摘要： A variable capacity swash plate type compressor having a hinge unit having a support arm protruding from a back side of a rotor, and a guide pin having one end thereof fixed onto a rotatable swash plate. The support arm has guide holes or guide surfaces which are parallel with a plane passing through a central axis "O" of a drive shaft and the top dead center position of the swash plate, the holes extending in a direction in which the holes approach the drive shaft from the outer edge of the rotor. Sections taken so as to be perpendicular to the center lines of the holes (guide surfaces) can be circular. A spherical element interacting with the guide holes is arranged at the end of the guide pin away from the rotatable swash plate. Thus, the spherical element of the guide pin interacts with the guide holes so that the suction force, compressive reaction force and torque are sustained on a line.

摘要： A variable capacity single headed piston swash plate type refrigerant compressor is provided with a double fulcrum hinge mechanism having a pair of hinges for providing a pivotal connection between a rotary support element of a drive shaft and a swash plate assembly, causing reciprocation of a plurality of single headed pistons in cylinder bores for compressing a refrigerant gas. The pair of hinges of the double fulcrum hinge mechanism cooperate to absorb reaction forces of the compression and suction of the refrigerant gas acting from the pistons on the swash plate assembly to thereby prevent application of a local load to a sleeve element on which the swash plate assembly is turnably mounted.

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 variable displacement compressor includes a hinge mechanism having a pair of support arms integrally formed with and protruding from the drive plate, and guide pins which connect the swash plate with the support arms. Each support arm is formed having a unshaped cutaway portion defining a channel for supporting ball portion of the hinge mechanism. The ball portion pivotably secured in the channel portion of the support arm, is attached to guide pin which in turn connects to a bracket protruding from the swash plate. The ball portion transmits pressure & rotational forces generated by the pistons and rotational force of the drive plate respectively. The forces cause the ball portion of the hinge mechanism to impinge upon pre selected surface area of the u-shaped support arm. By impinging on these preselected surface areas of the u-shaped support arm, the ball portion will not disengage from the channel portion of the support arm. Moreover the shape of the support arm increases the motility of the ball portion and associate guide pin secured within the support arm. The guide pin is slidably inserted into either the support arm or the swash plate, and is rotatably supported by means of the support arm.

摘要： 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.
