摘要： 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, 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 includes a rotary valve for allowing the residual part of the compressed fluid to escape from the cylinder bore into another cylinder bore governed by the compression stroke.

摘要： A plurality of pistons are provided in the associated cylinder bores arranged around the rotary shaft. Each piston reciprocates in relation to the rotation of the rotary shaft to execute suction, compression and discharge of the refrigerant gas. A valve chamber is disposed in the vicinity of the cylinder bore. A plurality of ports are arranged to communicate the valve chamber to the associated cylinder bores. The valve chamber has a rotary valve which rotates in relation to the reciprocating motion of the pistons. A suction passage is formed in the rotary valve to be sequentially communicated with each port in synchronism with the rotation of the rotary valve in order to introduce the refrigerant gas into each cylinder bore. A seal zone is included in the rotary valve, which sequentially blocks each port in synchronism with the rotation of the rotary valve. A groove is defined in the rotary valve, which is capable of guiding the refrigerant gas entering between the valve chamber and the rotary valve.

摘要： A variable displacement swash plate type compressor comprises a suction chamber, a discharge chamber and a crank chamber. A flow rate control valve mechanism is provided along a refrigerant supply passage, which connects the discharge chamber to the crank chamber. The flow rate control valve mechanism is provided with a discharge pressure chamber and an intermediate chamber. A valve hole is provided between the discharge pressure chamber and the intermediate chamber, to permit both chambers to communicate with each other. A pressure sensitive member is provided in the intermediate chamber to separate the intermediate chamber into a first and a second pressure sensitive chambers. The first pressure sensitive chamber communicates with the discharge pressure chamber via the valve hole. The second pressure sensitive chamber communicates with either the crank chamber or the suction chamber. The pressure sensitive member is displaceable as a function of the pressure difference between the first and second pressure sensitive chambers. A restriction permits the first pressure sensitive chamber and the crank chamber to communicate with each other. A valve body is coupled to the pressure sensitive member to be displaceable in synchrony with the action of the pressure sensitive member, and regulates the opening of the valve hole according to the displacement. A return member biases the valve body and the pressure sensitive member to a valve open position when the pressure in the discharge chamber becomes almost zero.
