摘要： A valve for controlling fluids that are at high pressure has a valve seat region at which a high-pressure region and a low-pressure region can be made to communicate with one another or can be disconnected from one another. A seat face for a conical valve member is embodied on a valve body, and the seat face extends in inclined fashion in the valve body. The conical valve member has a multiconical geometry in the valve seat region, with at least one first conical face and one second conical face, which have different cone angles from one another.

摘要： The valve has a valve member (72) that is guided so that it is able to slide in the direction of its longitudinal axis (73), protrudes into a valve pressure chamber (77) and, in the valve pressure chamber (77), has a sealing surface (81) at an end extending transversely in relation to its longitudinal axis (73), with which sealing surface (81) the valve member (72) cooperates with a valve seat (79) extending transversely in relation to its longitudinal axis (73) in order, at least to a large extent, to close an opening (78) encompassed by the valve seat (79) in relation to the valve pressure chamber (77). The opening (78) is adjoined by a connection (64) leading to a low-pressure region. The valve member (72) has a pin (83) that protrudes into the connection (64) and, when the sealing surface (81) of the valve member (72) is lifted away from the valve seat (79), this pin (83) conveys fluid flowing out of the valve pressure chamber (77) in such a way that the outgoing fluid exerts at least approximately no resulting force on the valve member (72) in the direction of its longitudinal axis (73).

摘要： The fuel injection device has a fuel pump, which has a pump piston that is driven by an engine and delimits a pump working chamber, which is supplied with fuel from a fuel tank and is connected to a fuel injection valve, which has an injection valve member that controls at least one injection opening and can be moved by the pressure generated in the pump working chamber in an opening direction counter to a closing force. A first control valve controls a connection of the pump working chamber to a discharge chamber, and a second control valve controls the pressure prevailing in a control pressure chamber of the fuel injection valve. The connection of the pump working chamber further contains a pressure-holding valve, which maintains a pressure that is higher than the pressure prevailing in the discharge chamber.

摘要： A fuel injection system for internal combustion engines essentially has a high-pressure injection pump, supplied with fuel from a low-pressure region, and a magnetic piston valve serving to control the injection pump. The magnetic valve having two coaxial valve chambers, communicating with one another through a valve opening but separable from one another by a valve seat, and an armature chamber. The armature chamber communicates with the inlet side via a pressure conduit, and the low-pressure valve chamber communicates with the outlet region of the injection pump. The low-pressure valve chamber has a fuel inlet conduit and a fuel outlet conduit, both of which have a gradually tapered cross section compared to the cross section of the remaining regions of the fuel inlet conduit and fuel outlet conduit. Maximal prevention of cavitation is successfully achieved in the region of the low-pressure valve chamber and hence cavitation erosion that is possible as a consequence of cavitation.

摘要： A fuel injection device for internal combustion engines, having a high-pressure fuel pump, which pumps fuel from a low-pressure chamber via a feed line into a high-pressure collection chamber that communicates via high-pressure lines with the individual injection valves that protrude into the combustion chamber of the engine to be supplied. In order for this system to make variable injection cross sections at the injection valves possible, these injection valves are embodied as injection valves with an outward-opening valve member, via whose controllable opening stroke motion in the direction of the combustion chamber, a variable injection cross section can be adjusted at the injection valve.

摘要： In a fuel injection pump of the distributor type, a solenoid valve is provided in the distributor and the valve member of this solenoid valve is supported in an axial bore of the distributor and actuated by a magnet fixed to the housing in order to block the connection between a pump working space of the distributor-type injection pump and a relief space during an intended high-pressure injection phase. Inherent in its construction, a distributor of such a fuel injection pump has a certain axial play in its mounting and this has an effect on the actuating travel of the valve member in the distributor in relation to the fixed electromagnet. In order to avoid changes in the magnetic properties, which can arise due to this axial association, part of the magnetic circuit in the form of a magnet plate is displaceable together with the distributor, with the result that the position of an armature connected firmly to the valve member relative to this part of the magnet core, with which it forms the working air gap, does not change depending on the axial position of the distributor, and the magnetic properties of the solenoid valve are thus maintained irrespective of the axial position of the distributor.

摘要： A process for controlling and measuring the movement of an armature of an electromagnetic switching member with an excitation coil is proposed, which has the following steps: a current (i) or a voltage (u1) is applied to the excitation winding (3) in order to move the armature into a first actuatable position; before the start of the movement of the armature, the current or the voltage is raised above a value at which the armature remains in the actuated position, and before termination of the movement of the armature the current or the voltage is reduced to a defined value, which suffices to hold the armature in the actuated position; finally, the temporal variations in the current or the voltage are measured after setting of the defined value, for the purpose of recognizing the termination of the armature movement. With the aid of this process, it is possible for the movement of the armature, for example of a solenoid valve for a fuel injection device of an internal combustion engine, to be very precisely monitored, so that the injection instant and injection period can be optimally set.

摘要： A method for operating a fuel injection system of an internal combustion engine is described. The fuel injection system has an injector for metering fuel into a combustion chamber of the internal combustion engine. The injector has an actuator, a control valve and a nozzle needle. In the method, the actuator is supplied a voltage and/or a current during an activation period. The control valve is set into a lifting motion by the actuator. The injector is opened and closed by the nozzle needle, using the lifting motion of the control valve. A further time period is ascertained. The further time period ends at the closing time of the nozzle needle. A function is ascertained, which links the activation period to the further time period. A shortest activation period, for which the nozzle needle opens and produces an injection, is ascertained with the aid of the function. An opening delay period (do1) of the nozzle needle is ascertained as a function of the shortest time period.
