<P>PROBLEM TO BE SOLVED: To provide a gas governor having a pilot governor, which prevents the occurrence of an offset, and which facilitates adjusting an increase of response sensitivity within a range not causing vibration. <P>SOLUTION: This gas governor including the pilot governor 5 for opening and closing a governor body 1 corresponding to a secondary pressure P<SB POS="POST">2</SB>of a gas to keep the secondary pressure P<SB POS="POST">2</SB>constant, reducing a pressure of a gas conveyed by a primary pressure P<SB POS="POST">1</SB>from an upstream side to the secondary pressure P<SB POS="POST">2</SB>, and allowing the gas to flow to a downstream side, a secondary-side orifice 8 is disposed in a pipe conduit 3 at the downstream of the governor body 1, an auxiliary diaphragm pressure chamber 10 is disposed in the pilot governor 5 for making a pressure P<SB POS="POST">3</SB>of the gas of which a pressure is reduced at the secondary-side orifice 8 part, act to assist the force for opening and closing a pilot valve 28 of the pilot governor 5 with the secondary pressure P<SB POS="POST">2</SB>at the downstream while being opposed to a pilot spring 13 of the pilot governor 5, and further a throttle 11 and a tank 12 are disposed in a pipe conduit 9 connecting the auxiliary diaphragm pressure chamber 10 and the secondary-side orifice 8. <P>COPYRIGHT: (C)2012,JPO&INPIT |
