Abstract
A magnet valve according to the related art has a sealing and damping device with an elastic region on which, during operation, a force acts due to different existing pressures that must also be overcome when the armature plate is moved. A magnet valve ( ) designed according to the invention has a sealing and damping device ( ) with an elastic region ( ) that is oriented and designed in relation to a seal seat ( ) in such a fashion that the above-described force is offset. As a result, a better characteristic curve of the magnet valve ( ) over the existing differential pressure is obtained.
