Abstract
A filter device has a filter housing () with a filter head (), a filter pot () and a removable housing cover part () and has a filter element () separating a non-filtrate side () from a filtrate side () in the housing. A bypass valve device has a valve closure element () preloaded by a closing spring () into a closed position in which it bears against a valve seat part (). If the filter element () is blocked, the closure element opens up a fluid path from the non-filtrate side () to the filtrate side (), by passing the filter element (). The valve closure element () and the closing spring () are on the cover part (). The valve seat part () is on an element cap () of the filter element (). The element cap has a receiving part () forming an enclosure for that end of the filter material () of the filter element () facing toward the cover part ().
