Abstract
A porous wall through which a flow of gas is established forming a layer supporting a liquid mass is strengthened partly to stiffen it and partly to control the shape of the lower surface of the supported liquid. Chambers containing different pressures can be formed, and possibly, separated by some of these strengthening parts to improve the equalisation by reducing the pressure at the center. Finally, capillaries may pass through the plate to measure the pressure or provide additional equalisation of the thickness of the layer by a suction device.
Claims8
Porous wall of a device for supporting a liquid by means of a gaseous layer resulting from the flow of a gas through at least one capillary that passes through the wall, wherein said device has a strengthening structure on a side of the wall opposite to the gaseous layer containing ribs, and a pressure measurement device in fluid communication with said at least one capillary.
Porous wall of a device for supporting a liquid by means of a gaseous layer resulting from the flow of a gas through at least one capillary that passes through the wall, wherein said device has a strengthening structure on a side of the wall opposite to the gaseous layer containing ribs, and a pressure regulating device in fluid communication with said at least one capillary.
