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.

Activation apparatus for operating, under emergency and manual conditions, an electromagnetically-controlled multiway valve, having at least one inlet and one outlet port, and at least one valve arrangement disposed therebetween, and all formed in a valve housing, said activation apparatus comprisin
Activation apparatus for operating, under emergency and manual conditions, an electromagnetically-controlled multiway valve, having at least one inlet and one outlet port, and at least one valve arrangement disposed therebetween, and all formed in a valve housing, said activation apparatus comprising: (a) an activation member disposed in a housing recess formed in the valve housing, said activation member extending at least partially into a pressure chamber in which the at least one valve arrangement is disposed; (b) sealing means connected to said activation member for sealing said activation member against said housing recess; (c) holding means partially formed in said housing recess, and interacting with said activation member for holding said activation member in an engageable position with said housing recess, said holding means including first and second stop surfaces formed on said activation member, which interact with at least one complementary stop surface, formed in said housing recess, so as to limit movement of said activation member in the direction of the longitudinal axis of said housing recess; (d) at least one of said first and second stop surfaces formed on said activation member being elastically-deformable such that, upon introduction of said activation element into said housing recess, said activation member can be guided past said complementary stop surface and, once past said complementary stop surface, said elastically-deformable at least one stop surface can resume its original shape and interact with said complementary stop surface in the manner of a snap-connection; (e) said first and second stop surfaces and said sealing means being permanently affixed to said activation member to form essentially a single-piece component; and (f) valve moving means formed on a portion of said activation member, extending into said pressure chamber, for moving a valve body portion of the at least one valve arrangement when the electromagnetically-controlled multiway valve is operating under such emergency and manual conditions.
