Title:
小型エンジン用燃料タンクシステムの燃料蒸気放出制御
Document Type and Number:
Japanese Patent JP2008524064
Kind Code:
A
Abstract:
A fuel vapor emission system for small engine gas tank which does not require redesign or retooling for manufacturing of the tank (10). A new filler tube (14) has the lower end positioned to cause fuel to rise rapidly in the tube (14) before the tank (10) is full, signaling the operator to stop refueling and maintain a vapor dome in the tank when the filler cap (16) is replaced. A vapor vent valve (20) is disposed in a separate access opening and includes a float operated rollover valve. The vent valve (20) opens when a predetermined positive pressure is reached in the tank (10); and, a reverse flow vacuum relief valve is disposed in the vent valve (20). The outlet of the vent valve (20) is intended to be connected to either a storage canister (70) or the engine air inlet (72).
