器の始動燃料供給装置。 A constant pressure chamber formed by a diaphragm for directing fuel from a fuel pump that operates with the operation of an internal combustion engine to a fuel injection hole at a constant pressure, and a negative pressure acting on the constant pressure chamber to control the fuel pump. In a diaphragm type carburetor equipped with a fuel valve operated in association with the diaphragm to interrupt communication with the constant pressure chamber, the fuel valve is connected in the middle of a fuel supply passage from the fuel tank to the fuel valve of the carburetor. a first fuel storage chamber connected to the intake passage of the carburetor;
A fuel storage chamber is provided, and the first fuel storage chamber and the second fuel storage chamber are connected at their lower portions by a communication passage, and the first fuel storage chamber is connected to the other end of the fuel storage chamber and is driven in conjunction with the starter of the engine. A suction pump is connected to the fuel tank, and the fuel supply passage and the first
A normally closed check valve that opens due to the negative pressure generated when the intake pump is operated is provided in a passage communicating with the fuel retention chamber, and an air passage is provided in the first fuel retention chamber and an air bleed passage is provided in the second fuel retention chamber. and a normally open check valve that closes when the suction pump is operated is disposed in a communication path between the first fuel storage chamber and the second fuel storage chamber and an air path connected to the first fuel storage chamber. A starting fuel supply device for a diaphragm type carburetor, characterized by the following.
