The governor operates to revolve the cut-offeccentric on its shaft. On this particular engine, there isan auxiliary governor spring controlled by a sliding collar Fig. 38 shows also the form of piston adopted for thelarge cylinder of this engine. There is a single centralpacking riug which is gripped by making the piston in twotransverse halves clamped together by the central nut onthe piston rod. The loosening of this nut is prevented bya clamp ring thereon lying in a circular recess and held bya screw. 3EP1. Ut*S
