What is the function of the strainer? THE DEAD ENGINE FEATURE. The Dead Engine feature shown in Fig. 295 isfor the operation of the locomotive brakes when thepump on a locomotive in a train is inoperative throughbeing broken down, or by reason of no steam. Fig. 322shows the combined strainer, check valve, and chokefitting. ^As these parts are not required at other times, acut-out cock is provided. This cock should be keptclosed except under the conditions just mentioned. Theair for operating the brakes on such a locomotive mustthen be supplied through the brake pipe from the loco-motive operating the train FIG. 322. COMBINED AIR STRAINER AND CHECK VALVE With the cut-out cock open, air from the brake pipeenters at BP, Fig. 322, passes through the curled hairstrainer, lifts check valve 4, held to its seat by a strongspring, passes through the choke bushing, and out atMR to the main-reservoir, thus providing pressure foroperating the brakes on this locomotive. The double- 723 724 LOCOMOTIVE ENGINEERING heading cock should be closed, and the handle of eachbrake valve should be in running position. Where ab-sence of water in the boiler, or other reason, justifieskeeping the maximum braking power of such a loco-motive lower than the standard, this can be accomplishedbv reducing: the adjustment of the safetv valve on thedistributing valve. It can also be reduced at will by theindependent brake valve. The strainer protects the check val
