Description

  The present invention relates to a fuel supply device, and more particularly to a fuel supply device for supplying fuel in a fuel tank to an engine or the like.

  The fuel supply device that supplies the fuel in the fuel tank to an external device such as an engine is provided with a fuel filter in the fuel tank main body, and the fuel in a state in which foreign matters have been removed by the fuel filter is transferred from the fuel filter to the outside There is something to send out. For example, Patent Document 1 describes a structure in which a protector having rigidity is surrounded by a filter cloth.

  In the structure of Patent Document 1, since the space in the filter cloth is secured by the protector, the fuel can be maintained in the filter cloth when the fuel tank is level. However, if the fuel in the fuel tank moves away from the filter cloth when the fuel tank tilts or G acts on the fuel tank (hereinafter collectively referred to as “when the fuel level is tilted”), Since the oil film on the surface of the cloth is broken and the fuel in the filter cloth flows out to the outside (in the fuel tank), so-called fuel shortage may occur.

  On the other hand, Non-Patent Document 1 describes a fuel supply device in which a cell-shaped cup is arranged on the upper surface of a suction filter, and a certain amount of fuel held in the cup is supplied to the filter.

  The structure of Non-Patent Document 1 can be expected to have an effect of suppressing the occurrence of fuel shortage, but it is desired to further reliably suppress the occurrence of fuel shortage and to reliably deliver fuel to the outside.

  In view of the above facts, an object of the present invention is to obtain a fuel supply device that can suppress the occurrence of fuel shortage and reliably deliver fuel to the outside even when the fuel level of the fuel tank body is inclined.

  According to the first aspect of the present invention, a fuel tank body that contains fuel, a bag-like body that is provided in the fuel tank body, removes foreign matters from the fuel when the fuel flows therein, and The fuel filter is provided with a fuel filter in which an oil film is formed on the surface when the part or the whole is immersed in the fuel, and a delivery pipe extending from the inside of the fuel filter to the outside of the fuel tank body. And a storage member that is provided above the fuel filter and has a bottom portion constituted by at least a part of the upper surface of the fuel filter, capable of storing fuel, the storage member, and the storage member And a cover plate portion formed with an inflow hole for allowing fuel to flow into the storage member, and at least a part of the lower end in contact with the upper surface of the fuel filter toward the cover plate portion. Is erected I, having a rib at least partly in a non-contact with respect to the cover plate portion.

  In this fuel supply device, the fuel accommodated in the fuel tank body passes through the fuel filter (at this time, the foreign matter of the fuel is removed) and flows into the fuel filter. Then, the fuel inside the fuel filter is sent to the outside through the delivery pipe by the delivery means. When a part or all of the fuel filter is immersed in the fuel, a fuel oil film is formed on the surface, so that the fuel in the fuel filter does not flow out. Thereby, the fuel can be sent to the outside without causing the fuel to run out.

  A storage member capable of storing fuel is provided above the fuel filter. The bottom of the storage member is constituted by at least a part of the upper surface of the fuel filter. Therefore, even if the fuel in the fuel tank (outside of the storage member) is separated from the fuel filter when the fuel level of the fuel tank body is inclined, the fuel stored in the storage member touches the upper surface of the fuel filter. Therefore, the oil film on the surface of the fuel filter is maintained. Thereby, the outflow of the fuel in the fuel filter can be prevented, and the fuel can be sent to the outside without causing the fuel to run out.

  And the upper part of the storage member is covered with the cover board part. Therefore, even when the fuel tank body is inclined, the amount of fuel flowing out from the storage member can be reduced. Since the inflow hole is formed in the lid plate portion, for example, if the fuel level in the fuel tank body is located above the inflow hole, the fuel flows into the storage member from the inflow hole.

  In addition, this fuel supply device has a rib that contacts at least a part of the lower end with the upper surface of the fuel filter. Therefore, when the fuel moves in the storage member when the fuel tank body is inclined, a part of the fuel is blocked by the rib, so that the outflow of the fuel from the inflow hole can be particularly effectively suppressed, and the storage The amount of fuel that can be held in the member increases.

  Since at least a part of the upper end of the rib is not in contact with the lid plate portion, the fuel is spread in the storage member, and the storage member can be effectively used as a fuel storage space.

