Abstract
Cet ensemble, muni d'une butée hydromécanique comportant, de façon connue en soi, un ressort 11, une bague d'amortissement 15 et son support 14, relativement auquel la bague peut effectuer un déplacement axial limité, ainsi qu'une butée 12 solidaire de la tige de piston 3, est caractérisé en ce que, lorsque la tige de piston, effectuant sa course de sortie, a dépassé une position intermédiaire prédéterminée, la bague et son support sont immobilisés axialement de façon positive, soit parce que le support est fixé au ressort, lui-même fixé, directement ou indirectement, au cylindre 1, soit parce que la bague ou son support vient s'appliquer contre une butée solidaire du cylindre.
