As you know water will boil below 1barg "cavitation" this how eddie current can produce very low pressures.
Injector works the same way.http://en.wikipedia.org/wiki/Eductor-jet_pump High pressured liquid or gas create high speed and low pressure. Probably, this happen when we have leak. Ammonia leak create high speed and suck air and this mixture will go away from the leak, but not in opposite direction.
