Abstract
A common rail injector having an injector housing that can be made to communicate via a high-pressure connection with a high-pressure reservoir. A nozzle needle is axially displaceable against a nozzle needle seat in order to adjust the injection onset and the injection quantity in a common rail injection system of an internal combustion engine as a function of the position of a magnet-controlled control piston that is prestressed counter to a spring. To make it possible that during operation to characterize the opening and closing operation of the nozzle needle, the nozzle needle is coupled via an intermediate piece to a servo piston that cooperates with the control piston.
