2. Description of the Prior Art According to East German Patent No. 209 350, a liquid-cushion carrier with a pressure-regulating device is known, in which the function chamber is provided on the edge side underneath the support platform as a sealing element. Is bounded by the seal ring and is subjected to pressure by the inlet valve. The control pressure chamber on the upper side of the sealing member is subjected to a pressure action by using a pressure control device, and a limited feeding height of the sealing member is obtained. The pressure balance between the functional chamber and the control pressure chamber is then established by means of the pressure control device via the connection channel.

A disadvantage of this solution is that the pressure medium always provides a constant supply to the function chamber, irrespective of the amount of leaking liquid, which causes a pressure increase in the function chamber of the carrier. This increase in pressure is reduced by periodically flowing off at the seal member. This results in a vibrating mechanical process, the result of which increases liquid consumption. There is no pressure regulation to ensure optimum sliding of the carrier by the distance-related control of the inlet valve, since this pressure regulation is distance-dependent and pressure-independent. This is because it does not depend on

According to the invention, this problem is achieved by means of a liquid pressure P via an inlet valve which closes in a time-dependent manner.
1 is created in the control pressure chamber and at the same time liquid pressure P 2 is created in the function chamber via the pressure control valve. The pressure control valve consists of a regulating device with a direct connection to the function chamber and a comparison and evaluation device connected to the control pressure chamber. The control device and the comparison and evaluation device are interconnected via a setting member so that a valve control chamber is produced. In the valve control chamber, the pressure state of the control pressure chamber or the function chamber is predominant, and as a result, the setting members that are deflected depending on the pressure are deflected according to the predominant pressure ratio P 1 : P 2. obtain. Optimal sliding of the liquid carrier is achieved when the pressure P 2 in the function chamber is greater than the pressure P 1 in the control pressure chamber. This control characteristic is realized by the equation P 2 = P 1 (1 + a) with the constant value a.
The constant value a is embodied by the provision of comparison and evaluation devices.

On the other hand, the difference P 2 > P 1 between the pressure in the function chamber and the pressure in the control pressure chamber prevents the annular piston seal from being pressed against the sliding surface and thus from increasing the starting force.

In the event of leakage losses, for example conditioned by bottom non-planarity, a great deal of the pressure medium required for optimum sliding conditions is subsequently supplied. That is, the required pressure P 2 in the function chamber is kept constant regardless of the liquid consumption. In the case of electrical control, signaling for signaling the pressure state takes place via electrical pressure receivers in the control pressure chamber and the function chamber, connected to the comparison and evaluation device.
The connection to the regulating device regulates the constant pressure holding in the function chamber.
