Abstract: In fuel delivery systems with two fuel pumps connected in series, two fuel distribution strips are provided in V-engines. Before now in this connection, there was the problem that in order to regulate the pressure in the two fuel distribution strips, a considerably high cost was required and/or the regulation of the pressure could not take place with the desired quality. In the fuel delivery system proposed here, a favorable pressure regulation in the two fuel distribution strips (21, 22) can be achieved by means of the one pressure control valve (30), with a minimum of rigid lines to be laid. The fuel delivery system is provided for an internal combustion engine of a vehicle.

Abstract: A fuel delivery systems with first and second fuel pumps connected in series in which, a satisfactorily precise regulation of the fuel quantity supplied by the second fuel pump is possible. In particular, a switching time of a control valve that controls the fuel quantity is very short. The control valve includes an electromagnet which holds the valve member in a starting position. The electromagnet is supplied with just enough current that the valve member remains in this position. A slight change of the current supply of electromagnet can then cause the switching of the control valve into the end position within an extremely short period of time. The fuel delivery system is provided for an internal combustion engine of a vehicle.

Abstract: An injection valve is described, in particular for direct injection of fuel into a combustion chamber of an internal combustion engine, with a valve body having a valve opening surrounded by a valve seat to form a spray opening, and with a valve needle which is pressed into its closed position, has a closing head and extends through the valve opening so that the closing head which works together with the valve seat is in contact with the valve seat on the spray side when the valve is closed. To ensure accurate fuel metering that is constant over a long period of time with such an injection valve, a plurality of fuel channels distributed around the periphery are arranged in the flow path upstream from the spray opening so that streams or strands of fuel coming out of the fuel channels are essentially maintained until downstream from the spray opening, and the individual cross sections of the fuel channels (29, 29', 29") together define a cross section of the flow path through the valve which determines the flow rate.

Abstract: A fuel injection valve, particularly an injection valve for fuel injection equipment of internal combustion engines, having a pump piston that can be activated using a piezoelectric or magnetostrictive actuator for exerting a translatory pump motion. A spray-discharge nozzle with at least one spray-discharge opening is hydraulically connected via a fuel pressure line to the pump piston. The spray-discharge nozzle opens when the fuel pressure produced by the pump piston in the fuel pressure line exceeds a predetermined threshold. In the fuel pressure line, at least one non-return valve is arranged so that it opens in the direction towards the spray-discharge nozzle and closes in the opposite direction.

Abstract: A fuel supply systems with two series-connected pumps and with fuel injection valves that inject fuel directly into a combustion chamber of an engine in which a starting process takes less time because of the small feed quantity of the second fuel pump. The system includes a valve device which assures that during the starting process the first fuel pump furnishes the fuel to the fuel valves at elevated feed pressure. In many cases, this elevated feed pressure suffices to start the engine in the quickest possible time. The apparatus and the method are intended for an internal combustion engine of a vehicle.

Abstract: A hydraulic valve control apparatus in an embodiment for multi-cylinder internal combustion engine having a reservoir chamber, assigned to a pressure chamber of a valve tappet and having a reservoir piston that serves as a valve, with which the reservoir chamber can be separated from the pressure chamber. The reservoir piston is shifted out of its position of repose to a reservoir function by a hydraulic thrust that is conducted in the reservoir chamber under the control of a magnet valve, via a control line in which a check valve is disposed. Displacement of the reservoir piston occurs only whenever a valve actuation takes place via the drive cam and as a result the working pressure adequate for the displacement of the reservoir piston prevails in the pressure chamber.
