Abstract

A combined float bowl carburetor and fuel pump for small engines has a lateral extension on its carburetor body that terminates at a flat exterior surface to which open certain cavities and a passageway leading to the float valve inlet. A block-like pump body having flat inner and outer surfaces overlies said exterior surface and has cavities opening to its inner surface that cooperate with those in the carburetor body. A resilient pump membrane, providing a pump diaphragm and valves, is confined between the pump body and said exterior surface. Two cavities open to the outer face of the pump body, which is overlain by an imperforate resilient membrane to define inlet and outlet surge chambers that are respectively communicated with the pump by way of the inlet and outlet valves. All cavities, inlets and outlets are arranged to ensure maintenance of a consistent head of fuel at every inlet.
