Abstract

Cette servo-direction comprend une pompe d'alimentation 11, mue par le moteur à combustion interne 10 d'un tracteur agricole par exemple, un vérin de direction 44 et une pompe à main 36 commandée par le volant 35. Pendant la direction manuelle assistée, le vérin 44 est alimenté à travers le distributeur de direction 24 à commande manuelle, couplé mécaniquement au volant, et une valve de commutation 27. Pendant la direction automatique du véhicule, l'alimentation du vérin s'effectue à travers un distributeur de direction 17 à commande électromagnétique et la valve 27, mais une intervention manuelle sur le volant est possible Une telle intervention produit la commutation de la valve 27 et la liaison directe des sorties 25, 26 du distributeur 24 au vérin 44 et aux deux sorties 38, 39 du distributeur 17.
