Hereinafter, with reference to the drawings, an embodiment in which the present invention is applied to a fuel filler apparatus provided in a fuel filler of an automobile will be described in detail. In the following description, the vertical direction refers to the direction along the vertical direction V as shown in FIGS.

As shown in FIGS. 1 and 2, the fuel filler apparatus 1 is provided at the outer end of a fuel pipe 2 connected to a fuel tank (not shown), and normally closes the outer end of the fuel pipe 2. On the other hand, the outer end of the oil supply pipe 2 is opened when the oil supply nozzle 100 is inserted. The fuel supply pipe 2 has an end portion side serving as a fuel supply port as an outer end side and an end portion side connected to the fuel tank as an inner end side with respect to the longitudinal direction.

The oil supply pipe 2 is a metal pipe, and is a truncated cone-shaped enlarged diameter portion 5 that gradually increases in diameter toward the outer end side, and an equal-diameter cylinder continuous to the outer end side of the enlarged diameter portion 5. And an outer end 6. The outer end 6 has an open end and is provided with an outward flange 7. The oil supply pipe 2 is attached to the vehicle body panel 11 at the flange 7. In the present embodiment, the outer end portion 6 is configured as a part of the oil supply pipe 2, but in other embodiments, the outer end portion 6 is configured as a separate member from the oil supply pipe 2, and the outer end portion 6 is coupled to the oil supply pipe 2. You may make it make it. In this case, the outer end portion 6 may be formed of a resin material.

As shown in FIG. 2, when the axial direction parallel to the axis of the outer end portion 6 is the Z direction, the outer end portion 6 is the vehicle body so that the angle θ formed by the vertical direction V and the Z direction is greater than 0 degrees. It is attached to the panel 11. The angle θ is preferably 30 degrees to 80 degrees, for example. Further, from the viewpoint of explanation, the direction parallel to the intersection line between the plane perpendicular to the Z direction (cross section of the outer end 6) and the plane including the Z direction and the vertical direction V is defined as the X direction, and is orthogonal to the X direction. A publication that is parallel to the line of intersection between the plane that is perpendicular to the Z direction and the plane that is perpendicular to the Z direction is defined as the Y direction (see FIGS. 1 and 2).

1 and 2, the fuel filler apparatus 1 has a main body member 13 as a skeleton. The main body member 13 is configured by combining the inner member 14 and the outer member 15. The inner member 14 is formed in a disk shape having a thickness, and is fitted into the outer end portion 6 such that the outer peripheral portion thereof faces the inner peripheral portion of the outer end portion 6. The inner member 14 has an enlarged diameter portion 16 that protrudes radially outward on the outer end side. An insertion depth of the inner member 14 with respect to the outer end portion 6 is determined by the enlarged diameter portion 16 coming into contact with the flange 7 of the outer end portion 6. An elastic claw 17 is formed on the outer peripheral portion of the inner member 14. The inner member 14 is held by the outer end portion 6 by the elastic claw 17 being caught in the through hole 18 formed in the outer end portion 6. An annular seal member 19 is attached to the outer peripheral portion of the inner member 14 and on the inner end side of the elastic claw 17. The seal member 19 seals between the outer peripheral surface of the inner member 14 and the inner peripheral surface of the outer end portion 6.

A first passage 21 that penetrates the inner member 14 in the thickness direction (Z direction) is formed in a substantially central portion of the inner member 14 (specifically, a position slightly deviated downward in the X direction from the center). As shown in FIGS. 2 and 3, a positive pressure valve 23 and a negative pressure valve 24 are provided in a portion located above the first passage 21 in the X direction of the inner member 14. The positive pressure valve 23 and the negative pressure valve 24 are respectively a passage communicating the inner end side and the outer end side of the inner member 14, a valve seat provided in the passage, and a valve body that is seated on the valve seat and closes the passage. And a compression coil spring that urges the valve body toward the valve seat. When the inner end side of the inner member 14 has a positive pressure equal to or greater than a predetermined value, the positive pressure valve 23 moves the pressure in a direction to separate the valve body from the valve seat against the biasing force of the compression coil spring. And the pressure on the inner end side of the inner member 14 is reduced. On the other hand, when the inner end side of the inner member 14 has a negative pressure equal to or less than a predetermined value, the negative pressure valve 24 moves the pressure in a direction to separate the valve body from the valve seat against the biasing force of the compression coil spring. Then, the passage is opened and the pressure on the inner end side of the inner member 14 is increased. The action of the positive pressure valve 23 and the negative pressure valve 24 prevents the inner end side of the inner member 14 from becoming a high pressure equal to or higher than a predetermined value or a low pressure equal to or higher than a predetermined value.

