ヤフラム式気化器。[Scope of Claim for Utility Model Registration] A recess provided on one side of the carburetor body through which the intake passage passes is closed with a cover having a recess through a diaphragm, and the recess on one side of the diaphragm and the recess on the carburetor body A regulated chamber in which a nozzle hole connected to the intake passage opens, and an atmospheric chamber connected to the atmosphere by the other side of the diaphragm and the recessed part of the cover,
Furthermore, a diaphragm type valve is arranged corresponding to a valve seat provided in a fuel passage connected to the regulation chamber, and is rotatably supported around the valve, and the opening and closing are controlled by an arm that operates according to the chamber pressure in the regulation chamber. In a multiple diaphragm type carburetor in which a plurality of carburetors are arranged, a fuel pump is disposed in a first fuel inflow path that communicates a first fuel passage of the first diaphragm type carburetor with a fuel source, and A first fuel return passage branched from the first fuel passage is connected to a second fuel passage of the second diaphragm carburetor, and a second fuel return passage branched from the second fuel passage is connected to a third diaphragm carburetor. A multiple diaphragm type carburetor comprising a third fuel return passage connected to a third fuel passage of the type carburetor and branched from the third fuel passage to a fuel source.
