摘要： PROBLEM TO BE SOLVED: To prevent a degradation in vehicle driveability resulting from a change in compressor delivery capacity. SOLUTION: An on-off switch 40 interposed in a feeder path between a power source G such as a vehicle battery and a coil 51 of a displacement control valve 31 is switchable between an on-position to allow an input of current to the coil 51 from the power source G and an off-position to allow no current input. When an on-off operation of an air conditioner switch 38, and a start/end of acceleration-cut control change the input value of current to the coil 51, a control computer 37 performs switching control to switch the on-off switch 40 over alternately between the on and off-positions.

摘要： PROBLEM TO BE SOLVED: To provide a displacement control structure which can invariably keep maximum gradient of a swash plate while avoiding useless constituents. SOLUTION: An abrasion preventive body 29 is fixed to a tiltably supported swash plate 20. Maximum gradient of the swash plate 20 is regulated by abutting the abrasion preventive body 29 against a rotational support body rotated integrally with a rotary shaft 18. The rotary shaft 18 is rotated in the direction of an arrow Q. An attaching position of the abrasion preventive body 29 is set within a discharge processing area De on the swash plate 20 for performing discharging operation by a piston 26.

摘要： PROBLEM TO BE SOLVED: To easily layout variable displacement compressors, whose maximum discharging capacities are different from each other by setting a distance between an inclining center axis of a swash plate and a part abutting on a rotary supporting body in a sleeve, so as to set a maximum inclining angle of the swash plate. SOLUTION: In a variable displacement compressor, a quantity for releasing refrigerant gas from a crank chamber 15 into a suction chamber 32 is regulated, and pressure in the crank chamber 15 is changed by a relation between the releasing quantity and a quantity of delivered refrigerant gas which is led from an air supply passage 38. A difference between pressure in the crank chamber 15 and pressure in a cylinder bore 29 is changed, and the inclining angle of a rotary swash plate 19 is changed, and thereby, the discharged capacity of a compressor is regulated. In this case, in a sleeve 18 wherein the wash plate 19 is journalled via a support pin 20 freely to incline, a distance between an inclining center axis of the swash plate 19 and an abutting part 23a for regulating the maximum inclining angle is set, and thereby, the maximum inclining angle of the swash plate 19 is decided. Namely, the longer the slide movable quantity of the sleeve 18 is, the more gradually reduced, the more the maximum inclining angle of the swash plate 19 is reduced.

摘要： PROBLEM TO BE SOLVED: To prevent crank pressure from increasing more than necessary in advance and to eliminate wasting of high-pressure coolant gas generated by the compressor even when letting a compressor of swash plane type rapidly shift to the minimum capacity operation by increasing the crank pressure in a short period. SOLUTION: In the middle of an intake passage 28 coupling a discharge chamber 22 of a variable capacity compressor of swash plane type and a crank chamber 5, a valve portion 51 in the intake side of an electromagnetic switch valve and gas flow adjusting mechanism 80 are provided in series. The valve portion 51 in the intake side opens and closes the intake passage 28 by external control. The gas flow adjusting mechanism 80 chronologically changes the quantity of passing gas in response to gas supplied from the discharge chamber 22 by an opening operation of the valve 51 in the intake side to adjust the quantity of gas flowing into the crank chamber 5 as time goes by.

摘要： PROBLEM TO BE SOLVED: To prevent disconnection of a connecting part due to thermal expansion in a spacer by connecting a coil terminal to the connecting part to be installed in a terminal, and connecting a coil body and the connecting part to each other via the spacer, while engaging the coil terminal in the midway leading to the connecting part, with an engaging part installed in a terminal base. SOLUTION: In a coil unit 90 of a solenoid for a capacity control valve, a bobbin, a terminal base 93 and an insulating coat 102 expand by the operating heat in the solenoid or the like, thereby a space between connecting parts 94a, 95a and a coil body 92a tends to wider. However, since a coil 92 is made of a metal of a low expansion coefficient, and both the terminals 92b and 92c do not expand in spite of ambient temperature rise a thermal stress generates in resin members 91, 93 and 102, whereby these terminals 92b and 92c of the coil 92 are tensed up. At this time, as the terminals 92b and 92c are rolled on fixed pieces 97 and 98 in the midway leading to the connecting parts 94a and 95a, load acting on these connecting parts 94a and 95a is lightened, thus disconnection is obviated.

摘要： PROBLEM TO BE SOLVED: To reduce any load in the time of starting as well as to facilitate a valve characteristic variation by fully opening this valve in time of nonenergizing of a magnetic coil, making compressor discharge side pressure act on the upper and lower sides of a valve element, and altering the diameter of a compensation pin installed in space between a discharge side pressure inlet port and a pressure sensitive regulator. SOLUTION: In time of nonenergizing of a magnetic coil 15, downward energizing force of a plunger spring 4 working on a valve part 8 is smaller than the upward energizing force of a valve spring 9, so that a valve 1 is fully opened. At that time, a compressor is in a state of full-unload operation, whereby a bellows 11 is contracted, and thus the underside of a valve stem 8b separates from a compensation pin 10. When being energized with current, a connecting rod 6 goes down according to a current value and thereby the valve 1 is closed. Then, compressor discharge side pressure acts on the upper and lower sides of a valve element 8a after passing through an internal equalizing hole 17g, and the valve 1 operates irrespective of a pressure differential between the discharge side of a compressor and the inside of a room. At that time, since the compensation pin 10 makes its compensating froce work on the bellows 11, a diameter of this compensation pin 10 is clanged, thereby changing a valve characteristic.

摘要： PROBLEM TO BE SOLVED: To provide such a power saving control valve for a variable displacement compressor as being capable of holding the valve element at the maximum opening position even under high suction pressure. SOLUTION: To one side of a valve element 64, a movable iron core 79 in a solenoid portion 62 is connected via a solenoid rod 82. To the other side of the valve element 64, a pressure sensitive rod 74 is connected, the end of which is fitted into a pressure sensitive rod bearing portion 71 for a pressure sensitive portion 70 in a pressure sensitive room 68 in a freely slide-contacting manner. The valve element 64 and the pressure sensitive portion 70 are connected together in a mutually approachable/separatable manner. A forcible opening means 65 is provided to forcibly open the valve element 64 with the demagnetization of the solenoid portion 62. The maximum displacement distance in the direction of reducing the opening of an air supply passage for the pressure sensitive portion 70 is formed to be smaller than the maximum fitting distance between the pressure sensitive rod 72 and the pressure sensitive rod bearing portion 71.

摘要： PROBLEM TO BE SOLVED: To provide such a power saving control valve for a variable displacement compressor as being capable of ensuring accurate opening control of the valve with a small solenoid portion while reducing the influence of discharge pressure and pressure in a crank room. SOLUTION: To one side of a valve 64, a plunger 78 in a solenoid room 77 is connected via a solenoid rod 81. To the other side of the valve 64, a pressure sensitive portion 70 in a pressure sensitive room 68 is connected via a pressure sensitive rod 72. The size of a valve hole 66 opposed to the valve 64 is equalized to the size of the solenoid rod 81. One of discharge pressure Pd and pressure Pc in a crank room is introduced to a valve room 63 in which the valve 64 is stored and the other is introduced to the valve hole 66 and the solenoid room 77.
