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.

Suction valve for reciprocating compressor

A suction gas guide system () for reciprocating compressor () comprises a gas guide conduit having both ends installed on a suction pipe (SP) of a shell () and on an inner flowing passage of a piston () so as to face each other and guiding sucked gas inside the shell () to the inner flowing passage of the piston (), whereby a refrigerant gas is sucked into the gas flowing passage of the piston () through the gas guide conduit () smoothly. Accordingly, suction rate of the refrigerant gas is increased, moreover, noise and vibration generated during suction of the refrigerant gas are reduced, and therefore flow resistance for the noise and the sucked gas is reduced, whereby the reliability and efficiency of the compressor is increased. Also, the pre-heating of the gas by the motor () is prevented, and then increase of the specific volume of the gas is prevented, and thereby the efficiency of the compressor () is increased.
