  • Patent number: 9573083
    Abstract: The invention relates to a fuel filter (10) having a filter element (12) for separating water from the fuel. The water can be fed into a collection chamber (24) of the fuel filter (10) via a first conduit (26), which extends from the filter element (12) to the collection chamber (24). Provided in the first conduit (26) is a branching off of a second conduit (32), which enables fluid discharge from the first conduit (26). Preferably, a throttle (34) and in particular a press-fit throttle is provided in the second conduit (32), in order to regulate the amount of outflow. The second conduit (32) preferably branches off from the first conduit (26) at substantially a 90 degree angle to the first conduit (26), so that fluid flowing in the first conduit (26) primarily flows past the second conduit (32) and reaches the collection chamber (24).
