ABSTRACT:
This invention relates to an activation apparatus for valves, specifically electromagnetically-activated multiway valves. The activation apparatus exhibits an activation element having a first stop and a second stop, which are arranged in facing-relation to one another, and to a housing projection formed by a graduated opening leading into the valve, so that a movement of the activation element, in the direction of its longitudinal axis, is limited or prevented. On the circumference of the activation element, there is a sealing element which is in sealed contact against the wall of the housing recess or graduated opening, which holds the activation element. The two stops and the sealing element are permanently connected with the activation element so as to form essentially a single-body construction. A valve moving arrangement, formed on the activation member and extending into the valve housing, is movable to an engaged position whereby, operation of the activation member effects manual operation of the valve under emergency or manual conditions.
