label: Description
content: Features of this injector are the construction of the starting lever, which with one motion operates both the steam and overflow valves and also permits the overflow valve to close independently of the lever; a removable ring of resistant metal inserted in the combining tube at its smallest diameter to receive the corroding action of the jet at that point; and an arrangement of steam and water passages designed to prevent the raising of the temperature of the feed water to such a temperature as to deposit scale within the tubes of the injector.
