Abstract

Ce dispositif, conçu pour un vérin à double effet alimenté par sa tige, comprend un alésage creusé dans le piston, d'axe parallèle à celui du vérin. Une communication permanente existe entre le fond de l'alésage et le passage de la tige du vérin alimentant l'une des chambres, tandis qu'une autre communication permanente relie la région de l'alésage opposée à son fond et l'autre chambre du vérin. Une autre communication, avec un clapet anti-retour, est prévue entre la région centrale de l'alésage et le passage précité, une douille de cette communication. Une petite tige, montée coulissante suivant l'axe de l'alésage, comporte une tête guidée dans la douille, et un ressort est interposé entre la douille et une bague portée par la petite tige, celle-ci coopérant en fin de course avec le palier du vérin. Le dispositif s'applique au vérin de poussée dans une perforatrice.
