Running Position. In charging the system, compressed airflows from the main reservoir to the brake valve, entering it throughpassage A, Fig. 20, and flowing to chamber A above the rotaryvalve (see cross section of brake valve. Fig. 18). Port j through. 7~3^ I Pipe. Fig. 18. Westinghouse G-6 Brake Valve in Release Position the rotary valve registers with port / in the seat, allowing air toflow to the feed valve, which is attached directly to the brake valveas shown. The feed valve reduces the pressure of the air fromthat carried in the main reservoir to that which is to be carried inthe brake pipe. From the feed valve the air re-enters the brakevalve through port i, which has two branches. One branch leads to port I in the seat through which the airflows to the cavity c in the rotary valve, thence to the equalizing 34 AIR BRAKES port g in the seat, and through this to the chamber D above theequahzing piston in the lower part of the brake valve. Chamber D is connected through port s and pipe connections^as shown, to the qualizing reservoir. The purpose of the equalizing reservoir is to furnish a volumeto chamber D above the equalizing piston larger than could bepermissible within the brake valve proper. From the equalizing-reservoir p
