through the injector the pressure at the overflow gap a
between the combining and delivery nozzles b, c is atmo-
spheric, but if said ratio is too great or too small tlie pres-
sure thereat is respectively above or below that of the
atmosphere. If the said pressure is greater than atmo-
spheric, there is an overflow of water into the overflow

chamber d; the pressure thereby produced in said chamber
forces the combining nozzle b towards the steam nozzle c,
and so restricts the annular water inlet f. If, however,
the pressure at the gap a is less than atmosplieric, a
vacuous condition will be created in the overflow chamber,
