Abstract
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.
