Abstract
An anti-roll device comprises a bar coupled to two links, a hydraulic control circuit (CC) and actuating means (MAC) comprising a casing (CR) defining the chamber (CH) subdivided into a first (P1) and a second (P2) part by a piston (PI), and comprising first (ES1) and second (ES2) inlets-outlets communicating with the first (P1) and second (P2) parts and an intermediate inlet-outlet (ES1) communicating with the first part (P1) or with the second part (P2) depending on the position of the piston (PI). These actuating means (MAC) adopt a disengaged state or block state in whatever position of the piston (PI), according to the accessibility status of the first (ES1) and second (ES2) inlets-outlets and of the intermediate inlet-outlet (ES1). The control circuit (CC) controls the accessibility statuses according to the commands received.
