Abstract

The invention relates to an electromagnetic valve for an injector for a common rail fuel injection system, comprising a valve control system for opening and closing a nozzle. The aim of the invention is to compensate for pressure drops inside the injector (1), for example, caused by air inclusion in the fuel to be injected. To this end, a damping element (15) is arranged between the electromagnetic valve (8) and the electromagnetic valve armature (9), above-mentioned damping element exerting a damping force on the electromagnetic valve armature (9) and thus on the nozzle needle (5).
