  • Reciprocating motor and a reciprocating compressor having the same
    Patent number: 8277204
    Abstract: A reciprocating motor and a reciprocating compressor having the same are provided. One side of each of outer and inner cores forming a stator are connected to each other, to prevent a magnetic flux generated by the coil and a magnet from leaking out of the stator. Hence, it is possible to fabricate components of the reciprocating compressor employing such a reciprocating motor by using a relatively low-cost magnetic substance, resulting in a decrease in fabricating costs of the compressor. Also, a length of the magnet may be reduced, which results in a reduction of the cost for the magnet, thereby decreasing fabricating costs of the reciprocating motor and the reciprocating compressor employing the reciprocating motor.
    Type: Grant

  • Discharge valve and valve assembly of reciprocating compressor having the same
    Patent number: 7766036
    Abstract: A discharge valve (100) of a compressor is disclosed. The discharge valve (100) contains a spring-loaded valve body (120). Valve body (120) is preferably made of nonferrous metal like aluminum or magnesium and is coated by a covering (110) of uniform thickness, the covering (110) being preferably made of plastic material like polyetheretherketone (PEEK) by insertion molding. By that way a wear resistant and light-weight discharge valve is produced.
