CSF TYPE FOAM GENERATOR WITH COUNTER SWIRLING FLOWS Russian patent published in 2011 - IPC A62C31/02 

FIELD: fire-fighting means.

SUBSTANCE: invention relates to fire-fighting equipment. A CSF type foam generator with counter swirling flows comprises a body with swirling chambers and an output-perforated plate; the body represents a connection holed to supply an aqueous foaming agent solution from a main line, and a cylindrical coaxial bushing rigidly connected thereto and having an outer thread which in turn is successively connected coaxially to a straight case. The bushing comprises three internal cavities sequentially coupled and coaxial to the body: a confuser, a cylindrical cavity ejecting air through at least three tangential channels formed therein, and a diffuser coupled with the case which comprises two edge lines ejecting air through at least three tangential channels into its cylindrical cavity. The case is closed by means of a sleeve nut with a perforated circular plate.

EFFECT: more effective fire extinguishing by increasing a spray and highly dispersed spray fluid.
