Filter arrangement

摘要

A filter arrangement having an upright filter with a filter housing and a filter insert for cleaning lubricating oil of an internal combustion engine, in which the filter is fastened at a filter socket located in the lower part in the installed position of the filter; a first channel for feeding dirty oil, a second channel for discharging clean oil and a third channel for discharging oil from the interior of the filter are provided in the filter socket as well as a passage from the interior of the filter housing to the third channel which is necessarily opened during a change of the filter insert. In order to achieve a clear separation of the clean oil from the oil flowing off out of the filter during a change of the filter, the passage is arranged in a collar of the filter socket closely surrounding the lower part of the filter housing and is covered off by the filter housing in the installed position thereof.
