    • This invention relates to a device for recovering fuel vapor in a fuel tank, in particular of a motor vehicle, the device comprising:

      . a filter (5) suitable for adsorbing gaseous fuel, the filter having two orifices (4,15) situated at opposite ends of a filter body (5a) ; and
      . a condenser (8) suitable for condensing the gaseous fuel, the condenser comprising a condensation portion (8a) designed to contain gases, and a recovery portion (8b) designed to contain liquids, the condensation portion being connected to the filter via a transfer duct (6), and the recovery portion being connected to the tank via a return duct (9);

      It includes:

      . two three-way distributor valves (3,14) each installed on a respective orifice of the filter, these two distributor valves being suitable, in a first or 〈〈 adsorption 〉〉 position for putting one of the orifices of the filter into communication with a collection duct for collecting gases and opening out into the tank (1) above the level of liquid fuel, with the other orifice of the filter being put into communication with the outside, and in a second or 〈〈 desorption 〉〉 position, for putting one of the orifices of the filter into communication with the transfer duct (6) and the other orifice of the filter into communication with a circulation duct (13) opening out into the portion of the condenser that is designed to contain gas ; and
      a pump (7) installed on the transfer duct to dirve the desorbed gaseous fuel towards the condenser when the distributor valves are in the desorption position..
