Abstract
A fuel injector for fuel injection systems of internal combustion engines, which is composed of two preassembled, independent subassemblies. In this context, a functional part essentially includes an electromagnetic circuit and a sealing valve, whereas a connecting part is essentially constituted of a hydraulic connection. In the ready-assembled injector, electrical connecting elements and hydraulic connecting elements of both subassemblies cooperate so that a reliable electrical and hydraulic connection is ensured. The valve is executed as a side-feed injector, and the electrical connection is located farther away from functional part than the hydraulic connection of the connecting part. The fuel injector is particularly suitable for use in fuel injection systems of mixture-compressing, positive ignition internal combustion engines.
