摘要： In a method for operating a valve, e.g., a fuel injector of an internal combustion engine in a motor vehicle which is activated with the aid of an actuator, the actuator is activated using a control variable which has a predetermined control period. The control period is formed as a function of a setpoint value for a closing delay time of the valve which characterizes a time difference between an end of the control period and a closing point in time of the valve.

摘要： A fuel injection apparatus for injecting fuel into the combustion chambers of an internal combustion engine. includes a high pressure accumulator, a pressure booster, and a metering valve. The pressure booster includes a working chamber and a control chamber that are separated from each other by an axially movable piston. A pressure change in the control chamber produces a pressure change in a compression chamber that acts on a nozzle chamber via a fuel inlet. The nozzle chamber encompasses a nozzle needle. A nozzle spring chamber that acts on the injection valve element can be filled on the high-pressure side via a line that leads from the compression chamber and contains an inlet throttle restriction. On the outlet side, the nozzle spring chamber is connected to a chamber of the pressure booster via a line that contains an outlet throttle restriction.
