レート装置。[Claims for Utility Model Registration] 1. A fuel pressure regulating device for a fuel injection internal combustion engine, comprising a regulator body and a solenoid valve interlocked with the regulator body, wherein the regulator body is connected to a fuel chamber and back pressure by a diaphragm. A fuel supply pipe and a return fuel passage are connected to the fuel chamber, and the diaphragm is displaced by a pressure difference between the fuel chamber and the back pressure chamber, and the diaphragm has a back pressure. A valve body is attached which discharges excess fuel from the fuel chamber connected to the fuel supply pipe 5 into the return fuel passage by displacement toward the chamber side, and the back pressure chamber and the return fuel passage are connected by a return pipe having a jet. Also, the back pressure chamber and the fuel supply pipe are communicated via a bypass pipe, and the solenoid valve is installed in the bypass pipe, and the solenoid valve is connected to the back pressure chamber from the fuel supply pipe by a signal from a control device. A fuel pressure regulating device characterized by intermittent supply of fuel. 2. The fuel pressure regulating device according to claim 1, wherein the solenoid valve is operated while monitoring a detected value of a fuel pressure sensor disposed in the fuel supply pipe.
