Electromagnetic operating arrangement for intake and exhaust valves of internal combustion engines

An electromagnetic operating arrangement for actuating intake and exhaust valves of internal combustion engines, each valve having a valve stem with a valve closing spring engaging said valve stem for biasing said valve into a valve closing position, a valve operating member movably supported in axial alignment with said valve stem, an operating member spring engaging said valve operating member so as to bias it into engagement with said valve stem, an armature disc supported on said valve operating member, control magnets arranged in spaced relationship at opposite sides of said armature disc for holding said armature disc in an open valve or closed valve position respectively, said armature disc being movably supported on said valve operating member and said valve operating member having a first stop adjacent said armature disc and a spring arrangement for forcing said armature disc toward said stop and into engagement with said valve operating member, said operating member spring exerting a spring force when said valve is in the closed position and said armature disc is in engagement with the respective control magnet which is greater than the spring force exerted by said spring arrangement wherein said valve operating member always remains in force-transmitting contact with said valve.
