Beschreibung
Zusammenfassung:	The specification discloses a spray nozzle assembly for simultaneously spraying two materials, such as the material and catalist of urethane foam. The nozzle assembly is made up of two concentric spray nozzle members defining a central path and a cylindrical path concentric to the central path. The nozzles are so arranged that the material is given a turbulent motion as it emerges from the nozzle thereby causing a mixing of the two materials. The assembly can be used without a pump connected to a source of pressure.
