摘要： PURPOSE:To obtain the energy economization type device by reducing the consumed electric power of a hydraulic pump by varying the discharge quantity by controlling the suction quantity of the hydraulic pump according to the variation of the pressure in a discharge passage, by a flow rate control means. CONSTITUTION:When a hydraulic system 9 does not require flow rate, in other words, the line pressure PL is over a prescribed value, the line pressure PL is held at a constant value by a relief valve 4. While, on a suction passage 5 side, a flow rate control means 3 is held in the direction for reducing the suction quantity of a hydraulic pump 2 side to the min. Therefore, the discharge quantity of a hydraulic pump 2 is reduced to the min., and also the consumed electric power can be reduced to the min., and the energy economization can be realized. In this state, if the hydraulic system 9 requires flow rate, the line pressure PL is reduced, and the line pressure PL acts onto the flow rate control means 3 through a pilot passage 7a, and said means 3 is moved in the direction for increasing the suction quantity of the hydraulic pump 2, and the flow rate control means 3 holds the line pressure PL at a prescribed value.

摘要： PURPOSE:To prevent the generation of transmission gear noise during no-load running, by combining together a cut valve, opening and closing an oil passage running from a clutch master cylinder to a clutch release cylinder, an oil pressure producing source, a piston, feeding pressure oil, and a solenoid valve, controlling the piston. CONSTITUTION:A case 22a, to which a pin 22d, a ball valve 22e, and a spring 22f are mounted, is mounted in a body 21 through a spring 22b. A pin 22d is forced into contact with a stopper pin 22c to open an oil passage P1. When an oil pressure is introduced in an oil chamber R, a piston 23 is moved, the ball valve 22e is seated to a valve 22a2 to close the oil passage P1, and pressure oil is fed from an oil chamber R0. When a car speed is 1, a transmission gear 13 is neutral, and a clutch pedal 10 is not stepped on, a solenoid 30 introduces an oil pressure, fed from a power source 40, to the oil chamber R0 to close the oil passage P1. A clutch is disengaged by a clutch release cylinder 15 by means of an oil pressure, and noise of the transmission gear 13 can be prevented from generation.
