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 t fuel dispenser aper 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, 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 d fuel dispenser own 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. Thu fuel dispenser s, 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

But Kennedy would not be deterred. “Ladies and gentlemen�? he began, “I m only going to talk to you just for a minute or so this evening. Because I have some very sad news.�? The speech was one of the great pieces of political rhetoric an oration that registered the enormity of the event while also beginning the work of healing. There were riots in 76 American cities over the next few days. Indianap fuel dispenser olis remained quiet. Kennedy s words marked the end of an era when politicians could dare to be natural. Today political professionals—consultants, pollsters and admen—test out every phrase. The result is a veritable Hobson s choice the droning inanities of a John Kerry versus the scripted platitudes of a George Bush. “Politics Lost”—the loss of all spontaneity in politics today—is everything that readers have come to expect from the author of “Primary Colours�? Based on a lifetime of careful observation, it is full of colourful vignettes and wonderful phrases (Michael Dukakis hailing from the “National Public Radio w fuel dispenser ing of the Democratic Party�?, and it is suffused with powerful affection for the promise of American politics and exasperation at its reality.
