Abstract:
An injector for a combustion engine may include a valve housing, a valve needle, an electromagnetic actuator, and a damping element. The valve needle may be axially movable within a valve cavity of the housing. The electromagnetic actuator may comprise a pole piece coupled with the valve housing and an armature axially movable within the valve cavity. The pole piece may have a central recess extending axially there through. The central recess may include a step defining a first portion and a second portion, the first having a larger cross-sectional area than the second, and a stop surface defined by a radially extending surface of the step. The valve needle may include an armature retainer in the first portion of the central recess. The armature may be axially displaceable with respect to the valve needle and interact with the valve needle by means of the retainer for actuating the valve needle. The damping element may be arranged between the stop surface and the armature retainer to interact with the valve needle and the pole piece during movement.
