ABSTRACT:
An apparatus for the temporary storage and controlled feeding of volatile fuel components from the free space of a fuel tank to the intake manifold of an internal combustion engine is set forth. The apparatus includes a venting line which connects the free space of the fuel tank to the atmosphere. Along this line is interposed a storage chamber containing an absorption element having at least one line which connects the storage chamber to the intake manifold and which can be sealed by an electromagnetically actuated valve. Valve includes a valve seat and a nozzle. The nozzle tapers away from the valve seat at one end to a cross section of reduced area, and then conically widens to a maximum value at the opposite end of the nozzle.
