摘要： PURPOSE:To enable the sliding surface of a booster to be certainly lubricated by driving the piston of a pressure transformer by means of primary liquid delivered in a boosted state from the booster in order to deliver secondary liquid supplied into the barrel of the pressure intensifier. CONSTITUTION:When a selector valve 7 is switched in order to supply pressure oil to a booster 1 by a pump 6, the operating fluid supplied in advance to a small chamber 4 from a primary liquid tank 5 is intensified in its pressure in order to be supplied to the primary liquid port 19 of a pressure transformer 13. The pressure transformer 13 delivers washing water as secondary liquid by the above mechanism. However, since pressure oil supplied to the booster 1 as well as the primary liquid delivered therefrom are operating fluids with high lubricity, even if the primary liquid leaks to a sliding surface by pressure differential due to pressure intensification, the sliding surface is enabled to be certainly lubricated.

摘要： PURPOSE:To aim at compacting a compressor as well as reducing its weight by providing a control member for controlling discharge capacity and using a coil spring disposed along the rotating direction of the control member as a spring member. CONSTITUTION:A control member 23 controls discharge capacity being rotated normally/reversely between the partly busy position with the latest compression starting time and the busy position with the earliest compression starting time. The control member 23 is pressed to the partly busy position side by the resultant force of the energizing force of a spring member 27 and low pressure and to the busy position side by high pressure respectively. A coil spring 27 disposed along the rotating direction of the control member 23 is used as the above-mentioned spring member. An axial space for accommodating the coil spring can be thus cut down, and a compressor can be compacted as well as its weight can be reduced.

摘要： PURPOSE:To aim at improving the accelerating performance of a vehicle and preventing the delivery temperature from rising so as to inhibit vibration and noise by providing a control pressure adjusting pore for communicating the high pressure chamber and the bottom part of a vane groove. CONSTITUTION:When a vehicle is suddenly accelerated or started, the rotating speed of a compressor rises rapidly and a change-over valve mechanism 32 opens a valve so that the fluid pressure of control pressure Pc flows out to the suction chamber 232. When a control member 24 is in the busy position, the fluid pressure of the control pressure Pc is liberated into a back pressure chamber, and as the control pressure Pc in the high pressure chamber 232 is preset to be low compared to the delivery pressure Pd by way of preparation for the inversion to the partially operating position, the control member 24 is rapidly rotated from the bush position to the partially operating position. Moreover, when the control member 24 moves from the partially operating position to the busy position, the impact generated by the collision between a pressure receiving part and a stopper is lessened due to the small pressure difference between the high pressure chamber 232 and the low pressure chamber 231. At the time of partial operation, the pressure in the high pressure chamber 232 is preset to be intermediate between the delivery pressure Pd and the vane back pressure Pk, which results in the decrease in the cooling medium gas quantity to slip out to the low pressure side and the lowering of the delivery temperature.

摘要： PURPOSE:To aim at improving the accelerating performance of a vehicle and inhibit vibration and noise generated by the rotation of a control member by providing a pore for lowering control pressure when the control member is rotated from the partially operating position to the vicinity of the fully operating position. CONSTITUTION:When a vehicle is suddenly accelerated or started, the rotating speed of a compressor rises rapidly, and a change-over valve mechanism 32 opens the valve, so that the fluid pressure of control pressure Pc flows out to the suction chamber side 11 through a passage 31 from a high pressure chamber 232. At a fully operating time, the fluid pressure of the control pressure Pc is liberated into the suction chamber 11 through a pore 36, and as the control pressure Pc in the high pressure chamber 232 is preset to be low compared to discharge pressure Pd by way of preparation for the inversion to the partially operating position, a control member 24 is rotated rapidly from the fully operating position to the partially operating position. Moreover, when the control member 24 is shifted from the partially operating position to the fully operating position, the fluid pressure of the high pressure chamber 232 escapes into the suction chamber 11 through the pore 36 while a pressure receiving part 26 reaches a stopper and the control pressure Pc of the high pressure chamber 232 is lowered compared to the discharge pressure Pd, so that the impact generated by the collision between the pressure receiving part and the stopper can be lessened.

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 enhance the efficiency of the captioned equipment, by detecting the right-and-left deviation of a plunger and controlling the discharge of a booster pump in correspondence to the amount of deviation thus detected. CONSTITUTION:Discharge pipe passages 39 and 40 for high pressure pumps 35 and 36 are connected to primary liquid chambers 9 and 10 of a booster 1, while displacement sensors 33 and 34, which detect the deviation of a plunger 6, are installed to a large-diameter cylinder part 3. According to the outputs from these displacement sensors 33 and 34, the discharge of either one of the high pressure pumps 35 and 36 is increased, while the discharge of the rest of the high pressure pumps 35 and 36 is decreased. With this contrivance, when the position of the plunger 6 is deviated toward the right or left side from its mid-position because of fluctuation in the charge from both high pressure pumps 35 and 36, the deviation of the plunger 6 can be corrected. Therefore, an escape of the primary liquid from a stroke limiter of the booster 1 can be eliminated, thereby enhancing the efficiency.
