装置。A negative pressure chamber and a fuel chamber are defined by a diaphragm, and the negative pressure chamber of the main body is communicated with an intake pipe, the fuel chamber is communicated with a fuel supply passage of a fuel injection valve, and a valve seal of a fuel return pipe is communicated with a fuel tank. shape, form, by protruding into the fuel chamber,
In a fuel pressure regulating device in which a valve element that opens and closes the valve seat is attached to a guide, the valve element is moved in the forward and backward direction of the diaphragm by interposing a spring that biases the valve seat on which the valve element is seated in the direction of the diaphragm. while providing a solenoid to hold the valve seat in place against a spring, with means for demagnetizing the solenoid when the fuel temperature or associated temperature rises above a predetermined value. Features: Fuel pressure regulator for internal combustion engines.
