    摘要： A canister (1) for filtering fuel vapours coming from a motor-vehicle fuel tank (3), comprises at least one chamber (180) containing adsorbing material (18) in the form of particles or granules. Freely floating between the particles or granules of adsorbing material (18) there are arranged one or more flexible sheets (F1-F6) of a material substantially impervious to air, so as to define a tortuous path for communication between an opening (4) of the canister communicating with the atmosphere and an opening (6) of the canister communicating with the intake manifold (11) of the internal combustion engine (10) of the motor-vehicle. When the internal combustion engine is in operation, an air flow is drawn into the canister through the above indicated opening (4) communicating with the atmosphere. This air flow passes through the particles or granules of adsorbed material (18) and exits from the above indicated opening (6) communicating to the intake manifold (11) of the engine. In this manner, a scavenging of the adsorbed material is obtained, with a removal of the fuel particles retained therein. The flexible sheets (F1-F6) are arranged so as to cause the above indicated air flow to follow a tortuous path through the canister, so as to achieve an efficient scavenging action.

    摘要： A vehicle tank pressurisation device has a valve seat (10) establishing an opening (11) for fuel vapours and/or air; such opening (11) has a vertical axis (12) coincident with the direction of application of an opening force, that is directed upwards and is produced, in use, by the pressure in an internal upper region (6) of the tank (1); the device also has a movable shutter (14), placed on the valve seat (10), to open/close the valve seat (10), and having a weight set by design in such a way as to define the magnitude of a closing force directed downwards and with a centre of gravity positioned eccentrically with respect to the vertical axis (12) of the opening (11).
