Filter mit einem durch mindestens eine Verstärkung verstärkten Gehäuse

摘要

The invention relates to filter, especially for the intake air of an internal combustion engine which filter comprises reinforcements for the housing parts (10, 11). The reinforcement consists especially of a stay consisting of a hollow tube (21) and a threaded tube (22). Said tubes are stably linked with one another by means of a screw (23), thereby allowing a good bracing of the filter housing. The bracing of the filter housing effectively reduces the natural vibration of the housing while the overall weight of the filter remains substantially the same. Provision of such a stay is made possible by a recess (24) in the filter element (12). Said recess carries an additional seal (25) which seals the recess towards the tube. In this manner, the raw side (14) and the clean side (15) of the filter are reliably sealed from one another. In addition, the mounting of the additional seal between the hollow tube (21) and the threaded tube (22) can additionally stabilize the flat filter element.
