Abstract: A reciprocating compressor includes a cylinder that defines a compressing space and a discharge muffler configured to receive refrigerant compressed in the cylinder and to discharge the refrigerant. The discharge muffler includes a discharge muffler body and a discharge guide supported by the discharge muffler body. The discharge muffler body defines a discharge space configured to receive the refrigerant from the cylinder and includes a wall protruding from an inner circumferential surface of the discharge muffler body. The discharge guide is coupled to the wall and includes a pipe that defines a pipe inflow hole configured to receive the refrigerant from the discharge space and a pipe outflow hole configured to discharge the refrigerant. The discharge guide further includes a fixing bracket that couples the pipe to the discharge muffler body.

Abstract: A compressor includes a shell that defines an enclosed space inside the shell, an electric motor unit located in the enclosed space of the shell and configured to generate a driving force, and a compression unit located in the enclosed space of the shell and configured to compress refrigerant. The compression unit includes a cylinder and a piston that is configured to reciprocate in the cylinder based on the driving force transmitted from the electric motor unit. The shell includes a plurality of heat radiation fins that are located at an outer circumferential surface of the shell and that are configured to emit heat generated inside the shell to an outside of the shell.

Abstract: A reciprocating compressor and a method for manufacturing a reciprocating compressor are provided. The reciprocating compressor may include a damper provided at a cylinder block. The damper may include a damper base coupled to the cylinder block and formed of plastic, and a rubber damping portion provided on the damper base to prevent contact between the damper base and the shell, so that friction noise between a base and the shell of the compressor may be reduced.
