摘要： An antiskid control device including a main line system for a usual braking operation and a subline system for an antiskid control, in which the flow rate of the subline system is smaller than the flow rate of the mainline system. The main piping system is provided with a cut-off valve which opens at a usual braking operation and closes at an antiskid control. The subline system is provided with a first control valve for opening the subline system and a second control valve for opening or closing the subline system at an antiskid control. The second control valve opens the subline system to supply a small quantity of brake oil to the wheel cylinder, and closes the subline system to release the brake oil in the wheel cylinder to the outside thereof.

摘要： A hydraulic control valve may have a first chamber having an input port, to which an input hydraulic pressure is applied and an output port, and a second chamber having a third port to which a hydraulic control pressure is applied. When a hydraulic pressure below a predetermined level is applied to the first port, the same hydraulic pressure is produced at the second port. When a hydraulic pressure above the predetermined level is applied to the first port, the hydraulic pressure is reduced at a fixed ratio, and thereby a hydraulic pressure lower than the hydraulic pressure applied to the first port is produced at the second port. Thus the hydraulic control valve functions as a proportional valve. When a hydraulic control pressure is applied to the third port, the first and second port are disconnected. Thus the hydraulic control valve functions as a cutoff valve.

摘要： When excessive acceleration slip of a driving wheel is detected by wheel speed sensors attached to driving and non-driving wheels, an electronic control unit provides first and second control signals to a change-over valve and a control valve, respectively. The change-over valve operates in accordance with the first control signal to supply hydraulic pressure from a hydraulic pump to control a cut-off valve to thereby cut off communication between a master cylinder and a wheel cylinder. At the same time, hydraulic pressure from the hydraulic pump is fed to the wheel cylinder through the change-over valve and the control valve to brake the driving wheel. The control valve operates in accordance with the second control signal to increase or decrease the pressure in the wheel cylinder thereby adjusting the braking force for the driving wheel.

摘要： A brake control system for effectively properly performing a braking hydraulic pressure distribution between a front wheel and a rear wheel or a left wheel and a right wheel of a motor vehicle including a master cylinder for generating a hydraulic pressure in response to depression of a brake pedal thereof and applying the hydraulic pressure through first and second braking passages to first and second wheel braking cylinders. This brake control system has first and second pressure control devices respectively coupled to a braking pressure source for allowing the output hydraulic pressures to be regulated independently of each other under control of a control unit. The output of the first pressure control device is coupled through the first braking passage to the first wheel braking cylinder and the output of the second pressure control device is coupled through the second braking passage to the second wheel braking cylinder. The control unit determines first and second target braking pressures to the first and second wheel braking cylinders on the basis of the hydraulic pressure in the master cylinder. The determined first and second target braking pressures are respectively corrected on the basis of the vehicle acceleration and wheel slip ratios.

摘要： A piston in a first cylinder is driven as a piezoelectric element group, which includes a plurality of laminar piezoelectric elements stacked in layers, extends or contracts. A second cylinder is formed so as to connect with a first fluid pressure chamber which is defined in the first cylinder by the piston. A piston-shaped valve member is disposed in the second cylinder. The valve member is urged toward the first fluid pressure chamber by a spring. The first fluid pressure chamber is supplied with a fluid whose pressure is set by means of a selector valve. When the selector valve is closed, the fluid pressure chamber is defined as an independent compartment. In this state, high voltage is applied to the piezoelectric element group to elongate it, thereby driving the piston. Thus, the valve member is actuated by the fluid pressure inside the first fluid pressure chamber, and a fluid passage is opened and closed by the valve member.

A brake piston is provided inside the wheel cylinder and includes a piezoelectric piston device inside. By the application of voltage, this piezoelectric piston device expands and contracts the brake piston.

摘要： A floating plate is provided in a cylinder chamber and slides freely like a piston. A first group of laminated, ring-shaped, thin-plate piezoelectric elements is provided between a fixed support member provided on part of a wall portion of this cylinder chamber and the floating plate. A second group of laminated, cylindrical, thin-plate piezoelectric elements is provided in the center of the first group and a working member is provided on the free end of the second group of elements that is not attached to the floating plate.

Voltage is applied to the first and second groups of elements to expand and contract them thereby varying the distance between the floating plate and the fixed support member and varying the distance between the floating plate and the working member.

摘要： A rotary piston vacuum pump has a rotor eccentrically disposed in a cylinder and mounted therein for revolution in rolling contact with the cylindrical inner peripheral surface of the cylinder so that a crescent-shaped space is defined between the rotor and the cylinder and moved around the axis of the cylinder. A vane is radially reciprocally mounted in a vane chamber having an inner end open to the cylindrical inner peripheral surface of the cylinder. The vane has an inner end in sliding contact with the outer peripheral surface of the rotor to divide the crescent-shaped space into a suction chamber in communication with a suction port and a discharge port to be communicated with a discharge port having an inner end open in a wall of an outer part of the vane chamber. The rate of communication between the discharge port and the discharge chamber through the outer vane chamber part is varied by the reciprocal movement of the vane so that the communication is interrupted at least when the point of contact between the rotor and the cylinder inner peripheral surface reaches the vane.
