摘要： A compressor has a housing body, a drive shaft, a swash plate, and a piston. The swash plate converts rotation of the drive shaft to reciprocating movement of the piston in a cylinder bore. The piston compresses gas supplied to the cylinder bore from an external circuit via a suction chamber and discharges the compressed gas to a discharge chamber. The swash plate is tiltable with respect to a plane perpendicular to the longitudinal axis of the drive shaft according to differential pressure between the crank chamber and the suction chamber. The swash plate controls the displacement of the compressor based on the inclination thereof. A spool is movable longitudinally between a first position and a second position in response to the inclination of the swash plate. The spool connects the external circuit with the suction chamber in the first position and disconnects the external circuit from the suction chamber in the second position. The housing body has a surface slidably engaged by the spool. A coating layer is provided on at least one of the spool and the slide surface to reduce frictional resistance occurring due to the sliding movement of the spool on the slide surface. A second coating layer is provided on an end surface of the spool to lubricate and thereby reduce frictional resistance with the housing surface along the periphery of the suction passage leading into the shutter chamber occurring due to rotation of the spool, and also to improve the seal between the end surface of the spool and the housing when in the second position closing off the suction passage.

摘要： An electromagnetic valve (32) opens and closes a pressurizing passage (31). When the pressurizing passage (31) is opened, a swash plate (15) mounted on a rotary shaft (9) inclines toward the minimum inclination. As the swash plate (15) inclines toward the minimum inclination, the swash plate (15) counteracts the spring force of a suction passage opening spring (24) and pushes a transmitting cylinder (28) and a shutter (21). The shutter (21) abuts against a positioning surface (27) when the swash plate inclination corresponds to a minimum inclination and disconnects a suction passage (26) from a suction chamber (3a). The disconnection impedes refrigerant circulation in the external refrigerant circuit (35). A refrigerant circulation controlling circuit (42) energizes the electromagnetic valve (32) and opens the pressurizing passage (31) for a certain time period starting from when a drive electric source (14) is activated.

摘要： A swash plate type compressor is connected with an external refrigerant gas circuit. A device accommodated in the compressor disconnects the external circuit with the suction chamber when the swash plate is at the minimum inclining angle. A pressure decreasing passage creates the connection between the crank chamber and the suction chamber to decrease the pressure in the crank chamber. This passage releases the pressure in the crank chamber to the suction chamber when the pressure in the crank chamber is greater than the pressure in the suction chamber so that the swash plate is inclined toward the maximum inclining angle. An adjusting device adjusts the pressure in the pressure decreasing passage so that the pressure decreasing passage is opened to a greater degree when the swash plate is at the maximum inclining angle than when the swash plate is between the maximum and minimum inclining angles.

The swash plate is movable between a maximum inclined angle and a minimum inclined angle. A disconnecting valve disconnects the discharge chamber in the circulation passage from the external refrigerant circuit when the swash plate is at the minimum inclined angle. A bleed hole bleeds the refrigerant gas from the refrigerant circulation passage to the external refrigerant circuit to suppress rapid increase of the inclined angle when the disconnecting valve operates.

摘要： A variable displacement compressor which has a suction chamber, a discharge chamber, and a crank chamber. The displacement of the compressor is controlled by supplying refrigerant to the crank chamber from the discharge chamber via a pressurizing passage and releasing the gas into the suction chamber via a pressure releasing passage. An increase in the pressure in the crank chamber decreases the displacement, and a decrease in the pressure in the crank chamber increases the displacement. A displacement controlling structure of the compressor includes an electromagnetic valve which alters the size of an area of the pressurizing passage. A computer controls the electromagnetic valve in accordance with commands to alter the displacement. The computer enlarges the opened area of the pressurizing passage by controlling the electromagnetic valve in response to commands to reduce the displacement.

摘要： A compressor having an internal refrigerant gas passage selectively connected to and disconnected from an external refrigerant circuit separately provided from the compressor is described. The compressor has a plurality of pistons reciprocable in a plurality of cylinder bores in a housing for compressing gas supplied from the external refrigerant circuit to the internal refrigerant gas passage. A drive shaft is rotatably supported by the housing. A swash plate is supported on the drive shaft for integral rotation with inclining motion with respect to the drive shaft. The swash plate is movable between a maximum inclined angle and a minimum inclined angle. The disconnecting device disconnects the internal refrigerant gas passage from the external refrigerant circuit when the swash plate is at the minimum inclined angle. The internal refrigerant gas passage includes a first passage which connects a crank chamber and a suction chamber to deliver the refrigerant gas from the crank chamber to the suction chamber. A control valve detects the pressure in the first passage to control the inclined angle of the swash plate.

摘要： A housing has a crank chamber and a plurality of cylinder bores. The housing also has a discharge chamber and a suction chamber, which are communicatable with the cylinder bores. A drive shaft is supported in the housing, and pistons are accommodated in the respective cylinder bores. A swash plate is supported on the drive shaft in such a manner that its inclined angle can be altered, so that the undulation of the swash plate causes the pistons to reciprocate. When this compressor is running with the swash plate set upright, a controller activates an electromagnetic solenoid to supply a lubricating oil to a pressure chamber from an oil-supplying pump. This causes the spool to shift to temporarily hold the swash plate to an inclined position from the upright position.
