Abstract (en)

[origin: EP0250781A2] A hydraulic force-transmitting element is specified, having a cylinder-piston unit and a hydraulic fluid volume which surrounds the said unit essentially concentrically, is retained in a bellows element and is connected to the cylinder chamber via a non-return valve which closes when there is pressure in the cylinder chamber. In this case, the bellows element is formed by a bellows whose one end is closely connected to the cylinder and whose other end is closely connected to the piston of the cylinder-piston unit, to form a seal in both cases and which bellows element has at least one bellows shaft with a larger external diameter and/or smaller internal diameter than the other bellows shafts. <IMAGE>
