Wlith certain types of valve gear, as will be see" later, to prevent excessive compre$si0n large elearance is "acessary. 35. DRAWING HYPERBOLIC EXPANSION LINES. First Method. Start with the X and Y axes, Fig. 38, and using absolute pressures and volumes as co-ordinates, locate the point of cutoff, c, and draw the vertical line cc'. Through any point 1 in the line cp produced, draw Ol from the origin, to intersect ed at 2. Then the vertical and horizontal lines drawn respectively through 1 and 2, intersect at 3, which is a point on the expansion curve. Other points may be found in the same manner. Starting at k, the beginning of compression, draw the vertical line kk'. Through any point, 4, on this line, draw 04 from the origin to intersect the back pressure line kb at 5. Then the horizontal and vertical lines drawn respectively through 4 and 5, intersect at 6, which is a point on the compression line. The pressure at the end of compression _is found by first determining the point of intersection 7 between O0 and kl;/, and then from this point drawing horizontally to intersect the clearance line at 8. Second Method. To construct a hyperbola through the point b, Fig. 39, draw any line through this point to intersect the axes at a and a'. Along this line from a lay off a distance equal to ab, locating the point b', which is a point on the hyperbola. 36. CUSHIONING THE RECIPROCATING PARTS. First suppose there is no compression. Then when the pist011 9-pproaches the end of its stroke the effective steam pressure and the inertia of the reciprocating part are both acting towards that end of the stroke, ...
