A hydraulic power steering device (1) having a damper valve (10) arranged in hydraulic oil circuits (8, 9) connecting an oil path selector valve (11) inside a gear box to the right and left oil chambers of a power cylinder (6), wherein the damper valve (10) comprises a spool valve, a control oil chamber (21) of the spool valve (10) is connected to a hydraulic oil feed path (18) connecting a hydraulic pump (13) which is driven by an internal combustion engine so as to deliver hydraulic oil to the oil path selector valve (11), its back pressure chamber (17) is connected to a hydraulic oil circulating path (19) connecting the oil path selector valve (11) to a reservoir tank (12), and orifices (27, 28) are provided in the connecting oil paths (22, 20), respectively, whereby, when the pressure of oil delivered from the hydraulic pump (13) rises, the opening of the spool valve (10) is increased.

L'invention concerne un dispositif de direction assistée hydraulique (1) qui possède un robinet à volet (10) placé dans les circuits hydrauliques d'huile (8, 9) reliant une vanne sélectrice de voie d'huile (11), placée à l'intérieur d'une boîte à vitesses, aux chambres à huile gauche et droite d'un vérin de commande (6). Le robinet à volet (10) comprend un distributeur à tiroir, une chambre à huile de contrôle (21) du robinet à volet (10) étant reliée à une voie d'alimentation en huile hydraulique (18) qui relie une pompe hydraulique (13) entraînée par un moteur à combustion interne de manière à fournir l'huile hydraulique à la vanne sélectrice de voie d'huile (11). Sa chambre de contre-pression (17) est reliée à une voie de circulation d'huile hydraulique (19) reliant la vanne sélectrice de voie d'huile (11) à un réservoir (12). Les voies de raccordement d'huile (22, 20) comportent des orifices (27, 28): grâce à ces orifices, lors de l'augmentation de la pression de l'huile fournie par la pompe hydraulique (13), l'ouverture du robinet à volet (10) augmente.
