Exploded drawing of double flux solenoid valve From above diagrams, it is known that this kind of solenoid valve consists mainly of valve body, membrane, cone-shaped spring, valve cover, pilot valve, control valve of small flux, reposition valve, winding of pilot valve and small flux valve winding. The working principle of double flux solenoid valve can be leaned from Diagram 2-35. Pilot valve, small flux valve and main valve controlled by membrane are closed after power cut, no oil pass solenoid valve. When both two windings are open, pilot valve and small flux valve switch on, pressured oil pushing down membrane. Part of oil in A chamber flow toward outlet of solenoid valve via pilot valve and small flux valve, main valve is switched on after overcoming spring, at this state, solenoid valve is in large flux. When winding of pilot valve is cut power, pilot valve is closed, membrane go upward so as to close main valve due to oil pressure increase in A chamber. Solenoid valve is in small flux state. If fuel dispenser the power of winding of small flux valve is cut off, small flux valve is closed, n fuel dispenser o flux in solenoid valve. It is learned from above introduction that the large and small flux of solenoid valve are controlled by pilot valve and small flux valve. This is why it called double flux solenoid valve. As filing motor, pilot valve, small flux valve and main valve are switched on, fuel dispenser work in large flux state. When filling volume nearly reach presetting value, winding power of pilot valve is cut off, main valve is closed. However, small flu fuel dispenser x valve is still working. When filling volume reach preset-value, the winding power of small flux valve is cut off, solenoid valve is closed. Filling operation is end. Troubleshooting In filing operation some troubles maybe correlate to solenoid valve, some maybe to other hydraulic components. Small flux or no delivery in fuel dispenser, for example, it is possible caused by solenoid valve or other components. Therefore, it is need to give concrete analysis and diagno

ng in the United States, allowing Americans to buy lots more Asian exports—which, the authors argue, suits both Asia and America. Furthermore, they say, opening its doors to foreign direct investment (FDI) has helped China to build a world-class capital stock. Emerging economies with poorly developed financial markets are not good at allocating capital, so they buy Treasury bonds and let American firms do the domestic investment for them. Admittedly the return on Treasury bonds is lower than the return on FDI, but this, the authors reckon, is a small price to pay for more efficient domestic investment and hence faster long-term growth. The bottom line of this theory is that the main blame for America s deficit lies with Asia s emerging economies, rather than with America itself. And because the arrangement is in those Asian countries economic interest, the theory suggests, they will go on financing America s deficit for a good many years. Lost in the woods However, Morris Goldste fuel dispenser in and Nicholas Lardy, at the Institute for International Economics in Washington, fuel dispenser DC, argue that Bretton Woods 2 does not explain China s behaviour in the past, and it certainly would not be in China s interest to go on behaving that way in future. The first flaw in the theory is that America takes only one-fifth of China s exports, with Europe a close runner-up. So if China were trying to keep the yuan undervalued, it would surely do better to hold down its real trade-weighted exchange rate, which rose by 35% during the dollar s climb from fuel dispenser 1994 to 2001. China s main motive for tying the yuan closely to the dollar has been financial stability, not crude mercantilism. But now a rigid exchange rate looks as though it might become a source of instability. The large build-up of reserves that has resulted from currency intervention is creating excess liquidity, with its attendant risks of inflation, asset-price bubbles and a serious misallocation of capital. The dollar “peg�has forced China to ad
