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.
