- A compressor assembly including a housing, a motor and a compression mechanism disposed within the housing, the compression mechanism driven by the motor. A pulsating discharge fluid flow emanates from the compression mechanism through a first conduit; the first conduit having an outlet which is open to a discharge muffler chamber. A standing pressure waveform is established by the first pulsating discharge fluid flow within the discharge muffler chamber. A second conduit is provided which has an inlet which is open to the discharge muffler chamber and disposed outside the standing pressure waveform therein, and an outlet through which discharge fluid exits, whereby the magnitude of the discharge pulse transmitted by the discharge fluid is attenuated. The present invention also provides a compressor assembly including a compression mechanism and a discharge muffler chamber having a substantially hemispherical inner surface and a central axis. First and second conduits are in fluid communication through the discharge muffler chamber, the openings of the first and second conduits within said discharge muffler chamber are directed substantially towards the central axis and oriented at approximately a right angle relative to each other therealong. A discharge fluid flow is received in the discharge muffler chamber from the compression mechanism via the first conduit. The discharge fluid flow contains pressure pulses of a fast magnitude. The discharge fluid flow is exhausted from the discharge muffler chamber via the second conduit, the discharge fluid flow exhausted from the discharge muffler containing pressure pulses of a second magnitude less than the first magnitude.