  According to a second aspect of the present invention, in the first aspect of the present invention, the entire lower end of the rib is in contact with the upper surface of the filter.

  Therefore, compared to a structure in which only a part of the lower end of the rib is in contact with the upper surface of the fuel filter, the amount of fuel that can be blocked by the rib is increased when the fuel level of the fuel tank body is inclined. .

  In invention of Claim 3, in invention of Claim 1 or Claim 2, it is non-contact with the said cover board part in the whole upper end of the said rib.

  Therefore, it is possible to distribute the fuel to the inside of the storage member in a short time compared to a structure in which a part of the upper end of the rib is in contact with the lid plate portion.

  According to a fourth aspect of the present invention, in the first aspect of the present invention, the lid plate portion is inclined so as to rise toward the inflow hole.

  In this way, when the lid plate portion is inclined so as to rise toward the inflow hole, the bubbles in the fuel stored in the storage member are raised along the inclination of the lid plate portion, and the upper side from the inflow hole. It is possible to escape and to prevent the bubbles from staying in the storage member.

  Since the present invention has the above-described configuration, even when the fuel level of the fuel tank body is inclined, the occurrence of fuel shortage can be suppressed and fuel can be reliably delivered to the outside.

It is sectional drawing. It is a partially broken top view which shows the subtank concerning 3rd Embodiment of this invention.

  1 and 2 show a schematic configuration of the fuel supply device 12 according to the first embodiment of the present invention. The fuel supply device 12 has a fuel tank body 14 in which fuel is accommodated. The fuel tank main body 14 is formed, for example, in a substantially box shape, and a fuel filter 16 is disposed therein. The fuel filter 16 allows the fuel to pass from the outside to the inside. At this time, the fuel filter 16 removes foreign matters in the fuel and prevents the foreign matters from flowing into the fuel filter 16 (for example, a woven fabric). , Non-woven fabric, porous resin, etc.). The fuel that has passed through the fuel filter 16 can be stored therein. Further, in a state where at least a part of the fuel filter 16 is immersed in the fuel in the fuel tank main body 14, an oil film LM made of fuel is formed and maintained on the surface of the fuel filter 16.

  In the present embodiment, in particular, two sheets of the same shape (for example, a polygonal shape such as a square shape, a circular shape or an oval shape may be used, but a rectangular shape as shown in FIG. 5A) are used. The non-woven fabric is joined only around these, and the upper surface filter cloth 16U and the lower surface filter cloth 16L are curved so as to protrude upward and downward, respectively. Therefore, a space for accommodating fuel is formed between the upper filter cloth 16U and the lower filter cloth 16L. In the present embodiment, the longitudinal direction of the fuel filter 16 coincides with the longitudinal direction of the fuel tank body 14. The fuel filter 16 is disposed substantially at the center of the fuel tank body 14 in plan view. The upper filter cloth 16U corresponds to the “upper surface of the fuel filter” in the present invention.

  The fuel filter 16 (particularly the lower filter cloth 16L) is disposed so as to be substantially parallel along the bottom surface 14B of the fuel tank body 14, and as shown by an arrow F1 in FIG. Can flow into the fuel filter 16. In addition, the fuel filter 16 extends along the bottom surface 14B, and even when the fuel in the fuel tank body 14 is low or biased, a part of the fuel filter 16 is more reliably attached. The state immersed in the fuel can be maintained. Of course, the material of the upper filter cloth 16U and the lower filter cloth 16L is not limited to the above-mentioned nonwoven fabric, and there is no problem even if it is a woven fabric, a sponge-like member, a mesh-like member, or the like. Further, a spacer or the like may be disposed between the upper surface filter cloth 16U and the lower surface filter cloth 16L as necessary so that these shapes (curved shapes that are convex upward or downward) can be maintained. .

  As shown in FIG. 2, the upper filter cloth 16U and the lower filter cloth 16L are made of different materials. In particular, the pressure loss of the upper filter cloth 16U is larger than the pressure loss of the lower filter cloth 16L. The material of the filter cloth is selected. The “pressure loss” here is a pressure difference before and after passage when fuel passes through the upper filter cloth 16U or the lower filter cloth 16L (for example, when a fuel pump main body 42 described later is driven). Therefore, the lower filter cloth 16L is relatively easier to pass fuel than the upper filter cloth 16U. In the present embodiment, in order to provide a difference in pressure loss as described above, the upper surface filter cloth 16U has a structure in which the total area of the voids of the nonwoven fabric is smaller than that of the lower surface filter cloth 16L.

