Patent ID: 8801928

Claim:
A 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; wherein the water separator ( 8 ) comprises a substantially cylindrical housing ( 9 ) whose longitudinal axis (L 1 ) is at least approximately vertical; and wherein arranged in the housing ( 9 ) an insertion element ( 10 ) is provided that comprises a vertical tube section ( 15 ); wherein an interior of the tube section ( 15 ) defines a fuel outlet passage; wherein the tube section ( 15 ) has an axial upper end which leads fuel to a fuel outlet: wherein fuel flows axially within the interior of the tube section ( 15 ) in a direction from an axially opposing lower end of the tube section ( 15 ) to the axial upper end; wherein a plate-shaped guiding element ( 18 ) is arranged on and secured onto the axially opposing lower end of the tube section ( 15 ), the plate-shaped guiding element ( 18 ) closing off the interior of the tube section at the axially opposing lower end of the tube section ( 15 ), the plate-shaped guiding element ( 18 ) extending radially outwardly away from the radial outer surface of the tube section ( 15 ) and beyond the hydrophobic material to form a radially outwardly extending guide surface on which separated water is guided radially outwardly to an annular gap ( 26 ) surrounding the plate-shaped guiding element ( 18 ).
