mospheric pressure. If v1is certain, the less A2 / A1 the much v2, which are got from Formulae 2-7 and 2-8. Automatic shut is depended upon fluid pressure. When inlet vent is flooded by oil, membrane is moved upward because of negative pressure on upper membrane. In that state, main valve is closed under the function of switch handle. In order to ensure auto-shut performance, the section of vice valve passage is generally smaller, pressure loss being larger. Therefore, the flow of auto-shut nozzle is smaller than that of general nozzle in filling process. Because the vent of auto-shut is communicated with atmosphere in fuel dispenser filling operation, splashing oil may lead to switch off of nozzle, especially in smaller tank. Customer should select appropriate auto-shut nozzle to refuel. Usage and Maintenance During operation light put up and down auto-shut nozzle, regularly add lubricating oil on top level of main v fuel dispenser alve, ensuring that flexible manipulation. Promptly replace invalid components. Pay much attention to passage of auto-shut nozzle, preventing waste jam passages and auto-shut function lost. Although auto-shut nozzle will be closed when container is full, filling person should not leave in case of accident. The failure and troubleshooting of auto-shut nozzle as followed: Table 2-2: auto-shut nozzle failure and troubleshooting Failure Reason(s) Troubleshooting Inflexible auto-shut Waste between membrane and auto control level Open side cover and clean membrane; Disassemble low spout and clean waste Over flexible Waste in air-vent of vice valve Disconnect spout and clean air vent Leakage on top level O-ring is invalid Replace No delivery Vice valve is stuck Disconnect spout and examine vice valve, clean waste and burr Incomplete close Vice valve is stuck Disconnect spout and examine vice valve, clean waste and burr Leakage from close nozzle Main valve overweared or is stuck Disassemble main valve and replace gasket or clean waste Article V Oil indicator Oil in fuel dispenser

because of the Bush administration s misdeeds. In its gentler moments, the administration is sensitive to European touchiness. Americans must be “careful and modest�in telling other parts of the world how to solve questions of identity and religion, says Daniel Fried, the State Department s top man for European affairs. But, in his careful, modest way, Mr Fried makes some firm points about Europe s difficulties in absorbing Muslim newcomers. Europeans, he thinks, are still too inclined to see these Muslims as “unwanted foreigners� In facing a challenge like Muslim immigration, “exclusionary nationalism will not h fuel dispenser elp.�At the same time, Mr Fried fears, some European governments are not very adept at distinguishing between peaceful piety and the more violent kind. He insists that the United States has a “deep and legitimate interest�in the battle of ideas between Islam s moderates and extremists in fuel dispenser all parts of the world—and that it will do its best to support the moderate ones in Europe. Yet, for Europe s angriest Muslims, their host countries gravest sin lies precisely in their alignment with America—both as partners in the global capitalist system and as supporters, in varying degrees, of American foreign policy. So the suggestion that America may have something to teach Europe about how to make Muslims feel more comfortable (and therefore less extreme) looks at first sight rather strange. It is, in fact, by no means absurd. Whatever the defects in Muslim eyes of American foreign policy, the United States has a substantial Muslim population which on the whole seems pretty comfortable there, and has produced some of the world s best Islamic thinkers. That spectacular Middle East-looking mosque at the top of this article is in fact in Dearborn, Michigan. For the same reason as in France—the fact that the state does not like asking questions about religion� the United States has a hard time estimating the size of its Muslim population the guesses range bet fuel dispenser
