A hydraulic device includes a cylinder, a piston that is able to move in the cylinder, and a segment which is interposed between the cylinder and the piston and which includes at least one leakage duct that is configured to generate a hydraulic film, between the segment and the piston, reducing friction and to orient a hydraulic flow leaving the leakage duct which causes the segment to rotate about the piston.

Hydraulic device comprising a segment having at least one through-hole configured to promote the rotation of said segment

A system comprising a discharge valve that allows some of the fluid generated by a fluid generating source and intended for a drive torque generating member for a rotary element of a mechanical device to be removed so as to limit the corresponding rotational speed, this being done for a length of time that allows a thermal gradient to be reduced sufficiently that a phenomenon of deformation of said rotary element can be prevented.
