Beschreibung
Zusammenfassung:	Apparatus (20) for injection of fluid into extrusion system components such as a preconditioner (24) or extruder (100) is provided, preferably as a composite assembly including a fluid injection valve (52) and an interconnected static mixer section (54). Alternately, use may be made of the fluid injection valve (52) or static mixer section (54) alone. The invention greatly simplifies the fluid injection apparatus used in extrusion systems, while giving more efficient absorption of thermal energy with a minimum of environmental contamination, and the ability to inject multiple streams into the extrusion systems. L'invention concerne un appareil (20) pour injection de fluide dans des composants de système d'extrusion tels qu'un préconditionneur (24) ou une extrudeuse (100), de préférence en tant qu'ensemble composite comprenant une vanne d'injection de fluide (52) et une section de mélangeur statique interconnectées (54). Alternativement, on peut utiliser la vanne d'injection de fluide (52) ou de la section de mélangeur statique (54) seule. L'invention simplifie considérablement l'appareil d'injection de fluide utilisé dans des systèmes d'extrusion, tout en fournissant une absorption plus efficace de l'énergie thermique avec un minimum de pollution de l'environnement, et la capacité d'injecter plusieurs flux dans les systèmes d'extrusion.
