Abstract: PROBLEM TO BE SOLVED: To provide a fuel supply device inhibiting rotation of a stay in a circumferential direction without increasing the number of parts and assembling man-hours.
SOLUTION: The stay 40 has at an end of a flange 11 side a rotation stopper 42 for inhibiting relative rotation with a press-fit portion 15 of a flange 11. The rotation stopper 42 has an elliptic shape in the cross section perpendicular to an axis and a hole portion 16 in which the stay 40 is press-fitted has an elliptic shape similar to the cross-sectional shape of the rotation stopper 42 in the cross section perpendicular to the axis. The rotation stopper 42 of the stay 40 is therefore not rotated in the hole portion 16 of the flange 11. Even when force is applied in the circumferential direction of the stay 40, rotation of the stay 40 is regulated by the rotation stopper 42.

Abstract: PROBLEM TO BE SOLVED: To provide a fuel supply device enabling the easy commonization of a pump module and capable of reducing noise.
SOLUTION: A shaft 30 connects a flange 12 to the case body 26 of the pump module 20. One of the shaft 30 is press-fitted to the press-fitted part 13 of a flange 12, and the other is inserted into a projected part 28 projected from the side of a filter case 24. Rubber parts 40 of the same shape are fitted to opening parts in both axial sides of the projected part 28. On the flange 12 side and the anti-flange side of the projected part 28, a washer 50 is fitted to a small diameter part 32 so as to hold a vibration isolation member 40 in the clearance thereof from the projected part 28. A clip 52 is fitted to the small diameter part 32 on the opposite side of the vibration isolating member 40 of the lower side washer 50. The clip 52 prevents the shaft 20 from coming off the projected part 28.

Abstract: PROBLEM TO BE SOLVED: To provide a fuel supply device capable of easily determining the position of a component relative to a support member without causing an increase in man-hours for processing.
SOLUTION: A stopper member 40 is installed on the outer periphery of a shaft 15. Accordingly, a step for determining the position of a flange 11 relative to a pump module 20 is formed. The shaft 15 may be formed in a bar shape having a roughly same outer diameter in the axial direction. Thus, the shaft 15 can be easily processed and the man-hours for processing the shaft 15 can be reduced. Also, since the stopper member 40 is fitted to the shaft 15, the movement of the connection part 30 of the pump module 20 is limited by the stopper member 40. As a result, the position of the pump module 20 relative to the shaft 15 can be easily and accurately determined.

Abstract: PROBLEM TO BE SOLVED: To provide a fuel supply device capable of accurately detecting the liquid level of a fuel in a fuel tank. SOLUTION: A level gauge 25 is positioned above a pressure regulator 24 in the vertical direction. Also, the pressure regulator 24 and the level gauge 25 are installed on both sides of a fuel pump 21 in the axial and radial directions of the fuel pump 21. Accordingly, the streamline of the excess fuel discharged from the pressure regulator 24 is deviated from the level gauge 25 and the fuel discharged from the pressure regulator 24 does not directly strike the level gauge 25. Thus, the level gauge 25 can be prevented from mis-operating, and increase detection accuracy for the level of the fuel in the fuel tank 2. In addition, the fuel discharged from the pressure regulator 24 is limited to flow by a tube part 15, and accumulated near a suction filter 23. As a result, the fuel pump 21 can suck the fuel to the end. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a fuel supply device capable of easily supporting a fuel pump and a fuel filter pump module inside a fuel tank, commonizing a pump module, and easily changing installation height or angles of the pump module inside the fuel tank.
SOLUTION: A flange 12 of the fuel supply device 10 is attached on a bottom wall 2 of the fuel tank 1 to close an opening part 2a formed on the bottom wall 2. The pump module 20 includes the fuel pump 21, a fuel filter 22 and a pressure regulator 60 or the like. A cylindrical part 27 is formed projectingly from a side of a filter case 24. One side of a shaft 30 is press-fitted in a press-fit part 13 of the flange 12 and another side of the shaft 30 is inserted in the cylindrical part 27. The shaft 30 prevents the pump module 20 from falling off by locking the cylindrical part 27 via a vibration isolating member 40 and a washer 50 with a step 34 of the shaft.

Abstract: PROBLEM TO BE SOLVED: To provide a fuel supplying device in which the position of a detection means can be easily changed and common use of components and designs can be realized.
SOLUTION: A center gage 50 is mounted to a stay 60 separated from a flange 20 and a bracket 43 which support a fuel pump 30. Accordingly, the mounting position of the center gage 50 can be arbitrarily set without changing the shape of each member of the fuel supplying device 1 including the flange 20 and the bracket 43 by changing the shape of the stay 60. As a result, the position of the center gage 50 can be changed to the position where interference with a float member 54, a fuel tank 10, a sub-tank 12 or a suction filter 31 can be prevented without causing design changes of the flange 20 and the bracket 43 or the like.

Abstract: PROBLEM TO BE SOLVED: To improve the reliability of assemblability and opening/closing operation of a fuel leak prevention valve. SOLUTION: The plural number of elastic pieces 42 are molded en bloc downwardly at the lower end of the peripheral wall of a mounting hole 4 formed in a supporting bracket 11, and a convex fitting part 43 is molded en bloc on the inner surface of the lower end of each elastic piece 42. Correspondingly to this, a concave fitted part 44 is formed on the entire periphery of the outer circumferential surface of a housing 25 of a fuel leak prevention valve 14. Then, the housing 25 is assembled to the mounting hole 41 by inserting the housing 25 into the mounting hole 41 of the supporting bracket 11 from above and elastically fitting the fitting part 43 of each elastic piece 42 into the fitted part 44 of the housing 25. In this case, rotation of the housing 25 in the circumferential direction is prevented by fitting a convex engagement part 48 formed at the upper end of the housing 25 into a rotation prevention part 47 formed at the upper end of the peripheral wall of the mounting hole 41, and a gap between the housing 25 and the inner circumferential surface of the mounting hole 41 is sealed by an O-ring 46.
