Abstract
A fuel storage device for a motor vehicle that includes a fuel tank, a canister fluidically connected to the fuel tank, at least one separation unit configured to receive the mixture of air and hydrocarbon vapors from the canister and to separate said mixture into a hydrocarbon-rich fraction and a hydrocarbon-poor fraction, the hydrocarbon-rich fraction being sent to the fuel tank, return means for returning the hydrocarbon-poor fraction to the canister, a purge pump for purging the canister which is arranged between the canister and the separation unit, at least one solenoid valve configured to selectively send the mixture of air and hydrocarbon vapors either to the separation unit or to the fuel tank.
Claims14
A fuel storage device for a motor vehicle, comprising:
- a fuel tank,
- a canister fluidically connected to the fuel tank and configured to receive a mixture of air and hydrocarbon vapors from the fuel tank,
- at least one separation unit fluidically connected to the canister and the fuel tank, the separation unit being configured to receive the mixture of air and hydrocarbon vapors from the canister and to separate said mixture into a hydrocarbon-rich fraction and a hydrocarbon-poor fraction, the hydrocarbon-rich fraction being sent to the fuel tank,
- return means for returning the hydrocarbon-poor fraction to the canister,
- a purge pump for purging the canister which is arranged between the canister and the separation unit,
- at least one solenoid valve arranged between the purge pump and the separation unit,
- wherein said at least one solenoid valve is configured to send the mixture of air and hydrocarbon vapors to the separation unit, and the at least one solenoid valve is configured to send the mixture of air and hydrocarbon vapors directly to the fuel tank.
A device for managing a mixture of air and hydrocarbon vapors from a motor vehicle canister, the management device comprising:
- at least one air and hydrocarbon vapor separation unit configured to receive the mixture of air and hydrocarbon vapor from the canister and to separate said mixture into a hydrocarbon-rich fraction and a hydrocarbon-poor fraction, the hydrocarbon-rich fraction being sent to a fuel tank;
- a purge pump for purging the canister configured to send the mixture of air and hydrocarbon vapors from the canister to the separation unit;
- and
- at least one solenoid valve arranged between the purge pump and the separation unit,
- wherein said at least one solenoid valve is configured to send the mixture of air and hydrocarbon vapors to the separation unit, and the at least one solenoid valve is configured to send the mixture of air and hydrocarbon vapors directly to the fuel tank.
