A dust filter is configured to filter air drawn into a vehicle canister. The dust filter includes a first portion including a first engaging portion and a second portion including a second engaging portion. The second portion is attached to the first portion by engagement of the second engaging portion with the first engaging portion. The first portion includes a filtration member and a case. The case includes an inner chamber within which the filtration member is disposed. The case includes a drainage port configured to drain liquid that has infiltrated the inner chamber. The second portion is attached to the first portion to form a cover that covers the drainage port together with the first portion. The cover has an outlet that opens to the outside at a position lower than the drainage port.

Dust filter

A dust filter is configured to filter air drawn into a vehicle canister. The dust filter includes a filtration member and a case. The case has an inner chamber for accommodating the filtration member. The case has a drainage port for draining liquid that has infiltrated the inner chamber. The drainage port is at least one opening formed at the bottom of the inner chamber. The case includes a cover that covers the drainage port. The cover has an outlet that opens to the outside. The outlet is lower than the drainage port. At least one baffle plate is disposed inside the cover. The baffle plate has a slope on the side of the baffle plate facing the drainage port, thereby forming a ramp.

A fuel vapor processing apparatus may include a case defining therein a first adsorption chamber, a second adsorption chamber and a non-adsorption chamber communicating between the first adsorption chamber and the second adsorption chamber. The cross sectional flow area of the first adsorption chamber may be smaller than the cross sectional flow area of the second adsorption chamber.

Fuel vapor processing apparatus

An evaporated fuel treating device lowers the blow-by volume of evaporated fuel emitted to the atmosphere via a casing having an atmospheric port. The casing has in series a first adsorbent chamber housing an adsorbent material, a space chamber not housing an adsorbent material and a second adsorbent chamber housing an adsorbent material. Each of the chambers is positioned beside an adjacent chamber thereof. The first chamber is disposed closest to the atmospheric port among the adsorbent chambers. An end part of the space chamber on a side of the first chamber has a first partition wall having an opening part with a plurality of first openings provided on a top side of the first partition wall. A current plate has one end positioned between the adjacent first openings and a surface and a rear face of the current plate are disposed along the top and bottom direction.

Evaporated fuel treating device

An apparatus including a canister and an accessory component associated with the canister. The canister may be filled with an adsorption material for adsorbing fuel vapor generated within a fuel tank. A communicating pipe extends downwardly from a housing of the accessory component for communication with the canister. An engaging protrusion is provided on an outer peripheral surface of the housing. An outer peripheral portion of an upper portion of the canister includes a wall portion for engagement with the engaging protrusion.

Apparatus having a canister and a component associated with the canister

A canister includes a canister case having an adsorbent chamber, an adsorbent housed in the adsorbent chamber of the canister case, a filter disposed between the adsorbent chamber and a port mounted on an end wall of the adsorbent chamber, and a tentative filter engaging projection provided in the adsorbent chamber. The filter is loosely fitted within the adsorbent chamber and then welded on the end wall of the adsorbent chamber. The tentative filter engaging projection tentatively holds the filter loosely fitted within the adsorbent chamber in a welding step of the filter.

Canisters

One aspect according to the present disclosure includes a first coupling device and a second coupling device. The first coupling device can mechanically couple the canister and the accessory component to each other. The second coupling device can couple the canister and the accessory component to allow flow communication with each other. The second coupling device is operable in conjunction with the operation of the first coupling device.
