Abstract
L'invention est relative à un dispositif d'arrêt d'un moteur. Sur les canalisations d'alimentation 9 et 10, entre le moteur et le distributeur de commande 7, est montée une électrovanne 48 dont l'orifice d'écoulement présente un étranglement 53, ladite électrovanne comportant une commande 38 couplée à celle du distributeur 7, de sorte qu'elle se trouve fermée lorsque le distributeur commande la rotation normale du moteur, mais se trouve ouverte 53 lors de la fermeture du distributeur, et une commande, dans le sens de la fermeture, couplée à un détecteur de position du moteur par rapport à la position d'arrêt désirée. Une application est la commande du moteur d'entraînement de tourelle pivotante d'une pelle.
