Abstract
La présente invention concerne un dispositif d'alimentation de moyens de manœuvre (90) d'une installation (93,94) pour véhicule automobile à direction hydraulique assistée, du genre comportant une centrale hydraulique d'assistance (17,18). Le dispositif est caractérisé en ce que la centrale hydraulique d'assistance (17,18) alimente lesdits moyens de manœuvre (90), ainsi que le distributeur hydraulique (24) de la direction hydraulique assistée du véhicule automobile, en ce qu'un bloc hydraulique répartiteur de débit (100) est interposé entre la centrale hydraulique d'assistance (17,18) et le distributeur (24) de la direction hydraulique assistée, en ce que ledit bloc (100) comporte un dispositif répartiteur de débit (30) alimenté par la centrale hydraulique d'assistance (17,18), pour répartition du débit en un débit principal circulant dans un circuit principal (3) pour alimenter la direction hydraulique assistée, et en un débit secondaire circulant dans un circuit secondaire (4) pour alimenter les moyens de manœuvre (90), et en ce qu'un dispositif de perte de charge (40) est connecté au circuit principal (3) et au circuit secondaire (4) pour réguler en pression lesdits débits principal et secondaire selon la demande de la direction hydraulique assistée.
