isthe negative value of s to cut off at crank-position 0P\ or at Ol of thestroke of the piston. The vaiious values of s are brought down on to one line, LF, andthese distances may be used for graduating the scale by which thevalve may be set for any desired point of cut-off. Reuleaux Diagram for… … Fig, 05. Thus, taking the same example as in Fig. 94, draw the main-valve circle with radius OM, equal to the eccentricity of the main-valve eccentric. Draw also the relative-motion circle with radiusOD of the relative motion or virtual eccentric (obtained as explainedin Fig. 92), and from the same…
