Patent ID: 7449109

Claim:
A device for separating water and for filtering impurities out of liquid hydrocarbons or fuels, comprising a housing ( 1 ), at least one coalescer element ( 5 ) for separating water and one filter element ( 6 ) for separating impurities arranged in the housing ( 1 ), said housing ( 1 ) including a first hollow body ( 2 ) for accommodating the coalescer element ( 5 ) and a second hollow body ( 3 ) accommodating the filter element ( 6 ), said hollow bodies ( 2 , 3 ) being oriented vertically in essentially parallel relationship to one another and joined via a flow-routing component ( 4 ), the coalescer element ( 5 ) being located in the first hollow body ( 2 ) and the filter element ( 6 ) being located in the second hollow body ( 3 ) above the flow-routing component ( 4 ), the flow-routing component ( 4 ) having a lower part ( 4 a ) forming a water collection area, and being relatively large so as to form a calming zone in which the flow velocity is greatly reduced for calming the flow on its way to the filter element ( 6 ) in the flow-routing component ( 4 ), the second hollow body ( 3 ) having at its end which is inclined toward the flow-routing component ( 4 ) a downwardly narrowing cross sectional area ( 9 ) with a flow passage (A 2 ).
