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 flowage formula is showed in Diagram 2-1.

and American Exceptionalism�? argues that Europeans are in a mood of “constant irritation�?when it comes to America and football. Americans, they grumble, either fail to embrace the “beautiful game�?or, when they do, get it wrong. How dare they turn it into a women s game! And how dare they insist on calling it “soccer�? Germany has been in high dudgeon for months over the fact that the national coach, Jürgen Klinsmann, is an Americanophile who lives in Los Angeles and has employed American fitness-trainers and a psychologist to help prepare the team. The offside rule Behind all this lies a bigger debate about America s cultural idiosyncrasy. Americans like to think of themselves as global trendsetters and standard-makers. But a raft of opinion polls since the Iraq war have demonstrated that America is not so much a trendsetter as an outlier—more individualistic, more religious, more nationalistic, more anti-government and more gung-ho about the use of force than other countries. This evidence of American exceptionalism has provoked a fierce debate within the United States between “red�? Americans, who are proud of their country s oddness, and “blue�?Americans (mostly Democrats), who think that America should pay more attention to the rest of the world. It has also provoked an even fiercer backlash in other countries against America s “weird�?values, such as its support for the death penalty and its predilection for unilateral action. It is possible that American exceptionalism may wane in the next few years, particularly if the Democrats can recapture the presidency. Unilateral action is out of fashion, thanks to the Iraq mess. But when it comes to sport, American exceptionalism looks more enduring. It is hard to imagine America s indigenous sports being forced to cede much ground fuel dispenser to soccer, short of a dramatic victory by the national team in July; and it is impossible to imagine the rest of the world abandoning their beloved footballs for pigskins or bas fuel dispenser fuel dispenser
