摘要： Around an engine-body of a vehicle, several auxiliary machinery such as an air-conditioner and a power steering-pump are disposed. Pulleys of said auxiliary machinery are driven by means of an endless belt or endless belts by a driving pulley of the engine. In order to obtain the most effective operation of the engine, consideration should be given to the degree of the power loss for driving the auxiliary machinery.For this purpose, according to the present invention, the order by which said several driven pulleys are driven by said driving pulley is determined by the magnitude of the driven torques of the corresponding auxiliary machinery along the running direction of the endless belt toward the driving pulley.

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.

摘要： A fuel filter device for use with diesel engines has a manually operable pump section and a filter container housing therein a filter element and detachably attached to the pump section. The pump section has a manually operable diaphragm facing a chamber having fuel inlet and outlet respectively communicated with a fuel tank and the filter container. The inlet and outlet are provided with valves responsive to the fuel pressure at the inlet and to a pressure variation caused by the diaphragm in the chamber to allow the fuel to flow through the inlet into the chamber and through the outlet into the container in which the fuel flows through the filter element and out of the container to a discharge port of the pump section. An electric heater is disposed in the chamber adjacent to the path of the flow of the fuel in the chamber. A fuel temperature or pressure sensor is disposed downstream of the filter element to provide a signal for the control of the electrical supply to the heater.

摘要： A filter element for straining liquid formed of a filter material in a convoluted form including two portions, one portion being a planar portion and the other portion being a corrugated portion having a plurality of elevated areas. The filter material is foled in half in the longitudinal center and wound in convolutions so that a series of letters V are formed on a transverse cross-sectional surface thereof. The pitch of the elevated areas is smaller in the central portion of the convoluted filter element corresponding to the end of the filter material at which winding is started and larger in the outer peripheral portion thereof.
