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.

weeks, shorts and T-shirts have steadily taken over from suits and ties as the dress code in 10 Downing Street. A sign of creeping demob happiness or just a lack of air conditioning? Probably a bit of both. As the prime minister packs his bags for a brief trip to America before beginning his summer holiday, there is a distinct feeling that when he returns the countdown to his departure will begin in earnest. These are strange political times. Tony Blair s energy and appetite for the job is undiminished. According to those who see him daily, he is unfailingly cheerful. Such is his sense of purpose that he refuses to be distracted even by the increasingly menacing police investigation into party funding. Yet a thoughtful speech this week on public-health policy, the second of a series he is giving on domestic issues, inevitably had a valedictory ring to it. A part of Mr Blair believes power is such a precious commodity that it should never be given up willingly. But everything now suggests that he has settled for a dignified exit, instead of waiting for his fingers to be prised one by one from the Downing Street door. On the not entirely safe assumption that the police fail to find evidence to support charges that Labour s fundraisers sold peerages, it is now hard to imagine circumstances in which Mr Blair would not go around the middle of next year. The most p fuel dispenser lausible scenario is that he will announce his departure on May 2nd, his tenth anniversary as prime minister and on the eve of elections to the Scottish Parliament, th fuel dispenser e Welsh Assembly and councils up and down the land. If Gordon Brown has to dispose of a challenge from the left, Mr Blair will probably not take his final bow until the G8 meeting in June. Most of the MPs who left Westminster this week for the long recess would prefer a less drawn-out timetable. This is not so much a reflection on Mr Blair as a yearning for the political fight to begin in earnest, which cannot happen until Mr Brown takes over. Anticipation is probably fuel dispenser
