Abstract
A fluid-cushion supporting arrangement for horizontal conveyance comprises a supporting platform having a center and a distal portion; a flexible angular sealing element arranged under the platform in the region of the distal portion and forming a sealing piston. The sealing piston has a substantially horizontal leg which extends toward the center and forms together with the supporting platform a fluid chamber, and a substantially vertical leg which forms together with the supporting platform a control pressure chamber. The vertical leg is vertically and adjustably inserted in the control pressure chamber. An inlet valve is provided for supplying fluid into the fluid chamber. A pressure-regulating arrangement in fluid communication with the fluid chamber and the control pressure chamber regulates the fluid pressure. The vertical leg comprises a plurality of reinforcement elements including at least one metallic strip.
