Reciprocating compressor

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;
• a driving motor mounted at an one end of the reference frame and generating a linear reciprocating driving force;
• a front frame coupled to the other end 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;
• 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,
• wherein the reference frame comprises:
• base means with first and second ends, a predetermined thickness and surface area having a communication hole at its center and a plurality of connection holes radially formed around the communication hole;
• motor mounting means having the driving motor at the second end of the base means;
• and
• a plurality of separated fixing arms extended in a certain length from the first end of the base means, at the end portions of which the front frame is fixed.

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 at an one end of the reference frame and generating a linear reciprocating driving force;
• a front frame coupled to the other end 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,
• wherein the connection magnet holder includes permanent magnet mounting means formed at one end and a separate connection feet formed corresponding to a connection hole at another end thereof.

• and
• a suction valve coupled at an end portion of the piston and switching a 3′, refrigerant suction passage,
• wherein the engaging means comprises:
• a flange attachment portion formed radially extended to have a predetermined width and a circular surface area at the outer circumferential portion of the body of the piston and connection feet of the connection magnet holder contacts and supports a flange outer circumferential surface;
• a combining cover covering the connection feet of the connection magnet holder supportedly contacting the flange attachment portion and one side of a flange combining part;
• and
• an engaging screw engaging the combining cover and the connection feet with the flange combining part.
