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.

摘要： A compressor includes a rotary drive shaft having a first end and a second end, both the ends being rotatably supported by opposing walls of a crank chamber defined in a casing and a swash plate tiltably mounted on the drive shaft and operably coupled with a piston in a cylinder bore. A rotation of the drive shaft results in a reciprocating movement of the piston for compressing refrigerant gas in a cylinder bore. A rotary member is secured to the first end which extends outside the casing. the rotary member supplies a power to the drive shaft from a power supply. A support member, disposed between the rotary member and the first end, protrudes outward from the casing. A first bearing, disposed between the support member and the rotary member, receives a thrust load and a radial load acting on the rotary member when the rotary member rotates. A second bearing, disposed between the casing and the second end, receives the radial load acting on the rotary member when the rotary member rotates.

摘要： In a housing, a rotor is secured to a drive shaft, and a sleeve is supported movably on the drive shaft. A rotary swash plate is tiltably supported on the sleeve and is coupled to the rotor. Coupled to the rotary swash plate are pistons which move in the respective bores. A refrigerant is supplied to each bore from a suction chamber, and the refrigerant compressed by each piston is discharged from the bores to a discharge chamber. A control valve controls the difference between the pressure in the suction chamber and the pressure in a crank chamber to change the inclination angle of the rotary swash plate, so that the discharge displacement of a compressor becomes variable. In the housing, a spool is slidably provided while enclosing the drive shaft. With the spool advancing into the crank chamber, (when the sleeve engages with the spool,) shifting of the rotary swash plate is restricted to the position that sets the discharge displacement of the discharge chamber to a predetermined restricted displacement. A gear pump which is driven interlocking with the drive shaft is provided in the housing. The discharge pressure of the gear pump is selectively supplied to the spool depending on the level of the discharge pressure of an evaporator. By retracting the spool from the crank chamber based on this pressure supply, the rotary swash plate is permitted to move to the position where the discharge displacement to the discharge chamber becomes zero.

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.

摘要： A variable capacity type swash plate compressor includes a novel hinge means. The hinge means includes a supporter arm, a main guide pin, and an auxiliary guide pin. The supporter arm is disposed on the rotor projectably therefrom toward the swinging swash plate, and has a main guide hole extending perpendicularly with the driving shaft. The main guide pin is inserted rotatably into the main guide hole. The auxiliary guide pin is inserted slidably into a hole, formed in one of the main guide pin and the swinging swash plate, perpendicularly with the main guide pin at one end, and it is fixed to another one of the main guide pin and the swinging swash plate at the other end. With the hinge means, the top clearances of the pistons can be always maintained virtually uniformly, and the moments resulting from the compression reactive forces can be inhibited from interfering with the discharge capacity control. Additionally, the compressor can attain the reduction in the manufacturing costs.

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.

摘要： A compressor has a refrigerant gas circulation passage selectively connected to and disconnected from an external refrigerant circuit. The compressor has a swash plate supported on a drive shaft for integral rotation with inclining motion with respect to the drive shaft which swash plate is coupled in driving relationship to a plurality of pistons which move reciprocatably within cylinder bores for compressing the gas. 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.
