摘要

The ventilating device includes the fuel tank, an adsorption filter connected to it to receive fuel vapor, with an air inlet valve, and a regenerating line to the engine, in which an air pump is fitted. A regenerating valve (9), controlled by the engine (7), is fitted in the regenerating line (5) before the air pump (8) to control the regenerating through flow.
