Abstract
Cette invention concerne une pompe ou un moteur à débit variable comportant un plateau oscillant conjugué à une valve de commande pilotée, prévue sur le carter de la pompe. Il est prévu dans cette valve un boisseau et un tiroir. Le boisseau est relié au plateau oscillant par une tringlerie de rappel qui est constituée par un arbre 105 monté sur l'axe de pivotement Y du plateau oscillant Cet arbre attaque le plateau par une extrémité et pénètre par son autre extrémité dans la valve de commande 32 à travers le carter 12 de la pompe. Il est relié au boisseau 62 de la valve par des organes 118, 122 placés à une certaine distance radiale de l'axe de pivotement du plateau.
