    摘要: An ejector has: a motive flow inlet (40); a secondary flow inlet (42); an outlet (44); a motive nozzle (204); a diffuser (118); and a control needle (132) shiftable between a first position and a second position. The ejector comprises: an inlet body (210; 400) bearing the motive flow inlet and the secondary flow inlet; a diffuser body (212) forming the diffuser and bearing the outlet; a motive nozzle insert (204) forming the motive nozzle in a compartment (240) in the inlet body; and a needle guide insert (270) in the motive nozzle insert. The inlet body has a first end (230), a second end (232) and a lateral perimeter (234) between the ends. The compartment (240) extends inward from the inlet body second end (232) and is in communication with the motive flow inlet (40) and secondary flow inlet (42).
