Embodiment Construction

[0029] exist figure 1 A fuel vapor storage and recovery device 1 according to a first embodiment of the present invention is shown in . The fuel vapor storage and recovery device 1 comprises a generally cylindrical housing 2 enclosing a main vapor storage compartment 3 and further vapor storage compartments 4, 5 and 6. The housing includes a vapor inlet 7 , an atmospheric vent 8 and a purge port 9 .

[0030] All the vapor storage compartments 3, 4, 5 and 6 are connected in series, and the main vapor storage compartment 3 surrounds the second vapor storage compartment 4 and the third vapor storage compartment 5, i.e. the main vapor storage compartment 3, the second vapor storage compartment The vapor storage compartment 5 and the third vapor storage compartment 6 are arranged in concentric relationship to each other. The main vapor storage compartment 3 as well as the second vapor storage compartment 4 and the fourth vapor storage compartment 6 are filled / packed with granula...

Abstract

The invention refers to a fuel vapor storage and recovery apparatus (1) comprising at least one main vapor storage compartment (3) filled with an adsorbent material, at least one vapor inlet port (7), at least one atmospheric vent port (8) and at least one purge port (9), said vapor inlet port (7) being connectable to a fuel tank venting line and said purge port (9) being connectable to an engine air intake line, wherein said main vapor storage compartment (3) comprises a purge buffer zone (14) as well as first and second fuel vapor distribution chambers (10, 24) not filled with an adsorbent material. Said first fuel vapor distribution chamber is arranged upstream said purge buffer zone (14) and communicates with said fuel vapor inlet port (7). Said second fuel vapor distribution chamber (24) is arranged downstream said purge buffer zone and communicates with said purge port (9).

Description

technical field [0001] The present invention relates to a fuel vapor storage and recovery device comprising: at least one primary vapor storage compartment filled with adsorbent material, at least one vapor inlet, at least one atmospheric outlet, and at least one A purge port, the vapor inlet connectable to a fuel tank drain line and the purge port connectable to an engine air intake line, wherein the main vapor storage compartment includes a purge buffer zone. Background technique [0002] Fuel vapor storage and recovery devices of the type described above are generally known in the art and are sometimes referred to as so-called canisters. Gasoline fuel used in many internal combustion engines is highly volatile. Emissions of evaporative exhaust fuel vapors from vehicles with internal combustion engines are primarily due to venting of the vehicle's fuel tank. During shutdown, temperature or pressure changes cause hydrocarbon laden air to escape from the fuel tank. Some o...
