Actuating element with permanent magnet e.g. for actuating gas-exchange valves in combustion engine, has permanent magnet mounted in sleeve made from non-magnetic material with collar at one end for supporting spring-plate

摘要

Actuating devices require the position and/or movement of individual actuating elements to be accurately detected and thus require a mechanically stable connection to the permanent magnet, so as to prevent the magnet loosening etc during operation. The permanent magnet (13) is located in a sleeve (14) made of a non-magnetic material and has floor or base (16) at one end and a collar or flange (15) at the other end, on which is supported a spring-plate (11).
