    A fluid-cushion supporting arrangement for horizontal conveyance has a supporting platform, a flexible angular sealing element arranged under the platform in the region of its marginal portion and formed as a sealing piston with a horizontal leg forming together with the supporting platform a fluid chamber and a vertical leg forming together with the supporting platform a control pressure chamber, a pressure-regulating device through which the chambers communicate with one another so that the fluid from the fluid chamber can act upon the control pressure chamber in a pressure-dependent manner, and first and second sensors which are parts of the inlet and the pressure-regulating element and brought in contact with the horizontal leg and the vertical leg of the sealing piston, respectively.

    This invention relates to vehicles for transporting tons of human cargo.
    Ieeston the design (patent K I46A36, class B 65 G 7/06, 1979) of the mechanism for enclosing the cushion of the transport device, the lack of which is the absence of a car
    matic pressure control in the chamber of the jet medium.
    The purpose of the invention is to increase reliability by increasing the stiffness of the fence.
    Figure 1 shows the device, a vertical section; figure 2 - node I in figure 1.
    On the supporting platform 1, the adjusting valve 2 and the inlet valve 3 are installed so that they, together with the lower sealing elements below the supporting platform 1, limit the control pressure chamber 4 and the air cushion chamber, and the stem 6 of the adjusting valve 2 enters the control pressure chamber 4 in contact with the sealing piston 7 of the sealing element and the stem 8 of the intake valve 3 enters the chamber 5 of the air cushion in contact with the sealing shoulder 9 of the sealing element.
    In order to prevent unacceptable expansion of the elastic sealing piston 7, the annular body in the lower part is provided with a reinforced textile material with a bottom 10 in quality. stiffness element. The bottom 10 has holes 11, allowing the jet medium to exit to, the supporting surface 12 and to the gap 13.
    The ratio of the pressures in the chamber 5 and the control discharge chamber 4 is established by means of an adjusting valve 2 connected to the channel 14 to the chamber, as well as to the channel 15 leading to the control discharge chamber 4.

    or by a compressor, directed through the inlet valve 3 to the chamber 5, which is filled with medium. With the creation of pressure, the jet medium flows through the channel 14 to the seat 16 of the adjusting valve 2. In a quiescent state, the sealing piston 7 of the sealing element is completely within the guide piston, limited

    supporting platform 1. Consequently, the valve stem 6 of the valve 2, spring-loaded with the upper compression spring 17, is pressed upward and relieves the lower valve spring 1.8 by means of an elastic disc 19. The seat 16 moving on the rod provides in this position a free transition of the jet: medium into the channel 15.
    In the quiescent state, the pressure in the chamber 5 corresponds to the pressure of the upper sealing piston 7 in the control pressure chamber 4.
    The sealing effect in the sealing gap 13 is complete and, with increasing pressure, increases the lifting of the supporting platform 1 with this temporary load.
    With the lift, the rod 6 of the pressure regulating device follows the sealing piston 7 of the sealing element pressed downwards, and the elastic disk 19 more and more pulls the valve spring 18 against the seat 16. This reduces the pressure in the control pressure chamber 4 through the channel 15. Dependent From the height, the pressure drop in the control plenum 4 is stabilized by means of a discharge throttle. When the predetermined height of the support platform 1 is reached, the inlet valve 3 is closed. In this transport position, a decrease in pressure acting on the sealing piston 7 in the gap 13 causes the jet medium to start passing from the chamber 5 through the holes 11 to the outside.
    During friction during transportation between the sealing element and the supporting surface 12 with loss of the jet medium, mutual adjustment occurs from the inlet valve 3 to the control valve 2.
    A further possibility of alternating adjustment of the inlet 3 and the adjusting 2 valves is provided from the outside, namely by changing the preload of the compression spring 17 and the valve spring 18. There is no need for external charging of the control medium, since the pressure in the chamber is always equal to or higher than the pressure in control piston 4 to the fault of the sealing piston 7.
