Description: |
| Abstract:
My invention relates, principally, to that class of injectors in which the water receives io successive impulses from two or more jets of steam arranged in the same axial line, the velocity of the water being continually accelerated without being diverted from its course until it has acquired the velocity requisite to enable it to enter the boiler, but is also applicable to injectors having but one steam jet under suitable conditions. It is an object of my present invention to make an injector which shall be automatic in its action under variable conditions of water- supply and steam-pressure. and that shall be capable of restarting itself if from any cause the jet should be broken as soon as the disturbing cause is removed; and to this end my invention consists in providing an injector with a forcing combining-tube and a water-chamber provided with a water-inlet port and an over- flow-port which communicates with the atmosphere, which chamber contains the receiving and overflow openings of this combining-tube, in combination with a forcing steam-nozzle which terminates forward of the receiving end of the combining-tube; and it further consists in an annular lifting steam- nozzle, an annular lifting combining-tube, a central forcing steam-nozzle, and a forcing combining-tube, the discharging and of the forcing steam-nozzle being forward of the lifting combining-tube; and it further consists in an annular lifting steam-nozzle, an annular lifting combining-tube, a central forcing steam-nozzle, and a forcing combining- tube, the discharging end of the forcing steam- nozzle being forward of the receiving end of the forcing combining-tube; and it further consists in an annular lifting steam-nozzle, an annular lifting combining-tube, a central forcing steam-nozzle, a forcing combining-tube provided with a forward overflow-opening, a rear overflow-opening located at a point in the rear of that where the diameter of the, tube contracts to less than nine-tenths that of the discharging end of the steam-nozzle, with one or more intermediate overflow-openings, and an overflow-chamber in which all the overflow-openings are located.
Claim:
A forcing combining-tube and a water-chamber provided with a water-inlet port opening into and an overflow-port opening out of said chamber, which chamber contains the receiving and overflow openings of this combining-tube, in combination with a forcing steam-nozzle which terminates forward of the receiving end of the combining-tube. |
