In a conduit section (22) parallelly connected to the by-pass conduit, a check valve (23) is provided. Upstream from a suction tube (18) before the by-pass conduit and the parallel conduit section, a regenerating valve (24) is provided. The pump (21) is provided in a by-pass conduit (19), which branches from the suction tube and is coupled to a suction nozzle to the tank venting conduit. Between the suction nozzle and the adsorption filter (14) a regenerating valve is fitted.
