Abstract

PURPOSE: To balance each pressure in and out of a fuel tank and eliminate any prefiring of evaporated gas at time of oil supplying by forming a bypass passage with a valve in an evaporation line of the fuel tank, and opening the valve as long as the specified time immediately after engine stoppage.
CONSTITUTION: At time of engine driving, a solenoid valve 13 in a bypass pipe 11 is closed. Evaporated gas existing in an upper space 3 in a fuel tank 1 is passed through an evaporation pipe 4 and a check valve 5 and then guided to an inlet pipe 10a of a canister 10. On the other hand, at time of engine stoppage, a timer circuit 12 is operated and the solenoid valve 13 is opened as long as the specified time from immediately after the stoppage. With this constitution, positive pressure existing in the upper space 3 in the fuel tank 1 is set free into the atmosphere via a drain pipe 10c of the canister 10. Accordingly, even if a filler cap is removed, each pressure inside and the outside is balanced by the atmosphere, so that any blowout of the evaporated gas from a neck part 7 is thus eliminable.
