Abstract: For controlling high-pressure phases during the stroke of a pump piston of a fuel injection pump, magnetic valves are also used, which are built into relief lines of the pump work chamber of such fuel injection pumps and which with the instant of closure of the relief line determine the injection onset and with the instant of reopening of the relief line determine the end of injection and hence the injection quantity. Such valves must be capable of switching rapidly, in view of the high rpm of internal combustion engines, yet must be as small as possible and use the least possible energy. By using a piston slide which in the closing state is balanced in pressure on the high-pressure side, and by relieving the chambers defined on the face end by the piston slide, a fast-switching, recoilless magnetic valve is obtained, which is opened by a restoring spring when the electromagnet is in the currentless state. This makes the use of the magentic valve in combination with electrically controlled injection pumps particularly advantageous.

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 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.

Abstract: A fuel injection pump for internal combustion engines has a pump piston, defining a pump work chamber for generating an injection pressure; an electromagnetic control device for fixing the duration of supply during the supply stroke of the pump piston and a measuring device, which measures the return flow fuel quantity that did not attain injection during the supply stroke of the pump piston and emits an electronic return flow quantity signal (Q.sub.R). An electronic control unit imposes control signals (.phi..sub..mu.V) upon the control device as a function of the return flow quantity signal (Q.sub.R) and operating characteristics of the engine. To attain highly accurate closed-loop control of the fuel injection quantity, a fluctuation detector is provided, which detects fluctuations in the return flow quantity signal and emits the appearance of fluctuations over time in the form of detection signals (.phi..sub.A, .phi..sub.E, .phi..sub.1 -.phi..sub.4). The control unit corrects the imposition of the control signals (.phi..sub..mu.V) as a based on these detection signals.
