Abstract
Engin (1) roulant comprenant un dispositif (2) de stabilisation comprenant au moins une jambe (3) et un vérin d’actionnement de ladite jambe (3) entre une position active d'appui au sol de la jambe et une position inactive, le vérin comprenant une première chambre reliée à la source de fluide par un premier circuit de raccordement et une deuxième chambre reliée à une source de fluide par un deuxième circuit de raccordement pour permettre, à l’état alimenté en fluide de la première chambre, un actionnement du vérin dans le sens d’un passage de la jambe (3) à la position active de stabilisation de la jambe (3) et, à l’état alimenté en fluide de la deuxième chambre, un actionnement du vérin dans le sens d’un passage de la jambe (3) à la position inactive de la jambe (3), ladite jambe (3) étant configurée pour permettre, sous l’effet de son propre poids, un actionnement du vérin dans le sens d’un passage de la jambe (3) à la position active de stabilisation et lesdits premier et deuxième circuits étant chacun équipés d’un dispositif de fermeture au moins partielle du circuit associé. L'organe d'obturation du dispositif de fermeture du deuxième circuit est configuré pour passer en position fermée en fonction de la pression régnant sur le premier circuit entre le dispositif de fermeture au moins partielle du premier circuit et la première chambre du vérin.
