| 摘要 |
Device consisting in forming, in the mixing chamber, a hole or passage for the coupling of a pneumatic elbow or nozzle via which pressurized air is injected into the mixing chamber, the turbulence of which facilitates the mixing of the chemical components inside the chamber and the subsequent entrainment of the foam formed towards its outlet opening. The invention has made provision for improving the catalyzing action of the device, for the air-entry passage to be located, advantageously arranged, in a zone upstream of that of the passages for entry of the component fluids of the foam with respect to its outlet opening. <IMAGE>
