Abstract

Viene indicato un dispositivo elettromagnetico a indotto tuffante, in particolar modo per una valvola elettromagnetica, con una bobina, con un indotto, il quale è disposto all'interno della bobina con possibilità di spostamento in senso assiale, e con un giogo il quale circonda la bobina. Inoltre viene indicato un procedimento per la fabbricazione di un tale dispositivo elettromagnetico. Un tale dispositivo elettromagnetico deve avere una elevata forza di trazione ed un elevato rendimento con una esecuzione compatta. A tale scopo il giogo è formato a una pluralità di tratti circonferenziali di un cilindro (14) con superfici frontali parzialmente cilindriche (16) abbinate a ciascun tratto circonferenziale, di guisa che i tratti circonferenziali racchiudono completamente la bobina e formano gli uni con gli altri degli spazi vuoti in corrispondenza dei loro spigoli longitudinali, e le superfici frontali parzialmente cilindriche (16) racchiudono un percorso magnetico nella zona delle estremità della bobina.Fig. 3
