveness of the valve can be improved.
