Abstract

Cette machine hydraulique à vis (pompe à vis ou moteur à vis) comprend un rotor hélicoïdal moteur et un ou plusieurs rotors hélicoidaux libres, chaque rotor hélicoïdal libre étant pourvu d'un plongeur d'équilibrage monté dans un manchon. La face du plongeur d'équilibrage qui est la plus éloignée de l'hélice est soumise à la pression régnant à l'extrémité opposée du rotor hélicoïdal libre qui s'applique à une première surface dont la superficie est plus faible que la superficie nécessaire pour équilibrer le rotor hélicoïdal libre contre la force créée par la différence de pression entre le côté ou règne la haute pression et le côté où règne la basse pression, et est soumise à une pression située entre la pression élevée et la pression basse qui s'appliquent à une seconde surface dont la superficie est telle que la somme des superficies de la première surface et de la seconde surface est plus grande que la superficie nécessaire pour équilibrer le rotor hélicoïdal libre contre la force créée par la différence de pression.This hydraulic screw machine (screw pump or screw motor) comprises a helical motor rotor and one or more free helical rotors, each free helical rotor being provided with a balancing plunger mounted in a sleeve. The face of the balancing plunger which is furthest from the propeller is subjected to the pressure prevailing at the opposite end of the free helical rotor which applies to a first surface whose area is smaller than the area required for balancing the free helical rotor against the force created by the pressure difference between the high pressure side and the low pressure side, and is subjected to a pressure between the high pressure and the low pressure that apply to a second surface the area of which is such that the sum of the areas of the first surface and the second surface is greater than the area required to balance the free helical rotor against the force created by the pressure difference.
