The action of the in-spirator is controlled bya double steam valve pe-culiar to this form of in-spirator, consisting of avalve, e, within anothervalve,/. The inner one,e, is opened by a slightmovement of the lever d,which admits steam to the chamber# and to the lifter nozzle /), which starts the water flow-ing through the combining tube a into the chamber ;. Thewater pressure in this chamber raises the intermediate valve cand allows the water to tlow upward and then downward, andit escapes through the overflow valve,; into the chamber /> andout through the overtlow pipe G. When a current of this kindis once established the lever d is drawn farther toward the right, which opens the main valve /and allows steam to flowthrough the opening at I into the chamber in and through thenozzle n into the tube b. This starts the forcing current ofwater through the tube / into the chamber 0. The pressure in.

As soon as the pressure in 0 ex-ceeds the boiler pressures, the check valve p is opened and thecurrent of water flows through the feed pipe I) into the order to regulate the amount of water fed to boiler a de-vice is provided which consists of a valve, s, on the end of aspindle, r, which is operated by a handwheel, q. By thismeans the feed may be regulated from the maximum to theminimum capacity without touching the lever and without
