A hydraulic jack includes three chambers (3, 4, 5), two of these three chambers being annular and enclosing a sliding cylindrical element (8) including a first piston (9) delimiting the two annular chambers (3, 4), and a second piston (10) delimiting the third, substantially cylindrical chamber (5) which is contiguous with one of the two annular chambers (3, 4). The hydraulic jack is used in hydropneumatic suspensions for automotive vehicles.
