ABSTRACT:
An axial multi-piston compressor includes a drive shaft, a cylinder block having cylinder bores formed therein and surrounding the drive shaft, and a plurality of pistons slidably received in the respective cylinder bores, wherein the pistons are successively reciprocated in the cylinder bores by a rotation of the drive shaft so that a suction stroke and a discharge stroke are alternately executed in each of the cylinder bores. During the suction stroke, a fluid is introduced into the cylinder bore concerned, and during the compression stroke, the introduced fluid is compressed and discharged from the cylinder bore concerned, such that a residual part of the compressed fluid is inevitably left in the cylinder bore concerned when the compression stroke is finished. The compressor further includes a rotary valve for allowing the residual part of the compressed fluid to escape from the cylinder bore concerned into two other cylinder bores disposed adjacent to each other and subjected to the compression stroke.
