摘要： A variable displacement compressor includes a rotor, which is fixed to a drive shaft, and a pivotal swash plate, which is supported on the drive shaft and slides in an axial direction along the drive shaft. A hinge mechanism is located between the rotor and the swash plate. The hinge mechanism rotates the swash plate integrally with the rotor and guides the pivoting and the sliding motion of the swash plate. The hinge mechanism includes a swing arm, which extends from the swash plate. The swash plate is made of aluminum or aluminum alloy material. The swing arm is separate from the swash plate and is made of iron-based metal material. Therefore, while the swash plate is light, the hinge mechanism is strong.

摘要： A capacity control valve for a variable capacity refrigerant compressor for controlling the compressor capacity by adjustably changing a pressure level prevailing in a crank chamber of the compressor, the capacity control valve having a valve mechanism opening and closing a portion of a gas-supply passageway extending between a discharge chamber and the crank chamber of the compressor, and a discharge pressure responsive unit controlling a movement of the valve mechanism in such a manner that only when the discharge pressure of the refrigerant gas is below a predetermined pressure level, does the valve mechanism reduce the opening area of the portion of the gas-supply passageway due to a force provided by the discharge pressure responsive unit in addition to a different force produced by the discharge pressure of the refrigerant gas. The capacity control valve enables the compressor to produce a satisfactory refrigerating performance irrespective of the environmental temperature.

摘要： A swash plate is mounted on a drive shaft disposed in a housing having a gas suction chamber in such a way that the swash plate is rotatable integrally with the drive shaft. A plurality of cylinder bores are formed around the drive shaft, extending along the drive shaft. Disposed in each cylinder bore is a piston, which reciprocates between top and bottom dead centers by undulating movement of the swash plate caused by rotation of the drive shaft. A compression chamber where gas is compressed by the reciprocal movement of the piston is defined in each cylinder bore. Provided between the drive shaft and the swash plate is a mechanism for altering an angle of the swash plate with respect to the axis of the drive shaft to change a reciprocal stroke of the piston to thereby control compression displacement. A rotary valve is provided at the drive shaft to be rotatable integrally with the drive shaft. The rotary valve has a passage for permitting uncompressed gas to move to each compression chamber from the suction chamber in synchronism with the reciprocal movement of the piston during rotation of the rotary valve before the piston reaches the bottom dead center. The compressor further comprises a mechanism for forcibly changing the timing at which the piston substantially reaches the top dead center in accordance with an inclined angle of the swash plate.

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 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.
