Abstract
The invention relates to a fuel filter through which the fuel is to flow, in which water-separating, permeable layers are arranged spaced apart from one another in the direction of flow upstream of the filter layer, each time during operation of the filter the free space that lies between the two layers is connected to a first water collecting space, lying on the bottom of the filter, the first water collecting space lies below both the filter layer and the two permeable layers, is intended to permit a high degree of water separation. For this purpose, such a fuel filter is distinguished by the fact that the filter tube space lying upstream of the layer that is flowed through first of the two layers is connected to a second water collecting space within the filter, the assignment of which to the filter layer on the one hand and to the two permeable layers on the other hand coincides with that of the first water collecting space with respect to these components.
