In the example, passage 312 comprises the side opening 314 that is communicated with passage 312 fluids.Side opening 314 is so that the fluid after filtering can leave separator 300 and end plate 302.

Among the embodiment, two passages 318 are arranged.In the example, the second mobile part 306 comprises at least one side opening 316, for example is used for the side opening of each passage 318.Two side openings 316 shown in the figure are if but should be understood that if suitablely for example have two with upper channel 318 plural side opening can be arranged.Side opening 316 is communicated with its passage 318 fluids separately, and flow is inducted into the side of the second mobile part 306 and is inducted into passage 318.Flow is introduced the second mobile part 306 from each side of filter core and/or the edge of end plate 302.Should be understood that if side opening 316 and passage 318 are used as entrance, then flow will enter the passage 318 of separator 10 and flow out towards each side of filter core and/or the edge of end plate 302 from side opening 316.

Separator 300 can include sealing function, for example, and when the filter core that connects when end plate 302 is connected to the receiving portion of filter assemblies.In the example, groove 308 and groove 310 are separately positioned on the second mobile part 306.Each can have the seal that is arranged in each groove in the groove 308,310, such as but not limited to O shape ring or gasket-type seal.For example, the seal in the groove 308,310 sealing will be left after the filtration of side opening 314 exhaust fluid of fluid and the work exhaust stack 338 of leaving channel 318 and filter assemblies and seal and open.Referring to Figure 26.Among some embodiment, the first mobile part 304 comprises the stopper 320 with groove 330, and groove is used for arranging seal.Stopper 320 for example can clog the maintenance delivery pipe 340 of filter assemblies in engine operation process and when filter core is installed.When filter core was removed, stopper 320 was removed and seals and is released, thereby the fluid that is retained in the filter assemblies can be discharged from, and can maintain and/or renew cartridge more.

Will also be understood that, groove 308,310 and 330, the first the flow outer surface of part 306 or the edge of parts 304 and second that flow for example can be configured to hermetic unit and not need extra seal by each surperficial interference fit or interference fit to the admittance separator 300 of filter assemblies as an alternative.

With further reference to Figure 26, fluid flow path can be so that the water that the fluid of discharging for example separates from fuel oil enter second flow part 306 side opening 316 and flow through passage 318 and exhaust stack 338 outflow separator 300 and the end plates 302 by work.Fluid after the filtration for example fuel oil leaves by end plate 302 after being filtered by filter medium 322 and flows through passage 312 and leave and flow to the outlet 334 of filter assemblies by side opening 314, for example the fuel oil filter housing.Stopper 320 clogged maintenance delivery pipe 340 always before filter core is removed.

Figure 27 illustrates separator 300 and the end plate 302 of a minor change, and it is connected to the part of twin-stage (perhaps being provided with the filter form in the filter) filter, and this double filter has first order medium 422 and second level medium 424.Fluid flow path is similar to the fluid flow path in the filter core of Figure 25-26, has adopted the flow behavior of separator 300 in this fluid flow path, for example at the fluid that will filter by after the first order 422.The minor change of separator 300 and end plate 302 is to include depression 301, and depression 310 is held the central tube of second level medium 424.

Figure 28 is the cutaway view for another embodiment of the separator 500 of filter core end plate.Shown separator 500 and end plate are to connect into the part of filter core and be connected to filter assemblies.Figure 28 also illustrates the fluid flow path by separator 500 and end plate.Be similar to Figure 27, filter core is another example of the filter core of twin-stage (or being provided with filter in the filter) type with first order medium 522 and second level medium 524.Be that with the difference of Figure 27 second level medium 524 is shorter than first order medium 522.In order to hold the different big or small filter medium of filter core, tip plate configurations changes over respectively two plates 502,503 structures that connect at every grade of medium 522,524 place, end.Between plate 502,503, side opening 516 is communicated with passage 518 fluids, and this can be so that fluid for example can be discharged filter core, separator 500 and end construction from the water that fuel oil separates.Fluid can all leave admission passage 512 and outflow side opening 514 by plate 502,503 after filtering.Fluid flow path except for the differing heights (or length) that adapts to two-stage medium 522,524 modification to tip plate configurations (two plate 502,503), is similar to shown in Figure 27.

The utility model can otherwise be implemented and not break away from spirit of the present utility model and character of innovation thereof.The application's the disclosed embodiments all are considered to illustrative rather than restrictive in all respects.Scope of the present utility model is indicated by the description of appended claims rather than front; And being included in the implication that is equal to of claims and all changes in the scope all should be comprised in the scope of the present utility model.
