PROBLEM TO BE SOLVED: To provide a venturi-system pilot type governor device with high stability.SOLUTION: In a venturi-system pilot type governor device, a pilot flow passage 12 is provided with a venturi 12 V through which a constriction part 12 V1 communicates with a driving part 11A for a main governor 11, a pilot governor 13 which controls the flow rate of the pilot flow passage 12 on the basis of secondary pressure is provided, and capacity Vof a communication part between the venturi 12 V and pilot governor 13 is so set that control pressure becomes stable against load variation in primary pressure. |
