Abstract
The filter for the purification of a liquid of a combustion engine, particularly lubricating oil, includes a housing that has, in a bottom part, an inlet for raw liquid and an outlet for purified liquid, and an unscrewable lid. A cartridge, defined by a filtering insert and a preassembled bypass valve, is received in the housing. The insert has a flange for fixing the valve, covering an end of the filtering medium. The bypass valve can be separated from the cover such that the cartridge can be removed. The valve has a removable connection element that axially engages with a complementary securing component formed on the flange, in a locking configuration obtained by a pivoting action.
