    摘要: 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. When the internal combustion engine is started, the fuel line is thus only connected with the internal combustion engine so that the starting procedure is accelerated whereby the electric fuel pump is supplied with sufficient power more quickly so that the fuel supply of the internal combustion engine is improved.

    摘要: A side channel pump having a housing, a pump mechanism including an impeller in the housing to pump liquid from an inlet of the pump to an outlet of the pump, and first and second end cover members on opposite sides of the impeller, at least one of the cover members having a side channel therein for flow of the liquid from the inlet to the outlet. The cover member is made as an assembly of a ceramic body and a plastic unit. The ceramic body has a slot therein into which the plastic inlet is fitted. The plastic unit has an open channel facing the impeller to form the side channel of the pump and the side channel tapers in cross-section from the inlet to the outlet.

    摘要: An electric fuel pump mountable in a fuel tank for pumping fuel to an internal combustion engine. A casing of the fuel pump is mountable at a bottom wall of the fuel tank and has a fuel inlet at a lower end and a fuel outlet at an upper end so that the fuel is pumped upwardly through the casing. A vent valve is disposed at the top of the casing and is closed when the fuel pump is operating and opened when the fuel pump is deactivated. A conduit has one end connected to the vent valve and an opposite end which is open and located at a level in proximity to the bottom of the fuel tank so that when the fuel pump is deactivated the conduit serves as a suction passage to fill the casing when the fuel level in the fuel tank drops below the top of the casing to enable restarting of the engine without delay.
