ACCELERATOR VALVE, This valve is designed to assist the Brake Valve in discharging brake pipe pressure when making service \ stops on long trains to bring about a more uniform ap- , plication of the brakes, and to apply them more promptly than Fig. 287. Accelerator Valve. The Valve is perfectly automatic in its operation, be-ing governed entirely by the volume of air in the brakepipe, operating only when the train is of such a length 65i 652 LOCOMOTIVE ENGINEERING as to warrant the use of same. The operation is similarto that of the graduating mechanism in the Brake Valve,opening about four seconds after the Brake Valve han-dle has been moved to a graduating notch, and closingin about the same length of time after the graduatingvalve has closed. Fig. 287 is an outside view of the Valve showing con-nection to brake pipe and exhaust which is through thestreet ell. A sectional view is shown in Fig. 288. TheValve is bolted to the end of the divided reservoir (Fig. G 24
