  • Patent number: 7278404
    Abstract: A fuel supply system for supplying an internal combustion engine with fuel comprises an electric fuel pump arranged with a fuel tank. A fuel line leading to the internal combustion engine is connected with the fuel pump. A return line returning fuel toward the fuel pump is connected with the fuel line. Further, a shunt is connected with the fuel line via which a sucking jet pump arranged in the fuel tank is operated. The fuel supply system comprises a pressure control system that opens or closes the connection of the shunt to the fuel line at a first pressure and opens or closes the connection of the return line with the fuel line at a second pressure. When the pressure increases, the shunt and the return line are opened by the pressure control system, and when the pressure drops, they are closed.

  • Patent number: 4191149
    Abstract: A carburetor has a float chamber and a device for adjusting the gaseous pressure in the float chamber. The device comprises a pressure source and a probe contacting the exhaust gas and delivering a signal which is a function of the exhaust gas composition. The device has an airflow pipe connecting the source to atmosphere, a throttle for impressing a head loss to the flow and controlled by the probe and a venturi located in the pipe and connected to the float chamber for giving a pressure which may be out of the range between the source pressure and atmospheric pressure.
