Abstract
L'invention concerne un palier hydrostatique d'arbre tournant, comprenant, un circuit de sustentation incluant autour dudit arbre des chambres de sustentation opposées recevant du fluide sous pression et ayant une fuite permanente par rapport à l'arbre, un circuit de détection de position radiale de l'arbre dans le palier incluant autour de l'arbre des chambres de détection opposées recevant du fluide sous pression et ayant une fuite permanente par rapport à l'arbre, des moyens d'asservissement de l'arbre en position actionnés par le circuit de détection et agissant sur le circuit de sustentation, lesdits moyens d'asservissement comprenant un distributeur à organe mobile adapté pour alimenter les chambres de sustentation opposées par l'intermédiaire d'étranglements. L'organe mobile du distributeur est constitué sous forme d'élément annulaire entourant des passages d'alimentation des chambres de sustentation. Application : machines-outils.
