  • Arrangement for draining water collecting in the container of a water separator of an internal-combustion engine
    Patent number: 5053120
    Abstract: The invention relates to an arrangement for the automatic removal of water collecting in a fuel filter having a water separator. The evacuation takes place by means of a piston acted upon by a pressure medium, preferably a fuel pressurized by the pressure of the fuel pump, the piston being guided in the container of the fuel filter containing the water. It is particularly advantageous for an already existing drive to be usable for producing the pressure medium and that therefore a simple and inexpensive solution is offered for the removal of the water.
