Abstract
An hydraulic energy dissipater with multiple working ratios, of the telescopic type, comprising a member with a variable cross-section, penetrating into a bore provided on the bottom of a piston and into a chamber provided inside the rod of the piston, which controls, as a function of its position with respect to the bore, the passage of fluid between two working chambers, either through weakly loaded valves or through more strongly loaded valves. The invention is applied more especially to the damping of yaw movements of bogies of railway rolling stock.
