Abstract

Ce dispositif, caractérisé en ce qu'il comprend en combinaison un boîtier, un cylindre formé dans le boîtier, un premier et un second piston qui sont disposés aux extrémités opposées du cylindre, une tige de piston qui s'étend à travers les pistons, ladite tige de piston traversant une paroi d'extrémité du cylindre et étant reliée à un organe de sortie, ou constituant un tel organe de sortie, une butée formée sur la tige de piston entre lesdits pistons, cette butée étant adaptée pour que les pistons puissent venir en contact avec elle lorsque la face externe de l'un ou de l'autre des pistons est exposée à la pression d'un fluide, deux autres butées prévues sur la tige de piston et adaptées pour que les pistons puissent venir en contact avec elles respectivement, lorsque les extrémités internes des deux pistons sont exposées à la pression d'un fluide, et un distributeur pour distribuer du fluide sous pression soit à l'une des extrémités du cylindre, soit à son autre extrémité, soit encore entre lesdits pistons.
