Reciprocating compressor

Abstract

A reciprocating compressor includes: a closed container having a suction tube and a discharge tube; a reference frame elastically supported and mounted in the closed container; a driving motor mounted at one side of the reference frame and generating a linear reciprocating driving force; a front frame coupled to the other side of the reference frame and having a cylinder insertion hole therein; a cylinder inserted into the cylinder insertion hole formed at a central portion of the front frame; a piston inserted in the cylinder to suck, compress and discharge a refrigerant gas; a connection type magnet holder positioned penetrating the reference frame; an engaging portion engaging the connection type magnet holder and the piston; a discharge valve assembly coupled to cover a compression space formed inside the cylinder and discharging gas; a spring position at both sides of the piston and elastically supporting a motion of the piston; and a suction valve coupled at an end portion of the piston and switching a refrigerant suction passage. Thus, the operation mechanism is stable without any driving imbalance. In addition, since the relative movement between parts, that is, portions where sliding contact occurs is less created, so that a frictional loss and a loss according to the driving are reduced and the noise is less generated. Thus, a stable and reliable operation can be performed.
