Such adjust-ment determines the speed at which the centrifugal force over-comes the spring and forces the pin outward to engage with atrigger cam L. This cam is rigidly attached to one end of a shortshaft S, which carries at its other end a trigger H. A small plateat the bottom of the valve lever C is supported normally at oneend on the trigger H and at the other end on a screw providedfor adjusting the spring on the auxiliary steam valve E. 222 THE STEAM TURBINE If the speed of the turbine should become higher than the limitfor which the weight sp
