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.
Claims17
An arrangement for draining water collecting in a container of a water separator for a fuel system of an internal-combustion engine, the water precipitating in the bottom part of the container because of the force of gravity, comprising:
- a vertically displaceable piston arranged in the container, a first space of the container being adjacent one side of the piston and serving to collect a volume of water to be drained, said first space including an openable outlet for draining water therefrom, a second space of the container being adjacent an opposite side of the piston,
- and pressure medium supplying means for selectively applying pressure medium to said second space to cause the piston to move and force water out of said first space.
