Definitions
- the invention relates to a filter system for fuel in particular for
- Diesel filter wherein a particulate filter is provided in a housing, according to the preamble of independent claim 1.
- a fuel filter can be seen.
- This has a housing in which a main filter element and a second filter element are provided.
- the main filter element is flowed through from the inside to the outside.
- this coalescing properties so that possibly present in the fuel water is coalesced, d. H. form larger drops of water. These get into a water collection room.
- the filter element is provided with water-repellent materials, in particular silicone, so that an outer water barrier is formed.
- Both the first filter element and the second filter element consists of a folded filter paper or filter fleece.
- the second filter element While the flow through the first filter element from the inside to the outside, the second filter element is flowed through from outside to inside and fed the purified fuel in a pipe of a clean liquid line.
- a disadvantage of this structure is that the main filter element is loaded with dirt due to its filter-effective properties and this dirt reduces or obstructs the flow.
- the main filter element loses its properties as a coalescer over time, this means that overall the filter system loses its water-separating properties or this water separation deteriorates until replacement of the filter element.
- the invention has for its object to avoid the disadvantages mentioned and to provide a filter system for fuels, which ensures a highly effective deposition over the entire service life of the filter element and is easy to manufacture.
- PatXML 2/9 2361
- the essential advantage of the invention lies in the fact that the coalescing element is constructed in a simple manner, wherein in particular the sealing or end plate necessary for sealing is formed integrally and extends up to a wall of the housing. This eliminates another sealing element.
- the end plate consists of a two-component plastic material, wherein the first component is a conventional thermoplastic and the second component is an elastomer. This second component takes over the seal on the wall of the housing.
- a sealing ring or a molded seal can also be used, wherein this sealing ring or the molded seal is arranged in the radially outer region of the end plate and in any case lies outside the effective coalescing surface.
- a further embodiment of the invention provides to arrange the inflow opening for the liquid on the housing and the inflow opening for the liquid at the end plate of the coalescer in alignment, d. H. the liquid undergoes no flow reversal when flowing. This has the advantage that, if water droplets have already formed in the liquid, they are not destroyed or split by deflecting edges or deflection surfaces.
- this is done axially, d. H.
- a profile seal or a molded seal is arranged in the direction of the inflow opening.
- the fixation of both the Coalescerelements, as well as the filter element is basically a spring washer, which is supported on the one hand at the bottom of the housing and on the other hand exerts an axially directed force on the filter element.
- This spring element takes over both the radial guide on one side of the filter element, as well as the axial position positioning.
- a Wasserammeiraum is arranged on the housing bottom, this is provided with an opening or a drain valve for discharging the water. Furthermore, a heater and / or a water sensor can be provided in this area.
- the Wasserammeiraum itself is integrated into the housing, but it is possible to screw on the downwardly open housing an existing example of transparent plastic material pot.
- the coalescing element is preferably made of a hydrophobic material.
- the downstream particle filter may likewise have an outer layer of hydrophobic material, for example of fabric, meltblue or nonwoven.
- FIG. 1 shows a half-sectional view of a fuel filter in a schematic form
- FIG. 2 is an enlarged view of the inflow area of a fuel filter.
- a fuel filter according to Figure 1 consists of a housing 10, which is designed substantially cup-shaped.
- the housing is closed at the top by a lid 11, this cover has inlet openings 12 for the inflow of the fuel, in which case one of the inlet openings is shown.
- These inlet openings are designed on a pitch circle as holes and evenly distributed.
- an outlet opening 13 is provided, from which the purified fuel can be removed.
- a water discharge valve 14 At the lower end of the housing 10 is a water discharge valve 14, which is shown here only schematically.
- Within the housing is a riser 17th
- a particulate filter 19 In the housing 10 is a particulate filter 19, this consists of a zigzag-shaped folded filter material, which may be constructed, for example, multi-layered. Above the particle filter 19, a coalescing element 20 is arranged. In the example shown, this also consists of a zig-zag folded medium.
- This medium can be a polyester material, a polyamide or other material with coalescing properties for water.
- the particle filter 19 has on the inner wall of a St ⁇ tzrohr 15, which is provided with openings, so that the purified liquid can pass unhindered in the central region and flows through the riser 17.
- the medium to be cleaned flows, such as diesel fuel and flows through according to the arrow 22, the coalescer 20 from the inside to the outside.
- the water that is in the fuel coalesces into large accumulations or droplets, flows down the housing wall 10 and collects within a water reservoir 23.
- the fuel to be purified flows from outside to inside according to the arrow 24 through the filter element , is cleaned there and leaves via the riser 17 and the outlet opening 13, the filter system. If water has accumulated in the water reservoir 23 up to a certain level, it can be removed via the water discharge valve 14. PatXML 5/9 2361
- a separating element 25 Between the Coalescerelement 20 and the particulate filter 19 is a separating element 25, this is fixed with a profile seal 26 on the outer wall of the riser 17 and ensures a liquid-tight separation of the upper inflow and the lower clean fluid range.
- the particle filter 19 and the coalescing element 20 are connected by an adhesive or welded connection or by embedding.
- the upper end plate 26 of the coalescing element has like cover 11 concentrically distributed inlet openings 27 and in the outer region a seal to the wall of the housing 10. This end plate thus forms a sealing disc, which is preferably formed in one piece. At the same time this end plate also serves as a stop for the elements 20 and 19. The stop is defined by an inwardly drawn paragraph 28 of the riser 17.
- the illustrated elements 19 and 20 are fixed in their drawn position.
- the spring element 29 also serves as a tolerance compensation for any existing length tolerances of the housing or the elements therein.
- FIG. 2 shows a detailed representation of the upper inflow region for the fuel to be cleaned.
- the same with Figure 1 parts are provided with the same reference numerals.
- the filter system is screwed to a mounting structure 30, this is done via a arranged on the lid 11 thread 31 and arranged on the mounting structure threaded sleeve 32.
- the sealing of the raw liquid area via a profile seal 33.
- the end plate or sealing washer 26 consists of a thermoplastic material, which is tapered in the outer region to the housing 10 and designed in the manner of a lip 34. This, due to their structure soft elastic lip 34, a seal between the upper fluid portion 35 and the lower fluid portion 36 is achieved. Due to the shape of the lip is a compensation of tolerances of the PatXML 6/9 2361
- Figure 3 shows a sealing washer 26 in which via a, upwardly extending collar 37 a receiving groove 38 is formed, in this receiving groove, an O-ring 39 or another type of elastic seal can be inserted.
- Figure 4 shows another sealing principle of the end plate 26.
- a profile seal 40 in the manner of a U-profile, this seal is before mounting on the Pulled end plate or slipped and causes due to the relatively large seal length a particularly reliable seal. Since the lower leg of the U-profile seal does not extend into the region of the filter element, there is no restriction as regards the effective filter area, i. H. the liquid can flow up to the end disk out of the coalescing element. It becomes clear that the sealing system is located outside the effective coalescing surface.
- Figure 5 shows an axial seal 41, which is placed on the end plate 26 or glued.
- This seal is a simple, square shape designed profile seal, which also defines the axial position of the Coalescerelements and the particulate filter 19 at the same time.
- An axial stop on the riser 17 as shown in Figure 1, is not required here.
- FIG. 6 shows an end plate 26 with a two-component structure.
- the inner area of the end plate is a plastic material like PatXML 7/9 2361
