ABSTRACT:
An electromagnetic valve is provided with an elongated tappet guided axially displaceably in a tappet guide, and with a sealing body, embodied on the tappet, that can seal against a sealing seat. So that the valve can be produced more economically yet can be regulated more precisely, the sealing seat and the tappet guide are embodied in one piece. The adjustability of the valve is assured in particular by an adjusting ring.
