摘要： PURPOSE:To enable high precision adjustment of mechanical operating force by mounting a controlling means which receives the converted electric signal from a detecting electrostrictive element to control the electric power to be supplied to a laminated unit and adjusts the mechanical operating force generated therefrom. CONSTITUTION:With a set 11 of laminated electrostrictive elements 11 expanded, the oil pressure in a cylinder operates on a detecting electrostrictive elements so that said elements 15 generates the electric capacity changing signal having an extremely trifle value of hysterists. Next, the detecting signal from the detecting electrostricitive element 15 is converted to a voltage signal by a capacity to voltage converter 24 and a deviation detector 26 generates a deviation signal according to a deviation between the target value from a target value calculating circuit 25 so that the voltage generated by a voltage increasing and decreasing circuit 27 is increased and decreased according to the deviation signal and a driver 28 applies the driving power to the set 11 of the laminated electrostrictive elements. When the generated power reaches the target value, the output voltage of the circuit 27 becomes constant to maintain the target driving force, whereby executing the precise control of the driving force.

摘要： PURPOSE: To determine an optimum vehicle controlling requirement before the traveling on a circuit course for reproducing it accurately during the traveling. CONSTITUTION: A circuit course is divided into a plurality of straight and corner parts respectively as units, and a distance-division table is stored so that the position of a vehicle can be recognized on the basis of the distance from a start-finish line. Also, the traveling distance of the vehicle is calculated (S1) while the traveling distance is cleared to 0 according to a signal from a trigger signal unit provided on the start-finish line. On which division on the circuit the vehicle is traveling is judged by the table on the basis of the traveling distance (S2). A map MFSEGTP to obtain a correction factor FSEGTP based on the division of a fuel injection amount according to the division is determined (S3). The FSEGTP is calculated from the map MFSEGTP in the corresponding division on the basis of intake pressure PM and rotational frequency of an engine NE (S4).

摘要： PURPOSE:To achieve a highly accurate control by controlling the restricting quantity of a variable restrictor by means of a member responsive to the temperature of fluid to be delivered from a pump. CONSTITUTION:Actuators 3, 4 for controlling the eccentric quantity are provided to a variable capacity oil pump 1 while a variable restrictor 10 is provided in a delivery oil path 9. The restricting quantity of the variable restrictor 10 is controlled by means of a temperature responsive member 16 and when the temperature of the delivery fluid is high, a thermo wax 18 is fused to push a spool 12 to the left so as to reduce the restricting area. It will function reversely when the temperature is low. Consequently, the variation of the differential pressure across the restrictor due to the variation of the viscosity caused by the temperature variation can be corrected.

摘要： PURPOSE:To ensure automatic reversing of a vane body by providing a spill passage, which connects a pressure chamber on the high pressure side to the low pressure side when a shaft-shaped valve body is in the neutral position, to a lower plate. CONSTITUTION:A spill passage 35 is formed at the reversing position of a vane body 20 (corresponding position to the neutral position of a shaft-shaped vane body 28) of a lower plate 13, or at the part at which the end part of an arm 24 of the vane body 20 is situated. As a result, when the vane body 20 comes to the reversing position, a pressure chamber A, which is on the high pressure side, is connected to the low pressure side via the spill passage 35, thereby lowering the pressure in the pressure chamber A. Thus, pressure differential acting on the shaft-shaped valve body 28 is lessened. Accordingly, every time the vane body 20 is reversed, the pressure acting on the vane body 20 can be surely switched, and automatic reversing of the vane body 20 can be ensured.

摘要： PURPOSE:To enhance the automatic reversing performance of the captioned motor by extending in the circumferential direction the part, which abuts on a shaft-shaped valve body of a vane body, so that the vane body is formed into an anchor shape. CONSTITUTION:A rod part 23 is provided in a radial and in an extended manner at a cylindrical, base part 21, which is fixed to the outer periphery of a revolving shaft 17, and an arm part 24 is provided in the circumferential direction at the tip end of the rod part 23, so that a vane body 20 is formed into an anchor shape. Thus, a shaft-shaped valve body 28 can be shortened by the length of the arm part 24 of the anchor-shaped vane body 24 and the oscillating angle theta of the revolving shaft 17 can be kept at the same angle as before. As a result, pinching force and deformation, both of which are caused by the unbalance in the oil pressure, can be reduced even at the time of a high load. Accordingly, sliding performance can be enhanced, and good, automatic reversing performance can be ensured even at the time of a high load.
