Abstract

Si propone un eiettore del tipo generalmente conosciuto ma di costruzione nuova. Il nuovo eiettore comprende un corpo avente dei fori di entrata e di uscita e una pluralità di camere di aspirazione, ognuna con due serie di ugelli di eiezione che sono disposti nelle divisorie tra le camere del corpo.FIGURA 1
