Magnetic valve for fuel injection system i.e. common-rail injection system, has plate facing surface of magnet core and/or core facing surface of plate including recessed step-like projection in region of residual air gap disk

摘要

The valve has a magnet component (1) provided with an inner pole (2) and an outer pole (3) that forms a magnetic core (4). A magnetic coil (5) comprises a stroke-movable quiescent state component (6) that is provided with an anchor plate (7) and cooperates with the magnet component. A residual air gap disk (8) is arranged between the magnetic core and the plate and consists of a magnetically non-conductive material. The plate facing the surface of the magnet core and/or the core facing the surface of the plate have recessed step-like projection in the region of the residual air gap disk.
