The importantfeature of the governor nozzle is a cone-shaped piston at thelower end of the valve rod passing through the stuffing-box andconnected to the eccentrics as shown in Fig. 175. A cone-shapedjet flows continuously over this cone. The central chamber ofthe governor nozzle as well as the spaces around it except a narrowannular passage communicating with a similar passage shownby a circular section in Fig. 176 at the left-hand side of the.
