Beschreibung
Zusammenfassung:	jet facilities. SUBSTANCE: active nozzle flow passage is formed by two cones, first being made with cone angle equal to 8° ± 1° with ratio of maximum diameter € to small diameter €1 along compressed gas flow equal to 1,5 ± 0,5 . Second cone is made with cone angle equal to 4° ± 1° at ratio of maximum diameter €1 to small diameter d along compressed gas flow equal to 2 ± 0,5 . Cone of diffuser is made, relative to cones of active nozzle with convergent parts towards each other with cone angle equal to 8° ± 1,5°, at ratio of maximum diameter €2 to small diameter d1 equal to 3 ± 1. Point "c", projection of vertex of second cone of active nozzle is located in diffuser cone. EFFECT: increased efficiency. 1 dwg
