摘要: A spray nozzle for gun forming a polyurethane layer on surface by spraying the reaction components obtaining this polyurethane. piece (21) with funnel-shaped cavity (27) is connected to supply channel (19) of and flows out in cylindrical (29) which connects opening 22. core (17) detachably placed allows and/or already formed be fed according screw or whirling movement through opening. The has conical part rests against an inner wall cavity. Formed are spiraled grooves (23) impart motion communication respective borings (40) open into at common point. diffuser (33) (22) realize divergent liquid jet, having slanting extend from (23).
