of four-piston measurement transducer The upper subassembly includes inlet and 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 also 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 fuel dispenser 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 cover\seal\gasket 5-Frame\distributing valve\valve seat\con fuel dispenser necting 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 fuel dispenser

nt memory. By the end of the year, GDP is forecast to be rising by an above-trend 3% a year, a pace sustained through 2007. Yet the central projection for consumer-price inflation shows it glued to the government s target of 2% a year. The Bank s projections are based on market expectations of interest rates, which are broadly flat over the next couple of years. The report thus implies that the base rate is, boringly, likely to remain at 4.5%, where it has been held since last August s evidently over-sensational quarter- point cut from 4.75%. The outlook appears so tediously benign it verges upon the panglossian. No doubt that was why Mr King was keen to highlight the risks when presenting the report on February 15th. These are on the downside for growth, he said, but “evenly balanced�for inflation. The central growth forecast certainly looks quite punchy, although the Bank has in fact lowered it a bit for 2007 since it last ventured a prediction in November. Much depends upon the consumer, whose reluctance to spend last year pulled GDP growth down. Th fuel dispenser e Bank now expects household spending to grow by close to its long-term average over the next three years. This could prove too optimistic, now that the housing market has become much less frothy and peopl fuel dispenser e are being urged to save more for their retirement. If growth is lower than expected—and the Bank concedes that consumer spending could turn out to be weaker than in its central projection—the effect will be to pull down inflation. But set against this are possible risks that could push inflation up, notably the longer-term impact of higher energy prices. The evidence so far is encouraging. In marked contrast with previous oil-price shocks, the sharp jump in fuel bills has not fed through to big wage demands. Official figures released on February 15th showed that pay growth remains well under control. Average earnings, excluding bonuses, rose by 3.8% in the year to the final quarter of 2005. One reason why pay pressur fuel dispenser
