とを特徴とする燃料圧力制御弁装置。 A case that constitutes a fuel chamber and a pressure chamber, a fuel inlet and a fuel outlet opened on the fuel chamber side of the case, a pressure inlet opened on the pressure chamber side of the case, a fuel chamber and a pressure chamber. A diaphragm stretched between the chamber and the case so as to divide the inside of the case into two chambers, an armature supported by the diaphragm and inserted into the fuel chamber, and a spring member that biases the armature toward the fuel chamber. , a pole is provided at the fuel outlet of the case to form a fuel passage that guides the fuel in the fuel chamber to the fuel outlet, and the pole is arranged between the pole and the armature, and as the armature moves, the fuel in the pole is A fuel pressure control valve device comprising a sphere that opens and closes a passage,
The fuel passage of the pole is formed to have a diameter smaller than that of a sphere guide fuel passage which is slightly larger than the diameter of the sphere so that the sphere can slide, and It includes a valve seat formed to prevent the outflow of fuel by coming into contact with the sphere, and a fuel discharge passage opened to guide the fuel from the valve seat to the fuel discharge port of the case. The sphere is slidably inserted into the sphere guide fuel passage, and the fuel discharge passage is provided with an elastic member that applies a biasing force to the sphere to keep the sphere and the armature in constant contact. A fuel pressure control valve device characterized by:
