Summary:A filtering system has a filter housing and a filter element and having a raw side and a clean side arranged in the filter housing. Liquid introduced into the filter housing flows through the filter element from the raw side to the clean side. An overflow valve is disposed between the raw side and the clean side of the filter element. The overflow valve is moved into an open position should a pressure of the liquid on the raw side of the filter element surpass a limit value. The overflow valve has an adjustable valve body loaded by a valve spring and made from plastic material. The filter element and of the filter housing structurally supplement one another such that the filter element is positioned precisely in the filter housing and relative rotation of the filter element relative to the filter housing is prevented.
