Abstract

Ce vérin est du type de ceux dans lesquels l'élément mobile est immobilisable axialement à l'aide d'un ou de plusieurs éléments. Dans le vérin selon l'invention, le ou les éléments d'immobilisation 31 sont aptes à être sollicités par un fluide sous pression à l'intérieur d'un cylindre de blocage 16 entourant la tige de piston 13 de façon étanche et ce, de telle manière qu'il(s) libère(nt) la tige de piston lorsque le fluide est admis à l'intérieur du cylindre et qu'il(s) l'immobilise(nt) lorsque l'arrivée du fluide est interrompue. On obtient ainsi une construction simple et peu encombrante.This jack is of the type of those in which the mobile element can be immobilized axially using one or more elements. In the jack according to the invention, the immobilizing element or elements 31 are able to be urged by a pressurized fluid inside a locking cylinder 16 surrounding the piston rod 13 in a sealed manner and this, of such that it (s) release (s) the piston rod when the fluid is admitted inside the cylinder and that it (s) immobilize (s) when the flow of fluid is interrupted. A simple and space-saving construction is thus obtained.
