ABSTRACT:
In an improved swash plate type compressor in which a first end block, holding a first valve plate against one end of the cylinder block, defines a first input plenum and an output plenum with input and output valve means for a first set of cylinder chambers, a partition plate is secured between the other end of the cylinder block and a second end block and holds a second valve plate against that end of the cylinder block, defining for a second set of cylinder chambers a second input plenum with input valve means and an output chamber with an output valve means. The second end block defines inlet and outlet buffering chambers to which an inlet and an outlet open. The cylinder block is formed with an input transfer passage communicated at its ends to the first and second input plenums. The partition plate is formed with an output transfer aperture for the output chamber, communicating it to the outlet buffering chamber. Also, a means communicates from the inlet buffering chamber to the input transfer passage. Thereby, input and output pulsations are well attenuated.
