Abstract
The invention relates to a directly controlled magnetic valve, comprising a fixed core which is located in a magnet and a moving armature to which a seal plate is fixed by means of a tappet. When the valve is activated, the seal plate interacts with a valve seat which is fixed to the housing. Corresponding sealing elements are provided on the seal plate and on the valve seat and at least the tappet and the seal plate have bores which are situated centrally in the longitudinal direction. The aim of the invention is to produce a magnetic valve which has a large nominal width allowing a small construction volume, a low power requirement, rapid pressure compensation and rapid switching. To this end, second sealing elements which correspond with each other are provided on a front face which is permanently connected to the armature and on an adjacent face which is fixed to the housing. Like the first sealing elements, these second sealing elements are situated at least approximately coaxially to the geometrical longitudinal axis. The second sealing elements delimit at least approximately the same pressure surface as the first sealing elements. The first and second sealing elements are ef…
