Abstract
A compressor that reduces pressure pulsation includes a mounting member for attaching the compressor to a vehicle support. The mounting member is integrally formed with an end wall of a rear housing member. A suction chamber and a discharge chamber are defined in the rear housing member. The discharge chamber is located outside the suction chamber and surrounds the suction chamber. An auxiliary chamber is formed in the mounting member. The auxiliary chamber is centrally located. The auxiliary chamber increases the volume of the suction chamber, which reduces pulsation. Since the auxiliary chamber is formed in the mounting member, neither the weight or the volume of parts that might interfere with other devices is increased.
