摘要： PURPOSE:To enable continuous displaying of the discharge capacity near to a true value by providing a display means displaying according to the output of a detection means for electrically detecting the rotational angle of a control plate. CONSTITUTION:When a control plate 13 rotates, the peripheral directions of notch members 17, 18 vary. The position where communication between a compression chamber formed by means of a vane or the like and an intake hole 19 is shut out, namely the position where a compressor starts operation, continuously varies, and the discharge capacity is continuously controlled. A resistance wire 21 for a potentiometer is adhered by means of an adhesive agent in the vicinity of a notch part 17 of the control plate 13. Hence, when the plate rotates, the output resistor value of the wire varies, and the display value, therefore, varies according to the fIuctuation.

摘要： PURPOSE:To secure such a displacement controlling mechanism that is high in reliability, by forming a seal groove in both inner and outer circumferential surfaces of a control member, in the case of the displacement controlling mechanism that rotates the control member according to differential pressure between two chambers capable of varying each pressure and varies an opening angle of a bypass port. CONSTITUTION:Each pressure receiving member 26 is being housed in two sector-form pressure operating chambers 27 formed in a rear side block 9, and a control member 24, which controls the pressure receiving member 26 and an opening angle of the bypass port connected to this member 26 by differential pressure between a first chamber 271 and a second chamber 272 partitioned off by the pressure receiving member 26, is constituted so as to be moved. Since a seal member 31 is installed in fitting grooves 33 and 34 on both inner and outer circumferential parts of the control member 24, width of the pressure receiving member 26 is widened up to its full extent of the control member 24 so that a pressure receiving area of the member 26 is increasable. With this constitution, driving torque of the control member 24 is increased, and hystereis is restrained, thus controllability is improvable.

摘要： PURPOSE:To secure such a variable displacement controlling mechanism that is simple in structure and high in reliability, by rotating a control member according to differential pressure between two chambers capable of varying each pressure, and controlling compression starting time in a way of varying an opening angle of the bypass port formed in the control member. CONSTITUTION:Two sector-form pressure operating chambers 27 are formed in a rear side block 9, and a pressure receiving member 26 is housed in the inner part. A first chamber 171 and second chamber 272 are formed in the pressure operating chamber 27 partitioned off by the pressure receiving member 26, and pressure in both these chambers acts on both sides of the pressure receiving member 26. In the second chamber 272, there are provided with a low pressure interconnecting passage 28 and a high pressure interconnecting passage 29 to be selectively interconnected to a low pressure side chamber 17 and a high pressure side chamber 19 via a valve mechanism 33, and when this valve mechanism 33 is selected, pressure in the second chamber 272 is varied to some extent, whereby the pressure receiving member 26 is moved by differential pressure. Since the pressure receiving member 26 is connected to a control member controlling an opening angle of a bypass port, displacement of a compressor is controlled by movement of the pressure receiving member 26.

摘要： PURPOSE:To save power and suppress fuel consumption in an arrangement where the idling speed is increased during operation of the compressor for a car cooler by disengaging the speed increase operation while the engine speed is over a certain specified value. CONSTITUTION:A pulsed output generated on the basis of On/off repetition with a contact point 4 during a car being in service is put into a comparator circuit 30 by obtaining an output voltage E proportional to the number of revolutions of the engine by means of passing through a frequency voltage converter circuit 5. The comparator circuit 30 now compares the abovementioned voltage E with the set voltage E1 using a operational amplifier 31, where the output of this operational amplifier 31 will become 'L' for E>E1 and the transistor 37 in the output circuit 36 is put off. Accordingly the contact 41 of relay 42 is put off to stop the idling speed increase device 44 in connection parallelly with a magnet clutch 43 to drive the compressor. Thus speed increase operation of the engine is released.

摘要： PURPOSE:To improve volumetric efficiency by providing suction passages to make a swash plate chamber and a compression chamber communicate with each other when a piston reaches the vicinity of the bottom dead point so that a medium to be compressed is sucked-in also from the swash plate chamber side in the final suction stroke. CONSTITUTION:Suction passages 21a and 21b are provided in cylinder blocks 3a and 3b. One ends thereof are opened in a swash plate chamber 4, and the other ends in cylinder bores 10a and 10b so as to make the swash plate chamber 4 and a compression chamber 18a or 18b communicate with each other when a piston 7 reaches the vicinity of the bottom dead point. Accordingly, when the piston 7 reaches the vicinity of the bottom dead point, the suction passage 21b is opened, and because the pressure in the swash plate chamber 4 is higher than that in the compression chamber 18b, a coolant gas is sucked into the compression chamber 18b by the pressure difference. Thereby, when the piston 7 reaches the bottom dead point, the gas is sucked-in also from the side of the swash plate chamber 4. Accordingly, volumetric efficiency can be improved, and discharge quantity is increased.
