Patent ID: 8388834

Claim:
Fuel filter ( 1 ) with a device separating water from fuel, the device comprising a filter housing ( 2 ), a filter element ( 3 ) arranged in the filter housing ( 2 ), the filter element ( 3 ) for the filtration of particles from the fuel, at least one filter screen element ( 6 ) arranged in the filter housing ( 2 ) with the at least one filter screen element ( 6 ) arranged downstream of the filter element ( 3 ), and with a tank ( 15 ) located under the filter screen element ( 6 ) at the filter housing ( 2 ) in which droplets of the separated water are collected, and with a deviation device for deviating fuel flow from a downwards flow to an upwards flow, the deviation device positioned between the filter element ( 3 ) and the filter screen element ( 6 ), the deviation device including a housing insert ( 7 ) having an opening ( 10 ) at a lower end of the housing insert ( 7 ), the opening ( 10 ) located in at a lower position in the filter housing ( 2 ) than the filter element ( 3 ), the housing insert ( 7 ) and the filter screen element ( 6 ) forming a chamber ( 8 ) therebetween, the chamber ( 8 ) closed at its upper end, the chamber open at the opening ( 10 ), wherein the fuel flow from the filter element ( 3 ) is guided downwards in the filter housing ( 2 ) along a radial outside of the housing insert ( 7 ) in a direction towards the tank ( 15 ), the fuel flow then guided upwards into the chamber ( 8 ) through the opening ( 10 ), the flow direction deviation operative to separate emulsified water from the fuel flow.
