In this valve, the diaphragm 3 is biased toward the atmospheric chamber A 2 by a support spring 5, and the outlet 6 at the center of the lower case 2 is opened and closed by the valve element 3a. The surface of the peripheral edge part 3b of the diaphragm is formed into a wedge shape by slanting outwardly, and the inclined surface of the peripheral edge part 3b of the diaphragm is attached to both or one of the peripheral flange parts 1b and 2b of the upper and lower cases 1 and 2. The peripheral flange portions 1b, 2b are formed with substantially coincident inclined inner surfaces.
The peripheral edge 3b of the diaphragm 3 is interposed between the
A steam fuel control valve for an engine, which is constructed by tightening a diaphragm peripheral portion 3b with a clip 7.
