Abstract
A gas/liquid mixer in which intermeshing gears are caused to rotate and establish mixing, by pressure of the fluids being mixed. The gears are mounted for rotation in a gear chamber and interengage in a meshing zone of the chamber. A gas is introduced into the chamber through a gas inlet which is adjacent to one end of the meshing zone. A liquid inlet enters the chamber between the gas inlet and an outlet which is positioned adjacent a second or opposite end of the mixing zone. The gears are rotated in the chamber by the introduction and expansion of the gas and liquid in the spaces between the gear teeth. Flow regulating means controls the gas/liquid ratio. The apparatus is useful, among other purposes, for mixing a soluble gas with molten hot melt adhesive, directly adjacent the nozzle of a dispenser for preparing a hot melt foam.
