摘要： The invention relates to a device for actuating a control piston or nozzle needle (27) via a control chamber (26). The control chamber communicates via a control chamber line (25) with valve chambers (3, 22) of a 3/2-way valve (5). The valve body (6, 40, 51) of this valve is switchable by means of an actuator (11). By means of a restoring spring (14), the valve body (6, 40, 51) is acted upon such that a seat portion (7), embodied in the housing (4) on the valve body (6, 40, 51), is put into its valve seat (20). The valve body (6, 40, 51) of the 3/2-way valve (5) has a seat portion (7) and a longitudinal slide portion (8), as well as hydraulic faces (31,32), facing one another, that make the state of pressure equilibrium of the valve body (6, 40, 51) possible. The valve body (6, 40, 51) is moved to different stroke lengths (10; 23, 24) by means of an actuator (11).

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 valve control unit for a fuel injection valve, has a housing body, in which two valve control chambers that communicate continuously with one another are provided. The first valve control chamber communicates fuel with an inflow conduit for fuel pressure on a terminal member of a valve control piston which is displaceable in the housing body and the second valve control chamber communicates with a closable outlet conduit. A mechanical stop for limiting the mobility of the valve control piston in the direction of the second valve control chamber is embodied on the housing body. The quantity of preinjected fuel can be minimized by the volume of fuel in the first valve control chamber.

摘要： A valve for controlling fluids, which is provided with a fluid-filled coupling chamber that is disposed between an actuator piston of a piezoelectric actuator and a piston that actuates a valve member. In order to compensate for a leakage in the coupling chamber that is intermittently under high pressure during a switching procedure, a filling valve is provided that is disposed radially on the coupling chamber, but outside the chamber, and this valve monitors an inflow from an inlet conduit that is under ambient pressure in the valve. In this manner, on the one hand, the clearance volume produced by the attachment of the filling valve is very small and on the other hand, the filling valve is independent of the accelerated movements of the pistons, i.e., independent of their acceleration forces. The valve is designated for use in fuel injection devices for internal combustion engines of motor vehicles.

摘要： The fuel injection apparatus has one fuel pump for each cylinder of the engine, which pump has a pump piston, driven by the engine in a reciprocating motion, that defines a pump work chamber, which communicates via a line with a fuel injection valve, disposed on the engine separately from the fuel pump, which valve has an injection valve member, by which at least one injection opening is controlled, and which is movable in the opening direction, counter to a closing force, by the pressure generated in the pump work chamber, and at least one first electrically triggered control valve is provided, by which a communication of the pump work chamber with a relief chamber is controlled, and which is disposed near the fuel pump. A second electrically triggered control valve is provided, which is disposed near the fuel injection valve and by which the pressure prevailing in a control pressure chamber of the fuel injection valve is controlled, by which pressure the injection valve member is urged at least indirectly in the closing direction.

摘要： The invention relates to an arrangement for injecting fuel, which is at high pressure, into an internal combustion engine. An injector (25) encloses a pressure chamber (1), from which a high-pressure line (3) discharges into a control chamber (4) of a nozzle needle (5). Also contained in the injector (25) are two control valves (11, 12), which on the outlet side communicate with regions (9) of a lesser pressure level. One of the control valves (11, 12) that form the injection course (20) contains a pressure compensation system (34), by which the injection pressure course (20) can be varied by varying the stroke length (23) of the nozzle needle (5).
