of four-piston measurement transducer The upper subassembly includes inlet a fuel dispenser nd outlet of oil. The export axis stretches out of measurement transducer from the hole of upper cover unit. The middle of frame unit is a solid chamber, connecting with four cylinders mounted stainless steel bushing. There is an oblong passage on top of each cylinder, which is communicated with lower part of cylinder. These oblong passages a fuel dispenser lso communicate with annular grooves related on top of frame. Four pistons mounted idler wheels are installed respectively into bushings related, connecting piston with connecting rod at same axes. Camshaft unit insert into the oblong groove in middle of connecting rod. Shaft is supported by installing hole at lower frame and valve seat. D and U bearing are mounted in the two holes. Four end covers are installed at each end of frame, of which adjusting device being installed at one end cover to regulate the moving distance of piston concerned. Adjusting device regulates the discharge of measurement transducer so as to ensure the accuracy. Distributing valve and valve seat are installed at top of frame unit. 1-Seal gasket 2-Upper cover unit/O-ring 3-Drive fork/output shaft 4-Spring\O-ring\valve c fuel dispenser over\seal\gasket 5-Frame\distributing valve\valve seat\connecting rod\cam\cam axis 6-Piston\clamp sheet\pin 7-End cover\adjusting bolt\gasket\regulating wheel Diagram 2-21: Exploded view of four-piston measurement transducer Working principle The pressured oil coming from vapor separator or submersible pump flows into distributing valve via measurement transducer and continuously flow into relevant cylinder via the oblong passage at top of frame so as to drive piston moving. Likewise, the piston impels opposite piston through connecting rod, pressured oil flows out the outlet of upper cover via the passages at top of cylinder and then the inboard window of distributing valve. As piston move to and fro, camshaft is driven by trolley unit that making distributing valve and export axis rotation. W

o pay for their election campaigns. A second reason is that there are more fuel dispenser elections to fight these days. In addition to local-government, European and parliamentary contests, the parties now have to fight elections to the Scottish and Welsh assemblies. “There are now major elections every year, but party funding still follows the general- election cycle,�says Justin Fisher of Brunel University. Instead of build fuel dispenser ing up their war chests to fight a general election every four or five years, the parties now raid them all the time. Campaigning, meanwhile, has become more expensive. Because parties can muster fewer volunteers to canvas door-to-door and lick envelopes, both Labour and Conservatives relied last year on call centres and automated messages. Only a fifth of voters received a visit from someone wearing a colourful rosette, according to the British Election Study. Labour even sent DVDs to undecided voters in target seats. As a result, both parties spent close to the legal limit on their campaigns. The difficulty of matching income to spending in a way that does not make politicians look in thrall to a few wealthy donors has led all three main parties to call for more state funding and a lower fuel dispenser cap on election spending. For the Tories, who argued until recently that state money would be pernicious, this is a significant shift. Andrew Tyrie, the Conservative MP who has shaped the new party line, thinks that large donations make voters suspicious of politicians and also sees changes to the party-finance rules as a chance to reduce Labour s bounty from the unions. But a degree of state support is here already in years when donors are not forthcoming, the main opposition party usually receives about a third of its income in government grants. Which, as Lord Levy knows, is a lot less fraught than having to ask people for money.  © 2006 .  About sponsorship Sport Pay up, pay up and win the game Jul 20th 2006 From The Econ
