Abstract

Installation avec freins chargés mécaniquement dans le sens du serrage, maintenus ouverts par des organes hydrauliques provoquant le déblocage avec pompe à air comprimé accouplée en commun avec une pompe hydraulique, au moteur de machine, avec une première soupape d'arrêt dans une conduite de court-circuit de la pompe hydraulique et une seconde soupape d'arrêt entre la pompe et les organes de desserrage des freins. Installation caractérisée en ce que les deux soupapes d'arrêt 64, 66 sont accouplées entre elles et actionnées par un organe commun 72 tel que, lors de l'ouverture de l'une, l'autre se ferme et inversement. Installation applicable à des rouleaux de cylindrage de route.
