Abstract
Il flusso di liquido (2) è trascinato da un getto vapore (4) di un ugello supersonico (3) entro una camera (7) che presenta una prima parte conica convergente (8) e una seconda parte conica divergente (9); in detta prima parte conica (8) è compresa una prima apertura (10) in comunicazione con un primo condotto di scarico (11) controllato da una prima valvola (12) e, a valle della prima apertura (10), è anche compresa una seconda apertura (13) in comunicazione con un secondo condotto di scarico (14) portante una seconda valvola (15) controllata per ottenere la massima prestazione dall'iniettore.Fig. 1.
