Abstract:
A foam distribution nozzle comprising:a supply tubing for supplying foam from a supply conduit, having a longitudinal axis; a barrel being rotatably attached to the supply tubing and defining a passageway therein, the passageway of the barrel being at angle to the longitudinal axis of the supply tubing; the barrel having at least one orifice which, upon forced flow of the foam, delivers a stream of the foam along a trajectory having a component that is tangential to a circular path coaxial with the longitudinal axis of the supply tubing such as to cause a rotational movement of the barrel; and a central bearing which includes a thin-shaft spindle having a first portion co-axial with the supply tubing to rotatably mount the barrel and defining an axis of rotation, and a second portion for engaging the supply tubing; wherein the sum of all the cross-sectional areas of the at least one orifice is not less then &frac13; of the cross-section of the supply conduit, and wherein the barrel has two orifices, said orifices being disposed on opposite sides of the axis of rotation, and each orifice delivering a stream of the foam in opposite directions.
