    摘要: Pistons are accommodated in each cylinder bores of a variable displacement compressor. A swash plate is coupled to the piston for converting rotation of the drive shaft to reciprocation of the pistons. A thrust bearing located between a rotor and a housing of the compressor. The outermost load-bearing points of the thrust bearing are radially farther from the axis of the drive shaft than the axes of the pistons. This permits the thrust bearing to directly receive a reaction forces from the pistons through the rotor without applying a moment to the bearing.

    摘要: A variable displacement compressor includes a swash plate supported tiltably on a drive shaft and slidable in axial directions of the drive shaft. The swash plate has a central support hole into which the drive shaft is inserted. The swash plate has a top dead center point for positioning the piston at a top dead center position and a bottom dead center point for positioning the piston at a bottom dead center position. The center of gravity of the swash plate is displaced from the axis of the drive shaft toward the top dead center point. This location of the center of gravity maintains the radial position of the swash plate relative to the drive shaft by centrifugal force acting on the swash plate when the swash plate rotates. As a result, the compressor is quieter and more stable.

    摘要: A heat-insulating mechanism in a compressor which introduces refrigerant gas from a suction pressure region to a compression chamber and discharges the refrigerant gas from the compression chamber to a discharge pressure region has a circular passage, a communication passage, a cylindrical member and a passage heat-insulating member. The circular passage, which is a portion of the suction pressure region, has a circular cross-section, and is in communication with an external refrigerant circuit. The communication passage, which is a portion of the suction pressure region, intersects the circular passage for connection therewith, and is communicable with the compression chamber. The cylindrical member is fitted into the circular passage. The passage heat-insulating member made of an insulating material covers at least a portion of a passage wall surface which forms the communication passage. Rotation of the cylindrical member is prevented by engaging the passage heat-insulating member with the cylindrical member.

The drive plate is tiltable between a maximum inclination position and a minimum inclination position according to a difference between the pressure in the crank chamber and the pressure in the cylinder bore. The cylinder block has a shutter chamber opening to the first end and the second end. A shutter member is accommodated in the shutter chamber. The shutter member is movable between a first position and a second position in response to the inclination of the drive plate to selectively connect and disconnect an external circuit with an suction chamber. The drive plate is held at the minimum inclination position when the shutter member is positioned in the second position. The shutter chamber has a diameter that is constant in an axial direction with respect to the shutter chamber. The shutter member is removably inserted into the shutter chamber from the second end of the cylinder block.

    摘要: An improved lubricating structure of a compressor is disclosed. A swash plate is tiltably supported on the drive shaft for an integral rotation therewith. A plurality of pistons are operably coupled to the swash plate. The rotation of the swash plate is converted to a reciprocal movement of each piston in an associated cylinder bore to compress and discharge gas that contains oil. A clearance is defined by the cylinder bore and the piston enabling the compressed gas to flow out from the cylinder bore to the swash plate. The swash plate has an operation area that receives greatest compression load based on reaction force of the compressed gas acting on the piston when the swash plate rotates. The swash plate has at least one bore for attaching the swash plate to a jig when the swash plate is ground during its manufacturing process. The bore is arranged to allow the gas flow out to the swash plate from the cylinder bore through the clearance to flow to the operation area.

    摘要: In a swash plate type compressor, refrigerant in a discharge pressure region is introduced into a crank chamber through a supply passage while the refrigerant in the crank chamber is drawn out to a suction pressure region through a bleed passage for controlling pressure in the crank chamber, whereby inclination angle of a swash plate is changed. A heat-generating sliding portion is provided in the crank chamber. The supply passage includes a communication port that communicates with the crank chamber and a first throttle portion for throttling the refrigerant. At least parts of the supply passage and the bleed passage are formed in a drive shaft. A part of the bleed passage formed in the drive shaft is located between a part of the supply passage formed in the drive shaft and an outer peripheral surface of the drive shaft.
