Abstract

Esta máquina hidráulica comprende una rueda sostenida por un árbol (5), la rueda y el eje son capaces de girar sobre un eje vertical (X5), mientras que un cojinete radial hidrostático o hidrodinámico (100) está formado, por una parte, entre una superficie radial periférica (52) del eje y por otra parte, una superficie radial interna (102) de un miembro (101) que es fijo con relación al eje vertical. El cojinete (100) se extiende entre dos bordes (121, 122), los cuales, en su operación normal, constituyen regiones de evacuación de una película de agua formada en el cojinete. Al menos una cavidad (130) está provista en el miembro fijo (101) y desemboca en su superficie radial interna (102) cerca de un primer borde (122) del cojinete. La máquina incluye medios (131, 132, 133) para poner la cavidad (130) en comunicación fluida con un volumen (V1) situado en el exterior del cojinete cerca del segundo borde (121) del cojinete (100). Esto permite evacuar hacia el segundo borde (121) una parte (E2) de la película de agua del cojinete (100) en caso de obstrucción del cojinete en las proximidades del primer borde (122).
