Abstract
The invention relates to a fuel injector comprising an actuator modulearranged in a holding body, wherein the holding bodyis braced by means of a tension nutto a nozzle bodyby means of at least one interposed intermediate body designed as a throttle plate, wherein the throttle plateis penetrated by at least one high pressure channel, an inflow channelhaving an inflow throttle, and an outflow channelhaving an outflow throttle, and wherein a valve actuated by the actuator module, said valve having at least one valve pinand a sealing sleeve, is arranged between the actuator moduleand the throttle plate, forming a leakage chamberfacing the throttle plate. According to the invention, a fuel injector is provided, wherein the leakage discharge out of the leakage chamberis ensured without impairing the tightness of the fuel injector in the areas adjacent to the throttle plate. This is achieved in that a horizontal leakage outlet channel, which extends from the cylindrical outer circumference of the throttle plateto a region underneath the leakage chamberand is hydraulically connected to the leakage chamberby way of a leakage channel, is recessed in the throttle plate
