摘要： An exhaust gas recirculation apparatus for diesel engines includes an exhaust gas recirculation passage for recirculating exhaust gases from an exhaust pipe to an intake pipe, a valve body for controlling the cross sectional area of the recirculation passage and a pressure regulator for detecting an amount of fuel injection and to output a signal. A diaphragm device is operatively connected to the pressure regulator to receive a pressure signal to control the position of the valve body, whereby in response to an increase of fuel injection the cross sectional area of the recirculation passage is decreased.

摘要： An optical velocity measuring apparatus applicable to measurement of the velocity of a vehicle relative to the road. A pair of light sensors mounted on the bottom of the vehicle body spaced from each other in a direction of the movement of the vehicle respectively receive rays of light reflected from different spots on the road through an optical system and produce electric signals indicative of the surface conditions of the spots. A time lag from the detection of a particular spot by the forward light sensor until the backward light sensor detects the same spot is measured to determine the velocity of the vehicle. The optical system is comprised of first and second lenses each having a peripheral portion cut away by a plane parallel to the optical axis. The first and second lenses are aligned so that the cut away faces are in contact with each other and that the optical axes are in parallel to and spaced a predetermined distance from each other.

The compressor has a front and rear rotor 6a and 6b for defining, together with a cylinder bores 43 and 44, first and second operating chambers 39 and 40, respectively. A refrigerant from a first inlet opening 28 is sucked into the first operating chamber 39 by a rotation of the front rotor 6a for obtaining a first stage compression at the first chamber 39. The refrigerant is then introduced, via an intermediate pressure chamber 36, to the second operating chamber 40 for obtaining a second stage compression at the second chamber 40, which is discharged outwardly.

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 vane type pump having a housing formed with an inlet chamber and an outlet chamber and having a cylinder portion, a cylindrical rotor mounted for eccentric rotation in the cylinder portion, and a plurality of vane mounted for concentric rotation in the cylinder portion. The rotor is formed with slots through which the vanes extend into a space defined between the inner peripheral wall of the cylinder portion and the outer peripheral wall of the rotor so as to divide the space to define a working chamber variable in volume for pumping effect. The inlet chamber is associated with the cylinder portion to define a fluid confinement initiating line at which the working chamber begins to be isolated from the inlet chamber when the forward end of one of the vanes passes the line. The fluid confinement initiating line is in a symmetrical inclined configuration such that the line is generally symmetrical with respect to the widthwise center line of the cylinder portion and is inclined with respect to the longitudinal axis of the cylinder portion over the substantially entire length of the line beginning at opposite ends of the cylinder portion.
