Pressure regulating valve for high-pressure storage of fuel injection system, has insert element whose magnetic recess exposes supplementary pole face at front end of core through which anchor plate is expanded with armature surface

摘要

The valve (10) has magnet actuator (20) arranged in valve housing (13). A magnetic core (21) has pole face (26) and armature (22) with anchor plate (27). An armature surface (29) of anchor plate is cooperated with pole face. An insert element (50) is received in terminal-side retainer (45) of housing. A radial outside wall section is supported on magnetic core. A magnetic core-side recess (52) of insert element is provided to expose supplementary pole face (26') at armature side front end of magnetic core through which anchor plate is expanded radially with armature surface.
