摘要： A swash plate type variable displacement compressor is disclosed for adjusting an inclined angle of a swash plate (13) placed in a crank chamber (2a) in accordance with a pressure difference between the crank chamber (2a) and a gas suction chamber (4a) and for compressing gas supplied to compression chambers (18) from the gas suction chamber (4a) by pistons (21) that reciprocate with a stroke according to the inclined angle of the swash plate (13) in order to thereby control a volume of gas to be discharged from a gas discharge chamber (4b). A communication passage (23) connects the gas discharge chamber (4b) to the gas suction chamber (4a), and a branch passage (24) branching from the communication passage (23) is connected to the crank chamber (2a). Disposed in the communication passage (23) is a valve (25, 45) which normally blocks the communication passage (23) and opens the communication passage (23) to alter pressure in the crank chamber (2a).

摘要： In a swash-plate compressor, pistons are slidably received in cylinder bores. A drive shaft is extended through a crank chamber, and is rotated through an electromagnetic clutch means associated therewith. A conversion mechanism is provided on the shaft for converting a rotational movement of the shaft into a reciprocation of each piston in the corresponding cylinder bore such that a suction stroke and a discharge stroke are alternately executed therein. A fluid is introduced from a suction chamber into the bore during the suction stroke, and during the compression stroke, the fluid is compressed in and discharged from the bore into a discharge chamber. The conversion mechanism is constituted such that a stroke length is shortened in response to an increase of a pressure in the crank chamber, and vice versa. A first passage communicates the crank with the suction chamber, and a second passage communicates the crank chamber with the discharge chamber. A control valve is provided in one of the first or second passage, and is magnetically actuated by the clutch for controlling the pressure in the crank chamber such that the piston stroke can be minimized whenever the clutch is electrically deenergized.

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, 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 includes a rotary valve for allowing the residual part of the compressed fluid to escape from the cylinder bore into another cylinder bore governed by the compression stroke.

摘要： A plurality of pistons of a variable displacement compressor are reciprocatably disposed in cylinder bores which are formed in a housing. A drive shaft is rotatably supported in the housing. A lug plate is rotatable with the drive shaft. A swash plate is tiltably and slidably mounted on the drive shaft. The swash plate is operatively coupled with the pistons. A hinge mechanism connects the lug plate and the swash plate. The hinge mechanism causes the pistons to reciprocate via the lug plate and the swash plate, in response to the rotational motion of the drive shaft. The hinge mechanism includes a pin, which has a first and a second end portions. The first end portion of the pin is slidably inserted into the swash plate. A support arm protrudes from the lug plate, and further includes a bush. The bush rotatably supports the second end portion of the pin.

摘要： An oil diverting unit, incorporated in a compressor housing of a refrigerant compressor for a climate control system of an automobile, cooperating with a shaft seal unit mounted on a drive shaft of the compressor, so as to divert a flow of the lubricating oil which was suspended in the refrigerant gas and has leaked out of the interior of the compressor housing, to thereby prevent the lubricating oil from reaching a solenoid clutch mounted on a front portion of the drive shaft of the compressor. The oil diverting unit has an oil blocking plate member made of elastic material so that the plate member is elastically press-fitted in the compressor housing so as to define an oil dam for holding the lubricating oil and permitting the oil to be drained from the dam through a drain passageway toward the exterior of the compressor housing.
