This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1906 Excerpt: ... the overflow flange. This contains an overflow valve, which is maintained upon its seating, while the injector is at work, by the pressure of the delivery jet being communicated to a little piston on the top of the valve spindle. The necessity for this is evident with a compound apparatus. There is a small pipe seating A close to the water regulator, which is connected by a small pipe to another pipe seating A on the live steam supply pipe. By the use of this pipe the injector may be worked when the engine is standing. The overflow pipe has a non-return valve in it, so that the atmosphere and its pressure may be kept out of the combining tube. The construction of the supplementary portion or "forcer" and the supplementary overflow valve is shown in the section, fig. 80. When the injector is starting, the pressure above the little piston of this valve, which is protected by a rubber diaphragm, is the same per square 'ill-UK-.. inch as that below the valve itself, namely, that of the steam jet in the combining cone; and as the area of the valve is greater than the area of the piston, the valve necessarily lifts. Thus the supplementary portion is quite as much a lifting and re-starting apparatus as a single injector with the flap nozzle. In order to avoid the trouble of renewing the indiarubber, the equivalent arrangement shown in fig. 81 is adopted. In this it will be noticed that a lever is introduced, against one end of which the overflow valve spindle presses, whilst the other end of the lever rests upon a small cylindrical rod, the lower end of which acts as a piston, transmitting the pressure by means of the lever to the overflow valve, instead of the small pipe shown in fig. 80. This arrangement (Metcalfe Bros.i patent) is practically indestr...
