Abstract

Il trovato si inserisce nel campo dei regolatori di coppia ed in particolare dei limitatori di coppia per attuatori gasidraulici che presiedono al comando di valvole/.Più precisamente si riferisce ad un dispositivo limitatore di coppia che limita la cappia di sollecitazione di una valvola mandando in scarico il gas qualora la differenza di pressione tra il gas contenuto in una camera (11) e l'olio di una camera (9) superi un certo valore prefissato impostato mediante la taratura di una molla (6).Il dispositivo è utilmente applicato per impedire rotture e danneggiamenti alle valvole in caso di sollecitazioni di intensità troppo elevata conseguenti a situazioni di blocco delle valvole stesse.
