Abstract: A fuel supply system with two series-connected pumps and fuel injection valves that inject fuel directly into a combustion chamber of an engine. The system includes a relief device. In a simple embodiment, the relief device can assure that the pressure in the pressure line can drop when the engine has been shutoff. The relief line may, however, also be embodied such that during the entire time of engine operation, the pressure in the pressure line can be lowered at any time as needed. The apparatus and the method are intended for an internal combustion engine of a vehicle.

Abstract: A piston pump for pumping fuel in which a risk of fuel getting into the area of a shaft seal is limited. The fuel pump includes a separation chamber which is provided between a shaft seal and a fuel chamber that contains fuel. Located in the separation chamber is for instance air as a separator means, and the separation chamber communicates with an air inlet of the engine. This assures that fuel cannot get into the area of the shaft seal or escape to the outside. The fuel pump is suitable in particular for internal combustion engines in which the fuel must be delivered at high pressure.

Abstract: A fuel injection system, for internal combustion engines in which fuel is brought to high injection pressure and distributed via magnet valves to the various fuel injection locations with the aid of a simple, unregulated high-pressure injection pump; high-pressure injection does not take place until a fuel injection quantity control valve, connected to the distribution of the high-pressure side, has closed a relief line. It thus becomes possible to vary the injection time to the maximum possible extent, without entailing major structural expense.

Abstract: A hydraulic engine valve control having a reservoir chamber, which is assigned to a pressure chamber of a valve tappet and has a reservoir piston, which at the same time serves as a valve by which the reservoir chamber can be disconnected from the pressure chamber. The reservoir piston is displaceable out of its position of repose into its reservoir function by a hydraulic control device that cooperates with a magnet valve. In this process, it is also attained that a plurality of valve control units of one internal combustion engine can be controlled via a single magnet valve, if their various control times do not overlap.

Abstract: In a reservoir-type fuel injection system, fuel can be supplied under pressure by a charge pump to two separate pressure reservoirs and the pressure reservoirs communicates via separate valve assemblies with injection nozzles via lines. By means of the separate reservoirs, overlapping of pre-injection and main injection events in different cylinders can be avoided.

Abstract: Fuel injection nozzle for internal combustion engines, in which a pre-injection is effected with directed fuel sprays and then a main injection is effected with an additional fuel umbrella spray. The individual phases are to run in exact timed sequence and the main injection is to be separated from the pre-injection by way of a pressure step. For this purpose, a valve sleeve (34) is placed on a valve needle (18) which opens in the flow direction of the fuel and is provided with a closing head (20), the valve sleeve (34) being pressed, according to the invention, by an additional spring (50) against the closing head (20) with which it controls an annular valve gap for the umbrella spray. The valve sleeve (34) is also provided with lateral spray openings (62) through which the directed sprays exit during the pre-stroke in which the valve sleeve (34) moves with the valve needle (18) under the influence of the additional spring (50). After the pre-stroke, the valve sleeve (34) is prevented from further movement, so that the additional spring (50) is neutralized and the valve gap is opened for the umbrella spray.

Abstract: An electrically controlled fuel injection pump for internal combustion engines, in particular for direct fuel injection in engines having externally supplied ignition contains a plurality of pump pistons driven by a single common cam. The pumping quantity of fuel is delivered by pumping pistons is controlled via a rotary slide valve to the injection nozzles at the injection sites of the engine, wherein the quantity control is effected by an electrically controlled valve. An axial conduit of the rotary slide which discharges into control bores or control grooves distributed over the circumference of the rotary slide and cooperates with the pump work chamber and the pressure lines to the injection sites and is adjoined by at least one further control bore or control groove which communicates with a pressure reservoir. By this means, a preinjection, separate from a main injection, is made possible at the top dead center charge change.

Abstract: To reduce the construction expense and the space required for a fuel injection pump for supplying a plurality of cylinders of an engine, in particular an internal combustion engine having externally supplied ignition, a fuel injection pump including a drive shaft with a single common cam drives a plurality of pump plungers. The supply quantity is controlled via a rotary slide and a subsequent common distributor delivers the fuel to the injection nozzles at the injection sites of the engine. The quantity of fuel injected is effected by an electrically controlled valve seated in a relief line that branches off downstream of the rotary slide, which by closure of the relief line determines the injection phase.
