Document Type and Number:
Japanese Patent JP2682290
Kind Code:
B2
Abstract:
An axial multi-piston compressor comprises 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 cylinder bores, respectively, 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, and during the compression stroke, the introduced fluid is compressed and discharged from the cylinder bore such that a residual part of the compressed fluid is inevitably left in the cylinder bore when the compression stroke is finished. The compressor further comprises a rotary valve for allowing the residual part of the compressed fluid to escape from the cylinder bore into another cylinder bore not governed by the compression stroke, whereby a pressure of the residual part of the compressed fluid can be lowered.
