Abstract

A device for the temporary storing and metered supplying of volatile fuel components present in the free space 22 of a fuel tank system 15 into the intake pipe 1 of a combustion engine 2. The device includes a deaeration pipe 25 which connects the free space 22 with the atmosphere 23 and in which a storage chamber 18 including an absorptive element is disposed. A pipe 20 connects the storage chamber 18 with the intake pipe and can be closed by means of an electromagnetic stop valve 13. An auxiliary valve 21 including a control chamber 14 which can be closed by means of a vacuum controller is disposed between the stop valve 13 and the intake pipe 1. A bypass 4 having an adjustable cross section is provided parallel to the auxiliary valve 21.
