THE STEAM INJECTOR.
forcing steam nozzle. Wlien the injector is lifting its feed
water, the steam issuing from the nozzle a acts as an
ejector to create a vacuum in the feed pipe, so as to lift the
feed water and supply it at high velocity to the steam
jet issuing from b. The area of the lifting nozzle is con-
siderably less than that of the forcer. To enable the steam
from the lifter to escape, freely when the feed water is
bøing lifted, a special overflow aperture as c is provided
between the lifter and forcer.
