Abstract

An adsorption filter for a fuel vapor retention system of a fuel tank of an internal combustion engine. The system has a valve that can be connected to an intake tube of the engine via a connecting line that is attached to the valve and to the fuel tank via a tank line. The tank line is attached to a housing of the adsorption filter and the valve is secured on the housing of the adsorption filter so that the valve can be slid into an opening provided in the housing. The adsorption filter according to the invention is suited for a fuel vapor retention system, for mixture compressing internal combustion engines with externally supplied ignition.
