As their structure and performance vary largely, the handbook will not introduce them one by one. Some failure and trouble occurred during operation should be solved in accordance with the maintenance explanation provided by manufacturer. In order to ensure operation security difficult problem occurred should be inspected and repaired by the professional technician exper fuel dispenser ienced or maintenance artificer sent by manufacturer in case of bringing accident. Article II Vapor Separator The main function of vapor separator is segregated vapor from oil and discharge so as to ensure accuracy of measure transducer under no foam condition. The principal technical indicator guideline of vapor separator is the capacity to segregate vapor and keep stability. 1-Upper cover 2-Exhaust valve seat 3-Exhaust pipe 4-Float 5-Fuel return valve 6-Frame 7-Ball-float 8-Strainer 9-Spring seat 10-Check valve 11-Check valve seat 12\13-Outlet pipe 14-Gas outlet valve Diagram 2-12: Structure cutaway view of vapor separator Check valve should be installed between vapor separator and measure transducer. Some manufacturers mount check valve in the pipeline of vapor separator and transducer, but others install check valve in the inner of vapor separator. Check valve has the function of preventing oil flow backward. The segregated capacity is the major technical parameter of vapor separator. Under low pressure and high temperature a little of gas dissolved in oil is easily separated out. The vapor should be divided out before flowing into measure transducer so as to keep the accuracy of fuel dispenser in the scope stipulated by national standards. Stability is another key parameter of vapor separator. In case that the design fuel dispenser and manufacture sector of pump and vapor separator exist unstable elements, the pressure pulse fluctuation of fuel dispenser’s hydraulic system will increase, even affecting the measur fuel dispenser

ter the market. Money will not be showered on a company the moment it crosses the finish line, but will be paid out a little at a time. In one scenario, the final customers for vaccines would set the pace. For example, the Kenyan health ministry would decide whether to buy a company s vaccine, for $1 per dose, and the company would then receive a “top-up�payment of $14 from the G8. If the pot (including the Kenyan co-payments) contained $3 billion, it would be drained only after 200m fuel dispenser shots had been sold. This, advocates hope, will give a second-generation vaccine time to steal the market from its forerunners. Unfortunately, this set-up creates problems of its own. Corruption is one danger. If every dollar that a health ministry spends on a given vaccine is worth another $14 to the company supplying it, an unscrupulous firm might go to illegal lengths to attract the ministry s custom. A cure or a placebo? What if companies fail to bite at the carrot the G8 dangles before them, or fall short of a vaccine donors are willing to buy? Well then, argues Mr Kremer, donors have lost nothing. If his scheme fails, the public purse has lost hardly a cent. If it succeeds, then every dollar spent is eminently worthwhile. This, needless to say, is a big part of his scheme s appeal to politicians. But Mr Farlow doubts that a G8 promise would be credible unless funds were set aside in advance—money he would rather were used elsewhere. There is much else to spend it on. By one count, more than 25 malaria vaccines are currently in or near clinical trials, pushed by public money and philanthropic generosity. Several vaccines, for example against hepatitis B, have already been invented, but fail to reach all the poor. APCs should not stop governments providing a push wherever it is needed, Mr Kremer insists. But will go fuel dispenser vernments themselves hear him? Critics argue that even if his scheme makes no claim on public funds today, it has still made a big demand on political attention, diverting it from fuel dispenser
