摘要： A compressor has a swash plate located in a crank chamber and tiltably mounted on a drive shaft. A piston is operably coupled to the swash plate and is located in a cylinder bore. The inclination of the swash plate is varied according to the difference between the pressure in the crank chamber and the pressure in the cylinder bore. The compressor has a supply passage for connecting a discharge chamber with the crank chamber. A control valve is located in the supply passage for adjusting the amount of the gas introduced into the crank chamber from the discharge chamber through the supply passage. The control valve includes a valve body and a solenoid selectively excited and de-excited based on a supply of electric current from a driver to actuate the valve body. The solenoid generates a counter-electromotive force based on the self-inductance of the solenoid when the solenoid is de-excited. A protector, such as a diode, is connected in parallel with the solenoid. The protector passes the current based on the counter-electromotive force therethrough to prevent the current based on the counter-electromotive force from being supplied to the driver.

摘要： An automobile moves at a traveling speed in accordance with the position of an acceleration pedal. A compressor is driven by the engine of the automobile. The discharge displacement of the compressor is adjusted by an external control procedure. When the position of the acceleration pedal reaches a determining value, or above at which it is determined that engine power is needed for accelerating the vehicle, the compressor is controlled such that the discharge displacement decreases. The determining value is selected by a controller in relation to the traveling speed detected by a speed sensor. The determining value increases as the speed increases.

摘要： A swash plate is arranged to tilt between a maximum inclining angle and a minimum inclining angle based on differential pressure between a crank chamber and a suction chamber. At least one single-headed piston, that is coupled to the swash plate, is disposed in an associated cylinder bore and reciprocates at a stroke according to the inclining angle of the swash plate to compress refrigerant gas introduced to the cylinder bore from an external refrigerant circuit via the suction chamber. A pressure supply passage connects a discharge chamber with the crank chamber to supply the refrigerant gas from the discharge chamber into the crank chamber so as to increase the pressure in the crank chamber and a flow passage which allows flow of the refrigerant gas from the crank chamber to the suction chamber. An introducing passage introduces the refrigerant gas with low temperature from the external refrigerant circuit to substantially equalize the pressures in the crank chamber and the suction chamber. Movable elements selectively open and close the introducing passage in association with the maximum inclining angle and minimum inclining angle of the swash plate.

摘要： A compressor has an internal refrigerant gas passage selectively connected to and disconnected with an external refrigerant circuit separately provided from the compressor. The compressor has a reciprocable piston in a cylinder bore formed 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 and inclining motion with respect to the drive shaft. The swash plate is movable between a maximum incline and a minimum incline. A disconnecting apparatus disconnects the internal refrigerant gas passage from the external refrigerant circuit when the swash plate is at its minimum incline. A restricting member restricts the amount of gas to be passed through the internal refrigerant gas passage in association with the disconnecting apparatus when the swash plate moves.

摘要： A compressor has a swash plate tiltable between a maximum and minimum inclining angles with respect to an axis of the drive shaft according to a difference between pressures in a crank chamber and a suction chamber. An electromagnetic valve is disposed in a pressure passage, and opens or closes the pressure passage according to instruction of an external computer. This instruction is based on an operation status of the compressor so that the electromagnetic valve adjusts the pressure in the crank chamber. The pressure passage connects the crank chamber and the suction chamber. The swash plate is inclined toward the maximum inclining angle when the pressure passage is open to release the pressure in the crank chamber to the suction chamber. The swash plate is inclined toward the minimum inclining angle when the pressure passage is closed to increase the pressure in the crank chamber. A disconnecting element is disposed between the external circuit and the suction chamber to disconnect the external circuit with the suction chamber in association with the swash plate driven to the minimum inclining angle.

摘要： In a housing 1, 2, a rotor 11 is secured to a drive shaft 6 and a sleeve 12 is supported movably. A rotary swash plate 14 is tiltably supported on the sleeve 12 and is coupled to the rotor 11. Coupled to the rotary swash plate 14 are pistons 8 which move in the respective bores 9. A fluid is supplied to each bore 9 from a suction chamber 20, and a fluid compressed by each piston 8 is discharged to a discharge chamber 21. A control valve 25 controls the difference between the pressure in the suction chamber 20 and the pressure in a crank chamber 5 to change the inclination angle of the rotary swash plate 14, so that the discharge displacement of a compressor becomes variable. In the housing 1, a spool 32 is movably provided while enclosing the drive shaft 6. With the spool 32 entered in the crank chamber 5, when the sleeve 12 engages with the spool 32, the movement of the rotary swash plate 14 is restricted to the position that sets the discharge displacement of the discharge chamber 21 to a predetermined restricted displacement. By supplying the pressure in the discharge chamber 21 via a pressure supply passage 35 to retract the spool 32 from the crank chamber 5, the rotary swash plate 14 is permitted to move to the position where the discharge displacement to the discharge chamber 21 becomes zero.

The compressor has a plurality of pistons reciprocable in a plurality of cylinder bores in a housing for compressing gas. The compressor comprises a drive shaft 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. A rotary valve is disposed in the middle of the internal refrigerant gas passage for synchronously rotating with the drive shaft. The rotary valve has a refrigerant supply passage for sequentially supplying the refrigerant gas in the internal refrigerant gas passage to each cylinder bore. A disconnecting device disconnects the external refrigerant circuit from the internal refrigerant gas passage when the swash plate is at the minimum inclined angle.

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.
