    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. Thu fuel dispenser s, 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 fuel dispenser 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.

    About sponsorship Fat of the land Mar 23rd 2006 From The Economist print edition But only for a select few IN PINGGU district, a mountainous and largely rural area in north-eastern Beijing, local officials are keen to show off how they are implementing one of the Communist Party s fuel dispenser latest directives. It is, like all party initiatives, encapsulated in a slogan “Promote the construction of a new socialist countryside.�The idea is to narrow the widening gap between rural and urban China, defuse unrest and turn the country s 800m rural residents into economy-boosting consumers. In Bolitai Village, perched on a slope beneath the scenic ruins of the Great Wall, building a “new socialist countryside�has meant bulldozing peasants decrepit houses and replacing them with cheery-looking two-storey villas with solar heating panels on the roofs and broadband internet access. Pinggu s plan is to enrich remote village communities by turning them into weekend hideaways for a new middle class in Beijing that now has cars and thus the means to roam. The government provides grants and arranges low-interest loans for construction, and encourages lots of official delegations to visit. The revamped Bolitai looks garishly new, and insofar as it involves an entire community falling in with a government-inspired project (barring one old man who has refused to rebuild his house), it has the feel of Chinese socialism. Pinggu officials boast that their “new socialist countryside�campaign got started before the idea became party policy fuel dispenser last October. The party plans to boost spending on rural infrastructure including roads, schools and hospitals, abolish all school fees by the end of next year and step up efforts to provide peasants with health insurance. But none of this will tackle the root of China s rural problems the ownership of land. Reports of large-scale and sometimes violent rural protests have become ever more frequent in recent months.
