ABSTRACT:
A sealing device for a hydraulic fluid rotating machine, characterized in that between a free internal peripheral edge (126) of a rotating body (20) and a contiguous wall of sleeve (18a, 18b) around which it fits, there is mounted a fixed fluid-tight seal (120), integral with sleeve (18a, 18b), but axially movable in relation to the latter, said seal comprising an annular body (122) which fits with some play around the sleeve, a lip seal (123) turned on the side of cavity (52) of turning body (20) and being applied in a fluid-tight sealing manner on the exterior surface of the machine, and an annular radial protrusion (124) housed inside an annular groove (126) formed in the peripheral edge (116) of the rotating body, the dimensions of which are greater than those of the protrusion, thereby avoiding any friction of the protrusion with the rotating body.
