The end face of the valve housing 101 and the lid body 107 that are open
A diaphragm 108 having a valve body for opening and closing the opening of the fuel outflow passage 103 is disposed between the lid body 107 and the diaphragm 108, and the valve body opens and closes the opening of the fuel outflow passage 103. A coil spring 112 is disposed to bias the diaphragm 108 in the direction of closing the valve chamber 108, and when the fuel pressure in the fuel system led to the valve chamber 102 exceeds a specific pressure, the valve body closes the fuel outflow passage 103.
In the fuel pressure regulator that maintains the pressure of the fuel system constant by letting the fuel flow out from the opening of the diaphragm 10, the valve body is connected to the diaphragm 10.
a fixed valve seat 104 formed around the periphery of the fuel outflow passage opening;
A fuel pressure regulator having a valve seat formed by disposing a valve seat body 105 which is slidable upward and has a valve opening having a diameter smaller than that of the fuel outflow passage 103.
