| 摘要 |
The invention relates to a fuel filter having a ventilation unit (25) which can be operated in a suction mode. The fuel filter has an openable housing (10) in which a filter element (17) is arranged. The filter element (17) sealingly separates an unclean region (23) from a clean region (24). In order to discharge gases which have accumulated in the upper region of the housing (10), a flow duct (33) is provided which is covered by the ventilation unit (25). The ventilation unit (25) comprises a porous filter body which is permeable to gases. The gases can therefore be conducted as very finely distributed gas bubbles from the unclean region (23) to the clean region (24) without the function of an associated internal combustion engine being adversely affected. |
