Abstract

Un attuatore rotativo, programmabile, comprendente un circuito oleodinamico, autobilanciato, di regolazione della velocità di rotazione dell'albero d'uscita. Una prima cremagliera di spinta è azionata da pistoni mobili alternativamente in camere selettivamente collegabili ad una sorgente di un primo fluido in pressione; una cremagliera di controllo della rotazione dell'albero è a sua volta provvista di pistoni mobili in camere separate, collegate ad un circuito chiuso di circolazione per un fluido idraulico in pressione. Il circuito comprende mezzi a valvola di regolazione della circolazione del fluido collegati ad un organo pneumatico di controllo, programmabile per variare la velocità di rotazione dell'attuatore.
