Title
(EN) SELF REGULATING FLUID BEARING HIGH PRESSURE ROTARY RETARDER NOZZLE
(FR) BUSE RETARDATRICE ROTATIVE HAUTE PRESSION À PALIER FLUIDE AUTORÉGULATEUR
Abstract
(EN) A rotary nozzle having a rotating shaft operating within a cylindrical housing is balanced by allowing passage of a small amount of pressurized fluid to be bled to an area between the outside of the opposite end of the shaft and the inside of the housing where the fluid force acts axially in an opposing direction upon the shaft to balance the axial inlet force exerted by the pressurized fluid. The balance of axial forces is self-regulating by controlling escape of the fluid through a tapered or frusto-conical region between the shaft and housing. A plurality of centrifugal weight segments around the inlet end of the shaft are thrust outwardly against the cylindrical housing to retard rotational speed while pressurized fluid around the centrifugal weight segments provides a fluid bearing between the weights and the housing.
(FR) L'invention concerne une buse rotative comprenant un arbre rotatif fonctionnant à l'intérieur d'un logement cylindrique, qui est équilibrée par le fait de laisser le passage d'une petite quantité de fluide sous pression pour qu'elle soit purgée vers une zone entre l'extérieur de l'extrémité opposée de l'arbre et l'intérieur du logement où la force du fluide agit axialement dans un sens opposé sur l'arbre pour équilibrer la force d'entrée axiale exercée par le fluide sous pression. L'équilibre des forces axiales est autorégulé par le contrôle de l'échappement du fluide à travers une zone conique ou tronconique entre l'arbre et le logement. Plusieurs segments de poids centrifuges autour de l'extrémité d'entrée de l'arbre sont poussés vers l'extérieur contre le logement cylindrique pour retarder la vitesse de rotation tandis que le fluide sous pression autour des segments de poidscentrifuges assure un palier fluide entre les poids et le logement.
