Abstract: A compressor includes a case, a compression unit having a cylinder, a piston disposed inside the cylinder, and a driving unit for reciprocating the piston, and a support unit elastically supporting the compression unit to be spaced apart from an inner surface of the case. The support unit includes a wire spring having a plurality of linear portions arranged in parallel with one another and curved portions each connecting two adjacent linear portions. The wire spring includes a first wire spring and a second wire spring symmetrically disposed with each other. The wire spring includes a connecting portion connecting the first wire spring and the second wire spring, and the connecting portion is supported by the case. Accordingly, a simplified structure can be obtained and a manufacturing cost can be reduced.

Abstract: The present disclosure relates to a compressor including a case, a compression unit provided inside the case, and a driving unit, wherein the compression unit includes a cylinder having a compression space, a piston reciprocating inside the cylinder, a discharge cover covering the compression space, a first plenum disposed inside the discharge cover and having a discharge space and a coupling space, a second plenum disposed inside the discharge cover and defining a movement channel through which refrigerant moves, a rib disposed in the movement channel, and a communicating portion through which the discharge space and the movement channel communicate with each other, wherein the refrigerant discharged from the compression space moves along the discharge space, the communicating portion, and the movement channel, whereby pulsation caused by the discharge of the refrigerant can be reduced.