The outer member 15 is a disk-like member having substantially the same diameter as the inner member 14 and is disposed on the outer end side of the inner member 14 to constitute the outer surface of the fuel filler opening. In the outer peripheral portion of the outer member 15, a thinned portion 27 that opens to the inner end side is formed in an annular shape. On the outer peripheral surface of the outer member 15, a locking hole 28 that penetrates to the thinned portion 27 is formed. A locking claw 29 projects from the outer peripheral surface of the enlarged diameter portion 16 of the inner member 14. The inner diameter member 16 and the outer member 15 are joined by the enlarged diameter portion 16 entering the lightening portion 27 and the locking claw 29 being caught in the locking hole 28.

A second passage 31 that penetrates the outer member 15 in the thickness direction (Z direction) is formed at a substantially central portion of the outer member 15. The second passage 31 is substantially the same diameter and coaxial with the first passage 21. The first passage 21 and the second passage 31 have an axis parallel to the Z direction and form a passage 32 that penetrates the main body member 13.

The outer member 15 is a hole wall portion that defines the second passage 31, and extends to the inner end side in a portion located below the axis of the second passage 31 (a portion located below in the X direction). An extension wall 33 is provided. An end of the extension wall 33 on the inner end side is separated from the inner member 14 in the Z direction, and defines a first discharge passage 35 extending in the substantially X direction between the inner member 14 and the inner member 14. The upper side in the X direction of the first discharge passage 35 communicates with the first passage 21, and the lower side is connected to the outer peripheral surface of the inner member 14 via the second discharge passage 36 which is a through hole formed in the inner member 14. Communicate. A portion of the outer end 6 corresponding to the second discharge passage 36 is formed with a third discharge passage 37 that communicates the inside and the outside of the outer end 6. A discharge passage 38 including a first discharge passage 35, a second discharge passage 36, and a third discharge passage 37 is formed between the passage 32 and the outer peripheral surface of the outer end portion 6 below the axis of the fuel supply pipe 2 (the axis of the passage 32). Communicate.

The flap 40 is used to close the inner end side end (opening end) of the first passage 21, and is formed by overlapping the first disc 41 and the second disc 42 so as to overlap each other. An annular seal member 43 having an outer diameter larger than that of the first disc 41 is sandwiched between the first disc 41 and the second disc 42. The outer peripheral portion of the seal member 43 protrudes radially outward from the peripheral portions of the first disc 41 and the second disc 42 to form a flexible annular lip piece. As shown in FIGS. 4 to 6 with the flap 40 closing the first passage 21 as a reference, a pair of bearing arms 44 project in parallel to each other at the lower peripheral edge in the X direction of the second disc 42. A stopper 45, which is a protruding piece, protrudes from the other peripheral edge. The pair of bearing arms 44 have bearing holes in which the respective axes are parallel to the Y direction and are coaxial with each other.

A support shaft 47 extending in the Y direction is provided at a portion on the inner end side of the inner member 14 and located below the first passage 21 in the X direction. The flap 40 is rotatably supported with respect to the inner member 14 by pivotally supporting the bearing arm 44. The flap 40 rotates about the support shaft 47 as a rotation shaft, and the first passage 21 can be opened and closed. In a state where the flap 40 is in a closed position that closes the first passage 21, the first disc 41 is disposed on the outer end side and enters the first passage 21, and the second disc 42 is the first disc. The seal member 43 is disposed on the inner end side of the first passage 21 and abuts against the peripheral edge of the inner end side opening end of the first passage 21 to seal the gap between the first disc 41 and the first passage 21.

