In these figures certain parts are referred to by the useof abbreviations as follows: (brake pipe); (supplementaryreservoir); (brake cylinder); (auxiliary reservoir); (safety valve); EX. (exhaust). and Charfjing The valve is illustrated inrelease and charging position in Fig. 01. 80 AIR BRAKES Air from the brake pipe enters through the passages a, e, g,and h, to the face of the triple-valve piston, forcing it to releaseposition, thence through feed groove i to chamber R and the aux-iliary reservoir. Brake-pipe air in passage a also raises the checkvalve 15, and entering chamber Y flows thence through the ports. Fig. 61. Type L Triple Valve, Showing Release and Charging PositionCourtesy of Westinghouse Air Brake Company, Wilmerding, Pennsylvania y and j into chamber R and the auxiliary reservoir. This checkvalve then prevents any back flow of air from the auxiliary reservoirto the brake pipe. At the same time, port h registers with port x,and the air in chamber R also flows through these ports and xand x into the supplementary reservoir. Both the auxiliary andsupplementary reservoirs are thus charged at the same time and AIR BRAKES 81 to the same pressure from the brake pipe through the two differentchannels already mentioned. With the parts in the above-mentioned position, air from thebrake cylinder, entering the triple valve at C\ flows through passager, port 71, large cavity lo in the graduating valve, and ports vi andp to the atmosphere, thus releasing t
