    摘要: A variable displacement compressor is disclosed that draws refrigerant from a suction pressure zone and discharges the refrigerant to a discharge pressure zone, and controls displacement according to a pressure in a control pressure chamber. The compressor has a cam body, pistons, a supply passage, a release passage, and an on-off valve. The inclination angle of the cam body is changeable based on the pressure in the control pressure chamber. A piston reciprocates in each cylinder bore as the cam body rotates. The supply passage supplies the refrigerant in the discharge pressure zone to the control pressure chamber. The release passage releases the refrigerant in the control pressure chamber to the suction pressure zone. The on-off valve selectively opens and closes the release passage in response to changes of the temperature. The on-off valve shuts off the release passage when the temperature is equal to or higher than a predetermined temperature.

    摘要: A rotor is fixed to a drive shaft supported by a housing. A swash plate is supported slidably and tiltably by the drive shaft. A hinge mechanism is provided between the rotor and swash plate. The hinge mechanism comprises two rotor-side protrusions provided in the rotor and a protruding portion provided in the swash plate. The protruding portion is inserted between side faces in which the two rotor-side protrusions face each other, and perform power transfer between the rotor and swash plate by two-dimensionally abutting against a side face of one of the rotor-side protrusions. A concavity is provided in the side face of the rotor-side protrusion. Therefore, an area of the side face of the rotor-side protrusion abutting on the side face of the swash-plate-side protrusion decreases, and smooth change of discharge volume is achieved while controlling processing cost.

    摘要: A variable displacement compressor includes a swash plate guiding member that rotates integrally with and inclines relative to a drive shaft, a swash plate supported by the guiding member, and a piston engaged with the swash plate via a shoe. A clutch is located between the guiding member and the swash plate. The clutch is switched between an engaged state, where the clutch permits the guiding member and the swash plate to rotate integrally, and a disengaged state, where the clutch permits the guiding member and the swash plate to rotate relative to each other. Therefore, the compressor is capable of switching between a state where improving the displacement controllability is prioritized and a state where reduction of mechanical loss between the swash plate and the shoes is prioritized.

    摘要: A compressor includes pistons slidably accommodated in cylinder bores. A head and a skirt are formed at the ends of the piston. The head has a peripheral surface that always contacts the inner surface of the cylinder bore. The skirt is coupled with a swash plate. An annular space opens to the side of the piston. The annular space is located between the head and the skirt. A recess is located on the inner wall of a front housing and extends longitudinally in the axial direction of the piston. A projection is integrally formed on the skirt of the piston to engage with the recess. Rotation of the piston about its axis with respect to the cylinder bore is restricted by the engagement of the projection with the recess. A force acting on the piston in a direction transverse to the axis of the piston is received by the recess through the projection.

    摘要: A compressor having a cylinder bores and pistons are disclosed. Each piston moves in the associated cylinder to compress gas therein. Each piston slides on an inner peripheral wall of an associated cylinder to seal a compression chamber. Each piston includes an outer peripheral surface and cavities. The outer peripheral surface has a seal to seal the cylinder and a pressure receiving surface to receive reaction forces from the wall of the cylinder. A low friction layer is formed on the pressure receiving surface. The layer facilitates the sliding movement of the piston with respect to the cylinder.

    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.
