Abstract

Circuit de transmission de fluide vers un moteur actionné par ce fluide Le moteur est actionné par au moins trois pompes fonctionnant en parallèle, à la sortie d'au moins deux pompes on interpose une vanne qui peut relier la sortie d'une pompe au moteur à fluide ou à un réservoir de stockage. Un detecteur de pression du fluide commande cette vanne. En cas d'accroissement de la pression, les vannes sont successivement placées dans la position qui correspond à la liaison entre une pompe et le réservoir de stockage. Application au circuit de commande de moteur hydraulique pour véhicules de chantier.
