Abstract
Sealing device for an hydraulic energy dissipator of the telescopic type, formed by a seal comprising a cylindrical ring which grips the rod of the piston and which is extended by a fluid-tight bellows so as to permit axial movement of the seal in its housing following small amplitude movements of the rod. The device is useful for railway suspension shock absorbers.
