A compressor 
assembly may include a shell, a 
discharge fitting, a 
muffler, a compression mechanism, and a motor. The shell may have an opening therethrough with the 
discharge fitting generally extending therefrom. The 
muffler may be in communication with the 
discharge fitting and may be external to the shell. The 
muffler may have an inlet 
proximate the discharge fitting, an outlet distal from the discharge fitting, and a body portion extending therebetween. The muffler may include a valve 
assembly proximate the outlet. The compression mechanism may be contained within the shell and include a suction inlet and a discharge passageway. The discharge passageway may be connected to the opening in the shell for direct discharge of 
refrigerant from the compression mechanism to the discharge fitting. The motor may be contained within the shell and drivingly coupled to the compression mechanism.
