Abstract:

Giffard injectors; regulating.-In a live-steam injector, an annular passage a between the usual live-steam nozzle b and the water-inlet cone c admits exhaust steam to be absorbed by the feed-water before it is impinged upon by the live steam. The supply of exhaust is regulated by a spring-pressed valve f on the exhaust passage g which is acted upon by the steam in the engine valve chest through the intermediary of the passage h, piston i, and stem j. A positively-operated valve m enclosing the valve f may also be used for regulation. The device for regulating the supply of exhaust forms the subject of Application 29,328/13. When no exhaust steam is available, the discharge from the small continuously-working ejector of a brake system may be admitted, or a throttled supply of live steam.
