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.
