where air being exhausted out and oil being left. When oil level reaching a certain height, oil is controlled by floater and returned low pressure chamber. The inlet and outlet pressure disappear after fuel dispenser stopping work, check valve is closed controlled by spring. Thereby the upper oil of check valve can’t flow into high pressure chamber. Meanwhile, the taper valve on floater plug the hole at check valv fuel dispenser e seat, check valve also shut down under spring function. Under normal working situation of vapor separator, the oil flowed into separate chamber and returned back low pressure chamber should have an equivalent volume so as to ensure the normal working of vapor separator. If the former oil volume is lower than that of latter, the exhausting pipe would flow out oil. If the oil volume in separate chamber is less than the discharge of check valve, check valve would be opened or closed, so that the accuracy of fuel dispenser will be affected due to pump’s fluctuation. If install check valve, the separate function don’t be affected, reducing flow resistance. If don’t mount check valve , However, returned oil would flow out exhausting pipe after stopping fuel dispenser, and appear cavitation in the down stream of vapor separator and pipeline so that affect next measure accuracy. Therefore, mounting a check valve is necessary to fuel dispenser’s normal operation. Some training books call check valve as outlet valve, but in this manual adapts check valve for facilitating understand. Check valve plays role to release the suddenly high pressure so as to protect hydraulic system. 3. Maintenance and troubleshooting Regularly cleaning filter is principal sector of maintenance during operation. New filling station always full of dirty and waste in tank and pipeline, thus, the normal operation of fuel dispensers are affected. Thus, paying much attention to check and clean of filter. As the manufacturers made this kind of vapor separator are many, the processing method and product understanding to fuel dispenser fuel dispenser

kes it hard to study systematically. In any field of science, small samples lead to spurious results. To find reliable answers to questions about something as infrequent as brain cancer, a whole country s worth of data is needed. Fortunately, at least one country can provide those data Sweden. And in the current issue of Neurology, Dr Altieri describes what he discovered when he analysed the records of the fuel dispenser Swedish Family Cancer Database. This includes everyone born in Sweden since 1931, together with their parents even if born before that date. More than 13,600 Swedes have developed brain tumours in the intervening decades. In small families there was no relationship between an individual s risk of brain cancer and the number of siblings he had. However, children in families with five or more offspring had twice the average chance of developing brain cancer over the course of their lives compared with those who had no brothers and sisters at all. Digging deeper, Dr Altieri found a more startling result. When he looked at those people who had had their cancer as children or young teenagers he found the rate was even higher—and that it was particularly high for those with many younger siblings. Under-15s with three or more younger siblings were 3.7 times more likely than only children to develop a common type of brain cancer called a meningioma, and at significantly higher risk of every other form of the disease that the researchers considered. This finding, added to evidence linking viruses to a broad mixture of different cancers, has led Dr Altieri and his team to propose that bugs caught during childhood from younger siblings, may, indeed, lead to brain tumours. The initial premise of the argument, that the more children there are to bite, spit, climb and cuddle together, the more infections they pick up, has been demonstrated in studies on nursery schools. But the mechanisms by which younger siblings have more influence than elder ones are speculative. Experience suggests that s fuel dispenser fuel dispenser
