Abstract

See full text

The present invention relates to a system comprising: a shaft having a distal end and a proximal end; a casing defining a housing in which a hydraulic device is rotatably mounted on the shaft; and a sealing element comprising a low pressure dynamic sealing means and a reinforced dynamic sealing means formed by a static seal tightly mounted on a friction pad, such as to isolate the dynamic sealing means from the rotating hydraulic device, said sealing element defining a discharge chamber between the dynamic sealing means and the reinforced dynamic sealing means, which discharge chamber is connected to a drain via a pipe arranged on the surface of the shaft, between the hydraulic device and the shaft, so as to discharge the fluid located in the discharge chamber, such that said discharge chamber is not subjected to the pressure in the casing of the hydraulic device.
