Abstract (en)

[origin: DE10112426A1] The fuel injection valve has a valve element (10) enclosed by a pressure chamber (12), and a spring chamber (25) housing a spring (27) which loads the valve element with a closing force in the direction of the valve seat (16). The pressure chamber and spring chamber are connected by a throttling connection constructed so that the pressure in the spring chamber after termination of the injection cycle up to the beginning of the next cycle falls off at least approximately to the standing pressure.
