摘要： In a fuel supply device disposed in a fuel tank, a pump module is constructed with at least a fuel pump, a fuel filter and a pressure regulator, and is installed in a sub-tank. A filter case of the fuel filter has first ribs and second ribs, so that an axially position between the pump module and the sub-tank is set by the first ribs, and a circumferential position therebetween is set by the second ribs. Further, a fuel inlet of a jet pump is formed in an inner bottom surface of the sub-tank, and an inner surface of the fuel inlet of the jet pump is tapered. Therefore, a fuel outlet of the pressure regulator is guided while being connected to the fuel inlet of the jet pump. Accordingly, the fuel supply device can be assembled easily.

摘要： A fuel feed apparatus is accommodated in a fuel tank. Hooking projection parts have claws formed on a fuel discharge side of a fuel pump. The claws are fitted and hooked in an opening formed on a filter case, so that the fuel pump is protected from dropping out from the filter case. The entire circumference of the fuel discharge side of the fuel pump is inserted with force into a press-insertion part formed in the filter case. A fuel suction side of the fuel pump is not supported by other parts, so it is in free condition.

摘要： A fuel feed apparatus accommodates a sub tank. The sub tank includes a pump module The pump module generates vibration, and is supported by a supporting member and a suction filter. The suction filter is covered with a nonwoven fabric. The nonwoven fabric is used as an additional filter for removing debris in fuel drawn by the pump module. The supporting member and the nonwoven fabric have resilience. The pump module is mounted on the sub tank via the supporting member and the non woven fabric. Therefore, vibration of the pump module is not apt to be transmitted to the sub tank. Additionally, the supporting member need not to be rigidly formed, so that the supporting member can be manufactured easily.

摘要： An impeller is employed for a fuel pump and boosts a pressure of fuel by rotating the fuel in a pump passage formed in the fuel pump in a rotational direction of the impeller. The impeller includes a plurality of vane grooves formed adjacent to each other in the rotational direction of the impeller and a plurality of vanes formed adjacent to each other in the rotational direction. Each one of the plurality of vanes divides one of adjacent two of the plurality of vane grooves from the other. A difference between a maximal value and a minimum value of an adjacent vane angle is set in a range of 2.5° to 4°. A fuel pump includes a motor unit, the impeller, and a casing member. The impeller is rotated by rotation driving force of the motor unit. The casing member rotatably receives the impeller and defines the pump passage.

摘要： A plane commutator includes a plurality of commutator segments made of carbon compound, a resinous boss member having a body portion supporting a base portion of the commutator segments and an outer peripheral portion supporting an outer periphery of the same and a plurality of metal base plates. Each metal base plate has a contact portion in contact with the base portion of the commutator segment, an axial portion extending along a peripheral portion of the boss member and a terminal portion. The axial portion of the metal base plates is disposed on an outer periphery of the plane commutator in parallel with the outer peripheral portions of the boss member to separate the outer peripheral portion from the body portion. The outer peripheral portion moves freely from the body portion as the metal base plates thermally expand.

摘要： A casing includes a C-shaped casing side pump groove along blades of an impeller. A casing cover also includes a casing cover side pump groove facing the casing side pump groove. The casing side pump groove and the casing cover side pump groove form a pump fluid passage. A gap is provided between an outer surface of the pump grooves and the impeller. Depth, and outer and inner diameters of a pump groove starts to gradually change from a fuel upstream side of a fuel outlet. The depth of the pump groove gradually decreases, the outer diameter of the pump groove gradually decreases to approach an outer diameter of the impeller, and the inner diameter of the pump groove gradually increases to approach the outer diameter of the impeller. The pump groove ends at a downstream side of the fuel outlet.

摘要： A fluid supply device such as a fuel pump has an impeller 24 on which vanes and vane grooves are arranged alternately on its outer circumference. All adjacent groove angles, each of which is defined by the adjacent two vane grooves, are different from each other. Among the arrangement of the vane grooves, a sum Sm of the angles of the vane grooves which are adjacent in succession in the number of m=n/k (k=2, 3 and 4) is determined. If the number n/k is not an integer, at least (n/k)+1 between n/k and (n/k)+1 is set as m. The sum Sm is determined n-times by shifting the vane groove, from which the sum is determined each time, in the circumferential direction one by one. The arrangement in which the sum Sm of each time satisfies the following relation is adopted: (360/k)-10.ltoreq.Sm.ltoreq.(360/k)+10.

摘要： The Cu-based sintered alloy bearing of the present invention is made of a Cu-based sintered alloy with a composition consisting of, by weight, Ni: 10 to 25%, Zn: 10 to 25%, P: 0.1 to 0.9%, C: 0 to 5%, molybdenum disulfide: 0.5 to 5%, and Cu and inevitable impurities as the balance. The Cu-based sintered alloy has a texture from a Cu—P compound, free graphite, and molybdenum disulfide being dispersed in a base material made of a solid solution phase of a Cu—Ni—Zn alloy, and a porosity is within a range of 5 to 25%.
