A Section and B Section are the neared vane, which rotate together with rotor clockwise. The turning Vane A increases the cubage of low pressure transitional area, oil being sucked into pump. Fuel between vane A and Vane B is brought to high pressure transitional area as the vane go around clockwise. In high pressure transitional area cubage become smaller because of vane rotation, as result, oil is impelled out under the vane pressure. When rotor turns continually oil in tank is sucked into pump and then discharged out ceaselessly to form a stable flowage. Pump fuel dispenser flowage formula is showed in D fuel dispenser iagram 2-1.

tution. The presidency has started to develop some features of greater permanence, which could be nudged along. The EU showed last December that it is capable of setting budgets over the next seven fuel dispenser years without a constitution (admittedly, the budget was a dog s dinner, but that is another matter). Anyway, the efficiency of the system is not decisive. Like most big governmental structures, the EU is not designed to be efficient; it is meant to be constrained by checks and balances. Equally, the constitution cannot solve the EU s growing problems over enlargement. Support for bringing new countries into the club is ebbing both at the popular and the governmental level�? despite a mass of evidence that existing members have benefited as much as new ones from previous expansions. (This week, a study from the European Commission concluded that there has been no significant loss of jobs to the east, and that increased trade has raised incomes everywhere.) In some ways, indeed, the constitutional debate has become a way of avoiding a debate over enlargement. As originally planned, it would have been agreed before the new fuel dispenser members from central Europe h fuel dispenser ad established real influence inside the club. This suggests that a better way to deal with enlargement fatigue might be to keep advertising the benefits of expansion (national governments must do this, as well as the commission), and guard the credibility of the process more carefully. The commission is about to pronounce on whether it thinks Romania and Bulgaria have met all the criteria for accession next year. If Bulgaria (say) has not, it would be best if the commission said so. Avoiding the C word If all this is true, why do governments insist on still discussing the constitution? The answer may be that they believe a continuing debate over the subject is the best hope for reversing a growing public disenchantment with the entire European project. Yet there is not much evidence to support any such belief. In popular votes, the cons
