Electromagnetically-controlled multi-jet fuel injection valve

摘要

The fuel injection valve is used for an IC engine with at least 2 air intake channels for each cylinder and has a jet body (9) with a corresponding number of injection channels (10,11), controlled via a valve device (100) operated via an electromagnet (2). The central valve needle (7) has a 2-part seal, with a central seal spring-biased against the valve seat and a second seal (110) provided by a ball (111), spring-biased radially into contact with a radial seat in the jet body.
