Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A fuel pump apparatus has an electric motor and a regenerative pump having a pump housing and an impeller rotated by the motor shaft journalled by a bearing to the pump housing. The impeller is operative to produce in the pump housing a fluid pressure which is unbalanced in the circumferential direction of the impeller and forms circumferentially unbalanced radially inward forces the resultant force of which is applied through the impeller to a first side of the peripheral surface of the shaft. The discharge port of the pump is open to the interior space within the motor. An opening is formed in the bearing and has an inner end faced to a second side of the peripheral surface of the motor shaft substantially diametrically opposite to the first side, whereby the discharge pressure of the pump is applied through the motor interior space and through the opening in the bearing to the second side of the motor shaft to counterbalance to the resultant force of the circumferentially unbalanced radially inward forces applied to the motor shaft.

Abstract: A seat belt tensioning device having a piston return stop device including a tapered member with an inclined surface rising toward one end which is slidably disposed within an axial hole of a piston and is connected to the piston through a connecting member breakable by a predetermined tension force. The other end of the tapered member is connected with a seat belt. Stopper members are slidably disposed within radial guide grooves of the piston and at their outer ends are slidably in contact with an inner wall of a piston cylinder while their inner ends are in contact with the tapered member.When the tension force of the seat belt reaches a predetermined value at an urgent time, the connecting member is broken and the tapered member is moved within the piston in a direction reverse to the travelling direction of the piston to push the stopper members toward the cylinder wall. Then the outer ends of the stopper members cut into the cylinder wall so that the return of the piston is stopped with certainty.
