PURPOSE: To provide an inexpensive fuel pressure control valve where the variance in adjusting the pressure is small, and the number of parts and manhour is small. CONSTITUTION: A housing H Is demarcated to a spring chamber 4 and a fuel chamber 3 by a diaphragm F. On the diaphragm F, nitrile rubber is arranged on one side of the base cloth F3 and the fluoro-rubber is arranged on the other side of the base cloth F3, and the nitrile rubber is synthesized to be integrated with the fluoro-rubber through the base cloth F3. A first retainer 9 is arranged on one side of the diaphragm F, and a second retainer 10 is arranged on the other hand of the diaphragm F. The first retainer 9 and the second retainer 10 elastically hold the diaphragm F by a spring 12 which is shorten in the spring chamber 4 and a all valve spring 11 to press a ball valve 8. |
