摘要： A nozzle needle (60) of a fuel injection valve is guided axially in a nozzle body (50), and it points with its rear end face (61) into a compression chamber (15) and is operatively connected to a damping body (40). The recesses (46, 47, 48) of the damping body (40), together with the damping bore (14), form a fuel-filled damping chamber (40). Upon valve opening, the fuel in the compression chamber is compressed, and thus the valve opening is delayed. If the nozzle needle exceeds the damping stroke (hd), then the fuel is depressurized by a communication with an outflow chamber (12). The damping body is guided over at least part of its length in the damping bore.

摘要： A control valve for a fuel injector, especially of an air-compressing, spontaneous-ignition, internal combustion engine. The control valve includes a valve body in the form of a piston valve which is axially movable in a housing chamber into a closure position and an open position, with the closure position being determined by a valve seat on the housing, and a seating surface edge on the piston valve. The housing chamber includes at least one high pressure connection, and a low pressure connection. The basic problem with a control valve of this general type is that when the piston valve strikes the valve seat, rebound movements are carried out by the piston valve, so that the closure position can only be reliably assumed after a certain time delay, thus negatively influencing the injection process. In order to avoid these drawbacks, it is possible to have the valve housing chamber, either between its valve seat and the high pressure connection on the one hand, as well as the high-pressure side of the piston valve adjacent the seating surface edge on the other hand, or between its valve seat and the low pressure connection on the one hand as well as the low-pressure side of the piston valve adjacent the seating surface edge, each being provided with a portion having the same diameter. Alternatively, an attenuation mass, especially an attenuation piston element, can be provided on and/or within the piston valve, with this attenuation mass being movable relative to the piston valve.

摘要： The regulating member according to the present invention is arranged in a pressure line in a fuel injector with a pressure intensifier and has an actuator, a valve chamber and a spring-loaded valve piston arranged moveably in the valve chamber. The valve piston, in its position of rest, makes a flow connection through the valve chamber between a pressure supply and a control space of the pressure intensifier and, in its switching position, the valve piston makes a flow connection through the valve chamber in which the control space in the pressure intensifier is relieved of pressure.

摘要： A configuration for amplifying fuel pressure for a fuel injector includes a pressure amplifier having a control space on a low-pressure side, a working space on a high-pressure side, and a moveable ram disposed between the control and working spaces. The control space is connected to an accumulator through a pressure line, and the working space is connected to a fuel line. The device includes an actuator connected to a servovalve for changing between an actuated switched state and an unactuated initial state. In the pressure line is the servovalve between the pressure supply and the control space, which opens the pressure line in the unactuated initial state, and interrupts the pressure line and keeps unpressurized the control space in the actuated switched state. A method for amplifying the fuel pressure includes: connecting the pressure supply to the pressure amplifier, and to the control space through the pressure line; connecting the working space to an injection nozzle with the fuel line; placing the servovalve in the pressure line between the pressure supply and the control space; connecting the actuator to the servovalve; opening the pressure line with the servovalve when the actuator is unactuated; and interrupting the pressure line and keeping unpressurized the control space with the servovalve upon actuation.

摘要： The apparatus and method of regulating a control valve for a Diesel injection system comprises a fuel injector having a pressure amplifier preceded by the control valve (10), the slide (20) of the control valve (10) being moved by two spatially separated magnet coils (30, 32). During an electrical triggering of one of the two magnet coils (30, 32) with a control current, the respective other magnet coil (32, 30) is switched as a sensor, detecting the current induced in the sensor by a motion of the valve slide (20).
