Abstract
A filter device has a cup-shaped filter housing (), a filter element () in the housing and at least one end cap (). A retaining device detachably fixes the filter element () along its longitudinal axis and has screwing elements () interacting with each other and configured on the interior of the filter housing () and on the filter element (). A sealing device () forms the seal between the filter element () and a housing terminating part () limiting the filter housing () at an end. The housing terminating part () forms an element receiving device having a fluid passage () concentric to the longitudinal axis (). The fluid passage has inner screwing elements (). A connecting piece () of the end cap () is able to be screwed into the passage using outer screwing elements (). The sealing device has a sealing element () that is combined with the end cap () to form a cohesive component and that is accommodated in a seat () configured at the transition between the end cap () and the adjacent beginning of the thread turns () of the screwing elements () positioned at the connecting piece ().
