This action is probably the same as that of a siphon,which will continue to work when once charged, but cannot start unless the pipe is first being a vacuum at some point of the delivery-tube when the jet is established and the injectoris at work, this acts in a similar manner to the long leg of an ordinary siphon, and the flow The Non-Adjustable Injector, with fixed Xozzles, in connection with a Lifting Attachment, 2426 and 2427.—Attached to one side of this injector is an ejector or steam-siphon which drawswater, when lifted by the admission of steam, through the combining-tube, and discharges it throughthe orifice of the lifting attachment, through which also the waste-overflow takes place. This injector INJECTORS. 169 has a check-valve connected to it, also a steam-stop valve which can be opened wide by half a revo-lution of the lever on the stem. In connecting the injector, since it has fixed nozzles, a water-supplyvalve must be provided, and, as already .remarked, a second check-valve in the delivery-pipe andanother steam-stop valve are desirable. In starting this injector, steam is first admitted to the lifting-nozzle, the water-supply valve beingadjusted so as to deliver about the maximum amount of water corresponding to the steam-pressure;and as soon as solid water issues from the lifting-nozzle, the steam-valve is to be opened slightlyuntil the jet is established, when the full steam-
