Abstract

L'invention concerne un premier clapet anti-retour (15) placé dans une première conduite (10) raccordée à une première pompe (11) pour garantir un flux aller de la première pompe (11) jusqu'au circuit hydraulique de moteur principal (5). Une vanne de réglage de pression différentielle (6) est raccordée à une partie amont (10a) située en amont du premier clapet anti-retour (15) de la première conduite (10) et raccordée à une partie aval (10b) située en aval du premier clapet anti-retour (15) de la première conduite (10). La vanne de réglage de pression différentielle (6) décharge de l'huile hydraulique de la partie aval (10b) lorsque la valeur obtenue en retranchant la pression amont (Pa) de la partie amont (10a) de la pression aval (Pb) de la partie aval (10b) est supérieure à une constante (Ps).
