Abstract (en)
[origin: WO03046369A1] The invention relates to an injector for high pressure injection of fuel in auto-igniting internal combustion engines. The injector comprises an actuator valve for opening and closing the injector, an injector needle (17) which seals at least one injection opening (18) when the injector is in a closed state, a metering valve (4) producing a hydraulic connection between the actuator valve and the discharge area (6) of the injector, a pressure maintenance device (33) which is used to maintain the pressure required for the metering valve (4), a first line (20) for control amounts (34) flowing via the actuator valve and a second line (43) for control amounts flowing via the metering valve (4). The pressure maintenance device (33) dynamically separates the control amounts (35) from the metering valve from the control amounts (34) from the actuator valve by means of a hydraulic vibration damper.
