CANISTER FOR VEHICLES AND FUEL SUPPLY SYSTEM PROVIDED WITH THE SAME
First Claim
1. A canister for vehicles provided with an activated carbon therein so as to absorb an evaporation gas evaporated from a fuel tank, and releasing the absorbed evaporation gas so as to supply to an engine, the canister comprising:
- a housing to receive the activated carbon therein;
an evaporation gas supply passage formed to the housing to be fluid-connected to the fuel tank and receive the evaporation gas from the fuel tank;
an air passage formed to the housing and selectively receiving an air from the exterior of the housing; and
a purge passage formed to the housing to be fluid-connected to a purge line so as to supply the evaporation gas to the engine according to a flow of the received air,wherein the purge passage is provided with a first purge passage formed to the housing and directly fluid-connecting the housing to the purge line and a second purge passage formed to the housing and having an end portion positioned inside the first purge passage or the purge line so as to be fluid-connected to the purge line.

5. A fuel supply system comprising:
-
a fuel tank connected to a refueling line so as to receive a fuel, exhausting an evaporation gas therein through an evaporation gas line, and supplying the fuel through a fuel supply line; an engine connected to the fuel supply line so as to receive the fuel from the fuel tank, and connected to an intake passage so as to receive an air; a purge line connected to the intake passage; and a canister provided with a housing to receive an activated carbon for absorbing the evaporation gas therein through the evaporation gas line, and comprises; an evaporation gas supply passage formed to the housing and fluid-connected to the evaporation gas line so as to receive the evaporation gas; an air passage connected to an air supply line so as to receive an air from the exterior of the housing; and a purge passage formed to the housing to be fluid-connected to the purge line, releasing the evaporation gas absorbed at the activated carbon according to a flow of the air received through the air passage, and supplying the evaporation gas to the intake passage, wherein the purge passage is provided with a first purge passage formed to the housing to directly fluid-connect the housing to the purge line and a second purge passage formed to the housing and having an end portion positioned in the first purge passage or the purge line so as to be fluid-connected to the purge line. - View Dependent Claims (6, 7, 8, 9, 10)
