Abstract

Viene descritta una valvola regolatrice di portata includente un nucleo di materiale ferromagnetico, una molla di richiamo del nucleo, un elettromagnete composto a sua volta da almeno una bobina avvolta su un giogo magnetico, in cui il giogo presenta al proprio interno una cavità nella quale è alloggiato mobile in senso assiale il nucleo, ed un circuito idraulico controllato da un otturatore a spillo portato solidale dal nucleo; questo presenta una forma tale da mantenere sostanzialmente quasi costante la riluttanza magnetica di un circuito magnetico composto dal giogo, dall'elettromagnete e dal nucleo, al variare della posizione assiale relativa tra il nucleo ed il giogo e, in combinazione, la molla è alloggiata in battuta tra uno spallamento assiale della cavità ed una estremità del nucleo ed è atta, in uso, ad esercitare contro il nucleo una forza di richiamo la cui variazione, a seguito di uno spostamento relativo tra giogo e nucleo, è maggiore della variazione della forza di attrazione esercitata sul nucleo dall'elettromagnete in conseguenza dello spostamento.