  As can be seen from FIG. 1, a fuel pump module 32 is provided above the fuel filter 16. The fuel pump module 32 has a substantially cylindrical casing 34. The casing 34 is inserted into the fuel tank main body 14 through an attachment hole 36 formed in the upper surface 14T of the fuel tank main body 14, and a flange portion 38 that extends outward at the upper portion of the casing 34 is formed on the support portion 40 of the upper surface 14T. It is supported.

  A fuel pump main body 42 is provided inside the casing 34. A fuel suction pipe 44A extends downward from the fuel pump main body 42, and a lower end of the fuel suction pipe 44A passes through the upper surface filter cloth 16U and is opened in the fuel filter 16. A fuel discharge pipe 44 </ b> B extends upward from the fuel pump main body 42 and passes through the upper portion of the casing 34. By driving the fuel pump main body 42, the fuel is sucked through the fuel suction pipe 44A, and the fuel can be supplied to the engine (not shown) from the fuel discharge pipe 44B. The fuel delivery pipe 44 of the present embodiment includes a fuel suction pipe 44A and a fuel discharge pipe 44B.

  A storage member 18 is provided above the fuel filter 16. The storage member 18 of the present embodiment has a cylindrical side wall cylinder 20 that stands vertically from the outer edge portion of the fuel filter 16. The lower surface of the side wall cylinder 20 is joined (for example, welded) to the outer peripheral portion of the fuel filter 16. The fuel filter 16 and the storage member 18 constitute a sub tank 15.

  Further, from the upper end of the side wall cylinder 20, the cover plate portion 22 extends in a direction approaching the fuel delivery pipe 44 (a direction toward the center in plan view). In addition to the side wall cylinder 20 and the cover plate portion 22, the storage member 18 is configured by the upper surface filter cloth 16 U of the fuel filter 16. In other words, the bottom of the storage member 18 is constituted by the upper filter cloth 16U. Fuel can be stored in the storage member 18 above the fuel filter 16.

  As shown in FIG. 5A, an inflow hole 24 penetrating the lid plate portion 22 in the thickness direction is formed in the center portion (the highest position) of the lid plate portion 22. A fuel delivery pipe 44 is inserted through the central portion of the inflow hole 24. The inner dimension of the inflow hole 24 is made larger than the outer diameter of the fuel delivery pipe 44. Therefore, the hole edge of the inflow hole 24 is not in contact with the fuel delivery pipe 44, and the fuel can flow into the storage member 18 through these gaps 28. Since the inflow hole 24 also serves as an insertion hole for inserting the fuel delivery pipe 44, it is not necessary to form such an insertion hole again, and the structure is simplified.

  The cover plate portion 22 is inclined so as to rise from the outer peripheral portion toward the center portion (portion where the inflow hole 24 is formed). By having such an inclination, in the state where the inside of the storage member 18 is filled with fuel, the bubbles present in the fuel rise along the lower surface of the cover plate portion 22 and come out of the storage member 18. .

  The height of the storage member 18 is set such that the position in the height direction of the uppermost portion 18T (portion where the inflow hole 24 is formed) is lower than the liquid level notification position WL set in the fuel tank body 14. ing. This notification position WL is a reference position for notifying the occupant that the remaining amount of fuel has decreased when the fuel level is detected by a liquid level sensor (not shown) and the position is below the notification position WL. . That is, even if the liquid level in the fuel tank main body 14 is lower than the notification position WL, the position of the inflow hole 24 of the storage member 18 is such that the fuel flows into the storage member 18 through the inflow hole 24. It has been decided.

  In the present embodiment, in particular, the joining piece 26 is formed in the lower portion of the side wall cylinder 20. The joining piece 26 increases the joining area between the side wall cylinder 20 and the fuel filter 16 to improve the joining strength, and upwards the fuel filter 16 when the fuel flows into the fuel filter 16 through the lower filter cloth 16L. It has the effect of suppressing movement. The joining piece 26 may be omitted.

