    ds of gear pumps. The following introduce cycloidal gear pump: Diagram 2-8: Two kinds fuel dispenser of internal gear pumps Gear pump structure Diagram 2-9 is an exploded drawing for inner cycloidal gear pump. Inner cycloidal gear pump mainly composed of frame, gear-group, overflow valve, strainer, pump cover subassembly, etc. pump chamber is cylinder-shape in which strainer is installed at inlet of oil. Overflow valve and pump is in parallel connection. Concentric installation is between pump chamber and exterior gear-group, between inner gear and principal axis. But inner gear and outer gear is assembled centrifugally. Principal axis drives gear-group rotate. Gear pump has two chambers --- pressure oil chamber that discharge oil and suction chamber that suck oil—which are not connectable. When gear pump operating gear-group rotate anticlockwise at view of pump cover dir fuel dispenser ection. Delivery pressure depends upon the adjustm fuel dispenser ent of overflow valve, laden degree and inner penetration. In the process of nozzle open, small oil resistance, overflow valve is in low status of openness. However, as nozzle turn down or large oil resistance and pressure, the spring of overflow valve move sideward, increasing openness so that more oil flow into negative chamber. The outlet pressure of pump keeps under 0.3Mpa. Working principle of overflow valve The outlet of overflow valve is the interface in where pressured oil chamber pass into suction chamber. The overflow valve play role as a protection to restrict the highest pressure in hydraulic system and to adjust delivery volume of fuel dispenser. Its structure is illustrated in Diagram 2-9. Motor driving pump starting work, the pressured oil from pressure area flow into vapor-separator and overflow valve outlet via pump outlet. Given switch nozzle, part of oil flow out of pipe of vapor separator, another part of oil flow into suction chamber via overflow valve with small openness. However, as close down nozzle, pressured oil overcome spring bounce under high pressure in hydraulic s

    charges were it not for his presidential immunity. The army, which used to be highly polit fuel dispenser icised, is still believed to be a bastion of support for the opposition Nationalist Party, the Kuomintang (KMT). But there has been no hint of any military pressure on the president. Corruption allegations against Ma Ying-jeou (pictured above right), the KMT s chairman and present mayor of Taipei, surfaced in November, and helped deflect criticism from Mr Chen. The president s Democratic Progressive Party (DPP) is widely expected to lose the race for the Taipei mayorship to the KMT s Hau Lung-bin (above left). But opinion polls suggest the DPP s candidate, Frank Hsieh, still enjoys the support of traditional DPP voters in the capital. In Kaohsiung, a port city in the south, the contest is far closer. Mr Ma s travails appear to have boosted the chances of the DPP s Che fuel dispenser n Chu, who spent six years in jail during the aut fuel dispenser horitarian era for her role in pro-democracy protests in Kaohsiung in 1979. Losing in Kaohsiung would be a setback for the DPP. But the city has never been a DPP stronghold. Votes usually split quite evenly. Half go to the DPP and other parties that likewise back Taiwan s formal independence from China, which still claims sovereignty. Half go to the KMT and others arguing for closer ties with China. Dachi Liao of Kaohsiung s National Sun Yat-sen University says both big parties have in fact been overstating the importance of these polls in order to rally supporters. Even if the KMT wins, Mr Chen is unlikely to waver in his apparent determination to stay in office until the end of his term in May 2008. Regardless of the outcome, the DPP will face big internal struggles as it prepares for the presidential elections. Choosing a candidate will be divisive. Possible contenders include Frank Hsieh as well as Su Tseng-chang, the prime minister, Yu Shyi-kun, the party s chairman, and Annette Lu, the vice-president. Mr Yu and possibly Mr Su would face pressure to resign should the DPP lose bo
