ABSTRACT:
A diffuser device for use in disseminating air or other gaseous fluid under pressure characterized by wall structure at least a portion of which is formed of impermeable material having a multitude of normally sealed microscopic ruptures. Said wall structure, at least in the area of said ruptures, is characterized by the ability to flex when the interior wall surface thereof, which defines the diffuser chamber, is filled with air or other gaseous fluid under a predetermined level of pressure. Said ruptures are so designed that as long as the required air pressure is maintained they form a multitude of jet-like flow passages each of which has an exceedingly small diameter. Consequently, as long as the pressure level is maintained, the air will move from the diffuser chamber, by way of said microscopic ruptures, in the form of a multitude of very fine, relatively minute, air jets which on entry to a surrounding body of liquid, for example, will form air bubbles which are correspondingly of extremely small, relatively micro-miniature size. The material of the diffuser wall structure is such that, when the air pressure falls below the required level, the microscopic ruptures will automatically reseal.
Preferred embodiments of the invention are distinguished by the diffuser wall structure being comprised in part by an integrated frame the respective end portions of which form end walls and are spaced by a relatively narrow integrally connected strip which is apertured and has a trough-like form.
