ABSTRACT:
A pressure regulating valve for regulating the pressure in a common rail, having a pistonlike valve member which is axially displaceably guided in a bore and acts on a closing element that can be pressed against a valve seat, and the valve member forms an armature of an electromagnet, to which current can be supplied. The minimal spacing between the armature and the valve housing is adjustable. In this way, the setting of the closing force of the valve can be done in the preassembled state.
