Giesl ejector

A Giesl ejector is a suction draught system for steam locomotives that works on the same principle as a feedwater injector. This ejector (German: Ejektor, Flachschornstein or Quetschesse) was invented in 1951 by the Austrian engineer, Dr. Adolph Giesl-Gieslingen. The Giesl ejector ensures improved suction draught and a correspondingly better use of energy. The existing blastpipe in a locomotive is replaced by several, small, fan-shaped, diverging blast pipes, from which the diffuser gets its flat, long, drawn-out shape.