  A plurality of ribs 46 are erected upward from the upper filter cloth 16U. As shown in FIG. 5 (A), each of the ribs 46 is formed in a plate shape extending along the short direction of the sub tank 15, and the entire lower side (lower end) of the rib 46 is a top filter cloth. It is in contact with 16U. On the other hand, the entire upper side (upper end) of the rib 46 is separated from the lid plate portion 22, and the rib 46 is formed so that a predetermined gap 50 (see FIG. 2) is formed between the rib 46 and the lid plate portion 22. The height of is decided. In the present embodiment, since the lid plate portion 22 is inclined, the height of the rib 46 also varies depending on the position.

  As shown in detail in FIGS. 5A and 5B, the plurality of ribs 46 are arranged in parallel and are held by a holding frame 48. A joining flange 48F formed on the outer peripheral portion of the holding frame 48 is joined to the joining piece 26 over the entire circumference.

  Next, the operation of the fuel supply device 12 of this embodiment will be described.

  As shown in FIG. 1, in the state where fuel is present in the fuel tank main body 14 at a higher liquid level than the inflow hole 24 of the storage member 18, the gap 28 (between the inflow hole 24 and the fuel delivery pipe 44). The fuel that has flowed in is stored in the storage member 18. In this state, fuel is also present in the fuel filter 16.

  Here, when the fuel pump module 32 is driven, the fuel in the fuel filter 16 is sent to the outside (engine or the like) through the fuel delivery pipe 44 as indicated by an arrow F0. Fuel can flow into the fuel filter 16 through the upper filter cloth 16U (see arrow F2) and the lower filter cloth 16L (see arrow F1). In particular, the pressure loss of the lower filter cloth 16L is caused by the upper filter cloth 16L. Since the pressure loss is lower (smaller) than the pressure loss of the cloth 16U, more fuel substantially passes through the lower filter cloth 16L and flows into the fuel filter 16. Further, the fuel in the fuel tank main body 14 flows into the storage member 18 through the gap 28 as indicated by an arrow F3.

  Even when the amount of fuel in the fuel tank main body 14 is small, if at least a part of the fuel filter 16 (in this embodiment, the lower filter cloth 16L) is immersed in the fuel, the surface of the fuel filter 16 has a fuel. The oil film LM is formed and maintained.

  When the fuel tank main body 14 is inclined due to the vehicle running on a slope, or when G acts on the fuel tank main body 14 during acceleration / deceleration, turning, etc., as shown in FIG. Liquid level fluctuations may occur that are biased toward one side and the liquid level is inclined (when the fuel liquid level is inclined).

  At this time, as can be seen from FIG. 3, the fuel filter 16 is exposed in the gas in the fuel tank body 14 above the liquid level, but the portion below the liquid level is immersed in the fuel. If so, the oil film LM on the surface is maintained. The energy required for fuel delivery depends on the surface tension of the oil film.

(Gas suction from the gas phase)> (Fuel suction from the liquid phase)

Therefore, only the fuel is sucked into the fuel filter 16. In these states, the fuel in the fuel filter 16 can be sent to the outside by driving the fuel pump module 32.

  Moreover, in the fuel supply device 12 of the present embodiment, the rib 46 is erected in the storage member 18, and the entire lower side of the rib 46 is in contact with the upper surface filter cloth 16U. Therefore, as can be seen from FIG. 3, when the fuel level inclines in the longitudinal direction of the fuel tank body 14, in the storage member 18, the region in the direction (arrow G direction) in which the fuel has moved from the inflow hole 24 (in FIG. 3). Not only the left region) but also the opposite region (the right region in FIG. 3), the fuel that is about to flow in this moving direction is blocked between each of the ribs 46 and the upper filter cloth 16U. Can be held. That is, more fuel can be stored in the storage member 18 than in the configuration in which the rib 46 is not provided. Moreover, since the fuel held and held by each of the ribs 46 comes into contact with the upper surface filter cloth 16U, the contact area of the fuel with respect to the upper surface filter cloth 16U increases.

