Abstract

See full text

An injector having a valve opening, a cylindrical pipe, a valve opening, a valve needle situated inside the pipe in the radial direction and guided to allow axial displacement; a solenoid coil situated outside the pipe in the radial direction; a solenoid core disposed inside the pipe in the radial direction; and a magnetic armature situated inside the pipe, opposite the solenoid core in the radial direction, the magnetic armature being disposed on the valve needle. The pipe is a magnetic first material in a first pipe region and a third pipe region, the first region facing the valve opening in the axial direction, and the third pipe region facing away from the valve opening in the axial direction. The pipe is a non-magnetic second material in a second pipe region, the second pipe region being between the first pipe region and the third pipe region in the axial direction.
