    Abstract: A fuel injection pump includes a cam rotating with a camshaft, a cam ring revolving around the camshaft, a housing, plungers for pressurizing and pressure-feeding fuel drawn into fuel pressurizing chambers, and a rotary pump for supplying the fuel to the fuel pressurizing chambers. The housing includes a first housing portion for rotatably housing the rotary pump and second housing portions for housing the plungers so that the plungers can reciprocate. A filter is disposed in one of an outlet portion of a first low-pressure fuel passage in the first housing streaming the fuel from the rotary pump toward the fuel pressurizing chamber, an inlet portion of a second low-pressure fuel passage of the second housing portion facing the outlet portion, and a certain point in the second low-pressure fuel passage.

    Abstract: A fuel system 10 which selectively receives, stores and delivers volatile fuel 16. Fuel system 10 includes a variable volume fuel tank 12 having a movable piston 22 which is attached to a pair of bellows diaphragm members 26, 28. Members 26, 28 selectively contract and expand to move piston 22 within tank 12, effective to alter the volume of the fuel containing portion 14 of tank 12, thereby maintaining fuel 16 in a pressurized state and substantially preventing the accumulation of vapors within tank 12.

    Abstract: A motion converting mechanism for converting the rotating motion to the inclined gyration movement in a fuel pump is isolated from gasoline through a flexible isolating member. The lubrication of a load supporting portion in the fuel pump, which is enclosed in an interior portion of the flexible isolating member, can be performed. A sealing portion of a rotating shaft in the fuel pump is isolated from the gasoline by the flexible isolating member. The lubricating oil is sealed in an interior portion of an isolating area formed by the flexible isolating member.

    Abstract: An on-off valve is connected between a high-pressure pump and a low-press pump and is sized to be rapidly activated during the cranking stage of an internal combustion engine. After actuating the on-off valve, surplus fuel is drained into an inner chamber of the high pressure pump. A solenoid valve is further provided between the low-pressure pump and the on-off valve to automatically cut off the supply of fuel to the on-off valve in the event of an engine failure. The apparatus is beneficial to reduce variation in the fuel supply of the low pressure pump during engine start-up and steady-state operation.

    Abstract: A fuel delivery system for an internal combustion engine has a fuel tank with a piston movably mounted on a guide rod therein to separate the tank into two variable volumes, one for containing fuel and the other for containing pressurized air to act on the piston for compressably pressurizing the fuel, thus preventing fuel vaporization during normal fuel delivery. Pressurized air is provided to the pressure volume by an air regulator or a positive displacement pump, either of which can be controlled by a microprocessor based electronic engine control unit. A filler pipe attached to the tank has at least one anti-expulsion valve therein and pressure interlock means for preventing fuel expulsion through the filler pipe when the tank is pressurized. A pressure accumulator is connected to the fuel line to assist in providing a constant fuel pressure to the engine.

    Abstract: The invention relates to a structure of a liquefied hydrogen pump, located within a liquefied hydrogen fuel tank of a hydrogen (gas ignited) engine, in which a cylinder holder is linked to a lower end of the connecting rod which is reciprocated upwardly and downwardly by means of an external driving source via a first universal joint and a cylinder is housed within a piston holding member via each arm of the cylinder holder so as to be enabled to move upwardly and downwardly. A stepped engagement recess is formed in a bottom end portion of a pump housing. A bottom lid of the piston holding member is linked to an engagement rod via a second universal joint, the engagement rod being received by the engagement recess so that a radial displacement of the piston holding member and piston member to the pump housing is permitted and an automatic axial alignment of both piston and cylinder to an axial line 01--01 of the pump housing is carried out.

    Abstract: The roller shaft which actuates a pumping element in a fuel injection pump is secured against unintentional release during transport by elastic elements, preferably spring wire parts, whose one end engages a stationary portion of the fuel supply pump and whose other end engages a recess or cutout in the roller shaft and cooperates with a shoulder or stop therein to prevent unintentional drop-out while permitting a normal reciprocating motion after installation. Suitable openings and grooves provided in the roller shaft guide can hold and orient the spring wire.
