Abstract
Dispositif utilisant un embrayage auxiliaire pour arrêter l'arbre à manivelles en position haute du coulisseau. Le moteur 15 entraine l'embrayage auxiliaire à griffes 45 par l'intermédiaire de l'embrayage principal 21 et du train d'engrenages 19, 43. Le disque mené de l'embrayage 45 est déplacé axialement par un piston 55, un ressort 67 et l'air de la chambre 59, fourni par la source 35. Les ouvertures 71 et 77 sont alignées verticalement quand l'arbre à manivelles 11 maintient le coulisseau 7 en position haute. Cette position est assurée par la coopération de l'interrupteur 83, du doigt 85 et de l'électrovalve 81. Un arrêt sans secousses du coulisseau est assuré par le dispositif 25 d'équilibrage à deux pistons.
