ds of gear pumps. The following introduce cycloidal gear pump: Diagram 2-8: Two kinds 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 direction. Delivery pressure depends upon the adjustment 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 fuel dispenser 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 pres fuel dispenser sure 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 swit fuel dispenser ch 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

raised this week, after Ayatollah Khamenei, the supreme spiritual leader of Iran, which holds great sway with Shia parties in Iraq, agreed to discuss the situation there with America. But no Iraqi government could end the violence soon the country contains too many unsettled scores and too many angry people. Neither success nor failure is certain, but any improvement will be slow. On a toilet-wall in an American airbase in western Iraq, an American soldier has scrawled his own summary analysis “We came, we saw, we wasted a year of our lives. At least we got the fuckers to vote.� © 2006 .  About sponsorship Press freedom in east Africa Hear no evil Mar 23rd 2006 | ADDIS ABABA, ENTEBBE AND NAIROBI From The Economist print edition The reasons for our correspondent s explusion from Uganda FOLLOWING the victory of Yoweri Museveni in the recent presidential election in Uganda, this newspaper s correspondent there, Blake Lambert, has been thrown out of the country. Apart from being bad news for Mr Lambert, a Canadian who had sp fuel dispenser ent nearly three years reporting from Uganda for The Economist and others, it is even worse news for Ugandan journalists. The message to them is clear any reporter picking at the competence of Mr Museveni s administration can expect something rather nastier than a brusque cheerio at Entebbe airport, such as Mr Lambert experienced. As a government minister warned the assembled corresponden fuel dispenser ts at a press conference to explain Mr Lambert s expulsion “You are vulnerable people in this country. In case of any trouble caused as a result of bad reporting, you will not be spared.� Mr Lambert says that the Canadian authorities seemed unconcerned by his expu fuel dispenser lsion. But a series of complaints from other diplomats forced the Ugandan government to offer reasons for his removal. They gave three. One is that he had no valid work permit, a Kafkaesque charge since the permit was dependent on a press
