摘要： A variable displacement compressor comprises a housing containing a cylinder block, a plurality of pistons disposed in the cylinder block, a crank chamber, a rotatable drive shaft, a drive plate mounted on the drive shaft such that it may rotate integrally with the drive shaft, a rotary journal which can be pivoted with respect to the drive plate and a swash plate, supported on the rotary journal, for causing the pistons to compress a fluid. The inclination angle of the swash plate is controlled in relation to the internal pressure in each cylinder, and to the pressure in the crank chamber. The compressor further has a pin mechanism, pivotally mounted on the drive plate, for coupling the drive plate and the rotary journal. The pin mechanism is adapted to slide with respect to the rotary journal and to pivot with respect to the drive plate, when the rotary journal pivots with respect to the drive plate.

摘要： A method for machining a variable displacement compressor piston. The piston is connected to a swash plate by a pair of semi-spherical shoes. One end of the piston has a slot for receiving the swash plate. The slot includes a pair of opposed walls. Each wall has a concave spherical recess for supporting one of the shoes. When forming the recesses, a tool having an asymmetrical spherical cutter is placed between the slot walls in the piston. Then, the piston is rotated about a machining axis that is perpendicular to the axis of the piston and intersects the midpoint between the walls. Then, the tool is moved such that the center of the cutter is located on the rotation axis of the piston. This forms the recesses on the walls such that the recesses conform to a single sphere, the center of which is located on the axis of the piston.

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.

A control valve is arranged to change the pressure in the crank chamber, to vary the capacity of the compressor by changing the inclination angle of the swash plate by changing the pressure in the crank chamber. The control valve has independently movable first and second plungers and a coil arranged around the first and second plungers so that the coil generates an electromagnetic attraction force acting on and between the first and second plungers. First and second valve elements provided on the first and second plungers can adjust the degree of opening of the first and second fluid passages.

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.
