ABSTRACT:
An injector, especially for common rail injection systems of Diesel engines, has a nozzle needle, a control piston for actuating the nozzle needle, a valve that actuates the control piston and that is triggered by via an outlet throttle and an inlet throttle, and a hydraulic stop for the control piston, such that the flow from the inlet throttle to the outlet throttle at the narrowest cross section can additionally be throttled. The control piston is embodied conically on its offset top side oriented toward the outlet throttle or the inlet throttle.
