Embodiment
Below in conjunction with identical accompanying drawing, simultaneously to according to fuel filter seat of the present utility model and comprise that the fuel filter of this fuel filter seat is described.
As shown in Figure 1, among first embodiment of the present utility model, the oil-feed side of fuel filter seat 1 has filler opening 18 and oil suction chamber 19, and the clean side of filter cleaner 1 has the back of filtration oil pocket 23, oil outlet 25, and the clean side of filter cleaner 1 also is integrated with bypass type hand oil pump 2.
Fuel oil fitering element is connected the downside of filter cleaner 1.Fuel oil fitering element comprises lower shell body 1, filter paper core 4 and center tube 22, and lower shell body 3 is connected with the downside of filter cleaner 1 by screw connection structure 6, is provided with seal element 5 in screw connection structure 6, and seal element 5 for example is an O-ring seals.Lower shell body 3 provides a filter core oil pocket 20, enters into filter core oil pocket 20 again after the fuel oil that enters from filler opening 18 enters into oil suction chamber 19, and filter paper core 4 and center tube 22 are supported in the filter core oil pocket 20 by supporting structure 90.The top and bottom of filter paper core 4 all seal, and fuel oil can only see through from the outside of the sidewall of filter paper core 4, and center tube 22 is arranged on the center of filter paper core 4, make that the fuel oil in the filter core oil pocket 20 has only through just entering into center tube 22 after the filter paper core 4.Center tube 22 and filter back oil pocket 23 and communicate is tightly connected by link 7 and filter cleaner 1 at the end near filtering back oil pocket 23 of center tube 22 and filter paper core 4, filters back oil pocket 23 so that have only fuel oil through filter paper core 4 just can enter into.
As shown in Figure 2, second embodiment of the present utility model is that with first embodiment's difference the structure of fuel oil fitering element is different, in a second embodiment, fuel oil fitering element is a kind of rotation fitting type filter core 30, comprise lower shell body 3, filter paper core 4 and center tube 34, the upper end cap of lower shell body 3 is provided with link 71, and link 71 is threaded with fuel filter seat 1.Lower shell body 3 provides filter core oil pocket 20, and filter core oil pocket 20 and oil suction chamber 19 are communicated with, and fuel oil enters into oil suction chamber 19 from filler opening 18, enter into filter core oil pocket 20 then.The upper-end surface of lower shell body 3 is embedded with outside seal may 32, at lower shell body 3 with after fuel filter seat 1 is connected, outside seal may 32 just separates the inner chamber and the external world that extraneous and fuel filter seat 1, lower shell body 3 form, also be provided with inner seal liner 31 at filter paper core 23 with after filtering between the oil pocket 23, so that have only fuel oil just can enter into filtration back oil pocket through filter paper core 4, the top and bottom of filter paper core 4 also are sealed in fact, and the fuel oil in the filter core oil pocket 20 has only the outside through the sidewall of filter paper core 4 could see through filter paper core 4 to enter into center tube 34.Center tube 34 is arranged on the center of filter paper core 4, and has only through fuel oil filter paper core 4, in the filter core oil pocket 20 and just can enter into center tube 34.Filter paper core 4 and center tube 34 are supported by supported spring 35.The maximum of first embodiment and second embodiment's fuel oil fitering element is not both, lower shell body 3 can directly be pulled down from fuel filter seat 1 in first embodiment, filter paper core 4 and center tube 22 also can directly be replaced then, and in a second embodiment, lower shell body 3 and filter paper core 4 can only be replaced simultaneously.
Fig. 1 can be identical structure with the bypass type hand oil pump 2 shown in Fig. 2.Bypass type hand oil pump 2 comprises hand pump fixed cover 10, hand pump enclosing cover 11, seal membrane 12 and hand pump travel(l)ing rest 13, hand pump fixed cover 10 is fixed on the fuel filter seat 1, hand pump enclosing cover 10 is spacing by hand pump fixed cover 10, hand pump travel(l)ing rest 13 is enclosed within on the directional post 15 of fuel filter seat 1 movably, seal membrane 12 parts are clamped between hand pump enclosing cover 11 and the hand pump travel(l)ing rest 13, a part is clamped between hand pump fixed cover 10 and the fuel filter seat 1, thereby seal membrane 12 separates the oil pocket and the external world of bypass type hand oil pump 2.Also be provided with Returnning spring 14 between hand pump travel(l)ing rest 13 and fuel filter seat 1, after hand pump enclosing cover 11 was pressed, hand pump travel(l)ing rest 13 moved along directional post 15, and when seal membrane 12 all can be separated by the oil pocket and the external world of oil pump 2.After discharging hand pump enclosing cover 11, because hand pump fixed cover 10 is spacing, hand pump enclosing cover 11 returns back to the home position under the effect of the elastic force of Returnning spring 14.
Between the path of the oil pocket of bypass type hand oil pump 2 and filtration back oil pocket 23 one-way valve 17 is set, between the oil pocket of bypass type hand oil pump 2 and the path of oil outlet 25 one-way valve 26 is set, between the path of oil outlet 25 and filtration back oil pocket 23 one-way valve 24 is set.
In use, by constantly pushing bypass type hand oil pump 2 repeatedly, fuel oil can be sucked in fuel filter seat 1 and the whole oil-fired system, and gas inside is discharged.When hand oil pump was pressed, fuel oil or gas oil pocket 16 in the hand oil pump directly entered oil outlet 76 by one-way valve 26, and this moment, first one-way valve 24 and second one-way valve 17 were closed.Under the effect of Returnning spring 14, hand oil pump automatically resets and pops up, produce negative pressure in the oil pocket 16 at this moment, the pulling fuel oil sucks (this moment, one-way valve 17 was opened) from filler opening 18, see through filter paper core 4 and enter filtration back oil pocket 23, enter oil pocket 16 in the hand oil pump by one-way valve 17, this moment, one-way valve 24 and one-way valve 26 were closed.When automobile engine starting, oil outlet 25 is in the state of negative pressure oil suction, so fuel oil sucks, enters oil suction chamber 19, filter core oil pocket 20 from filler opening 18, see through filter paper core 4 and enter and filter back oil pocket 23, and enter oil outlet 25 and without hand oil pump 2 by one-way valve 24 direct bypass; At this moment, one-way valve 17, one-way valve 26 are in closing state substantially.As can be seen, in aforesaid process, the oil that enters into bypass type hand oil pump 2 must pass through filter paper core 4, and therefore dirty fuel oil can not enter into bypass type hand oil pump 2 and make that bypass type hand oil pump 2 is blocked.
Aforesaid filter paper core 4 should be understood to the various filter cores that fuel oil filters that are used for, for example it is also understood that into the copper filter screen, also there is multiple modification in the structure of aforesaid fuel oil fitering element, even can select commercially available fuel oil fitering element to be connected with fuel filter seat of the present utility model, to be combined into fuel filter of the present utility model.Though the utility model discloses as above with preferred embodiment, yet it is not in order to limit the utility model, anyly be familiar with one of ordinary skill in the art, in not breaking away from spirit and scope of the present utility model, should make the variation or the replacement of all equivalences.Therefore, protection domain of the present utility model is as the criterion when looking accompanying the scope that the application's claim defined.
