The disclosure concerns a supporting device for a mobile part which is subjected to dynamic forces, and which relieves the normal support bearings of the necessity of handling these unusual loads. The device comprises a support element which adjoins the mobile part, and hydraulic control means which causes that element to supply a constant, relatively small supporting reaction under normal conditions, which may produce slow displacements of the mobile part, and to supply an increased or decreased reaction, depending upon the direction of movement, when the mobile part is displaced rapidly by the dynamic forces. |
