Abstract: A fuel injection pump which has a shutoff device for the fuel supply to the pump work chamber, comprising a magnetic valve, which controls an intake bore to the work chamber of the fuel injection pump. The fuel injection pump further has a relief conduit, which is connected by an annular slide on the pump piston with the suction chamber in order to terminate the effective supply stroke of the pump piston. In order to assure reliable shutoff of the fuel supply to the pump work chamber, a check valve is further disposed in the connection between the pump work chamber and the suction chamber, which check valve is closed, during the intake stroke of the pump piston, with the collaboration of the pressure drop from the suction chamber to the pump work chamber.

Abstract: A fuel injection apparatus for supplying fuel to an internal combustion engine is proposed. The fuel injection apparatus includes a pump work chamber enclosed within a pump housing, which work chamber is defined at one end by an axially displaceable and rotatable pump piston. The pump work chamber can be made to communicate, during the intake stroke of the pump piston, with a fuel inlet conduit via an electromagnetically actuatable metering valve and a check valve. The metering valve and check valve are combined into a common valve housing and are disposed in the immediate vicinity of the pump work chamber.

Abstract: A fuel injection pump for self-igniting internal combustion engines is proposed in which a metering piston operates synchronously with the engine and a distributor operates synchronously with a pump piston. During the intake stroke of the pump piston the distributor delivers a metered injection quantity to a work chamber associated with the pump piston, and during the compression stroke of the pump piston the metered injection quantity is distributed through injection lines to the engine injection nozzles. The metering piston is disposed upstream of the distributor so that high pressure conditions do not deleteriously effect the fuel metering. The stroke of the metering piston is adjusted electrically and controlled by a microprocessor unit to which engine operating characteristics are supplied.

Abstract: A fuel injection apparatus particularly suitable for high-powered engines, in which the pressure chamber of the fuel injection valve or valves is relieved of pressure during the pauses between injections by means of a correspondingly controlled obturation mechanism so that, when the valves are not tight, the undesirable injection of fuel during the pauses between injections is substantially prevented.

Abstract: A fuel control device for an internal combustion engine employing a fuel mixture preparation system in which the amount of fuel is set at will and the amount of combustion air is adjusted automatically. In order to provide sufficient air during abrupt and rapid actuations of the fuel control lever, there is provided a hydraulic differentiating mechanism which senses rapid displacements of the fuel control lever and which temporarily opens a channel leading from a source of high hydraulic pressure directly to the servo motor that pivots the air throttle, thereby causing additional opening of the air throttle and an increased rate of air flow. The high pressure channel is closed gradually after the occurrence of the abrupt fuel change.

Abstract: A fuel injection pump for internal combustion engines has a single rotating and reciprocating piston which alternately aspirates fuel from a fuel storage compartment and delivers it under pressure to one of several injection lines. Fuel aspiration takes place through a plurality of fuel channels which terminate in the wall of the pump cylinder and whose termini are opened by appropriate grooves in the piston surface. The individual fuel channels are in mutual communication via one or more connection channels and are also connected to the fuel storage compartment via a suction conduit.

Abstract: A speed regulator for fuel injection pumps of internal combustion engines includes an intermediate lever pivotable about a pin carried by a shaft which is coupled via a head to a fuel quantity adjustment member of a fuel injection pump. The pin is eccentrically disposed in a shaft which fits within a bushing disposed in the housing of the pump. The shaft is acted on by a speed signalling device with speed dependent force against the arbitrarily variable force of a main control spring. A speed signalling device acts on the intermediate lever. A one-armed drag lever, pivotable about the same axis defined by the pin, about which the intermediate lever pivots, may be provided. In this case, the drag lever is acted on by the main control spring, which otherwise acts directly on the intermediate lever. The shaft is guided in a bushing eccentrically inserted in the housing of the pump and is rotatable and arrestable from without. A stop for limiting maximum full load fuel quantity is vertically spaced by the same amount from the fuel quantity measuring member and the speed signalling device.

Abstract: A fuel injection pump having a device for adjusting the injection timing having a work chamber defined by an adjusting piston and communicating via a throttle bore with a pressure source from which the pressure to adjust the adjusting piston is drawn. In order to modify the pressure in the work chamber, the work chamber can be made to communicate via a pressure limiting valve with the relief side of the pump. The control force of the pressure limiting valve is adjustable by means of a stepping motor. An influence on the pressure controlling the adjusting piston is thereby obtained which is restricted to the work chamber.
