Abstract: In a fuel filter device, in particular for diesel fuel, including a housing, which has a receiving chamber for a medium to be separated from the fuel, a valve device is provided which can be moved between a closed position closing the receiving chamber and an open position opening up the receiving chamber for the removal of the medium from the receiving chamber, the valve device comprises a valve member, which is so arranged that it is biased by the medium in the receiving chamber into the closed position, the medium pressure being exerted on a surface at the valve member for keeping the valve member in its closed position.

Abstract: In an exhaust manifold for an internal combustion engine including a central part with tow exhaust gas flow ducts extending from the central part in opposite directions for collecting exhaust gas from first and respectively second cylinder groups of the engine, the center part includes a first control valve for controlling the exhaust gas flow from the first and the second cylinder groups to first and second turbine inlet flow passages, a second control valve for controlling the exhaust gas pressure and a third control valve for controlling the exhaust gas recirculation rate.
