<p>A jet needle has a front face turned away from an injection opening. An injector assembly has a chamber within the body adjoining the front face, a throttle module arranged in the chamber having a fluid supply chamber being hydraulically coupled to the fluid inlet, a control space hydraulically coupled to the fluid supply chamber via an inlet throttle, and a valve chamber hydraulically coupled to the control space via an outlet throttle for accommodating a valve that is designed to lead fluid into a fluid return line arranged in a control module. There are precisely two sealing edges designed between the throttle module and the injector body and/or the control module by which additional hydraulic couplings of the fluid supply chamber to the control space and the valve chamber are cut off. A third sealing edge is designed between the injector body and the control module.</p> |
