    摘要： A fuel pump includes rotors that rotate, a pump housing that defines a rotor housing chamber that rotatably houses the rotors, and an outer circumferential side housing that includes a cylindrical portion formed in a cylindrical shape that surrounds the pump housing from an outer circumferential side and a narrowing potion having that narrows down with respect to the cylindrical portion. The fuel pump sucks fuel into the rotor housing chamber and then discharges the fuel due to the rotor rotating. A pump cover of the pump housing includes an inlet port that sucks fuel into the rotor housing chamber, and a sliding surface portion on which the rotors slide. An outer circumferential portion of the pump cover includes a joining portion joined to the narrowing portion, and a recessed portion that is recessed adjacent to the joining portion, the recessed portion allowing the outer circumferential portion to elastically deform.

    摘要： A fuel injection device for smooth discharge of a gas accumulated therein comprising a fuel pump, a solenoid valve for injecting pressurized fuel into the intake passage of an engine, a high-pressure fuel passage extending from the fuel pump to the solenoid valve and has a medially positioned constant-pressure chamber, and a fuel return passage connected to a fuel return pipe, with the fuel return passage extending from the constant-pressure chamber and having a medially positioned priming pump. The constant-pressure chamber is configured with the top wall in the upper space thereof disposed above the opening of the high-pressure fuel passage opposite the solenoid valve, the fuel return passage opens into the upper space at a position above the opening of the high-pressure fuel passage, and the gas accumulating in the constant-pressure chamber is discharged from the upper space toward the fuel tank via the fuel return passage.

    摘要： A closed loop fuel supply system for operating engines in all possible attitudes in which fuel is delivered by a vacuum pump responsive to the vacuum level in the crankcase of the engine and in which the vacuum driving the pump is modulated in response to the pressure of fuel being delivered to the fuel supply system so that the amount of fuel delivered for combustion purposes is equal to the requirements of the engine without any excess. In another embodiment, the delivery of pulsating fuel is dampened to obtain a uniform fuel delivery and distribution to the combustion chamber is under the control of three shutoff valves operating throughout the speed range of the engine. In each embodiment fuel is conserved and a fuel return line is not required.

    摘要： An improved multicylinder internal combustion engine is described for efficiently producing power. The internal combustion engine described is fuel injected with a stoichiometric fuel mixture to develop a stratified charge suitable for igniting a leaner mixture of fuel and air. The charge is advantageously introduced into two adjacent cylinders for igniting a fuel mixture common to both cylinders. Improved fuel injection and super charging of the internal combustion engine is also described herein.

    摘要： In a fuel injection pump of the type having a pump membrane which, by virtue of its oscillation caused by the pulsating pressure in the crank case of the associated internal combustion engine, delivers fuel under pressure to a fuel injection nozzle for injection into the air intake tube of the engine, there is provided a manually operable primer pump for driving an initial fuel quantity to the injection nozzle and a manually adjustable bias control means for arbitrarily changing the closing force exerted on the outlet valve of the pump. The said bias control means is a unitary structure so designed that, first, a permanent fine adjustment may be effected in a stepless manner to set the exact metered fuel quantities for normal engine operation and, second, a temporary decrease in the bias force map be brought about to effect an increased fuel delivery (enriched air-fuel mixture) during the cold starting of the engine.
