Abstract
A canister is taught that includes a container 10 containing granular adsorbent materials 30 that can adsorb fuel vapor generated from a fuel tank, and a plate-shaped dividing member 40, 45, 48, 65 and 72 that is disposed in the container 10 in order to carry the adsorbent materials 30. The dividing member 40, 45, 48, 65 and 72 is formed with a large number of elongated ventilating holes 60 and 68 for flowing the fuel vapor. Each of the ventilating holes 60 and 68 has an opening length 60L larger than a length 30L of the adsorbent materials 30 and an opening width 60w that can restrict passage of the adsorbent materials 30.
Claims26
A canister, comprising:
- a container containing granules of adsorbent materials that can adsorb fuel vapor generated from a fuel tank;
- and
- a plate-shaped dividing member that is disposed in the container in order to carry the granules of adsorbent materials,
- wherein the dividing member is formed with a large number of elongated ventilating holes for flowing the fuel vapor, and
- wherein each of the ventilating holes has an opening length larger than a length of individual granules of the adsorbent material and an opening width that can restrict passage of the granules of adsorbent materials.
A canister, comprising:
- a container containing granules of adsorbent materials that can adsorb fuel vapor generated from a fuel tank;
- and
- a plate-shaped dividing member that is disposed in the container in order to carry the granules of adsorbent materials,
- wherein the dividing member is formed with a large number of elongated ventilating holes for flowing the fuel vapor,
- wherein each of the ventilating holes has an opening width that can restrict passage of the granules of adsorbent materials, and
- wherein the dividing member has recessed portions that are formed in its surface that faces the adsorbent materials, so as to communicate between openings of the ventilating holes.
