Patent ID: 7824550

Claim:
A fuel filter with a filter layer through which the fuel is to flow, wherein water-separating, permeable layers ( 9 , 10 ) are disposed spaced apart from one another in the flow direction upstream of the filter layer, a free space ( 11 ) lying between the two layers ( 9 , 10 ) is connected to a first water collecting space ( 16 ) lying beneath the filter, the first water collecting space ( 16 ) lies below both of the filter layer and the two permeable layers ( 9 , 10 ), wherein a filter untreated space ( 5 ) lying upstream of the layer ( 10 ) that is flowed through first of the two layers ( 9 , 10 ) is connected to a second water collecting space ( 15 ) inside the filter, both water collecting spaces ( 15 , 16 ) lie beneath both the filter layer and the two permeable layers ( 9 , 10 ), the permeable layers ( 9 , 10 ) are both water-separating and are upstream of the water collecting spaces.
