FLOW REGULATOR AND FIRE-EXTINGUISHER Russian patent published in 2007 - IPC G05D7/06 A62C13/62 A62C35/66 

FIELD: fire-fighting equipment, particularly portable fire-extinguishers.

SUBSTANCE: fire-extinguisher comprises vessel with working fire-extinguishant, fire-extinguishant displacing system, which distributes fire-extinguishant from vessel and has siphon pipe used as working liquid flow rate regulator body and spraying means connected to outlet of locking-and-triggering means connected with siphon pipe outlet. Air-tight resilient shell, which defines cavity communicated with through body channel by means of body orifice, is arranged from outer side of siphon pipe. Spring-like regulating member transversal to longitudinal through channel axis is arranged in the through channel so that the regulating member may slide via body orifice. The regulating member is in contact with resilient shell. Spring-like regulating member or two plate-like regulating members including similar plates change through channel throat in dependence of working medium pressure at regulator inlet.

EFFECT: increased reliability and response due to simplified flow regulator structure.
