摘要： The present invention relates to an injector for injecting fuel, comprising an injector housing, a movable nozzle needle which is arranged in the injector housing and has a nozzle needle tip, a nozzle needle seat for receiving the nozzle needle tip, and a mechanical switch which upon contact of the nozzle needle tip with the nozzle needle seat assumes a closed state and upon interruption of the contact assumes an open state, wherein the injector is provided with an input line and an output line for actuating a movement of the nozzle needle, and the switch includes a first terminal and a second terminal. The injector is characterized in that the first terminal of the switch is connected to the input line and the second terminal of the switch is connected to the injector housing.

摘要： An injector for injecting fuel including an injector housing, a movable nozzle needle with a nozzle needle tip arranged in the injector housing, and a nozzle needle seat for receiving the nozzle needle tip. A contact pairing of the nozzle needle and the nozzle needle seat here represents a mechanical switch that adopts a closed state upon contact of the nozzle needle tip with the nozzle needle seat and an open state upon interruption of the contact. Provision is additionally made that the injector has an input line and an output line for controlling movement of the nozzle needle, the switch has a first connector connected to the input line and a second connector connected to the injector housing, and a resistor connected between the first connector of the switch and the input line.

摘要： The invention relates to a fuel injection valve for the intermittent injection of fuel into the combustion chamber of an internal combustion engine having a housing which has a high pressure chamber and a low pressure chamber. In addition, the fuel injection valve has a control chamber which is divided by means of a control valve into a first and a second control chamber. The control valve in turn has a valve guide and a valve insert, wherein an outflow throttle which connects the first control chamber to the second control chamber is arranged in the valve guide. According to the invention, the connection which is formed by way of the outflow throttle between the first control chamber and the second control chamber can be interrupted temporarily in a targeted manner.
