Abstract
An electromagnetically actuated valve ( ) has a core ( ), a solenoid coil ( ) and an armature that can be acted upon by the solenoid coil ( ) in a stroke direction in opposition to a restoring spring ( ), and a valve needle ( ). The valve needle ( ) is fixedly joined both to the armature ( ) as well as to a valve-closure member, which cooperates with a fixed valve seat, and constitutes a movable valve element. On the valve needle ( ), between the armature ( ) and the valve-closure member, an auxiliary body ( ) is arranged, which is movable relative to the valve needle ( ). The valve needle ( ) is designed as having a driving arrangement ( ) such that, in response to a motion of the auxiliary body ( ) in the stroke direction, the valve needle ( ) can be accelerated in the same direction by energy transfer, and a rapid opening of the valve is realized.
