ABSTRACT:
An air intake filter containing a filter insert within a canister. The canister includes a raw air inlet and an opening for the introduction of the filter insert, the filter insert having a sealing surface parallel to the plane of the opening to seal the clean-air side. This sealing surface is applied to another sealing surface on an adapter with a sealing ring interposed therebetween, and the canister is fastened to the adapter. To prevent any shearing movement on the sealing ring when the canister is attached to the adapter, a guide is provided on the adapter and is engaged by a sliding shoe disposed on the canister. Furthermore, a spacer is situated on the canister and assures that the canister cannot be laid against the adapter unless the two sealing surfaces are correctly positioned with respect to one another.
