inlet of pump. Vapor segregated device: key component of vapor separator. It includes the following components ---High pressure chamber composed of frame and upper cover; vapor segregated chamber that used to be called general pressure chamber, due to vary along with pump pressure, returned oil floater being installed here; spheriform buoy with exhausting valve, exhausting valve seat, returned oil floater, returned oil valve and exhausting pipe. Some factories evolve the spheroid buoy with exhausting valve and exhausting seat as a ball valve, illustrating in diagram 2-15. Now some manufacturers replace ball valve with other structure that promotes the separator capacity. Diagram 2-14 Dimensional structure drawing of vapor separator 1-Valve cover 2-Vavle body 3-Steel ball 4-Upper cover Diagram 2-15 Structural drawing of single direction valve This kind of vapor segregated device has large pressure chamber in which oil flow slowly so that vapor has time upward. Therefore, this kind of vapor separator is better than that of small pressure chamber in terms of separate capacity. Anti-backward flow device: it mainly composes of spring seat, spring, check valve unit and outlet pipeline. Check valve gasket is made of oil-resistance rubber board, which is very important for realizing anti backward flow function. Working principle After starting a new fuel dispens fuel dispenser er larger air in pipeline is impelled out through check valve and exhausting valve. As there is no foam found in oil indicator fuel dispenser would be refueled. Fuel contained foam flows out of check valve through the bottom of high pressure chamber. The floater in high pressure is upward, levels of exhausting valve and its seat at parallel height, floated air and rest of oil flow into vapor separator chamber from the groove of exhausting valve. If that is ball valve, the steel ball has covered the hole on valve cover, these air and flow only flow from the g fuel dispenser roove of ball valve. The mixture of oil and air flow into vapor separator chamber in fuel dispenser

take measures to reduce its surplus. But are they heading to the right place? At the global level, the biggest counterpart to America s deficit is the combined surpluses of the oil-exporting emerging economies. They are expected to run a total current-account surplus of some $500 billion this year, dwarfing China s likely surplus of $200 billion (see chart). Counting only the Middle East oil exporters, the surplus has surged from $30 billion in 2002 to an estimated $280 billion this year. One reason why this gets much less attention than the smaller $160 billion increase in China is that only a fraction of it has gone into official reserves, which are publicly reported. Most of it is stashed in government oil-stabilisation or investment funds, such as the Abu Dhabi Investment Authority, which are much more secretive than the People s Bank of China—but which probably hold just as many dollar assets. One big difference is that China is now allowing the yuan to rise against the dollar. The exchange rate is up by an annual rate of almost 7% since September. In contrast, the six members of the Gulf Co- operation Council, or GCC (Saudi Arabia, United Arab Emirates, Kuwait, Bahrain, Oman and Qatar), which account for virtually all of the Middle East s surplus, still peg their currencies firmly to the dollar. This is partly in preparation for the GCC s plan t fuel dispenser o adopt a single currency by 2010. But the bizarre result is that over the past four years of soaring oil prices, their real trade-weighted exchange rates have fallen. The Gulf economies are running an average current-account surplus of 30% of their GDP, well in excess of China s surplus of 8%. Oil exporters cannot spend their windfall overnight and it makes sense for them to run a surplus when oil prices rise, as a buffer for when oil prices fall. Even so, one can have too much of a good thing. It might be best for the Gulf states as well as the w fuel dispenser orld economy if they abandoned their dollar pegs and shifted to some sort of curre fuel dispenser
