Fuel filter

摘要

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).

主权项

1. A fuel filter for an internal combustion engine of a motor vehicle, the fuel filter comprising:
a fuel filter housing having a collection chamber; a filter element arranged in the fuel filter housing, the filter element configured to separate water from a water-fuel mixture and discharging the water into the collection chamber of the fuel filter via a first conduit; wherein the fuel filter has a second conduit recirculating at least a part of the water-fuel mixture into a fuel tank of the motor vehicle; and wherein the second conduit branches off from the first conduit.
