So how exactly does a governor work? The 'black box' still holds many mysteries for some. Here it is in a nutshell based on the well-known UG8 model.
The needle valve controls the flow of oil between the compensation piston and the oil sump.
The compensation piston is used as temporary feedback to the pilot valve, which stabilises the system during the speed transient.
Provides oil pressure for the governor.
The function of the accumulator pistons and springs are to provide and store oil pressure for operation.
The purpose of the power piston and link is to rotate the governor output shaft to either increase or decrease fuel position.
The purpose of the ballhead is to sense changes in actual speed as compared to the speed setpoint applied by the speeder spring.
The purpose of the speeder spring is to change the speed setpoint.
The ouput shaft provides output connection from the governor to the fuel control of the prime mover.
Facilitates the maintenance of oil quality and quantity.
The drive shaft is rotated by the prime mover.
