Abstract

The invention relates to an oil filter arrangement having a housing comprising a receiving space for a filter element, wherein a discharge opening is provided at the bottom of the receiving space and a discharge valve is provided in the discharge opening wherein the discharge valve comprises a valve body, which is movable between a closing position and an opening position in a displaceable manner and is moved to the locking position by a first spring element when the filter element is inserted, wherein the first spring element is disposed on the valve body on the side of the valve body facing away from the discharge opening and is configured as a compound spring having a flat, bent metal band. The metal band acts against the filter element or against an end disk of the filter element when the filter element is inserted.
