Description: |
| Abstract:
The objects of my present improvements are, first, to enable all injectors constructed for feeding steam-boilers to throw a smaller quantity of water than has heretofore been possible, and to accomplish this without in any way affecting their maximum capacity; second, to enable the instrument to draw its supply-water from a lower level without increasing the number of its parts; third, to simplify the construction of the self-adjusting injector; fourth, to enable the self-adjusting injector to lift its supply-water; and, fifth, to make the waste-orifice of the self-adjusting injector self-closing. The nature of my invention consists in the arrangement of the steam-discharge nozzles of all injectors constructed for feeding steam- boilers so that they may be elongated at the same time that the discharge-opening is being contracted; and it also consists in the construction of the divergent tube or pipe which delivers the water from the self-adjusting injector to the boiler, so that the boiler-pressure can exert but a very slight influence upon the end exposed to it, the internal construction of this pipe conforming as near as possible to that which the jet would assume when forced into a fluid at rest, in which case no lateral strain would be exerted upon the pipe, and the only pressure that could produce a longitudinal movement would be that exerted upon the edge where the parallel outside meets the divergent inside; and it also consists in the means for limiting the movement of the self-adjusting piston, so as to obtain an effective vacuum, and in closing the waste-orifice of the self-adjusting injector by the action of the injector itself; all of which is more fully explained by referring to the drawing herewith.
Claim:
The hole c in the end of the plug, which plug regulates the discharge of steam in the injector. |
