Patent number: 12123374Abstract: A fuel supply device includes a main body, fuel chamber, fuel supply pipe and a fuel valve. The main body has a main bore with an inlet for air and an outlet through which a fuel and air mixture flows. The fuel chamber retains a supply of fuel. The fuel supply pipe has a passage communicating with the main bore and through which fuel from the fuel chamber flows to the main bore. And the fuel valve has a valve seat, a valve element movable relative to the valve seat between an open position and a closed position, an inlet upstream of the valve seat and is in communication with the fuel chamber, and an outlet downstream of the valve seat. The outlet is coaxially aligned with the passage of the fuel supply pipe and the fuel valve is electrically operated to move the valve element.Type: GrantFiled: February 2, 2024Date of Patent: October 22, 2024Assignee: Walbro LLCInventors: William E. Galka, Bryan K. Gangler, Jeffrey C. Hoppe, Adam M. McGilton, Bradley J. Roche, Albert L. Sayers, David L. Speirs
