Abstract

Esta máquina hidráulica (1) comprende un impulsor (2) que es capaz de girar con respecto a una estructura fija (9) y sobre un eje de rotación fijo (X2), un flujo forzado (E) de agua que está destinada a fluir a través de este impulsor (2). Un cojinete hidrostático (100), que está formado, en primer lugar, entre un elemento (111) acoplado en rotación al impulsor (2) y en segundo lugar, una parte (91) de la estructura fija (9), está colocada entre una primera región (Z1) de la máquina, que está en comunicación fluida con el flujo forzado (E) y en la cual, durante la operación, prevalece una presión similar a la del flujo forzado, y una segunda región (Z2) de la máquina, que está aislada del flujo forzado mediante este cojinete.
