A fuel filter has a housing having an intake and an outlet. A filter element is arranged in the housing such that a filtered area is separated seal-tightly from an unfiltered area. A flow passage is provided between the unfiltered area and the filtered area. A porous filter member closes off the flow passage, wherein the porous filter member is arranged seal-tightly on a wall arranged about the flow passage. The filter element has a filter medium and a geodetically upper and a geodetically lower terminal disks arranged at end faces of the filter medium. The filter medium is connected seal-tightly to the terminal disks. The flow passage is arranged in the geodetically upper terminal disk that forms the wall.

Fuel filter

A fuel supply device (), particularly for an internal combustion engine (), is equipped with a particulate filter and a water trap. In order to improve the separation effect, while simultaneously reducing the separation material that is required, it is proposed to configure the water trap () as a separate component connected downstream of the fuel filer () and to provide it with a first separation stage made of coalescent material and a second separation stage made of hydrophobic material, and to dispose the separation stages such that between them the fuel is diverted.

Fuel supply device, particularly for an internal combustion engine

A filter element in a fuel filter has an annularly arranged filter medium that is sealed at the end faces by end plates wherein a venting unit for venting gases out of the filter element area is provided. The venting unit comprises a securing ring that clamps, in the mounting position, a filter body, wherein in the securing ring a through opening as well as additionally an expansion opening are provided.

Filter element in a fuel filter

A fuel filter system, particularly a diesel filter, including a housing, a particle filter arranged in the housing, and a coalescer element mounted on the particle filter. Fuel passes successively through the serially connected coalescer and particle filter. The coalescer element improves the separation of any water contained in the fuel to be filtered, while exhibiting no or no significant fuel-filtering properties.
