Zusammenfassung:	PCT No. PCT/DE97/01137 Sec. 371 Date Oct. 30, 1998 Sec. 102(e) Date Oct. 30, 1998 PCT Filed Jun. 6, 1997 PCT Pub. No. WO97/47874 PCT Pub. Date Dec. 18, 1997A process and device are provided to supply the air mass flux required to regenerate the adsorption material of an adsorption filter in the fuel tank venting system of an internal combustion engine while the engine is running and independently of a depression in the air intake pipe of the engine. For this purpose, atmospheric air is fed at least partially and temporarily by an air pump through the adsorption filter to the air intake pipe of the internal combustion engine while the engine is running. The air pump integrated in the device makes it possible to obtain a module which is easy to produce and to handle and which contains all units of the venting system.
