THE KORTING INJECTOR.

Fig. 4.

An examination of [Fig. 4] will show that this injector is a double-tube instrument; the first tube being proportioned for raising and delivering the water under pressure to the second one, which completes the operation of forcing the water into the boiler. This arrangement enables the injector to be worked through a wide range of steam-pressures without any adjustment of parts. By making the first tube proportionately small, a high power of suction is obtained, which enables the injector to feed water of such high temperature that it may be delivered into the boiler above the boiling-point. The Korting injector is operated entirely by one handle, and requires no instruction to teach its working. The feed is regulated by the patent combined regulation-valve and dirt-stop, which regulates the supply of water, and prevents the possibility of dirt reaching the injector.
