Devices operated by electromagnets and having encapsulated threaded connections

Abstract

The invention relates to a device consisting of an electromagnet (1) and an adjusting mechanism (2) operated by said electromagnet, which can be, for example, a valve or a clutch, wherein said part is passed through a thread ( 4) and (5) are connected to each other with a guard for preventing the functional space or the elastic seal of said part from being damaged by particles from the threads or affecting the function. Solution: The thread (4) on the electromagnet side and the thread (5) on the adjustment mechanism side are axially adjacent in both directions of the cavities (6) and (7) which on the one hand pass through overlapping cylindrical surfaces (11) and (12) and on the other hand are each closed on the side facing away from the thread by a further pair of overlapping cylindrical surfaces (13) and (14). Application: Adjustment mechanisms operated by electromagnets.

Description

technical field [0001] The invention relates to a device operated by electromagnets according to the general concept of the first claim. Background technique [0002] Electromagnets for operating clutches, valves or other adjusting mechanisms have been known and widely used for many years. [0003] Among them, there are generally two structural forms in terms of the interface between the electromagnet and the adjustment mechanism. In the first configuration, the two parts are connected inseparably because they contain a common part or common parts. A common part is in most cases the poles of the electromagnets. [0004] In the second embodiment, the parts are inserted and / or are fixed to one another by caulking gaps or by screwing. [0005] Screwed connections offer many advantages, but also have the disadvantage that particles can escape from the thread during the screwed connection, which particles can enter the functional cavities of the components and cause a function...

AI Technical Summary

Problems solved by technology

[0005] Bolted connections offer many advantages, but also have the disadvantage that during the bolted connection particles can be released from the thread, which particles can enter the functional cavities of the component and cause a functional impairment there

If there is a seal adjacent to the thread, particles can functionally interfere with the seal or even damage the seal
