Disc valve turning device for I.C. engines during the valve closing movement using roller or slide elements which are loaded in pockets with inclined planes arranged concentric around the axis of a base element compressing springs in the direction of the flatter pocket sides and acting together with a spring element which is tensioned in the direction of the valve axis as in 19 55 820. the spring element (1) consists of several disc springs located behind each other so that in the event of a load not exceeding the carrying capacity of a single spring a spring movement multiplied against the single spring movement can be attained which also corresponds to the number of disc springs used. |
