Abstract

Ce dispositif, qui présente l'avantage de former un ensemble compact remplissant la double fonction de limiter et d'arrêter ou d'inverser le mouvement du vérin, comporte un carter 16 monté à demeure sur une partie d'une machine dans laquelle est utilisé le vérin, carter dans lequel la butée 12 et le générateur 13 sont montés de façon réglable dans la direction axiale, relativement au carter et l'un relativement à l'autre. On peut joindre à cet ensemble un élément amortisseur hydraulique, de préférence progressif 14.This device, which has the advantage of forming a compact assembly fulfilling the dual function of limiting and stopping or reversing the movement of the jack, comprises a casing 16 permanently mounted on a part of a machine in which is used the cylinder, housing in which the stop 12 and the generator 13 are mounted in an adjustable manner in the axial direction, relative to the housing and one relative to the other. A hydraulic damping element, preferably progressive 14, can be added to this assembly.
