ABSTRACT:
A reciprocating compressor includes a case to which a suction pipe and a discharge pipe are respectively connected, having a closed space; a reciprocating motor disposed inside the case, for generating a reciprocating force; a compressing unit receiving the reciprocating force generated from the reciprocating motor, for compressing a fluid; and a separation plate for dividing the closed space of the case into a low pressure portion into which a fluid is sucked through the suction pipe and a high pressure portion from which a fluid compressed in the compressing unit is discharged. Accordingly, the reciprocating compressor cuts off vibration generated from the compressing unit and the reciprocating motor and thus reduce the vibration transmitted to the compressor case and other elements so that noise can be reduced, life spans of other elements can be lengthened, and reliability of the compressor can be improved.
