present graphically the relative and actual velocities of travelof the piston and of the valve. Divide the path of the crank-pinABC into any number of equal parts and, by the use of theconnecting-rod, find the corresponding piston positions. At thepoints so found, lay off an ordinate that… … Fig. 78. If any such exist, as in the Corliss engine, the actual position mustbe plotted graphically. (Fig. 78.)Lay off 54 = outside lap; 43 = steam lead; 41 = the maximum port opening; 12 = the overtravel; 24 = exhaust-port; 56 = the inside lap; 67 = the exhaust-port opening; 78 = exhaust…
