Abstract
Official abstract text for this publication.
A fuel injector, in particular for the direct injection of fuel into the combustion chamber of a mixture-compressing, spark-ignited internal combustion engine, includes a functional part, which has at least one nozzle body, parts of an actuator, an axially movable valve closing body, which forms a sealing seat together with a valve seat surface, as well as a hydraulic extension part, which is fixedly and tightly connected to the functional part. The extension part is an interface between a connection-side inlet stub and the functional part. At least one of the frontal contact surfaces of inlet stub, functional part, and extension part, with which these components press against one another and are fixedly connected, is designed to be convexly curved.