  Furthermore, as shown in FIG. 4, a state is considered in which the fuel in the fuel tank main body 14 is reduced and the fuel level of the fuel tank main body 14 is inclined. In this case, the fuel in the fuel tank main body 14 (fuel outside the storage member 18) has been separated from the fuel filter 16. However, in the present embodiment, in the storage member 18 above the fuel filter 16, the fuel is stored in the region in the direction in which the fuel moves from the inflow hole 24 (the left region in FIG. 4). The bottom part of 18 is comprised by the upper surface filter cloth 16U of the fuel filter 16. FIG. That is, since a part of the fuel filter 16 is immersed in the fuel, the oil film LM formed on the surface of the fuel filter 16 is continuously maintained. Therefore, the fuel in the storage member 18 flows into the fuel filter 16. In this case as well, as in the state shown in FIG. 3, the energy required for sending the fuel depends on the surface tension of the oil film.

(Gas suction from the gas phase)> (Fuel suction from the liquid phase)

Therefore, the fuel in the storage member 18 is sucked into the fuel filter 16 as indicated by the arrow F2. Moreover, even in this state, in the region opposite to the fuel moving direction from the inflow hole 24 (the region on the right side in FIG. 4), the flow flows in the moving direction between each of the ribs 46 and the upper filter cloth 16U. The fuel to be dammed can be held and held. The fuel in the fuel filter 16 can be sent to the outside by driving the fuel pump module 32. Substantially all of the fuel in fuel filter 16 and reservoir 18 can be delivered.

  As described above, in the fuel supply device 12 of the present embodiment, by providing the rib 46, it is possible to store more fuel in the storage member 18 provided above the fuel filter 16, and the fuel tank Even when the fuel level of the main body 14 is inclined, the occurrence of so-called fuel shortage is suppressed, and the fuel can be reliably delivered to the outside.

  In particular, since a service hall is formed in the body panel above the fuel pump module 32 and the sub tank 15 is mounted in the fuel tank body 14 through the service hole, the sub tank 15 ( There are limitations on the width and length of the fuel filter 16 and the storage member 18). However, even if the size of the sub tank 15 is limited in this way, it is possible to secure a large amount of fuel that can be stored in the storage member 18 when the fuel level of the fuel tank body 14 is inclined.

  In addition, the height of each rib 46 is determined in relation to the lid plate portion 22 so that the entire upper side of the rib 46 is separated from the lid plate portion 22. A gap 50 is formed between them. For this reason, when returning to the horizontal state shown in FIG. 1 or the like, the rib 46 does not restrict the fuel that has flowed into the storage member 18 from the inflow hole 24 into the storage member 18. That is, fuel can be distributed to the inside (whole) of the storage member 18 in a short time.

  In the above description, the rib 46 is extended along the short direction of the sub tank 15. However, as can be seen from the above description, when the fuel level of the fuel tank body 14 is inclined, the storage member 18. The direction of the rib 46 may be determined so that the direction in which the amount of stored fuel in the interior is to be increased is the direction perpendicular to the extending direction of the rib 46. For example, when the rib 46 extends along the longitudinal direction of the sub tank 15, more fuel can be stored in the sub tank 15 when the fuel liquid level is inclined in the longitudinal direction of the sub tank 15.

  6A to 6C show a sub tank 65 constituting the fuel supply device of the second embodiment of the present invention. In the fuel supply device of the second embodiment, only the structure of the subtank is different from that of the first embodiment, but the other parts are the same, so only the subtank 65 of the second embodiment will be described below. The description of the overall configuration of the fuel supply device of the second embodiment is omitted.

  The sub tank 65 of the second embodiment includes the fuel filter 16 and the storage member 18 similar to those of the first embodiment. However, the storage member 18 has a short side extending in the short direction of the sub tank 65. The ribs 66S and the longitudinal ribs 66L extending in the longitudinal direction are arranged to form a lattice-like rib 66 as a whole. The lower side of the short rib 66S and the lower side of the long rib 66L are in contact with the upper surface filter cloth 16U, but the upper side of the short rib 66S and the upper side of the long rib 66L are separated from the cover plate portion 22 and the gap 50 Is configured.

  In the fuel supply device of the second embodiment configured as described above, as shown in FIG. 6 (B), not only the case where the fuel liquid level is inclined in the longitudinal direction of the sub-tank 65, but also in FIG. 6 (C). As shown, even when the fuel liquid level is inclined in the short direction of the sub tank 65, more fuel can be stored in the storage member 18. Further, even when the fuel level is inclined in the oblique direction of the sub tank 65 (the direction in which the longitudinal direction and the short direction are combined), more fuel can be stored in the storage member 18.

