摘要： In a fuel supply system, a fuel pump supplies fuel from a fuel tank to a fuel supply piping and to a back pressure introducing passage. A pressure regulator has a fuel pressure regulating chamber communicated to the fuel supply piping, and a back pressure chamber communicated to the back pressure introducing passage. When a fuel pressure in the fuel pressure regulating chamber is larger than a relief pressure that bulges the diaphragm toward the back pressure chamber, a relief valve opens a relief port to return the fuel from the fuel pressure regulating chamber to the fuel tank. The relief pressure is adjusted by controlling a fuel pressure in the back pressure chamber of the pressure regulator.

摘要： An impeller includes vane grooves arranged with respect to the rotative direction. At least the radially inner side of a back surface of each vane groove is radially outwardly inclined backwardly with respect to the rotative direction. The back surface has a radially inner end and a radially outer end, which are connected via a line segment. The line segment and a radius of the impeller define a backward inclining angle α therebetween. The back surface is inclined from a thickness center of the impeller toward each thickness-end of the impeller forwardly with respect to the rotative direction. The thickness-center and the thickness-end are connected via a line segment. The line segment and the thickness-center define a forward inclining angle β therebetween. The angle α, β satisfy the following relationships: 15°≦α≦30°; β≦60°; and 1≦β/α≦4.

摘要： The Fuel supply system reduces fuel quantity initially supplied and ineffective residual quantity of fuel. A throat in the shape of a passage is provided at a bottom portion of a sub-tank that supplies fuel from the fuel tank to the interior of the sub-tank by a jet pump. The throat has a suction port communicating with the exterior of the sub-tank and a supply port communicating with the interior of the sub-tank. The throat is inclined with respect to a bottom surface of the tank so that the height of the throat increases gradually from the suction port toward the supply port. The sub-tank has a check valve for opening and closing the supply port. This check valve prevents the fuel in the sub-tank from flowing out to the exterior of the sub-tank through the throat and becomes substantially vertical during valve closing.
