Abstract
A ring filter element comprising a plug for, in particular, a lubricating oil filter of an internal combustion engine. Said ring filter element is provided for insertion into a filter housing comprising a filter housing pot and a filter cover that can be axially detached. When inserted in the closed filter housing, the plug seals an opening which is provided in the filter housing pot and which extends in the same axial direction as the plug. The aim of the invention is to provide a ring filter element of the aforementioned type that can be packed in a space-saving manner. To this end, the ring filter element comprises the following characteristics: the plug is mounted on the ring filter element in such a manner that it can be displaced along to same axis or parallel to the axis, and; said mounting permits the plug to move with the aid of an actuating means which acts, by contact, upon the lug from outside the ring filter element.
