Abstract
A multi-cylinder piston type compressor having an axially extending cylinder block with cylinder bores formed therein and closed on at least one axial end by a housing defining therein suction and discharge chambers and provided therein with a reciprocative piston mechanism for drawing, compressing, and discharging a refrigerant gas. The compressor also has a valve plate member arranged between the cylinder block and the housing for defining therein suction ports and discharge ports, a suction valve sheet member defining therein suction valves openably closing the suction ports and discharge apertures for introducing the refrigerant gas after compression from the cylinder bores into the discharge chamber of the housing via the discharge port of the valve plate member. The compressor also has an internal pulsation and noise suppression unit provided by extensions formed in the suction valve sheet member and adjacent to the discharge ports of the valve plate member.
