Abstract (en)
The two liquids (F1, F2) are fed separately to the spray head as is the propellant gas. The ducts are concentric at the spray head and each liquid is separately mixed with the propellant and the separate mixture are directed onto a shaped flange (16) with a lip (17) which causes atomisation. A mixing chamber (2) with alternate expansion- and compression stages mixes the two spray types. The final mixture is expelled via a conical, converging jet (20) to provide a spray cone. The propellant and liquid mixing is provided by the shaped ducts which merge the two flows. The separate mixed flows are directed onto the shaped flange via exit holes arranged alternately around the spray head.
