INJECTION DEVICE COMPRISING AN ACTUATOR FOR CONTROLLING THE NEEDLE STROKE

The injector device has an injector with a pressure chamber (1), from which a high pressure line (3) opens into a control chamber (4) of a nozzle needle (5). The injector also contains two control valves (11,12), which are connected to low pressure areas (9) on the discharge side. One of the control...

Zusammenfassung:The injector device has an injector with a pressure chamber (1), from which a high pressure line (3) opens into a control chamber (4) of a nozzle needle (5). The injector also contains two control valves (11,12), which are connected to low pressure areas (9) on the discharge side. One of the control valves that determine the injection pressure response contains a pressure compensation system, which enables the injection pressure response to be varied by modifying the stroke path of the nozzle needle.
