  • Method for evacuating water that has been separated in a fuel filter and a device for carrying out said method
    Patent number: 6881328
    Abstract: A method for directly evacuating water that has been separated from the filtered fuel in a fuel filter and has settled in a water collection chamber (4) of the fuel filter to an evacuation area that lies above the water level, by opening a shut-off valve (7), which leads to the exterior of the fuel filter and is connected in a water-conductive manner to the water collection chamber (4). Said evacuation takes place under a pressure that is higher in the water collection chamber (4) in relation to the evacuation area, whereby said pressure differential is created either by the operating pressure within the fuel filter during operation, or by a negative pressure that is applied externally. The method permits the simple evacuation of water form the interior of a fuel filter by a method that is not based on gravity. The inventive method can be implemented in a particularly advantageous manner, using specially configured fuel filters.
