ACOUSTIC FOAM GENERATOR Russian patent published in 2010 - IPC A62C5/00 

FIELD: fire-fighting equipment.

SUBSTANCE: in acoustic foam generator, which consists of pipe, supplying water solution of foam former from aggregate, tube for air supply under pressure, placed coaxially to cylindrical shell, which envelopes tip, connected with shell by means of diffuser from one side and by disk - from the other, tip is made acoustic, containing body in form of cup with bottom, in which made is cylindrical cavity for liquid supply through tube, placed on lid, in whose upper part placed is fastening element, fixing upper part of rod of rod gas-jet irradiator in nozzle, made in lid. Upper part of rod is pivotally connected with lower part of its rod by means of at least one fixing disk, made in form of at least three elastic petals, interacting with internal surface of conical lid opening. Between opening in cup bottom and external surface of lid nozzle made is a slot channel for liquid, and between internal surface of conical opening and external surface of lower rod part - ring channel for discharge agent.

EFFECT: increased efficiency of foam generator, producing foam of low factor at boundary values of its work conditions.
