Claims

[Scope of utility model registration request]

a housing, a diaphragm that divides the inside of the housing into a fuel chamber to which pressurized fuel is supplied and a negative pressure chamber to which suction negative pressure is introduced; an elastic member that biases the diaphragm toward the fuel chamber; and a fuel chamber in the fuel chamber. The engine is characterized by comprising an outlet passage for discharging fuel, a valve body attached to the diaphragm and capable of opening and closing the outlet passage, and a biasing means for biasing the diaphragm toward the fuel chamber to pressurize the fuel when the engine is stopped. pressure regulator.
