来る様になっていた。FIG. 3 is a cutaway side view showing one embodiment of a conventional gas pressure regulator. A valve port 3 is provided in the middle of a gas passage having a gas port 1 at one end and a gas outlet 2 at the other end. The valve port is made of die-cast aluminum or the like that constitutes the main body of the gas pressure regulator. Also, a diaphragm 7 that is constantly biased by a spring 6 is set in the gas inflow passage 4 through the valve port 3, and this diaphragm 7 opens an air chamber 9 that communicates with the atmosphere through a vent hole 8. At the same time as forming the sections, the valve port 3 was provided with an adjustment valve 10 that changed the degree of opening of the valve port 3 in conjunction with the diaphragm 7 . The regulating valve 1o was a resin molded product or a metal-cut product made of aluminum or the like, and was an inelastic body. Further, the spring 6 that biases the diaphragm 7 can be adjusted by an adjustment screw 11, and the diaphragm 7 can be stably biased by a spring holder 12.

きい傾向があ−２だ。Problems to be Solved by the Invention However, in the case of a gas pressure regulator having such a configuration, the variation in volumetric rate on the gas inflow passage side, that is, on the secondary gas pressure side, is caused by the above-mentioned air chamber 9 and vent hole 8. However, since there is no structure that can reduce the volume fluctuation rate variation on the gas outflow passage side, that is, on the secondary gas pressure side, it is called the so-called governor 0C. Abnormal vibration noise may occur when the regulating valve 10 and valve 13 come into contact with each other due to the vibration of the regulating valve 1o, especially as the pressure difference between the secondary gas pressure side and the secondary gas pressure side increases. The tendency is -2.

FIG. 1 is a cutaway side view showing one embodiment of the present invention. A valve port 15 is provided in the middle of a gas passage having a gas port 13 at one end and a gas outlet 14 at the other end. The valve port 15 is composed of a valve port structure 17 whose shape is coated with an elastic body 16 such as rubber. Also, valve port 15
The gas inflow passage 18 and the gas outflow passage 19 are formed through the gas inflow passage 18 and the spring 2
A diaphragm 21 is provided which is constantly energized by the diaphragm 21, and this diaphragm 21 defines an air chamber 23 that communicates with the atmosphere through a vent hole 22. At the same time, a valve is inserted into the valve port 15 in conjunction with the diaphragm Opening of mouth 16 1]
A regulating valve 24 for changing the degree is provided. Further, the force of the spring 20 that biases the diaphragm 21 can be adjusted by an adjustment screw 25, and the diaphragm 21 is always biased in a stable state by a spring holder 26.
