Plate io8 is a longitudinal side section of the brake valve(running position), showing the main slide valve EV 312 andhow the graduating valve EV 317 is controlled by piston EV 311and lever EV 302; also port O in the back cap, closed by the ventvalve EV 180. This view also shows the different positions ofthe brake valve handle. Plate 109 is a cross section through the. EV3Cf7 Eveo EVI58 JCOPPER PIPETO ACCELERATORRESERVOIR PLATE 108. valve (rear view). Plate 110 is a cross section through themain slide valve EV 312. This view shows the main reservoirand brake pipe connections; it also shows the location of passageH, which connects the supplementary reservoir and chamber D^back of piston EV 311 ; also port O drilled to the slide valve seat,and cavity R in the slide valve.
