used to keep a certain position to refuel. Working principal Pressured oil flow into the chambers in where main and vice valve located after switching main valve and flow out of spout because vice valve is opened. Liquid flowage reduces the static pressure and the pressure in upper chamber of switch. The pressure on the chambers of upper and low switch membrane are equivalent due to the front of spout communicating atmosphere. When inlet vent is flooded by oil, the lower chamber of switch membrane still keeps atmospheric pressure. Thus, pressure difference is generated between the upper and lower chambers of switch membrane, the membrane and auto-shut level moving upward, auto controlled level moves downward under the function of switch handle. Finally, steel ball is driven into the hole of auto controlled level; switch handle continues to move downward; main valve is closed. In order to form the auto-shut function, two oil passages with different sections should be set (See Diagram 2-32). Here the Bernoulli equation as followed in order to explain the principle of auto-shut: �? = 12 ρv12+ρgh1=�?+12ρv22+ρgh2 (2--6) Among the above formula: ρ── oil density �?── pressure in main valve passage v1 ── velocity of flow in main valve passage h1── height of main valve �?── pressure in vice valve v2── velocity of flow in vice valve passage h2── height of vice valve Diagram 2-32: Auto-shut nozzle Due to small nozzle body, it could be regarded as a horizontal pipe, that is h1= h2 From Formula 2-6: �?－ｐ2�?2ρ(v22－v12) (2-7) According the following Formula: v1v2=A2 A1 In the Formula: A1 ── section of main valve passage A2 ── section of vice valve passage The Formula can be converted into: �?－ｐ2�?2ρv22 [1�?A2A1)] It is fuel dispenser known from Formula 2-8 that if A2 / A1 is certain value, P2 becomes a negative fuel dispenser value when velocity of flow increasing a certain extent, that is, P2 fuel dispenser smaller than at

limitations, India s tertiary education is a relative success. A bigger difficulty is delivering basic education to the villages, to equip potential workers with the elementary literacy and other skills needed to leave the land. Even in the well-educated southern state of Tamil Nadu, Nokia, which seeks people with at least 12 years of schooling, has to bring in some of its workers 100km (about 60 miles) by bus. Some analysts predict that India is about to see a boom in labour-intensive manufacturing similar to that in the Chinese countryside in the 1980s. In a report last October entitled “From White Collar to Blue�? Sanjeev Sanyal of Deutsche Bank argued that “India s skills-driven growth trajectory is about to change. The small but highly educated middle class is rapidly re-pricing itself...Does this mean that the India story is about to end? No. In our view, the country is about to benefit from a new dynamic—a primary-education revolution that will soon make available a mass of cheap low-skill labour.�? Both halves of this argument are suspect. The “re-pricing�?of the urban middle class is undeniable, but India s demographic and other advantages are such that this need not take a toll on growth for a while yet. Second, the “revolution�?in primary education is patchy at best. There are still parts of the country where teachers, let alone pupils, rarely go to school. A charity working in a part of the southern state of Andhra Pradesh where, according to the census, there is 100% literacy, in fact found 45% illiteracy in the 15-45 age group. The official national literacy rate of 61% includes many who are able to write their names but are functionally illiterate.
