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 fuel dispenser 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 known from Formula 2-8 that if A2 / A1 is certain value, P2 be fuel dispenser comes a negative value when velocity of flow increasing a certain extent, that is, P2 smaller than at fuel dispenser

more of us to marry. Good luck POLITICIANS, who tend to be well-meaning but bossy types, find it hard to resist intruding into the private lives of their fellow-citizens, especially when some of those private lives are conducted in a way that troubles respectable society. They meddle at their peril, however. On December 13th John Hutton, the secretary for work and pensions, provided details of the organisation that will replace the failed Child Support Agency. The new body will be called the Child Maintenance and Enforcement Commission and will concentrate on getting money from the most delinquent fathers, encouraging the decent majority to make their own private arrangements. Mr Hutton, who has four children and was divorced three years ago, is threatening to “name and shame�?miscreants on a website set up for the purpose. It will be interesting to see whether it works. That the CSA has been a disaster is not in question. Set up in 1993 with the enthusiastic backing of all parties, who saw it as a way both to save the Treasury money and to force “deadbeat dads�?to meet their responsibilities, the CSA has failed to collect more than £3.5 billion ($6.8 billion) of outstanding payments. Established to police every child-maintenance agreement in the country, it concentrated on the mostly law-abiding middle classes, who would have paid up anyway fuel dispenser , rather than the hard cases, who still didn t. Its clod-hopping approach and serial inefficiencies earned it the hatred and contempt of nearly everyone who had dealings with it, including its own staff. If there is a lesson to be learnt from the CSA fiasco it is that naive attempts by government to get people with chaotic and unstructured lives to behave in the way the rest of us would like them to have little chance of success. It is into this treacherous territory that Iain Duncan Smith is h fuel dispenser oping to propel the Conservative Party.
