Abstract
An apparatus for temporarily storing and feeding in measured quantities the volatile fuel components found in the free space of a tank installation into the intake tube of an internal combustion engine includes a vent line which connects the free space to the atmosphere. A storage chamber with an absorption element is arranged in the vent line. A line connects the storage chamber to the intake tube and is capable of being sealed by a valve. A throttle valve is supported on a drive shaft and is configured in the intake tube. The valve includes an actuator, which is capable of being operated by the drive shaft.
