In the position that the first framework 33a and the second framework 34a report to the leadship after accomplishing a task, except above-mentioned joint 31a be connected the position the 32a of portion, be provided with the outstanding frame rib 35a to hypopleurite material part 23b.Equate from the overhang of the outstanding frame rib 35a in the back side of the first framework component parts 25a joint 31a outstanding with the back side from the first framework component parts 25a and the overhang that is connected the 32a of portion.And, these joints 31a, being connected the internal surface butt of the 32a of portion and frame rib 35a and filter element 24, they are by pushing the internal surface of filter element 24 to keep the interval of underframe 30a and downside sheet material part 23b to the outside of filter element 24.
In addition, underframe 30a has the inside and the outside interconnecting part 36 being communicated with that make filter element by means of connector element 22.Interconnecting part 36 has: by the roughly lip portions 37 cylindraceous of the first framework 33a and the second framework 34a support, the roughly sucting 38 cylindraceous extending to the direction contrary with said frame rib 35a from lip portions 37.In addition, on interconnecting part 36, at the circumferencial direction of lip portions 37 uniformly-spaced to dispose from lip portions 37 to four side-prominent ribs 39 for suction of hypopleurite material part 23b.And, use the internal surface butt of rib 39 and filter element 24 by suction, thereby keep the interval of lip portions 37 and downside sheet material part 23b, and can suppress sucting 38 and be stopped up by downside sheet material part 23b.
As shown in Figure 7, the first framework component parts 25a is configured in the inside of filter element 24 in the following manner: a part for lip portions 37 is exposed to the outside of upside sheet material part 23a by through hole 40, and sucting 38 protrudes from the outside of filter element 24 by this through hole 40.And the underpart 46 of connector element 22 is connected with interconnecting part 36, and the upper end portion 47 of connector element 22 is connected with petrolift 13.On connector element 22, be formed with service channel 45 in the mode connecting from 46Dao upper end portion, underpart 47.Sucting 38 is inserted to underpart 46 sides of this service channel 45.In addition, the underpart 46 of connector element 22 is connected with lip portions 37, to clamp upside sheet material part 23a by this underpart 46 with lip portions 37.And in the time that petrolift 13 is worked, the fuel F that flows into sucting 38 is imported in petrolift 13 by service channel 45.
According to the filter 21 of such formation, in the time that petrolift 13 is worked, become negative pressure state as the storage area 43 in the space in filter element 24.And, when storage area 43 is during in negative pressure state, the outside pushing to filter 21 by upside sheet material part 23a by underframe 30a itself.In addition, the now also outside pushing to filter 21 by downside sheet material part 23b with rib 39 by frame rib 35a and suction.Therefore, kept the interval of upside sheet material part 23a and downside sheet material part 23b, thereby be formed with storage area 43 with the size of being scheduled between upside sheet material part 23a and downside sheet material part 23b.And, by roughly all just flowing in sucting 38 by such storage area 43 with the fuel F roughly all filtering of downside sheet material part 23b of upside sheet material part 23a.
The structure of the second framework component parts 25b is described below.In addition, the second framework component parts 25b is not having interconnecting part 36 and is sucking with different from the first framework component parts 25a on rib 39 these aspects.On the other hand, relevant other structure, the second framework component parts 25b is substantially identical with the first framework component parts 25a.Therefore, for the second framework component parts 25b, main explanation and the first framework component parts 25a difference.
As shown in Fig. 8 (a), Fig. 8 (b), the second framework component parts 25b has the underframe 30b as cancellate plate.Underframe 30b forms by multiple the first framework 33b that extend to direction with orthogonal multiple the second framework 34b of this first framework 33b.The peripheral part of underframe 30b is made up of the second framework 34b of mutually relative a pair of the first framework 33b and the mutual relative a pair of edge part of conduct.A side at mutually relative a pair of the second framework 34b is formed with joint 31b, and is formed with and is connected the 32b of portion the opposing party.
On joint 31b, be formed with by thering is with clamping part 31aj the clamping part 31bj that same structure forms.In addition, be connected on the 32b of portion, be formed with by thering is with the portion 32aj of being held the 32bj of the portion that is held that same structure forms.And, being held the 31aj of portion, 31bj when clamping when being held the 32aj of portion, 32bj, two framework component parts 25a, 25b can connect agley in interconnective part.
In addition, the length of the second framework 34a, the 34b of formation joint 31a, 31b is identical with the length that forms the second framework 34a, the 34b that are connected the 32a of portion, 32b.According to this structure, in the time connecting the first framework component parts 25a and the second framework component parts 25b, the outer rectangle that is formed as of support frame 25.And, consistent with the profile of support frame 25, the profile of upside sheet material part 23a and downside sheet material part 23b is also done orthogonal.Its result, can make simple shape by the profile of filter 21.In addition, make rectangle owing to cutting can being filtered to the needed cut-out mould of sheet material 23, thereby can realize the reduction of cutting off the costs such as mould maintenance cost.
