5, a cylindrical body 32 into which the shank 31 is vertically inserted, and a compression spring 33 compressed between the upper protrusion 31a of the shank 31 and the inner bottom of the cylindrical body 32. , the spring 33
The lower end of the cylinder body 32 presses against the valve seat 34 due to the elasticity of
The regulating valve 14 itself is attached to the mouth of the gas passage 12 on the pressure regulating chamber 13 side by a threaded portion 37.

で共通の符号を付し、説明は省略する。FIG. 4 shows an embodiment using a regulating valve 38 having a structure different from that described above. This regulating valve 38 has an inverted T-shaped cross section, one of which has the protrusion 15 similar to the above, and the other has a flange 3.
9, the protrusion 15 is located on the adjustment chamber 13 side, and the flanged portion 39 is located on the gas inlet ll side, and in the gas passage 12 expanded from the middle, there is a gap between the flanged portion 39 and the tied end 12a. Pressure is applied in the direction of the adjustment chamber 13 by a compression spring 40 compressed in the flange, and the adjustment member 16 in contact with the protrusion 15 pushes against the compression spring 40, and the valve seat 41 provided in the flange-shaped portion 39 and the sliding A predetermined gap S is formed between the adjustment valve 38 and the edge 42a of the removal prevention member 42 attached to the other end of the moving chamber. Since the other configurations may be the same as those in FIG. 1, the same reference numerals are given and the explanation will be omitted.

示す。In each figure, 50 is a yoke equipped with a magnet 52 that magnetically attracts the flange 51 of the gas cylinder 1, and 53 is a positioning projection that engages with the notch 54 of the flange 51, and these constitute a gas cylinder holding device 55. Further, the yoke 50 is made of a material that loses its magnetic force when the set temperature is reached, and serves as a safety device in the event of an abnormality. 56 indicates a feed pipe connected to the gas outlet 21.

ガスボンベ１を受口部材３に接続し、操作ハンドル３０
を操作することにより行なう。(Operation) To operate the governor constructed as described above, first connect the gas cylinder 1 to the socket member 3, and then
This is done by operating.

力調整室１３、ガス出口２１、送給管５６を経て燃焼部
に達する。Due to the connection, the cylinder 1 is held on the socket member 3 by the holding device 55, the valve nozzle 2 is opened, and gas is discharged. Gas flows into the governor body 10 from the gas port 11 and reaches the regulating valve 14.38 provided in the gas passage 12. When the regulating valves 14 and 38 are open, the gas reaches the combustion section from each gap S through the pressure regulating chamber 13, the gas outlet 21, and the feed pipe 56.
調整弁１４．３８の開閉は操作ハンドル３０によって行
なわれ、また開度の調整は隙間Ｓにより決まる。The regulating valve 14.38 is opened and closed by the operating handle 30, and the opening degree is determined by the gap S.
即ちカム板２７がそのカム面２６の最深部ａで係合軸２
５と係合している閉状態から、カム面最浅部す方向へ回

に隙間Ｓを生じ、更にハンドルを操作すると隙間も増加
し、ガス量を増大させる。故に隙間Ｓの制御によりガス
量を微妙に調整することができる。That is, the cam plate 27 touches the engagement shaft 2 at the deepest part a of the cam surface 26.
When the handle 30 is rotated from the closed state in which it is engaged with the protrusion 15 in the direction toward the shallowest part of the cam surface, the cam plate 27 moves toward the diaphragm and the protrusion 15
, the regulating valve 14.38 creates a gap S between it and the valve seat 34.41, and when the handle is further operated, the gap also increases, increasing the amount of gas. Therefore, by controlling the gap S, the gas amount can be finely adjusted.
この間ダイヤフラム１７はガス流の圧力による作用下に

されて送られる。During this time, the diaphragm 17 is under the action of the pressure of the gas flow, and as the pressure increases, the pressure adjustment chamber 13 expands, and the protrusion 15 also moves toward the pressure adjustment chamber 13, reducing the gap S, and the pressure decreases. Then, on the contrary, the gap S is made wider. Therefore, even if the gas pressure fluctuates, the pressure is properly regulated and sent to the combustion section.

外れることとなる。To close the regulating valve 14.38, the operating handle 30 is turned in the opposite direction. Then, the cam plate 27 also moves away from the diaphragm 17, so the gap S becomes small (
and finally closes completely. Also, during use, if the temperature rises above the set value, the magnetic force of the yoke 50 will be lost.
The gas cylinder 1 is no longer held by the magnetic force and comes off from the socket member 3.

全体の小型、軽量化にも寄与する。(Effects) The present invention is configured as described above, and the gas discharged from the gas cylinder is supplied to the pressure adjustment chamber through the adjustment valve,
Since the adjustment valve can be opened and closed and the opening degree can be adjusted using the on/off knob, there is no need for a separate device stopper like in the past.Furthermore, the opening degree can be adjusted by adjusting the size of the gap, so there is no sudden rise, and fine adjustments can be made. Since the gas is sent to the gas outlet after being pressure regulated by the diaphragm, it is sent to the combustion section etc. at a stable pressure, and there is no lever-type valve member like conventional governors. The pressure adjustment effect also becomes smoother. In addition, since the regulating valve is extremely small and no appliance plug is required, the structure of the governor is also extremely simple and compact, contributing to the reduction in size and weight of the entire gas appliance.

Contents of amendment Contents of amendment (1) The following sentence is added between lines 4 and 5 on page 14 of the specification. "In conventional covers, the pressure of the gas that passes through the governor and is regulated (the discharge pressure at the gas inlet is called the primary pressure, while the adjusted pressure is called the secondary pressure) is determined and fixed at the production stage. Therefore, if the hole diameter of the nozzle is determined when used in a gas appliance, the maximum throughput, that is, the upper limit of the amount of gas (thermal power) supplied to the combustion section is determined.
The secondary pressure can be set to any desired pressure by rotating the knob, and the secondary pressure can be maintained. In other words, by rotating the knob, the amount of gas supplied to the combustion section can be expanded from a small amount to a large amount (see Figure 8) compared to conventional systems. This means that the fire power can be controlled very smoothly, from medium heat to simmering heat, or to simmering heat. Therefore, the present invention provides a highly convenient governor."
