After the steam from nozzle 21 has picked up the water of chamber B, its energy--if at approximately full pressure--is not nearly exhausted, and as the jet passes through tubes 23, 24 and 24A, it first induces a vacuum in chamber A; then, if emergency valve 35 is open, as it normally should be, and if the water supply valve 13 is fully open, inlet valve 19 will rise and permit feed water to fill chamber A, where it will be picked up by the main jet at the apertures between the tubes, and in these tubes, 23, 24 and 24 A, will absorb the remaining energy of the steam and thus increase the capacity of the injector to the maximum. Understanding this, it should be plain that if the steam pressure should fall very much below the maximum its decrease in energy would result in its ceasing to combine with the water of chamber A, inlet valve 19 would seat, and the injector would be working at a reduced capacity--the capacity of the water supply through the orifice around nozzle 21. Q. If the overflow valve (technically, the heater cock check), 86, should leak what would be the result? A. The action of the jet through tubes 23, 24 and 24A could not produce a vacuum in chamber A, as air would be drawn in through valve 86, and ...
