Abstract
Un sistema idraulico di sterzatura per veicoli presenta una unità di sterzatura (1) per il funzionamento di un motore dello sterzo (14). In via alternativa il motore dello sterzo (14) può venire alimentato con liquido in pressione per mezzo di una valvola di derivazione (16). Ciascun vano (12, 13) del motore è collegato per mezzo di una valvola di commutazione (10, 11) alternativamente con il prodotto (20, 21) del motore della valvola di derivazione (16) oppure con un condotto (8, 9) del motore della unità di sterzatura (1). La valvola di commutazione (10, 11) può venire azionata in relazione alla messa in funzione della unità di sterzatura (1).In questo modo il motore dello sterzo si può regolare più rapidamente rispetto al caso della unità di sterzatura, senza che vada perduta la sicurezza di sterzatura durante il normale funzionamento in sterzata.
