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 fuel dispenser oil of check valve can’t flow into high pressure chamber. Meanwhile, the taper valve on floater plug the hole at check valve seat, check valve also shut down under spring function. Under normal working situation of vapor separator fuel dispenser , 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 sudde fuel dispenser nly 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

order the seizure of evidence abroad. Austrian judges might have been able to use this earlier this year to require British police to confiscate and hand over documents owned by David Irving, the British historian, when he stood trial for Holocaust denial in Vienna, even though Holocaust d fuel dispenser enial is not a crime in Britain. But these steps are not enough for some European governments and the European Commission. They want faster, more efficient legal action against terrorists, drug smugglers and those who commit cri fuel dispenser mes across borders. They argue that, because national governments control criminal-justice and police systems, it is hard to get all 25 (soon to be 27) countries to co-ordinate legal actions. So they want decisions about criminal justice to be taken by majority vote rather than consensus. This would mean that national parliaments and courts would no longer have sole control over their criminal-justice systems. The commission and the European Parliament would gain some competence not only in serious cross-border crimes but, possibly, in criminal law in general. That is roughly what the commission asked national governments to accept in Tampere last week. A majority of governments balked. Ireland objected on principle its justice minister said the idea was an offence against national sovereignty. Germany objected to the tactics, rather than the principle. It said some of the legal proposals were already in the draft constitution that the German government desperately hopes to resurrect—and that it did no fuel dispenser t want to initiate a separate ratification process. Britain havered but eventually came down against the plan. Since it takes a unanimous decision to get rid of unanimity, it seems likely that the whole idea will now fall (although, with the commission still committed, it may be postponed rather than dropped altogether). Criminal justice and policing involve the most fundamental of state powers the ability to deprive citizens of their liberty. People more or less trust nation