The situation that each framework component parts 25a, 25b connect is described below.In addition, the situation being connected between situation and two second framework component parts 25b of the first framework component parts 25a and the connection of the second framework component parts 25b is identical.Therefore, below, only the situation of the connection between two the second framework component parts 25b is described.
As shown in Fig. 9 (a), by clamping part 31bj clamping be held the 32bj of portion and by joint 31b be connected the 32b of portion and link together.At this, to observe with being connected the direction that the 32b of portion extends from joint 31b, the curvature of ratio of curvature clamping part 31bj that is held the 32bj of portion is slightly little.Therefore,, in the time that two the second framework component parts 25b are subject in attachment portion wanting bending power, are held the 32bj of portion and slide in clamping part 31bj along with this power.Then, two the second framework component parts 25b are bending swimmingly in attachment portion.In addition, observe with being connected the direction that the 32b of portion extends from joint 31b, joint 31b and the section configuration that is connected the 32b of portion are C font roughly, therefore, even if the connection of two the second framework component parts 25b is also difficult to be disengaged in the time of their bendings.
At this moment, equate from the outstanding joint 31b in the back side of the second framework component parts 25b and the overhang that is connected the frame rib 35b that the overhang of the 32b of portion is outstanding with the back side from the second framework component parts 25b.The overhang of such frame rib 35b is for fuel F is in the interior necessary size that flows of filter element 24, in the present embodiment, is set as minimum value.At this, in the structure as filter element 24, the surface of this structure and the interval at the back side are larger, and conventionally, this structure of bending is just more difficult.In this, according to said structure, be the little overhang consistent with each other with the overhang of frame rib 35b owing to being held the overhang of the 32bj of portion and clamping part 31bj, can accomplish to take into account guarantee storage area 43 with improve fuel filter 20 sheathed the two.
In addition, when fuel filter 20 is during from the further bending of state shown in Fig. 9 (a), Fig. 9 (b), joint 31b, be connected the 32b of portion and frame rib 35b just contacts with downside sheet material part 23b.At this moment, due to joint 31b and be connected the 32b of portion and form intermittently along the second framework 34b, thereby storage area 43 is just by connecting communicatively between adjacent joint 31b and between the adjacent 32b of the portion that is connected., even in the time that joint 31b and the portion 32b of being connected are closely sealed with downside sheet material part 23b, also can form continuously storage area 43 within the scope of the whole length direction of fuel filter 20.
As described above, according to the fuel filter of present embodiment, can obtain the effect of the following stated.
(1) be held the 32aj of portion, 32bj be held the 31aj of portion, 31bj clamping mode each framework component parts 25a, 25b are linked together.Therefore, can make support frame 25 bending swimmingly at framework component parts 25a, 25b joint each other.In addition, owing to need to not be formed for inserting the hole that pin is set on each framework component parts 25a, 25b, thereby can be by reduced thickness own support frame 25.Therefore, can accomplish to take into account guarantee in the inside of filter element 24 the mobile runner of fuel F with improve filter element 24 sheathed the two.
(2), owing to being held the 32aj of portion, 32bj and clamping part 31aj, 31bj running fit, and by being held compared with the 32aj of portion, 32bj make closely sealed structure with clamping part 31bj, can alleviate the needed load of bending fuel filter 20.
(3) clamping part 31aj, 31bj and be held the 32aj of portion, 32bj and form intermittently along the second framework 34a, 34b respectively.Therefore, even at joint 31a, 31b and be connected the 32a of portion, 32b and when downside sheet material part 23b is closely sealed, in the attachment portion of each framework component parts 25a, 25b, also can guarantee gap between filter element 24 and framework component parts 25a, 25b.
(4) only on the first framework component parts 25a, formed interconnecting part 36.Therefore,, by changing the quantity of each framework component parts 25a, 25b and putting in order, just can change the position of the interconnecting part 36 of fuel filter 20.In addition, can also not use the new die that be shaped each framework component parts 25a, 25b use just to form the fuel filter 20 consistent with the shape of petrolift 13 and the shape of fuel tank 11.
(5) each framework component parts 25a, 25b have the multiple through holes that penetrate into the back side from its surface.Therefore, the surface side of support frame 25 is communicated with by through hole with the back side of support frame 25.Thus, being taken into the fuel F after filtering of filter 21 inside just can be by above-mentioned through hole in the roughly interior circulation of whole filter element 24.Its result, because fuel F after filtering improves in the mobility of the inside of fuel filter 20, thereby can reduce the load of petrolift 13.And, can suppress the increase of the electric weight that petrolift 13 consumes.
