Abstract

Direction assistée comprenant une pompe manuelle commandée par le volant et constituant un dispositif doseur, une pompe à huile haute pression commandée par le moteur et un distributeur de commande mobile dans les deux sens en fonction de la rotation du volant et monté entre des canaux menant de la pompe manuelle à un cylindre de commande, l'huile refoulée par la pompe haute pression pouvant refluer dans un réservoir lorsque le distributeur est en position neutre et une soupape de court-circuit, destinée à réaspirer de l'huile sous pression, étant montée entre chaque menant à la pompe manuelle et une canalisation de reflux. Le distributeur 8 en position neutre établit la communication entre un côté de la pompe manuelle 3 et une chambre 23 du cylindre de commande 24 tandis qu'il bloque l'autre chambre 22 de ce cylindre. Application en particulier aux véhicules de chantier pour éviter les phénomènes de battement dans le circuit hydraulique
