The steam chest is common to bothhigh and low-pressure cylinders, being open fromend to end and serving the purpose of a receiver. The valves are hollow and permit an unrestrictedflow of steam through the steam chest. There beingno receiver pipe on these engines, the smoke-box isfitted up with steam pipes and exhaust pipe exactlythe same as in simple 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 steam.
