At a we , etc., or b and between a and a', c and have the L-piston at midstroke, while b', d and d', etc., indicate shifting of the volume in the receiver and connec-- action from end to end. Thus, when the Y exhaust is… … volume is raised from Y' + ^to V'+^-2 + VlS or from C to D;. For the simultaneous positions, a, we see that the L-piston is at midstroke, _ A while the H-piston is exhausting.
