Figure 136 2QS LOCOMOTIVE ENGINEERING Piston Valves. On the high-pressure cylinders the valves are arranged for internal admission, and on thelow-pressure cylinders for external admission. An ex-amination of Fig. i;5 will show that this design ofvalves allows steam to be admitted to the same side ofeach piston by means of the crossed ports on the high-pressure cylinder, the valves being shown as admit-ting 137 Low-Pressure Cylinders. The saddle and cylinders are shown in Fig. 137 in front view and vertical sec-tion, in which the coring is shown for steam andexhaust passages. The saddle has an opening c<:redinto the steam-pipe passage, extending from front toback on each sice, where there is a circular flange forconnection to the short length of steam oioe which ^ XX extends from front of saddle to the high-pressurecylinder. Coring this passage through from end toend of saddle makes the cylinders interchangeable foruse on either side. Starting Valve. To work the engine, simple or com- COMPOUND LOCOMOTIVES 259 pound, at will, the starting valve shown in Fig. 138 is used, this valve being secured to the side of steam I chest over the high-pressure cylinder, and having direct communication with the steam passages into that cylinder. The by-pass valves for the high- i pressure cylinders are also contained in the casing of I this starting valve and are worked in connection with the
