Abstract

On the housing side, a high-pressure injector (1) has a central receptacle chamber (16) which lies between the actuator and the control valve (17) and is penetrated centrally by a control rod (23) which is multiple times as long as it is thick, and which receptacle chamber (16) forms, at least over part of its length, a pressure accumulator (24), in which the control rod (23) is surrounded directly by the fuel.
