を制御する。 A flame detection device is used to cut off the gas supply to the main burner of a gas appliance, such as an instantaneous gas water heater, when the starter flame goes out.
It operates based on several known and widely applied principles, as disclosed in Japanese Patent Publication No. 61-10731, for example. Among these flame detection devices, there are devices that guarantee safety and also guarantee the safety of the means to directly control the value of the intensity of the fire. Such existing devices, as is well known, consist of a membranous capsule formed by a sealed envelope or valve located within the flame to be examined and filled with air. This capsule is connected via a capillary tube to another capsule surrounded by a small inflatable membrane that can be expanded by the expansion of air in the valve, controlling the amount of gas introduced into the main burner.

室内に位置している。 Although this known device has some advantages, it requires mechanical energy when used as the primary gas intake control means, so it is difficult to use gases, especially as described in the applicant's French Patent No. 1366039 and its Preferably, it is used upstream of the main control valve as a means of controlling and regulating instantaneous water heaters that operate without a permanent spark, such as those described in Supplementary Patents No. 96318 and No. 77-32668. . In these known devices, the membrane of the membrane capsule, which acts on the microvalve for introducing gas into the pilot flame, is located in the gas intake chamber.

るガスの圧力より大きくなるためと思われる。 However, it has been found that such known devices fail after a certain period of operation. That is, the membrane of the membranous capsule may remain in an expanded state even when the valve cools (although normally the membrane of the membranous capsule contracts when the valve cools). (The valve does not close again at the time of failure), making it impossible to extinguish the spark under certain conditions, making it impossible to achieve the intended purpose. The reason why the valve does not close again is that the pressurized gas diffuses through the membrane and enters the capsule, where this gas pressure adds to the previously existing air pressure and increases the gas pressure on the other side of the membrane. This seems to be because the pressure is greater than that of the

る。 The control and safety device for instantaneous gas water heaters etc. according to the invention uses an air-containing valve located in the pilot flame and communicating via a capillary to the membrane that transmits the motion to the valve regulating the supply of gas to the high pressure chamber. Ori,
The movement of the membrane is transmitted to the first push rod to move the first push rod downward, and the downward movement of the first push rod causes the lever to swing about the pivot to raise the second push rod. The rising movement of the second push rod is the third
The movement is transmitted to the push rod to open the aforementioned valve, and the transmission of the motion from the second push rod to the third push rod causes a second membrane to shut off the gas in the high pressure chamber from outside air. This effectively prevents malfunctions of the air-containing valve.

This small case 10 is attached to an extension of a support plate 12 fixed to the case 1 with a set of screws 13. Inside the small case 10 is a push rod 1 that engages with the back side of the membrane 9.
6 is located, and this push rod is slidably mounted in a guide hole 26 provided in the case 10, and the free end of the push rod 16 protrudes from the case 10 and abuts on the adjustment screw 21. This adjustment screw is carried on one end of a swing lever 22 which is pivotally mounted on a pivot 23 fixed to the support plate 12. The other end of the rocking lever 22 engages a second pusher or push rod 24 which is connected to a guide ring held in place by a support plate 12 at the bottom of the bore 11 in the case 1. It is slidably mounted within 25 with a small clearance. The upper end of the second push rod 24 engages the underside of a small membrane 17 clamped within the bore 11 by an annular seal 18 . This second membrane 17 is connected to the duct 6
and the bore 11, thereby completely blocking communication between the gas in the high pressure chamber 4, the air in the bore 11, and the outside air. Furthermore, a third pusher or push rod 19 located in contact with the surface (upper surface) of the second membrane 17 is held in place within the guide ring 20, and the upper end of this third push rod 19 is connected to the microvalve 7.

For this reason,
The swinging lever 22 swings around the pivot 23 and raises the second push rod 24. As a result, the second membrane 17 and the third push rod 19 also move upwards, opening the microvalve 7. The role of the second membrane 17 is to transmit the movement of the second push rod 24 to the third push rod 19, and at the same time completely prevent the gas in the high pressure chamber 4 and the bore 11 from entering the capsule.
