Abstract

A solenoid valve with a valve dome in which an armature is contained in an axially movable fashion and onto which a coil is slid for actuating the solenoid valve. In order to mechanically fasten and seal the solenoid valve in a receiving bore of a hydraulic block. A valve seat part is inserted into an open end of the valve dome and an annular ring-shaped valve support is press fitted onto the open end of the valve dome so that the valve seat part, the valve dome, and the valve support are mechanically connected to one another and are sealed in a pressure-tight fashion. The solenoid valve is easy-to-manufacture and is sealed without separate seals.
