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.

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： A valve device including a housing formed with a passage, valve elements for opening and closing the passage, a spring for urging the valve elements, and a controller for displacing the valve elements against the spring force. The spring has at least two deflection modes, one of which shows a larger spring constant than the other deflection mode and appears in one of two valve positions. The controller outputs a relatively large force for displacing the valve elements to the valve position at which the spring is deflected at the larger spring constant.

摘要： A wheel cylinder is formed in the brake caliper for each wheel of a vehicle and brake fluid is supplied from a master cylinder to this wheel cylinder by way of a fluid passage. 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. A control valve is provided in the fluid passage to open and close it to selectively partition off the master cylinder. When the control valve has closed the passage, a voltage is applied to the piezoelectric piston device to expand it and control the pressure acting on the brake piston in the wheel cylinder to vary the braking force.

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 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. A hydraulic chamber is formed in the cylinder chamber on the side of the floating plate opposite to the side on which the first and second groups of elements are provided, and the pressure in this hydraulic chamber pushes the floating plate in the direction of the fixed support member. 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 peripehral 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.
