ystem. The valve core of overflow valve moves outward so that all pressured oil flood past the outlet of overflow valve and flow into suction chamber, realizing oil circulation in pump. The hydraulic system pressure is adjusted through increasing or reducing spring pressure. The most fragile section in hydraulic system will be damaged as the pressure reaching a certain value without a overflow valve to control pressure. The spring pressure will be increased through to add the thickness of pre-pressure ring (20a). The p fuel dispenser ressure to open overflow valve and the delivery volume of fuel dispenser are also increased. Vice versa, as the thickness is reduced. working principle of inner-cycloidal gear pump Inner-cycloidal gear pump consists of a pair of inner and outer gear joggled interactively. Inner gear is driver, call fuel dispenser ed as inner rotor; outer gear is driven called as outer rotor. The figure of inner rotor is round arc curve, but the joint section of inner rotor figure and outer rotor curve is exterior cycloidal. Outer rotor exceeds one tooth than inner rotor. Sever sealed working cubage are formed between teeth of inner and outer rotor. Inner rotor brings outer rotor rotation anticlockwise. At that time the cubage gradually increase, formed in suction chamber by the tooth top of inner rotor and gear vale of outer rotor. As pressured oil suck into discharge chamber the cubage formed by inner and outer gear is reducing, impelling oil out of pump. Continual suction and discharge result from the unceasing rotation of out gear driven by inner gear. 1-Vapor separator frame 2-Filter bracket 3-Filter 4-Filter bracket 5\6-O-ring 7-Gear group 8-Axis 9-Key 10-Cover 11-Oil seal 11a-Bolt 12-Screw 13-Elastic washer 14-Thread pipe 15-Joiter 16-Inlet filter 17-Stainer cover 18-Seal ring 19-Voverflow valve cover 20-Spring 20a-Preloading ring 21-Voverflow valve 22-Overflow valve 23-Filter with valve 23a-Spring 24-Exhaust pipe jointer 25-Screw 26-Outlet pipe 27-O-ring 28-Pump body Diagram 2-9: One kind of inner cycloida fuel dispenser

tary elections, after police had blocked the doors to opposition supporters; and of the candidate who was runner-up in the presidential contest, Ayman Nour, being put behind bars for five years on a flimsy forgery charge that many Egyptians interpret as punishment for daring to present a liberal alternative to 77-year-old President Mubarak, who is now set to rule until 2011. Yet if Egypt looks very much the same top-heavy, police-ridden state as it has since the 1952 coup that ushered in what some describe as a pr fuel dispenser esidential monarchy, much has changed below the surface. The most populous (70m- strong) Arab country, and in many ways the most influential, is clearly in a phase of transition, though no one seems to know towards what. The clearest portent for some is the dramatic advance of the Muslim Brotherh fuel dispenser ood. Though officially banned, Egypt s oldest Islamist group won most of the parliamentary seats it contested in November. Probably fearing an Algerian-style government response should they have done too well, the Brotherhood fielded candidates for just 141 out of 444 seats, yet it emerged, with 88 MPs, as the biggest opposition block to sit in an Egyptian parliament since the last king s removal. Such electoral success was partly a reward for the Brotherhood s formidably efficient organisation, as well as for its adoption of a more inclusive message that stresses democratic freedoms rather than enforced Islamisation. But it also reflected widespread public anger with the regime, as well as the state s diminished capacity to control the press, trade unions and other public forums. The Brotherhood may have captured the same kind of popular will for change that has fostered secular movements in such places as Serbia and Ukraine. The ruling National Democratic Party s candidates lost two-thirds of the races they ran in, despite widespread rigging. The party kept its traditional rubber-stamp majority by coaxing scores of “independent�winning candidates to join, largely in the hope of ge fuel dispenser
