摘要： A fuel feed apparatus includes a sub-tank and a fuel pump that are received in the fuel tank. The sub-tank has an inner space that is partitioned into at least a first chamber and a second chamber. The fuel pump is arranged in the first chamber to discharge fuel received in the sub-tank to the outside of the fuel tank. The second chamber has an opening, through which the second chamber communicates with the outside of the sub-tank such that fuel accumulated in the second chamber is exhausted to the outside of the sub-tank through the opening. The fuel tank has a first tank space and a second tank space. The sub-tank is received in the first tank space. A first jet pump is disposed in the second chamber of the sub-tank. The first jet pump draws fuel accumulated in the second tank space into the first tank space.

摘要： A fuel feed apparatus includes a lid member, a sub-tank, first and second supporting members, a biasing means, a supporting portion, and a guide portion. The first and second supporting members are arranged in substantially radially end portions of the cylindrical portion to be substantially radially opposed to each other. The lid member is capable of axially moving relative to the sub-tank via the first and second supporting members. The biasing means is arranged on the outer periphery of the first supporting member, and is received in the guide portion to bias the lid member and the sub-tank to be apart from each other. The first supporting member defines a groove portion that circumferentially divides an inner wall thereof into at least two planes. The first supporting member is capable of axially reciprocating through the supporting portion.

摘要： A pump unit having a fuel pump and a suction filter is provided in a sub tank of a fuel tank. A filter element sheet for the suction filter is formed in a cup shape, a bottom wall portion of which faces to an inner bottom surface of the sub tank. A suction port of the fuel pump is opened to a fuel passage formed in the inside of the suction filter, so that filtered fuel is sucked into the fuel pump. Multiple mountain fold portions and multiple valley fold portions are formed on a side wall of the cup-shaped filter element sheet, to thereby increase surface area for filtering the fuel.

摘要： A reservoir is located in a fuel tank. The reservoir is in a bottomed tubular shape having a periphery defining an opening. A lid member is located in the fuel tank and mounted to the periphery of the reservoir to close the opening. A pump unit is partially accommodated in the reservoir to discharge fuel stored in the reservoir to an exterior of the fuel tank. The pump unit is located at a position offset from a center axis of the lid member. The pump unit has a projection projected from the lid member to an exterior of the reservoir. A remaining quantity detector is configured to detect a quantity of fuel in the fuel tank. The remaining quantity detector is located at a remaining space remaining in the fuel tank.

摘要： A support shaft connects between a flange and a pump unit. An intermediate member, which connects between the support shaft and pump unit, enables a relative positional change between the support shaft and the pump unit in an axial direction of the support shaft. The intermediate member limits a relative positional change between the support shaft and the pump unit in a circumferential direction of the support shaft. A resilient member is received in the support shaft and exerts a restoring force in an axial direction of the support shaft to urge the pump unit, which is movable relative to the support shaft in the axial direction, toward a bottom portion of the fuel tank.

摘要： A fuel supply device is composed of a bottom cover closing a bottom opening of a fuel tank and a fuel pump module mounted on the bottom cover. The fuel pump module includes a fuel pump for sucking fuel contained in the fuel tank, a pressure regulator for regulating fuel pressure by discharging part of the fuel sucked by the fuel pump and a fuel level detector for detecting a fuel level in the fuel tank. The fuel pump module is submerged in fuel contained in the fuel tank. The fuel level detector is positioned apart from the pressure regulator in both the horizontal and vertical directions, so that the fuel level detector accurately detects the fuel level without being disturbed by a fuel flow discharged from the pressure regulator.

摘要： A filter element has a wavy filter portion including a plurality of ridges of a filter material, which are juxtaposed to one another and closed at their sides, and a flange portion extending along a mounting plane around the filter portion for supporting the filter portion. The flange portion is made of the same filter material extending from the filter portion, by compressing the filter material more densely than the filter portion. The filter element is manufactured by a step of preparing an intermediate product of a wavy sheet, and a step of forming the filter portion by leaving the central portion of the wavy intermediate product as in the wavy sheet, and forming the flange portion around the filter portion for supporting the filter portion, by pressing the side portions of the ridges of the wavy intermediate product along the mounting plane.
