    ystem. The valve core of overflow valve moves outward so that all pressured oil flood past the outlet of overflow valve and flow into suction chamber, realizing oil circulation in pump. The hydraulic system pressure is adjusted through increasing or reducing spring pressure. The most fragile section in hydraulic system will be damaged as the pressure reaching a certain value without a overflow valve to control pressure. The spring pressure will be increased through to add the thickness of pre-pressure ring (20a). The pressure to open overflow valve and the delivery volume of fuel dispenser are also increased. Vice versa, as the thickness is reduced. working principle of inner-cycloidal gear pump Inner-cycloidal gear pump consists of a pair of inner and outer gear joggled interactively. Inner gear is driver, called as inner rotor; outer gear is driven called as outer rotor. The figure of inner rotor is round arc curve, but the joint section of inner rotor figure and outer rotor curve is exterior cycloidal. Outer rotor exceeds one tooth than inner rotor. Sever sealed working cubage are formed between teeth of inner and outer rotor. Inner rotor brings outer rotor rotation anticlockwise. At that time the cubage gradually increase, formed in suction chamber by the tooth top of inner rotor and gear vale of outer rotor. As pressured oil suck into discharge fuel dispenser chamber the cubage formed by inner and outer gear is reducing, impelling oil out of pump. Continual suction and discharge result from the unceasing rotation of out gear driven by inner gear. 1-Vapor separator frame 2-Filter bracket 3-Filter 4-Filter bracket 5\6-O-ring 7-Gear group 8-Axis 9-Key 10-Cover 11-Oil seal 11a-Bolt 12-Screw 13-Elastic washer 14-Thread pipe 15-Joiter 16-Inlet filter 17-Stainer cover 18-Seal ring 19-Voverflow valve cover 20-Spring 20a-Preloading ring 21-Voverflow valve 22-Overflow valve 23-Filter with valve 23a-Spring 24-Exhaust pipe jointer 25-Screw 26-Outlet pipe 27-O-ring 28-Pump body Diagram 2-9: One kind of inner cycloida fuel dispenser fuel dispenser

    er showed that India had overtaken China in new subscribers per month for the first time. India still lags behind China in total subscribers, with a mere 136m (up from 75m a year ago), compared with China s 449m. But India s government is confident that this gap can be quickly closed, and that it will meet its target of 500m phone subscribers by 2010. The boom has become the source of much national pride. It is arguably a more widely celebrated example of the “New India?than the high-tech offshoring industry centred on Bangalore, because poorer Indians are participating in it too. Industry bosses are quick to point out that the spread of mobile phones is bringing labourers, farmers and fishermen into the economic mainstream. “An unemployed person with a phone suddenly feels part of the nation,?says one top executive. The mood change is striking because, not long ago, the phone system was weighed down by the stifling bureaucracy that was India s “Licence Raj? The introduction of mobile phones was initially hampered by overly complex regulation. As a result, India had one of the world s lowest phone penetration rates at the start of this decade—all the more shocking given the country s lively democracy and its people s love of conversation. But the government eventually cleaned up the mess, and its most significant contribution to the en fuel dispenser suing boom has been to keep out of the way. Duties and tariffs on telephone services have been rationalised, and the government has also eased restrictions on foreigners. In October AT&T became the first foreign telecoms firm to win a licence to operate freely in India, following a cut in licence fees and a legal change that allows foreign firms to own up to 74% of their Indian subsidiaries. Britain s BT is applying to offer domestic and international long-distance services in India, from which it expects revenues of $250m by 2009. Foreign capital will be essential if the industry is to build the infrastructure needed for continued growth fuel dispenser fuel dispenser
