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

s (ie, after allowing for inflation) have been negative for the past two years and even now are barely positive (see chart). In other words, monetary policy is still stimulating demand. A super-loose policy was necessary when there was a risk of deflation, but not now. It therefore makes sense to nudge rates gradually back to more normal levels. Most economists think that the “neutral�?rate of interest, which would neither stimulate nor restrain demand in the euro area, is now more than 3% (in nominal terms). fuel dispenser The ECB is also more confident that economic growth is picking up. GDP figures are like a glance in the rear-view mirror they tell you where the economy has come from, but not where it is or where it is going. Experience also suggests that first estimates of GDP growth are almost always revised upwards. This is why policymakers now pay close attention to surveys of business and consumer confidence. The index of German business confidence calculated monthly by Ifo, a Munich research institute, is at its highest since the post-unification boom in 1991. If the index s past relationship with GDP held, it would signal growth this year of 3-4%. Admittedly, businessmen s glee partly reflects their optimism about global growth prospects and their fuel dispenser profits are benefiting from production in low-wage countries. This may make the Ifo index a less useful guide to domestic economic prospects than it used to be. Nevertheless, the surge in the index is not confined to Proudly Produced by nEo  manufacturing in particular, retailers are more confident than they have been for six years. Surveys of German consumer confidence have also perked up this year. Germany, however, is not the who fuel dispenser le zone. Some economists think that Germany is growing largely at the expense of its euro-area neighbours, thanks to improvements in its competitiveness. If that were right,
