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： When oil flows from within a seat valve along an oil path in a valve, structure is such that a negative pressure is generated to draw a ball in the direction of the seat valve. That is, the force in the direction of valve closure is actively utilized, the valve does not perform a full stroke in a certain differential pressure range, and increases in a pulsed manner in a minute-stroke state, i.e., in a state where the passage cross-sectional area of the valve is small. Therefore, effective control becomes possible without a large pressure increase.

摘要： A wheel cylinder and brake piston are formed in the brake caliper of each wheel of a vehicle. A piezoelectric device, which is formed of laminated piezoelectric elements, is formed in the brake caliper such that it is connected with the wheel cylinder. By applying a voltage to the piezoelectric elements the piston device is made to expand and contract to thereby vary the volume of the wheel cylinder. Brake fluid is supplied from the master cylinder to the wheel cylinder via fluid passage formed in the brake caliper and a control valve for opening and closing this passage is formed in the passage. When there is a high pressure in the wheel cylinder, the piezoelectric device expands and the control valve closes. Then, by lowering the voltage the piezoelectric device contracts and the pressure in the wheel cylinder decreases.

摘要： A brake system capable of implementing anti-skid and traction control operations has an electromagnetic valve for connecting a master cylinder to a wheel cylinder and for disconnecting the master cylinder from the wheel cylinder when anti-skid or traction control is executed. A piezo-electric hydraulic pump is provided for introducing high-pressure brake oil when anti-skid or traction control is executed. A pressure reduction valve selectively introduces and removes brake oil so that a desired wheel cylinder pressure can be attained when anti-skid or traction control is executed. A hydraulic switching valve is connected to the main oil pressure line parallel to the electromagnetic valve and allows pressure in the master cylinder to be opened to the wheel cylinder during a braking operation. The system also includes a unit for establishing one-way communication from the wheel cylinder to the master cylinder during anti-skid control to prevent pressure in the wheel cylinder from being higher than that in the master cylinder while preventing connection between the master cylinder and the wheel cylinder during traction control.

摘要： A rotary compressor includes a cylindrical-shaped housing, a rotor rotatably mounted in the housing and formed with diametrically extending slits, and a pair of movable vanes each slidably disposed in each of the slits with its opposite ends extending beyond the associated slit in abutting relation to the inner surface of the housing. The clearances between the movable vanes and the slits of the rotor are made larger about the central portion of the rotor than adjacent to the outer periphery thereof by making each of the vanes thinner about its central portion than at its opposite end portions or making each of the slits wider about the central portion of the rotor than adjacent to the outer periphery of the rotor. With the arrangement, shearing stresses caused by shearing of oil in the compressor can be suppressed to thereby reduce a loss in the torque of the compressor, and the maximum stress on the movable vanes can be limited below an allowable stress to improve the anti-breakage characteristics of the vanes.

摘要： A compact, piezoelectrically operated pressure modulator for antiskid control of a hydraulic braking system. In its simplest form, the modulator comprises a body in which are formed a main hydraulic passage adapted to connect the master cylinder to a wheel cylinder, and a pressure relief passage for relieving the pressure in the wheel cylinder. The main passage is opened and closed by a normally open shutoff valve operated by a piezoelectric actuator, and the relief passage is controlled by a normally closed shutoff valve operated by an associated piezoelectric actuator. Adjusting mechanisms are provided to adjust the axial position of the piezoelectric elements of the actuators in such a manner that the valve clearance of the shutoff valves is adjusted to an optimal amount.

摘要： A housing of a brake booster 100 includes a pair of shells 1 and 5 and a ring 3 interposed therebetween which cooperatively define an interior space for accommodating a power piston 13. The interior space is divided into a front chamber 15 and a rear chamber 16 partitioned by the power piston 13. The power piston 13 has a diaphragm 2 interposed between the front chamber 15 and the rear chamber 16. The diaphragm 2 is shiftable in an axial direction thereof in response to pressure imbalance between the front chamber 15 and the rear chamber 16. A convolution chamber 2d is provided between an inner side of the housing and an outer peripheral edge of the diaphragm 2. The convolution chamber 2d is defined by a resilient annular member flattened in the axial direction and isolated from both the front chamber 15 and the rear chamber 16. The annular member elastically rolls along the inner side of the housing in response to pressure imbalance between the convolution chamber 2d and one of the front 15 and rear chambers 16. And, a port 28 is formed in the ring 3 to supply constant pressure into the convolution chamber 2b.
