  • Patent number: 7331772
    Abstract: A compressor comprises a reciprocating motor disposed within a casing, for generating a driving force; a compressing unit for sucking, compressing and discharging gas by a linearly reciprocating motion of a piston connected to the reciprocating motor; a plurality of resonant springs connected to the piston, for inducing a resonant motion to the linearly reciprocating motion of the piston, wherein centers of the resonant springs are positioned at the same radius on the basis of a central axis of the piston.
    Type: Grant
    Filed: July 15, 2004
    Date of Patent: February 19, 2008

  • Patent number: 7108490
    Abstract: A reciprocating compressor includes a frame unit disposed in a container; a reciprocating motor disposed in the frame unit; a cylinder disposed in the frame unit; a piston performing a linear reciprocating motion; a valve unit installed at the front of the frame unit and the piston so as to suck/discharge gas; and a front coil spring arranged on the frame unit in order to support the linear reciprocating motion of the piston elastically and prevent breakage of construction parts abutting on the piston when the piston moves over a top dead center.

  • Patent number: 6863506
    Abstract: In a reciprocating compressor including a first frame for supporting a cylinder of a compressing unit, a second frame for supporting a side of an outer stator of a motor unit and a third frame for supporting the other side of the outer stator and an inner stator of the motor unit, wherein the motor unit is arranged between the second and third frames, they are combined with each other, and the assembly is combined with the first frame. Accordingly, a reciprocating compressor is capable of reducing a fabrication cost by eliminating precise processing of construction parts and simplifying an assembly process by constructing a reciprocating motor as one assembly and combining it with a compressing unit.

  • Patent number: 6802701
    Abstract: A suction valve assembly of a compressor includes: a piston disposed movable in a cylinder forming a compression chamber, having a suction passage for sucking a fluid and a valve seat formed at a front side thereof; a valve body contacted to the valve seat to open and close the fluid, of which a front side making a portion of the compression chamber is formed hermetical; a support rod inserted into a rear portion of the valve body and fixed at one side of the piston and supporting the valve body to be moved in a certain range; and a release preventing unit formed between the valve body and the support rod to prevent the valve body from releasing from the support rod. A guide groove inside a compression chamber is removed to prevent generation of a dead volume, thereby improving an efficiency of a compressor.
