Abstract

This invention relates to a device for supporting a body on a structure, employing a film of pressurised fluid, constituted by a conduit feeding pressurised fluid, which connects said film to a source of pressurised fluid, whilst a restriction is disposed on said conduit, wherein the structure is constituted by a main frame which comprises a cavity and by a male element which is introduced into said cavity and is delimited by a male surface which reproduces, at least partly, the female surface delimiting the cavity, said male surface of the element is constituted by a wall which is at least partly inclined with respect to the straight line perpendicular to the central zone of the film and the male element is coupled with the main frame of the structure by a link means adjusting its position with respect to said frame in a direction substantially perpendicular to the central zone of the fluid film, whilst the restriction is constituted by the space between said inclined wall of the element and the main frame of the structure.
