Abstract
A gas compression apparatus for a reciprocating compressor includes a reciprocating motor generating a linear reciprocal driving force, a compressing cylinder positioned within a predetermined distance from the reciprocating motor, a position controlling cylinder positioned within a predetermined distance from the compressing cylinder, an initial position variable type piston inserted into the compressing cylinder and the position controlling cylinder, and being linearly and reciprocally moved within the compressing cylinder and the position controlling cylinder, and a pressure controlling valve controlling a pressure inside the position controlling cylinder with the pressure of the gas discharged from the discharge chamber. The gas compression amount can be controlled by controlling the stroke distance of the initial position variable type piston according to the voltage control of the motor, an efficiency of the system can be heightened by preventing a refrigerant gas compression loss, and an efficiency of the compressor can be improved.
