Abstract: A discharge muffler of a hermetic rotary compressor has a simple structure, and reduces the noises which occur due to pulsation of refrigerant and impact to a valve when the refrigerant, which is compressed in an inner space of a cylinder of the compressor, is discharged. The discharge muffler includes a muffler body which is disposed above an upper flange to define a noise reducing space with the upper flange, and has a pair of discharge openings through which the refrigerant, which is discharged to the noise reducing space, is discharged, and a phase varying means for preventing the noises which occur due to the pulsation of the refrigerant and the impact to the valve which is disposed at the discharge port, from being discharged together with the refrigerant. The phase varying means also functions to vary the phases of the noises and to counterbalance the noises. The phase varying means comprises a pair of covers which extend from the muffler body toward centers of the discharge openings to cover approximately half portions of the discharge openings from above and from below, respectively, in an alternating pattern. Accordingly, the noise, which is produced when the refrigerant is discharged, is blocked by a pair of covers which are disposed at the discharge openings, and the phases of the noises are varied, so that the noises are counterbalanced. As a result, the great noise reduction effect is guaranteed with a simple structure.
