INJECTOR FOR A COMBUSTION ENGINE

摘要

An injector (100) for a combustion engine is disclosed. The injector (100) comprises an injection valve housing with an injection valve cavity, a valve needle (5) being axially movable within the injection valve cavity, an electromagnetic actuator assembly. The electromagnetic actuator assembly comprises a pole piece (1) being fixedly coupled with respect to the injection valve housing in the injection valve cavity and an armature (2) being axially movable within the injection valve cavity for actuating the valve needle (5). The injector (100) further comprises a damping element (7) which is arranged and configured to mechanically interact with the valve needle (5) and the pole piece (1) during movement of the valve needle (5) with respect to the pole piece (1).
