Problems solved by technology

An additional filter medium constructed in this way disadvantageously increases the flow resistance of the filter system or filter element
In addition, the service life of the filter system or filter elements is reduced due to additional filter elements
Finally, due to errors in the processing of the additional filter medium (especially when pressing and folding) the barrier function of the additional filter medium can be lost

Embodiment Construction

[0031] figure 1 A filter system 10 according to the invention is shown. Filtration system 10 includes a filter housing 12 . A first replaceable filter element 14 is arranged in the filter housing 12 .

[0032] The filter housing 12 includes an inlet 16 and an outlet 18 for the fluid to be filtered, in particular for fuel. The filter housing 12 is therefore flowable as indicated by the arrows 20 , 22 , the filtering process mainly taking place in the first filter element 14 .

[0033] The first filter element 14 has a filter medium 24 . The filter medium 24 is arranged between a first end plate 26 and a second end plate 28 of the filter element 14 and is designed as a glass fiber filter medium 24 . Individual glass fibers can break out of the glass fiber filter media 24 and foul the fluid. Components 32 of fiberglass filter media 24 are shown in figure 1 shown particularly large. The actual component 32 of the glass fiber filter medium 24 has a length of up to several mi...

Abstract

The invention relates to a filter system (10) having a filter element (14) and a glass fiber filter medium (24). The filter system (10) further comprises a sintered body (34), which prevents unintentionally dissolved constituents (32) of the glass fiber filter medium (24) from leaving the filter system (10). To this end, the sintered body (34) preferably has passages, that is, pores, that are offset transversely to the flow direction of the sintered body (34) such that the constituents (32) of the glass fiber filter medium (24) become wedged together in the pores of the sintered body (34). The recesses of the passages can have an average clearance of more than 10 [mu]m, in particular of more than 20 [mu]m, preferably of more than 30 [mu]m, and particularly preferable of more than 40 [mu]m, in order to keep the flow resistance of the sintered body (34) low. In the filter system (10), a sintered body (34) can be arranged inside the filter element (14) and / or outside the filter element (14). The invention further relates to a filter element having a glass fiber filter medium and a sintered body that is fluidically downstream of the glass fiber filter medium.

Description

technical field [0001] The invention relates to a filter system and a filter element for filtering fluids. The filter system and the filter element are preferably applicable in motor vehicles, in particular for filtering fuel. Background technique [0002] A filter element for liquids and gases is known from document US 6,096,212 A. The filter element has a filter medium which is arranged between two end disks of the filter element and which is folded star-shaped in a known manner. The filter medium is configured as a sintered body, which is formed from a plurality of metal fibers. [0003] Document EP 1 000 649 A1 discloses a water circuit with filter stages. The filter stage has a cartridge with a barrier layer of sintered plastic. [0004] Furthermore, DE 10 2011 003 645 A1 discloses a filter device for filtering fluids of an internal combustion engine of a motor vehicle. The filter device has a filter housing and a filter element arranged in the filter housing. In ...
