Abstract:
1. An assembly for mixing and metering a foaming agent, comprising: a hand-held fire extinguisher having a body containing a pressurized fluid, the extinguisher further having a trigger for issuing the pressurized fluid through an outlet of the extinguisher; a manifold directly attached at an inlet end thereof to the outlet of the extinguisher, said manifold having an outlet end engaging with an inlet of a flexible hose extending from said manifold; a disposable canister containing a volume of a foaming agent at any pressure up to that of the fluid within the extinguisher, said canister being releasably engaged to a communicating location of said manifold located between said inlet and outlet ends such that said manifold and canister are structurally supported by said extinguisher, the pressurized fluid output through said manifold mixing with the foaming agent withdrawn from said canister in Venturi induced fashion in response to vacuum forces generated within said manifold resulting from issuance of the pressurized fluid and prior to delivery through the hose; and a valve at said communicating location of said manifold for metering the volume of the foaming agent intermixed within said manifold with the pressurized fluid from the extinguisher.
