器用フューエルポンプの構造。A fuel pump housing includes a variable volume chamber, a fuel inflow chamber, and a fuel outflow chamber that are separated from each other by a partition wall, and a partition wall separating the variable volume chamber and the fuel inflow chamber from the fuel inflow chamber. A first check valve that allows flow only toward the variable volume chamber is provided, and a first check valve that allows flow only from the variable volume chamber to the fuel outflow chamber is provided on a partition wall separating the variable volume chamber and the fuel outflow chamber. In this fuel pump, a fuel pump is provided with two check valves, and a fuel inlet chamber is connected to a fuel tank, and a fuel outlet chamber is connected to a carburetor float chamber. The structure of a fuel pump for a carburetor is provided with a third check valve that allows fuel to flow only from an outflow chamber to an inflow chamber.
