ELECTROMAGNETICALLY ACTUATED VALVE

摘要

The invention relates to an electromagnetically actuated valve (1), comprising a valve piston (3) bearing a valve plate (2). A spring plate (14) is fastened to the valve piston (3), against which spring plate a valve spring (15) that moves the valve (1) into a closed position lies. The valve also comprises an electromagnet (16), which has a coil (18) and an armature (19) that is arranged on an armature pin (20). The armature pin (20) interacts with the valve piston (3) by means of a contact point. According to the invention, an electromagnetically actuated valve (1) is provided whose function is improved while a low level of structural complexity is attained. This is achieved in that the contact point has a diameter that is enlarged in relation to the diameter of the armature pin (20) and of the valve piston (3) and is planar. Thus, the contact pressure is reduced in this region. Furthermore, by means of a magnetic stray field (29) introduced into the contact point, the closing speed of the valve (1) is increased because of an adherence of the components to each other at the contact point.
