Abstract (en)
[origin: EP1519055A2] The fluid drive between two relatively movable components has at least one hydraulic or pneumatic drive element consisting of a hollow component (1) which is formed at least partially like a bellows. Stretch resistant ring elements (4) encompass the hollow component in each individual fold, and the stretch resistant ring on at least one side of the hollow component is connected via an extension resistant connection to at least one of the two force action sections (3) of the drive element. An independent claim is included for an articulated drive incorporating the proposed fluid drive for two components interconnected by a joint.
