DEVICE FOR SELECTIVELY REGENERATING OR PERFORMING TANK LEAKAGE DIAGNOSIS OF A TANK VENTILATION SYSTEM

摘要

In a device (10) for selectively regenerating and performing tank leakage diagnosis of a tank ventilation system (12), in particular of a motor vehicle, having a sorption filter (18) for temporarily storing fuel evaporating from a fuel tank (14) and having a pump (26) arranged at the fresh-air side of the sorption filter (18), said pump being connected in fluid-conducting fashion to the sorption filter (18), the pump (26) is designed to generate a fluid flow for regenerating the sorption filter (18).
