摘要:
Liquid filters having a filter housing are already known, which filters have a cylinder section and two end bases, wherein at an inside of at least one base, radially proceeding ribs of constant height are arranged. The requirements of pressure resistance of engine fuel filters have greatly increased as a result of higher system pressures and owing to the fact that, even with the engine shut off, the engine fuel filters in current engine fuel transport systems are under high pressure which can even exceed the system pressure in the shut-down case owing to the remaining heat of the engine. In the liquid filter according to the invention, the pressure strength of the filter housing is substantially increased. It is provided according to the invention that the height (H2) of the ribs (8), measured in one axial direction in relation to a cylinder axis (3), increases radially towards the interior.
