Abstract

Régulateur de pression centrifuge destiné à commander la pression de sortie d'une pompe à fluide Ce régulateur comprend un corps 19 rotatif dans une cavité dont la vitesse de rotation détermine la pression de sortie de la pompe, un alésage diamétral 25 ayant deux parties de diamètre differents recevant chacune un piston 26, 27, une butée 28 définissant avec les pistons et la paroi de l'alésage une chambre de trop-plein, un orifice de trop-plein 30 qui fait communiquer la cavité et la chambre de trop-plein et dont la section est commandée par le piston 27, un ressort 32 rappelant le piston 27 dans le sens de réduction dudit orifice, une sortie prévue pour la chambre de trop-plein et une entrée pour la cavité, reliée à la sortie de la pompe, et un moyen pour limiter la vitesse de déplacement des pistons suivant la vitesse et/ou la pression de sortie.
