Abstract
Dispositif de commande à fluide sous pression comportant une pompe à engrenages de dosage, une pompe à haute pression servant de source hydraulique et un moteur de réglage du mécanisme à commander. Ce dispositif comprend une valve extérieure 6 solidaire par une goupille d'entraînement 8 du pignon intérieur 10 de la pompe à engrenages et une valve intérieure 7 concentrique solidaire de l'arbre menant, ces deux valves pouvant tourner l'une par rapport à l'autre dans une mesure limitée autour d'une position neutre de déviation du fluide sous pression. Application à la commande d'un mécanisme de direction hydrostatique de véhicule automobile.
