[Problem(s)] To provide a governor capable of preventing damage to parts when the pressure in the primary side channel rapidly rises, and of alleviating pressure fluctuation in the secondary side channel. [Solution] A governor 1 is provided with a non-return valve 19 at a shield plate 16 such that when the pressure in the primary side channel 2 rapidly rises, the fluid from the primary side channel 2, which has passed through the port 4, can immediately flow into the pressure detection chamber 13 through the non-return valve 19. As a result, when the pressure in the primary side channel 2 rapidly rises, the governor 1 is capable of entering a closed valve state within a short amount of time. |
