MAGNETIC CLUTCH

摘要

A magnetic coupling for translatorily movable bodies that is made in one position, is arranged so that it can be broken, without external control, in another position. For this purpose the first body has a coupling element of permanently magnetic or magnetizable material, the second body has at least one complementary coupling element of permanently magnetic or magnetizable material, and a third body has a coupling element of permanently magnetic or magnetizable material cooperating with the second body. Arranged between the complementary coupling element of the second body and the coupling element of the third body that is a spacer which can be moved as desired between the working positions.
