Cyclopedia of locomotive engineering, with examination questions and answers; a practical manual on the construction care and management of modern locomotives . to Fig. 239 that both sets ofpistons are at the lower end of the stroke. JTheboiler connection is clearly shown to the left. Thedotted lines crossing each other indicate steam should be remembered that the reversing valve thatcontrols the admission of steam to the right-handcylinder is located under the left cylinder and viceversa. Both slide valves are in their bottom positions in thecut, Fig. 239, and as steam enters the valve chamberunder the left-hand piston, it passes on through portg to the valve chamber under the. right-hand piston,and live steam also passes through the pert marked bto the under side of the right-hand piston, and at thesame time passes up through the port c to the topside of the left-hand piston. The steam pressureaccumulated under the right-hand, or low-pressurepiston, forces it up as shown in Fig. 240. Just as thispiston reaches the end of its up stroke, the reversingrod plate engages the button on the end of the reversing 576 LOCOMOTIVE ENGINEERING. 1 FIPE FROM EOl 2 DP 552 DP 192 DP 15 DRAIN COCK Figure 240 New York Duplex Air Pump,upstroke, low-pressure piston 2 DP 57,2 DP 5^2 DP 591 DP 7 2CPA AUTOMATIC AIR BRAKES 57
