ABSTRACT:
In an apparatus for generating pre-injection quantities in unit fuel injectors for Diesel engines, including a pre-injection slide that generates a pronounced pressure intensification for a pre-injection in a pressure chamber closed off with respect to the high-pressure side and opens towards the injection line is slidably supported in a guide bore. The pre-injection slide is exposed to the injection pressure of an element chamber in such a way that after the execution of a partial stroke, which is responsible for the pre-injection quantity, upon further movement the pre-injection pressure chamber is opened toward the element chamber and thereby relieved, and by the ensuing movement of the pre-injection slide until the end of the stroke, a pre-determinable capacity that enables an injection pause is formed. A valve which is supported inside the pre-injection slide is under the control of a magnetic valve associated with the unit fuel injector and provides for the filling of the pre-injection pressure chamber forms selectively actuatable shutoff control for the pre-injection.
