Abstract: In fuel supply systems with two fuel pumps connected in series and fuel valves that inject directly into the combustion chamber, there have been occasional problems. The proposal is made that in order to eliminate these problems, the first fuel pump operates with increased delivery capacity, particularly during the startup process and in the event of high fuel temperature. The fuel supply system is provided for an internal combustion engine of a vehicle.

Abstract: An injection system for internal combustion engines is proposed, in which once the engine has been turned off, a pressure equalization is established between the intake side and the pressure side of the high-pressure fuel pump. This prevents uncombusted fuel from reaching the combustion chambers of the engine. The pressure prevailing on the pressure side and the intake side when the engine is off furthermore assures that vapor bubbles cannot form, and this makes starting the engine easier.

Abstract: A pressure control valve serves to regulate the fuel pressure in a fuel system. The pressure control valve includes a valve housing, at least one inlet, at least one outlet, and at least one prestressed, electrically actuatable, and at least regionally ball-shaped valve member. The valve member cooperates with a valve seat structurally connected to the housing. To make it possible to achieve stable closed- and/or open-loop control properties of the pressure control valve, it is proposed that the valve seat widen conically toward the valve member, and the ball diameter of the valve member is selected such that with the valve closed, the valve member touches the valve seat in the vicinity of its farther end.

Abstract: A fuel injection system for internal combustion engines, having a high-pressure fuel pump which fills a high-pressure collection chamber with high fuel pressure. Injection lines lead away from the high pressure collection chamber to the individual injection valves. A prefeed pump that feeds fuel from a tank via a low-pressure line system into a work chamber of the high-pressure pump, and at least one control valve controls the high-pressure pumping quantity of the high-pressure pump.

Abstract: The hydraulic setting device has a differential cylinder (11) whose annular space (14) is continually subjected to pressure by a pump (16). The pressure space (18) at the large piston surface is connected to the pump via a connection conduit (41). A conduit branch, which leads to a control valve (21), emerges from this connection conduit (41). At the other end, this control valve is in connection with a return conduit (26). The pressure in the conduit branch (19), and therefore in the pressure spaces (14, 18) of the differential cylinder, can be varied by appropriate activation of the control valve.

Abstract: A fuel injection pump of a distributor type for internal combustion engines including, a pump plunger guided within a pump cylinder, which forms a pump chamber and which is driven to perform reciprocating and rotating motion by a driving gear which is submerged in a lubricating oil bath. The pump plunger has a distribution hole which is in contact with the pump chamber and which sequentially links this chamber, during the compression stroke of the pump plunger, to injection jets. The fuel filling of the pump chamber takes place via a magnetically operated valve, which is open during the intake stroke and closed during the compression stroke of the pump plunger. For an enlargement of the filling cross-section during the intake stroke without an enlargement of the opening of the magnetically operated valve, a relief hole in the pump plunger is used which serves a force balancing during the compression stroke and which during the intake stroke links up with a filling hole which is connected with a membrane reservoir.
