ABSTRACT:
An evaporated fuel processing device (10), in particular for an internal combustion engine of an automotive vehicle, comprises a tank port (12) and an atmospheric port (22); a first adsorbent chamber (14) between the tank port (12) and the atmospheric port (22); and a second adsorbent chamber (18) between the first adsorbent chamber (14) and the atmospheric port (22), the first and second adsorbent chambers (14, 18) being filled with an adsorbent material (16). According to an important aspect of the invention, at least two elongate flow passages (26, 26′) are arranged in parallel between the first adsorbent chamber (14) and the second adsorbent chamber (18).
