Abstract

Ce dispositif comprend une pompe dont chaque plongeur 59 comprend sur sa surface latérale et suivant toute sa périphérie une rainure circulaire 60. Dans le corps 1 est ménagé un deuxième canal 26 servant à amener le liquide de commande et en communication avec ladite chambre 23 et dans lequel est placé, avec possibilité de déplacement, un plongeur à ressort auxiliaire 61 dont la queue 62 coopère, lors de l'amenée du liquide de commande par ledit canal 26, avec la surface latérale dudit plongeur 59.
