化器。[Scope of Claim for Utility Model Registration] A pressure regulating device partitioned into an atmospheric pressure chamber and a fuel chamber by a diaphragm, a main passage communicating the fuel chamber with a main nozzle that opens into a vent lily of a carburetor, and the fuel chamber. A fuel passage having a needle valve opened and closed by the operation of the diaphragm is opened in the chamber, and a fuel introduction passage is provided from the fuel tank to the fuel passage via a fuel introduction pipe. A membrane vaporizer comprising a manual priming pump that processes fuel and introduces it into the fuel introduction passage, the fuel introduction passage having a first branch passage and a second branch passage; The branch path is a passage leading to the fuel chamber, and a valve device is provided that operates at a pressure lower than the pressure that acts to open the needle valve, and the second branch path is connected to the pressure of the diaphragm valve device. The diaphragm valve is provided with a valve stem that operates based on the differential pressure between the fuel pressure acting on the pressure chamber and atmospheric pressure, and the valve stem opens and closes the main passage. A membrane carburetor comprising: an overflow pipe connecting the fuel chamber and the fuel tank.
