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.

Influential Catholics warned that they may not accept the results of the poll; riots rocked Kinshasa, the capital; more civilians were killed in the lawless east; and a stone-throwing crowd jeered President Joseph Kabila as he arrived to campaign in a southern opposition stronghold. But, with a few days to go, it seemed as though things would just about hold together enough for the poll to take place, as planned, on July 30th. The Congolese should be able to choose their leaders freely for the first time in over 40 years. AFP Vote for the winner It will not be perfect by a long way; there have been too many glitches, too many accusations of intimidation and vote-rigging, for that. A simmering row over why quite so many spare ballot papers�?m of them—have been printed, on top of the 26m required for those registered to vote, will not go away. Pessimists fear the extra ballots will be used to rig the vote. The electoral commission, however, says they will be used only to replace those lost or destroyed, and can be tracked. News that the details of about 1.3m voters have gone missing and that their names will not be on the register on voting day has gone down badly too. Organisers say they will be able to let these people vote, but such problems will fuel mistrust in the official results. Catholic leaders told worshippers in packed churches in Kinshasa on July 23rd, the Sunday before the poll, that they should boycott it if such issues cann fuel dispenser fuel dispenser
