Abstract

L'invention concerne une commande de sécurité pour rouleau compresseur automoteur à transmission hydrostatique, comportant un groupe moteur, une pompe hydraulique mue par ce groupe et montée dans un réseau hydraulique principal qui comprend un moteur hydraulique muni d'un dispositif assurant un freinage en période non motrice, des soupapes de retenue montées en pont avec une soupape de sûreté et une soupape de commande principale, et un sélectçur automatique de vitesse soit de fonctionnement, soit de ralenti. Le moyen sélecteur de vitesse est constitué par un réseau hydraulique secondaire 60 comportant des moyens 20 accouplés au régulateur de vitesse du groupe moteur et commandés par la soupape de sûreté de décompression 14 sous l'action de la soupape de commande principale 27. Applications courantes.
