Abstract
A device for selectively regenerating and performing tank leakage diagnosis of a tank ventilation system has a sorption filter and a pump. The sorption filter is configured to temporarily store fuel evaporating from a fuel tank. The pump is arranged at a fresh-air side of the sorption filter and is connected in fluid-conducting fashion to the sorption filter. The pump is configured to generate a fluid flow to regenerate the sorption filter.
