Abstract
A diesel fuel filter, which is arranged in a conduit between a fuel tank and a fuel injection pump, comprises a housing accommodating a filter element and a cover non-releasably connected to the housing. A temperature-responsive switching device for switching fuel overflow quantities from the pump to the tank as well as a ventilation device are positioned in a chamber formed by a protruding formation of the cover and a flat plate connected to the housing. A plate shaped pressure control valve, which opens into a contaminated side of the filter element, connects that side to the chamber.
