The injector was patented in 1858 by Giffard, aneminent French engineer, and was introduced intothis country in 1860. There is a great diversity of opinion as to the theoryof how an injector works, yet that generally acceptedis that an injector works because the great velocity ofescaping steam has the power to impart sufficientvelocity to the feed water to overcome the pressure ofthe boiler. In other words, a jet of steam, under ahigh velocity, strikes the column of water, and,mingling with it, carries it on into the boiler, thewater in the boiler being a passive body. Technically speaking, the kinetic, or moving,energy of the jet of combined steam and water over-comes the static ener
