供給装置。In an internal combustion engine equipped with a carburetor and a supercharger having a primary throttle valve and a secondary throttle valve, a diaphragm actuator that opens and closes the secondary throttle valve is provided, and the diaphragm chamber of the diaphragm actuator is connected to the diaphragm chamber of the diaphragm actuator through a connecting passage. and communicates with a pressure control valve, and connects the connecting passage to the intake system passage of the engine via a throttle, and the pressure control valve is operated when the intake pressure in the intake system passage acting on the valve becomes higher than a set value. - supplying atmospheric air to the diaphragm chamber of the diaphragm actuator through the connection passage when the downstream throttle valve is closed, and the diaphragm actuator immediately closes the secondary throttle valve when atmospheric air is supplied to the diaphragm chamber; The fuel supply device is characterized in that the primary throttle valve opens due to engine acceleration and the secondary throttle valve gradually opens when intake air is supplied to the diaphragm chamber through the throttle.
