ABSTRACT:
A multi-cylinder swash-plate-type compressor having a combined cylinder block closed on both axial ends by front and rear housings and provided therein with a reciprocative piston mechanism for sucking, compressing, and discharging a fluid, such as a refrigerant gas. The combined cylinder block is provided with a mounting bracket on the outer circumference thereof and suction and discharge ports formed in the outer circumference at positions adjacent to the mounting bracket. The compressor further has damping chambers arranged adjacent to the suction and discharge ports for suppressing pulsation in suction and discharge pressures of the refrigerant gas during the operation of the compressor. The damping chambers have considerable volumes and cross-sectional area.