In the closed position of the flap 40, the stopper 45 comes into contact with the inner end side portion of the first passage 21 via the seal member 43, and the claw portion 48 protruding from the wall surface of the first passage 21 has the first disc 41. It is determined by contacting the peripheral edge of the Further, the stopper 45 is disposed between the two guide walls 49 (see FIG. 3) protruding from the inner end surface of the inner member 14, whereby the flap 40 is displaced and deformed in the Y direction with respect to the inner member 14. It is regulated. The end portions on the inner end side of the pair of guide walls 49 are formed such that the distance between the guide walls 49 increases as the distance from the guide wall 49 increases toward the inner end side. The stopper 45 is easily guided between the guide walls 49.

A torsion coil spring 50 is interposed between the second disk 42 and the inner member 14, and the flap 40 is normally biased to the closed position. The coil portion of the torsion coil spring 50 is supported by the support shaft 47.

As shown in FIGS. 1 and 2, when the flap 40 is in the closed position, the surface facing the outer end side is defined as the outer surface 51 of the flap 40 (first disc 41). A portion where the bearing arm 44 (support shaft 47) is provided in the X direction of the flap 40 is a base end, and an opposite portion (a portion where the stopper 45 is provided) is a free end. In the closed position, the flap 40 and its outer surface 51 are inclined with respect to the horizontal direction so that the base end is disposed below the free end.

The outer surface 51 includes a plurality of

ribs

52 and 53 extending in a first direction (X direction) extending from the base end to the free end, and a plurality of locking walls 54 formed between the

ribs

52 and 53. Is formed. In the present embodiment, four

ribs

52 and 53 are provided and are arranged in parallel with a space between each other. The two ribs 52 provided at both ends in the second direction (Y direction) orthogonal to the first direction of the outer surface 51 protrude in the Z direction more than the two ribs 53 provided on the center side of them. The length is getting bigger.

Each locking wall 54 extends in the second direction (Y direction), and a plurality of the locking walls 54 are arranged in the first direction (X direction) between the

ribs

52 and 53. In the first direction, a bottom surface 56 that is a plane extending in the first direction and the second direction is formed between the adjacent locking walls 54. A locking surface 57 facing the base end side is formed on the base end side portion of each locking wall 54. The locking surface 57 is substantially perpendicular to the bottom surface 56. An inclined surface 58 that continues from the protruding end of the locking wall 54 to the bottom portion disposed on the free end side of the locking wall 54 is formed at the free end side portion of each locking wall 54. In other words, the inclined surface 58 is a slope that protrudes from the bottom surface 56 as it proceeds from the free end side to the proximal end side. The protruding end of the locking wall 54 is located lower (inner end side) than the protruding ends of the

ribs

52 and 53. The locking walls 54 adjacent in the first direction define a recess (reservoir) 59 composed of a locking surface 57, a bottom surface 56, and an inclined surface 58 therebetween.

Next, the operation of the fuel filler apparatus 1 will be described. As shown in FIGS. 1 and 2, in a normal state in which fueling by the fueling nozzle 100 is not performed, the flap 40 is in a closed position in which the first passage 21 is closed by being biased by the torsion coil spring 50.

In the case of injecting fuel into the fuel supply pipe 2 using the fuel filler nozzle 100 from the normal state, that is, when fueling, the cylindrical fuel filler nozzle 100 is connected to the passage 32 (second passage 31 and second passage 31) of the fuel filler apparatus 1. Insert into one passage 21). At this time, since the second passage 31 is set to a predetermined diameter, insertion of the fuel nozzle 100 having an outer diameter larger than that of the second passage 31 is prohibited.

When the fueling nozzle 100 is moved toward the inner end in the passage 32, the tip of the fueling nozzle 100 comes into contact with the

ribs

52 and 53 of the flap 40. When the oil supply nozzle 100 is further pushed into the inner end side from this state, the tip of the oil supply nozzle 100 slides on the

ribs

52 and 53 toward the free end side, and the flap 40 is twisted to urge the coil spring 50. Rotate to open position while resisting. FIG. 7 shows a state in which the flap 40 is in the open position. As shown in FIG. 7, in the open position of the flap 40, the outer surface 51 of the flap 40 has a direction extending from the base end side to the free end side substantially coincides with the Z direction and faces obliquely upward. In a state where the flap 40 is in the open position, the locking surface 57 is arranged to have an elevation angle with respect to the horizontal plane. In this state, the user can inject fuel from the fueling nozzle 100.

When the fuel filler nozzle 100 is pulled out from the fuel filler apparatus 1, the flap 40 is biased by the torsion coil spring 50 and moves to the closed position as the fuel nozzle 100 is displaced to the outer end side. Close the passage 21 and return to the normal state.

