    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 pulse 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 positio fuel dispenser n 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 fuel dispenser 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.

    etween the 12 cities that are staging matches. Germany s enduring ability to make the trains run on time should impress visitors. Businessmen and investors, however, may be impressed by something else that Mr Mehdorn has done with Deutsche Bahn. He has taken a huge state-owned railway system, successfully diversified it into other related businesses, and made it profitable. The managers of America s fuel dispenser famously troubled Amtrak system, or of Britain s controversial privatised railways, would love to be able to say the same. Running Deutsche Bahn has been one long battle for the pugnacious Mr Mehdorn. A stocky Berliner, his goal was to turn the Bahn from a hea fuel dispenser vily subsidised, state-owned railway into a self-financing “mobility provider� His style has made him unpopular with some politicians—the mayor of Berlin recently accused him of planning a “deal made in the madhouse�with the City of Hamburg. But his unfussy bluntness has also won admirers. Despite the halving of the company s workforce over the past 11 years, he is regarded as a boss who cares. It helps that his pay� rumoured to be ¬650,000 ($767,000) a year—is modest by fat-cat standards. He also has little time for elaborate public relations. He makes no secret of his love for driving—cars not trains—and says frankly that if it makes more sense to take the plane than the train, that is what he will do. Mr Mehdorn s adventures with Deutsche Bahn began when he joined as chief executive in 1999, after a career at engineering firms. Through a strategy of acquisition and diversification, he has transformed the group into Europe s biggest rail-freight operator, Germany s biggest bus operator, and the world s number two in airfreight and number three in sea-freight. Deutsche Bahn has just bought Bax Global, an American logistics firm, for $1.1 billion, adding it to Schenker and Stinnes, two German logistics firms which Mr Mehdorn acquired in 2002. The firm is also making more imaginative use of its own technology—it is h fuel dispenser
