Patent ID: 8329033

Claim:
Fuel supply device ( 1 ) for an internal combustion engine ( 6 ), comprising a particulate filter and a water separator, wherein the water separator ( 5 , 8 , 30 ) is embodied as a separate component downstream of the particulate filter ( 4 ) and comprises a first separating stage (A 1 ) with hydrophilic coalescent material as well as a second separating stage (A 2 ) with hydrophobic material and wherein the separating stages (A 1 , A 2 ) are arranged such that between them a diversion of the fuel is realized; a housing ( 31 ) having an at least approximately horizontal longitudinal axis (L 2 ); an elongated inner part ( 35 ) arranged within the housing ( 31 ) and extending in longitudinal direction of the housing ( 31 ); wherein the elongated inner part is arranged eccentrically relative to the longitudinal axis (L 2 ); wherein the elongated inner part includes a fuel inlet chamber ( 38 ) formed within said elongated inner part ( 35 ) and opening through an axial end of said elongated inner part; a fuel outlet chamber ( 39 ) formed within said elongated inner part ( 35 ) and arranged in direction of said approximately horizontal longitudinal axis (L 2 ) axially behind said fuel inlet chamber ( 38 ), said fuel outlet chamber ( 39 ) extending at least partially over said fuel inlet chamber ( 38 ) and opening through an opposing axial end of said elongated inner part; a slantedly positioned partition ( 40 ) arranged between said fuel inlet chamber ( 38 ) and said fuel outlet chamber ( 39 ), said partition separating said fuel inlet chamber from said fuel outlet chamber; a separating chamber ( 43 ) arranged within said housing ( 31 ) below said axially spaced fuel inlet and outlet chambers; a bottom wall of said a fuel inlet chamber ( 38 ) delimiting said fuel inlet chamber ( 38 ) at its bottom side and separating said fuel inlet chamber ( 38 ) from said separating chamber ( 43 ), said bottom wall having an opening ( 41 ) completely covered by at least one layer ( 42 ) of said hydrophilic material forming said first separating stage (A 1 ).
