haft. The spring between top cover and distributing valve is used for enforcing sealability. The two gears synchronous to crankshaft moving transmit rotation number into pul fuel dispenser se sensor. Working principle This type measurement transducer is similar to a set of hydraulic motor, which is driven by pressured oil. Thus, the discharge is corresponded to the crankshaft rotation. As distributing valve’s position is certain when oil flowing into measurement transducer, the piston discharge or inflow also is constant. Pistons depend upon the different oil pressure of inflow and discharge to move, which form a shuttle movement. The above two pistons movements create a third cylinder, which also has a 120 degree angle. The dynamic working circulation is showed in Diagram 2-25. As the diameter and moving distance of piston is certain, the relation between movement and crankshaft rotation also fixed. In every two times inflow or discharge of piston, crankshaft turn around a circle, oil volume in inlet or outlet progress is constant. 1-Piston 2-Crankshaft 3-4-Connecting rod 5-Screw 6-Bearing 7-Bushing 8-Frame 9-Distributing valve 10-Top cover 11-Bearing 12-Spring 13-14-Gear 15-Adjusting bolt 16-T-shaped key 17-Sider cover Diagram 2-24: Structural drawing of four-piston measurement transducer Diagram 2-25: Working principal drawing This type of measurement transducer includes 1L circulation discharge and 0.5 L circulation discharge，selecting according to wanted discharge of fuel dispenser. Discharge adjustment Over a long period of operation the accuracy of measurement transducer declined due to either parts abrasion or large change in oil temperature and viscosity. Therefore, regulative device often used to adjust the accuracy within the stipulated scope of national metrology appraisal. The following procedure is conducted as measurement accuracy decline.

y of different sectors of the economy (much as the oil shocks of the 1970s did). Mr Gordon sees the underlying rate of business productivity growth slowing to below 2.5 fuel dispenser % which, by his calculations, implies a rate of 2.1% for the overall economy. Coupled with the slowdown in labour supply, he concludes that America s potential growth rate could fall to 2.5%. Although their predictions for productivity and labour supply are different, JPMorgan s economists agree with his figure. Mr Gordon s calculations suggest that 2.5% would be America s slowest economic speed limit in over a century (see chart 2). That is less surprising than it sounds. Though the statistics are less reliable for the years before 1950, it seems that in the early 20th century potential output grew rapidly thanks both to technological innovation and rapid immigration. Although actual output tumbled during the 1930s, America s potential growth rate did not. Some scholars argue that the 1930s were among the most technologically innovative years of the century. Since no one foresaw the productivity revolution of the mid-1990s, these predictions could prove too pessimistic. The next “killer application�could be just around the corner. Even without rapid investment, the IT revolution may yield more productivity gains. But without some such happy chance, it looks as though America s potential growth rate is heading for a slowdown, at least for the next few years. The sooner that investors and policymakers wake up to this, the smoother the adjustment is likely to be. * “The recent decline in the labour force participation rate and its implications for potential labour supply� by Stephanie Aaronson, Bruce Fallick, Andrew Figura, Jonathan Pingle and William Wascher.
