Arrangement for forming magnetic valve for operating fuel injector, has anchor whose upper surface facing toward anchor abutment surface includes groove with defined groove width and depth in over-covering area with anchor abutment surface

摘要

The arrangement has magnet components and a stroke movable anchor (3) for formation of a magnetic valve. The magnet components include a magnetic core (1) and a magnetic coil (2), and a residual air gap disk is arranged between the magnetic core and anchor for formation of an anchor abutment surface (5). An upper surface (6) of the anchor facing toward the abutment surface includes a groove with defined groove width and defined groove depth in an over-covering area (7) with the abutment surface. The groove is arranged in reference to a longitudinal axis of the anchor.