The effect of the fuel filler apparatus 1 of this embodiment will be described. The fuel filler apparatus 1 holds foreign matter such as rainwater and dust that has passed through the passage 32 and reached the outer surface 51 of the flap 40 in a recess 59 formed between the adjacent locking walls 54 in the first direction. be able to. When the flap 40 is in the open position, the free end of the flap 40 is disposed below the base end, but the foreign matter is caught on the locking surface 57 and is prevented from falling into the fuel supply pipe 2. In particular, in this embodiment, when the flap 40 is in the closed position, the locking surface 57 has an elevation angle with respect to the horizontal plane, so that the locking surface 57 can reliably catch foreign matter. The angle of the locking surface 57 with respect to the horizontal plane is such that the oil supply pipe 2 and the passage 32 are arranged to be inclined with respect to the vertical direction V, and the rotation axis (support shaft 47) of the flap 40 is below the axis of the oil supply pipe 2. The outer surface 51 of the flap 40 is set so as to face obliquely upward in the open position.

Since the recess 59 formed between the locking walls 54 is sufficiently smaller than the tip of the fuel nozzle 100, the tip of the fuel nozzle 100 cannot enter the locking wall 54 or contact the bottom surface 56. Therefore, when the flap 40 is pressed by the fuel supply nozzle 100 so as to open the flap 40 by the fuel supply nozzle 100, the fuel supply nozzle 100 is prevented from scraping and collecting foreign matter in the locking wall 54. Further, in the present embodiment, the

ribs

52 and 53 are further provided so that the oil supply nozzle 100 contacts only with the

ribs

52 and 53 and does not contact the locking surface 57 and the inclined surface 58 of the locking wall 54. The oil supply nozzle 100 does not scrape and collect foreign matter accumulated in the recess 59 or on the locking wall 54.

Further, when the flap 40 is in the closed position, the outer surface 51 is inclined so that the base end is disposed below the free end, so that the foreign matter easily moves to the base end side of the flap 40. . Since a discharge passage 38 is provided at a portion corresponding to the base end of the flap 40, the foreign matter moved to the base end side of the flap 40 passes through the discharge passage 38 and is discharged to the outside of the fuel supply pipe 2. In particular, since the base end side portion of the locking wall 54 is an inclined surface 58, the foreign matter easily passes through the inclined surface 58 and is easily detached from the locking wall 54. If the inclined surface 58 has a depression angle with respect to the horizontal plane when the flap 40 is in the closed position, the movement of the foreign matter toward the base end side becomes smooth, which is preferable. Since the liquid can easily flow through the inclined surface 58 and the outer surface 51 to the proximal end side, the fuel filler apparatus 1 can clean the inside of the passage 32 and the outer surface 51 of the flap 40 by water discharge. it can.

This is the end of the description of the specific embodiment, but the present invention is not limited to the above-described embodiment, and can be widely modified. For example, the

ribs

52 and 53 may be omitted. In this case, the size of the recess 59 may be sufficiently smaller than the oil supply nozzle 100 so that the tip of the oil supply nozzle 100 is not caught by the locking wall 54. In the embodiment, the position of the support shaft 47 is set so that the outer surface 51 of the flap 40 faces obliquely upward in the open position. However, in other embodiments, the outer surface 51 of the flap 40 is in the vertical position in the open position. You may make it face in the direction orthogonal to the direction V, or diagonally downward. In this case, although the ability to hold the foreign matter on the locking wall 54 is reduced as compared with the embodiment, the locking surface 57 can lock some foreign matter.

The angle of the locking surface 57 with respect to the bottom surface 56 can be changed as appropriate. For example, the locking surface 57 is overhanged with respect to the bottom surface 56 (the protruding end of the locking surface 57 protrudes toward the base end side of the flap 40 with respect to the base end). 57 makes it easier to catch foreign matter. Further, the locking surface 57 may be formed as a concave surface to form a pocket.

In the embodiment, the main body member 13 and the flap 40 are formed by combining a plurality of members, but may be formed from a single member. In particular, in the present embodiment, the first discharge passage 35 is a gap between the inner member 14 and the outer member 15, but may be formed by providing a through hole in the inner member 14.
