Abstract

L'invention concerne une pompe hydraulique comprenant un boîtier définissant une cavité, un orifice d'entrée et un orifice de sortie. La partie active de la pompe est constituée par un ressort hélicoïdal à spires jointives dont une extrémité est associée au boîtier alors que l'autre extrémité est susceptible d'être sollicitée en rotation de façon alternative En association avec des membranes d'étanchéité, le ressort définit dans la cavité deux chambres à volume variable reliées respectivement aux orifices d'entrée et de sortie par des valves de non retour. Un passage dans lequel est montée une autre valve de non retour assure la communication entre les chambres. Applications aux pompes destinées à couvrir de vastes gammes de pression et de débit
