Abstract
A systemfor securely blocking relative translational movement between a cylindrical shaft and an element, includes a blocking elementin which an immobilization elementis arranged, the immobilization element being associated with a viscoelastic fluiddisposed between the blocking elementand the immobilization elementin such a way that translational movement is blocked when the viscoelastic fluidis pressurized in the blocking cylinder and translational movement is possible when the viscoelastic fluidis no longer pressurized. An actuating cylinder equipped with such a secure blocking system is also described.
