Abstract: In a fuel injection apparatus a fuel metering valve is controlled by an air sensor disposed in the air intake tube of an internal combustion engine for metering fuel quantities that are proportionate to the intake air quantities. The pressure difference across the fuel metering valve is varied as a function of at least one engine variable in a hysteresis-free manner by means of an electromagnetic system including a coil armature and a permanent magnet.

Abstract: In a fuel injection apparatus there is provided an air sensor which, as a function of the intake air quantities flowing through the suction tube causes movement of a fuel metering or control plunger. The return force exerted on the air sensor and opposing the force of the air flow is supplied by fuel pressure that is variable by a valve which is set by the interaction of the following forces: the difference between the air pressure upstream and downstream of the air sensor, the fuel tank counterpressure and a spring, the force of which is changeable as a function of engine variables.

Abstract: In a fuel distributor - in which the fuel to be delivered to a cylinder of an internal combustion engine is dosed by a metering valve - in order to maintain at a constant value the difference between the fuel pressure upstream of and downstream of the metering valve, there is provided a plurality of control valves (one for each cylinder) each having a flat seat whose flow passage section is variable by a movable membrane. One side of said membrane is exposed to the downstream fuel pressure urging said membrane into a control valve opening direction, the other side of said membrane is exposed to the upstream fuel pressure urging said membrane into a control valve closing direction. The membrane is so constructed that temperature fluctuations do not affect its tension.

Abstract: The supply of fuel to an internal combustion engine is controlled by a sensor plate mounted in the suction duct and which deflects in response to air intake rate into a conically flared duct portion. The plate is mounted on a pivoted arm, on which is pivotably mounted a rocker engaging the slider of a fuel measuring distributor valve. Pivotal movement of the arm causes a roller to sense a cam surface and adjust the rocker. The cam surface is movable in response to an engine operating condition to provide different relationships.

Abstract: In a fuel injection apparatus of the type that is associated with a gas turbine-type vehicle power plant, there is provided a differential pressure valve which is disposed in the fuel path and which ensures a constant pressure drop across a fuel metering valve regardless of the fuel quantities metered thereby. In order to reduce the back pressure effect of the fuel on the operation of the differential pressure valve, the stationary flat valve seat of the latter has, instead of one, a plurality of fuel flow openings, so that the pressure cross section for any given opening cross section is reduced with respect to known differential pressure valves.

Abstract: In a fuel injection system, in order to prevent an intake air sensor to transmit those forces to a fuel control valve which are generated upon sudden thrusts of air in the engine intake tube, there is provided a valved passage which connects intake tube portions upstream and downstream of the intake air sensor and which opens in response to a predetermined pressure differential prevailing across the intake air sensor.
