Gas governor

A gas governor comprising,

• a casing that has a primary pressure chamber, a secondary pressure chamber above or below the primary chamber, and a valve seat which is disposed between the primary pressure chamber and the second pressure chamber;
• a diaphragm that faces to the primary pressure chamber at an opposite side of the valve seat;
• and
• a governor valve that has a valve body part with a diameter which is enlarged in sequence toward an end part at a side of the secondary pressure chamber,
• wherein a first axis part of the governor valve, which extends from the valve body part to a side of the diaphragm, is connected to the diaphragm, and by displacing the governor valve through the diaphragm depending on gas pressure fluctuation in the primary pressure chamber, gas pressure fluctuation in the secondary pressure chamber is suppressed and
• wherein the gas governor further comprises a cylindrical weight that is inserted with a clearance around an outside of a second axis part of the governor valve, which extends from the valve body part to an opposite side of the diaphragm, or the first axis part, and is movable freely in an axial direction, and an annular seat surface on which the cylindrical weight is able to be seated by self-weight,
• wherein:
• a projecting part(s) is provided with only a part in a circumferential direction of one of the annular seat surface and a lower end surface of the cylindrical weight, and by contact of the projecting part(s) with the other of the annular seat surface and the lower end surface of the cylindrical weight, the cylindrical weight is supported on the annular seat surface in an inclined state from an upright posture.
