e, low cost and convenient maintenance, vane pump is widely adopted in many industrial areas. Most of domestic manufacturer of fuel dispenser install vane pump as component. Vane pump includes ration pump and variable pump, the former is mounted in fuel dispenser. At recent years, the domestic noise research for vane pump has been achieved good progress conducted by fuel dispenser manufacturer. The noise of vane pump has remarkably been downed, reaching to less than 70 d B. it is introduced as followed: 1: Cap nut 2: Adjusting bolt 3: Sp fuel dispenser ring seat 4: Spring 5: Blade 6: Rotor 7: Plug 8: Spring flake 9: Axis 10: Frame 11: Overflow valve 12: Valve seat Diagram 2-1: Vane pump structure drawing Structure and working principle of vane pump The Diagram 2-1 and 2-2 illustrate one kind of vane pump about its structure and tridimensional exploded drawing. This kind of pump prevails in domestic fuel dispenser market. Its structure, principle and maintenance will be introduced. Vane pump consists of overflow valve and vane pump illustrated in Diagram 2-1. Overflow valve is installed on the upper of body, including overflow valve seat, vale core, spring, spring bracket, jointer, adjusting bolt and cap nut. The lower body is pump section composed of gliding bearing, rotor subassembly, blade set, spring flat and pump cover with gliding bearing. The right side of diagram is inlet, the opposite outlet. The working principle, performance and common troubleshooting of vane pump and overflow valve will be presented respectively. Vane pump section The chamber in where rotor installed is pump chamber, its installing procedure showed in diagram 2-3. A cen fuel dispenser trifugal degree e between the center of chamber and rotor is illustrated in diagram. There are upper and down seal area, high pressure and low pressure transitional area, divided by the center of rotor. The angular degree in sealing area is larger than that of degree formed by the neared two vanes so as to prevent oil flow between low and high pressure areas. 1-Cap fuel dispenser

But Helmut and Jacques, they re not THEY are Europe s odd couple she, the cautious anti-communist physicist, who wants the European constitution but says economic reform can be delayed; he, the animated former Maoist turned law professor, who bangs on about economic reform but says that the constitution should be postponed. Mismatched as they may seem, Angela Merkel, the German chancellor, and José Manuel Barroso, the European Commission s president, have struck up the most important political relationship in the European U fuel dispenser nion. On successive days last week, the two gave speeches about the EU that could have been planned in concert, with an eye on the first half of next year when Germany takes over the presidency of the EU. Both called for more work on the constitution, albeit with differing degrees of urgency; less red tape; and more consumer protection. If anybody is directing the EU (admittedly, a big if), it is this pair from Germany and Portugal. Their partnership has come about faute de mieux. True believers in European integration always whinge about “lack of leadership�? but that lack is palpable right now. Only 26% of British voters approve of the job Tony Blair is doing as prime minister, making him the least loved Labour prime minister since the war. Barely a fifth of French voters approve of Jacques Chirac s performance as president. These levels of support would discourage any sane politician from reopening the contentious issue of the EU constitution in France or Britain. In Italy Romano Prodi has gone from narrow electoral victory to popular disenchantment without even the intervening stage of forming a fuel dispenser government. The Polish coalition has brought in a virulently anti-European populist party to shore up its majority. The Dutch are still looking inwards. With Euroscepticism growing in almost every EU member, no leader besides Ms Merkel has the political capital to take risks for the sake of wider Europe. But Ms Merkel and Mr Barroso have more in common than fuel dispenser