  FIG. 7 shows a sub tank 85 constituting the fuel supply apparatus according to the third embodiment of the present invention. Also in the fuel supply device of the third embodiment, only the structure of the subtank is different from that of the first embodiment, but the other components are the same, so only the subtank 85 of the third embodiment will be described below. The description of the overall configuration of the fuel supply device of the third embodiment will be omitted.

  The sub tank 85 of the third embodiment includes the fuel filter 16 and the storage member 18 similar to those of the first embodiment. However, a plurality of substantially U-shaped ribs 86 are provided inside the storage member 18 in plan view. (In FIG. 7, a total of 12 rows are arranged in 4 rows in the longitudinal direction and 3 rows in the short direction). Each of the ribs 86 is disposed such that the open portion 86 </ b> R faces the outside in the longitudinal direction of the sub tank 85. In addition, the rib 86 according to the third embodiment also has the entire lower side in contact with the upper filter cloth 16U, but the upper side is separated from the cover plate portion 22, and a gap 50 is formed (first embodiment). FIG. 2 shown as a form). The plurality of ribs 86 are held at predetermined positions by a flat holding plate 88. And it is joined to the joining piece 26 (refer FIG. 1) over the perimeter by the joining flange 88F of the outer peripheral part of the holding | maintenance board 88. FIG.

  In the fuel supply device of the third embodiment having such a configuration, when the fuel liquid level is inclined in the longitudinal direction of the sub tank 85, the inside of the rib 86 positioned above the inflow hole 24 and the upper filter cloth 16U. Therefore, more fuel can be stored in the storage member 18.

  In the above example, the entire lower side (lower end) of each rib (ribs 46, 66, 86) is in contact with the upper surface filter cloth 16U, but at least a part of the lower side is an upper surface filter cloth 16U. If it is in contact with the fuel tank, the contact portion has an effect of blocking the fuel when the fuel level of the sub tank is inclined. When all of the lower sides of the rib are in contact with the upper filter cloth 16U as in the above embodiment, the effect of blocking the fuel is high.

  In the above example, the entire upper side (upper end) of the rib is separated from the cover plate part 22. However, if at least a part of the upper side is separated from the cover plate part 22, the separated part is provided. A gap is formed. Therefore, the fuel that has flowed into the storage member 18 from the inflow hole 24 can be spread through this gap. If all of the upper sides of the ribs are not in contact with the cover plate part 22 as in the above embodiment, the fuel can be spread into the storage member 18 in a shorter time.

  The specific structure in which the rib 46 is disposed in the storage member 18 is not particularly limited. For example, the plurality of ribs 46 may be simply placed on the upper surface filter cloth 16U. However, if the ribs 46 are fixed to the upper surface filter cloth 16U by bonding or welding, the positional deviation of the ribs 46 can be suppressed. Even if a joint portion such as a joint flange is provided on the holding frame 48 around the rib 46 as in the upper embodiment, the positional deviation of the rib 46 can be suppressed.

  In the above, an example in which the cover plate portion 22 of the storage member 18 is inclined so as to rise from the outer peripheral portion toward the center portion (portion where the inflow hole 24 is formed) has been described. It may be formed in a flat plate shape without being inclined, or may be configured to be inclined so as to descend from the outer peripheral portion toward the central portion so that fuel flows into the inflow hole 24 by gravity.

  Furthermore, the relationship between the storage member 18 and the delivery means (the fuel pump module 32, particularly the fuel suction pipe 44A) is not limited to that described above. For example, the fuel suction pipe 44 </ b> A may be configured to penetrate the lid plate portion 22 at a position different from the inflow hole 24 of the lid plate portion 22.

  Further, the storage member 18 may not cover a part of the fuel filter 16 (a part of the fuel filter 16 protrudes outward from the storage member 18 when viewed from above). In this case, if the fuel suction pipe 44 </ b> A is connected to the protruding portion of the fuel filter 16 (outside the storage member 18), a structure that does not penetrate the cover plate portion 22 can be achieved.
