Here the arc has no effect uponthe movement of the valve, its motion being derived from thelever action of the eccentric rod, as was explained in a previousl)aragraph. The path of the front end of the eccentric rod (andthe lower end of the transmission yoke^ C, is, therefore, theresultant of the movement of the back end of the eccentric rodin a circle, and the fulcrum B, in an arc whose radius is path traced by the point, C, takes the well known ellipticalform. Motion is transmitted from this point to the horizontalarm of the lull crank, GFII, through the transmission yoke, v
