Abstract (en)
[origin: US5921471A] A head for generating and spraying foam is provided. The head is particularly useful in a fire extinguisher. The head includes a nozzle for spraying foam in a praying direction, at least two conduits for supplying a fluid, and a boss. A. wall at the outlet end of each conduit is oriented approximately perpendicular to the spraying direction. The conduits each emerge into a base of the nozzle via openings. A fluid is supplied to the conduits. During travel of the fluid to the nozzle, the fluid encounters a double deflection. The first deflection is from the wall within the conduit towards the boss. The second deflection is from the boss towards the wall of the nozzle. This double deflection path of travel causes the fluid to become completely emulsified with ambient air to create a large volume of high quality spraying foam.
