Abstract
Cojinete hidrostático de árbol giratorio, que comprende un circuito de sustentación que incluye, alrededor del citado árbol, cámaras de sustentación opuestas que reciben fluido bajo presión, y que tienen una fuga permanente respecto al árbol, un circuito de detección de posición radial del árbol en el cojinete, que incluye, alrededor del árbol, cámaras de detección opuestas, que reciben fluido bajo presión, y que tiene una fuga permanente respecto al árbol, medios de subordinación del árbol en posición, accionados por el circuito de detección y que actúan sobre el circuito de sustentación, comprendiendo los citados medios de subordinación un distribuidor de órgano móvil, adaptado para alimentar las cámaras de sustentación opuestas, por mediación de estrangulaciones que varían en sentido inverso, a uno y otro lado de su posición de equilibrio, siendo el citado órgano móvil del distribuidor solidario en movimiento de un órgano móvil corrector, sometido a las acciones opuestas de la presión defluido que reina en las cámaras opuestas del circuito de detección.
