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 l fuel dispenser oss 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 filling operation, splashing oil may lead to switch off of nozzle, especially in smaller tank. Customer should select appropriate auto-shut nozzle to refuel.

    arted to go amiss. The economy s formidable performance faltered as GDP growth decelerated from 3.2% in 2004 to 1.8% in 2005, the lowest since 1992. Unlike the slowdown in 2002, which could be blamed on a sharp downturn in world trade after the dotcom crash, the setback in 2005 was mainly home-grown, occurring at a time when the world economy was swinging upward. The economic reverse has cast a lengthening shadow over the labour market. In fuel dispenser the year to February, the number claiming unemployment benefit has risen by 102,000. Last month s increase in the claimant total of 14,600 was the biggest since December 1992, when the economy was clambering out of recession. Mr Brown puts a brave face on the setback. The chancellor argues that the economy has been hit by two shocks, the jump in oil fuel dispenser prices and a slowing housing market. In the past these would have been knock-out blows causing recession but on this occasion they have merely winded the economy. Such resilience should enable growth to pick up over the next three years. In his budget, Mr Brown forecasts that GDP will increase this year by around 2.25%? below the post-war trend rate of 2.5%—but then bounce back to above-trend rates of around 3.0% a year in 2007 and 2008. But this happy scenario will be realised only if the economy s exceptional performance during the past decade proves no longer to be exceptional. Has it become the new norm? Two significant improvements are indeed structural. First, low inflation has become ingrained in people s expectations. This both makes it easier for the Bank of England to steer the economy and helps businesses as they plan and invest for the future. fuel dispenser Second, despite too many burdensome new regulations on employers under the Labour government, Britain s labour market has not returned to the bad old days. Unions, which have continued to haemorrhage members outside the public sector, are a waning force in the private economy, unable to call the shots in pay bargaining. Both these structural ch
