    scharge, turn anticlockwise to increase discharge; reassemble hand wheel pin and lead-seal it after adjustment. Common failure and Troubleshooting The main failure of four-piston measurement transducer includes outside leakage and accuracy decline. As appear outside leakage, all seal sections should be inspected. Generally, failure will be solved through removing damaged or aging sealed components. Diagram 2-22: working principle of four-piston measurement transducer Through long time of operation, the accuracy of measurement transducer is declined due to fuel dispenser various abrasion occurred on cam, ideal wheel, distributing valve, valve seat, and piston. From start, regulating adjusting wheel makes the accuracy meet the requirements about national metrology appraisal. If still can’t reach the wanted accuracy, some abrasion examinations should be conducted, including components of piston, distributing valve and valve seat. These components surfaces are fragile to be scratched by hard grain, increasing inner leakage and accuracy decline. If appear above situation, replace piston or grind the surfaces of distributing valve and valve seat. Double soft piston measurement transducer The article will introduce the structure, working principle and maintenance. Structure This type of measurement transducer has two soft pistons, smaller than four-piston type. Appearance and partial cutaway view is illustrated in Diagram 2-23, structure and key components in Diagram 2-24. Dia fuel dispenser gram 2-23: Cutaway view and figure of four-piston measurement transducer It has two pistons formed a 120 degree angle, driven by connecting rod that force crankshaft moving. Component cylinder is installed in parallel. The two rolling bearings respectively installed on connecting rod and crankshaft reduces the friction. The end of connecting rod contacts with bushing. The oil discharge is controlled by distrib fuel dispenser uting valve that communicating with inlet and outlet. On the top of distributing valve mounted a bearing used for installing cranks

    uses wholly disproportionate force to subdue a tiny and poorly equipped Papuan independence movement. All this has left most Papuans at best distrustful of Jakarta and more often wanting to secede from Indonesia. The division of the territory into two provinces in March, despite widespread local opposition, has exacerbated tensions. In fairness to Indonesia s government, Papuan activists claims of genocide lack credibility. But Mr Yudhoyono s policy of severely restricting access to the region by diplomats, researchers and journalists means that such alle fuel dispenser gations cannot be completely discounted. Hopes that Papua will follow Aceh, the Indonesian province blighted by rebellion for 29 years and now on the road to peace, are thus fading fast. And hopes for a restoration of good relations with Australia look little healthier. © 2006 . Mapping China, badly No direction home Apr 20th 2006 | BEIJING From The Economist print edition When state secrecy meets modern motoring FROM May 1st, millions of Chinese will enjoy a week s holiday. But many of those planning to drive long distances or hike in the countryside will get lost. The hectic pace of urban construction and road building combined with a culture of secrecy makes Chinese maps unreliable and vague. Detailed topographical maps of the kind commonly used by ramblers in other countries are strictly classified. Schoolchildren get no training in how to read them. Two ye fuel dispenser ars ago government cartographers in north-eastern China said some local government websites had “seriously threatened national security?by displaying secret maps with contours, elevations and grid lines. But the internet and the spread of satellite-navigation technology are beginning to weaken the state s control of cartographical detail. Chinese officials were horrified last year when they discovered t fuel dispenser hat users of Google Earth, a free satellite-imaging facility, could direct the software to display buildings inside Zhongnanhai
