Engine: Motor Plants and Auxiliary Boilers

1. A With the speeder spring compression force and the flyweight centrifugal force in equilibrium, the flyweights are pivoted inward and the pilot valve plunger will be in the raised position aligning the control port to the pressure port.
2. B With the speeder spring compression force and the flyweight centrifugal force in equilibrium, the flyweights are pivoted to vertical, and the pilot valve plunger can be positioned in any position.
3. C With the speeder spring compression force and the flyweight centrifugal force in equilibrium, the flyweights are pivoted outward and the pilot valve plunger will be in the lowered position aligning the control port to the drain port.
4. D With the speeder spring compression force and the flyweight centrifugal force in equilibrium, the flyweights are pivoted to vertical, and the pilot valve plunger will be in the centered position blocking off the control port.
