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 pr fuel dispenser ocess. Because the vent of auto-shut is communicated with atmosphere in filling operati fuel dispenser on, 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 valve, 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.

American praise, with strings attached DID he get what he wanted? This week Ehud Olmert went to Washington, DC, for his first meeting as Israel s prime minister with George Bush (they had met before as mayor of Jerusalem and governor of Texas). The visit looked like a roaring success. Mr Olmert spent plenty of time with the president and enjoyed the rare honour of addressing Congress. The two leaders said they shared the same view about the need to stop Iran acquiring nuclear weapons. Mr Bush repeated a promise that the United States would fuel dispenser “come to its aid�if Israel were attacked. To top it all, Mr Bush praised as “bold�M fuel dispenser r Olmert s plan to adjust Israel s borders unilaterally if attempts to do so by negotiation with the Palestinians came to naught. Mr Olmert, a perfect guest, expressed his effusive appreciation. But whether he really got all he wanted is hard to say. He told Congress that a nuclear-armed Iran would pose “an existential threat�to the Jewish state. He may have received private reassurances from Mr Bush that Iran would somehow be stopped. But a vague American promise to defend Israel will not quieten mounting anxiety back home. Indeed, Mr Bush s defence guarantee may have been designed as much to restrain Israeli actions—whether a pre-emptive strike, or a change in its own policy of nuclear ambiguity—as to deter Iran s. By the same token, Mr Olmert has not yet received everything he once hoped for from Mr Bush on the Palestinian front a diplomatic green light, and practical help, for his plan to abandon Israel s outlying settlements in the West Bank and incorporate the main Jewish settlement blocks in new borders that America would endorse as final. Mr Bush welcom fuel dispenser ed Israel s unilateral plan as a step towards a two-state solution if Hamas, the Islamist government of the Palestinian Authority (PA), sticks “in the period ahead�to its refusal to recognise Israel s right to exist or to renounce violence. But first Mr Bush wants Israel to try to n
