Abstract

Object: Device comprising an electromagnet (1) and an actuating element (2) which is operated by said electromagnet and may be, for example, a valve or a clutch, wherein said components are connected to one another by means of threads (4) and (5), with protection of functional spaces in the components or of elastomeric seals against damage and adverse effects on functioning by particles from the threads.Solution: The electromagnet-side thread (4) and actuating element-side thread (5) are axially adjacent in both directions of chambers (6) and (7) which are closed off on in each case the side which is averted from the threads by overlapping cylinder surfaces (11) and (12) on one side and also by further overlapping cylinder surfaces (13) and (14) on the other side.Application: Actuating elements which are operated by an electromagnet.
