負圧コツク。 A combustion diaphragm 2, a pressure receiving diaphragm 3, and a correction diaphragm 4 are arranged in the fuel diaphragm 1, and a fuel inlet 6 and a fuel outlet 7 are opened in a fuel chamber 5 partitioned by the fuel diaphragm 2. An atmospheric release hole 9 is opened in the atmospheric chamber 8 formed by the pressure receiving diaphragm 3 and a negative pressure introduction hole 14 is opened in the pressure receiving chamber 13 formed by the pressure receiving diaphragm 3 and the correction diaphragm 4. A correction passage 14 communicating with the fuel chamber 5 is opened in the correction chamber 16 formed as a result, and an on-off valve 15 arranged opposite to the fuel outlet 7 is integrated with the fuel diaphragm 2, the pressure receiving diaphragm 3, and the correction diaphragm 4. At the same time, the effective pressure receiving diameter of the pressure receiving diaphragm 3 is made larger than the effective pressure receiving diameter of the fuel diaphragm 2 and the correction diaphragm 4, and the effective pressure receiving diameter of the correction diaphragm 4 is set to be the same diameter or larger than the effective pressure receiving diameter of the fuel diaphragm 2. Negative pressure.
