ABSTRACT:
A rear housing for a compressor reduces NVH without increasing the overall size of the compressor or inducing flow loss. Generally, the compressor includes a cylinder block receiving lower pressure fluid from the rear housing and providing higher pressure fluid back to the rear housing. The rear housing includes an annular outer wall and an annular inner wall defining a suction chamber and a discharge chamber. An inlet is in fluid communication with the suction chamber. An outlet is in fluid communication with the discharge chamber. The outlet includes a discharge passageway having a tubular member projecting into the discharge chamber. The tubular member is defined by a side wall and a closed end wall. The side wall includes a plurality of holes fluidically connecting the discharge chamber and the discharge passageway.
