Abstract:
A reciprocating compressor comprising:a closed container having a suction tube and a discharge tube connected thereto; a reference frame elastically supported and mounted in the closed container, the reference frame having a base and a generally cylindrical sidewall attached to and extending from a first end of the base; a driving motor mounted on a second end of the base and outside of the generally cylindrical sidewall, the driving motor generating a linear reciprocating driving force; a front frame coupled to the generally cylindrical sidewall of the reference frame opposite the driving motor 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 magnet holder positioned penetrating the reference frame through connection holes in the base; engaging means engaging the connection magnet holder and the piston; a discharge valve assembly coupled to cover a compression space formed inside the cylinder and discharging gas; a spring positioned a radial distance from an outside surface 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.
