Abstract
The device includes a filter containing a material which adsorbs the vapors coming from a tank. The filter is connected through a first duct to the upper part of the tank, through a second duct to a source of depression and through a third duct to a source of air for regenerating the adsorbent material. Apparatus is provided for heating the regenerating air. The device further includes apparatus for regulating the temperature of the air flowing in the third duct, this apparatus has a temperature response control element disposed in the filter. The device is particularly useful in automobile vehicles.
