inlet of pump. Vapor segregated device: key component of vapor separator. It includes the following components ---High pressure chamber composed of frame and upper cover; vapor segregated chamber that used to be called general pressure chamber, due to vary along with pump pressure, returned oil floater being installed here; spheriform buoy with exhausting valve, exhausting valve seat, returned oil floater, returned oil valve and exhausting pipe. Some facto fuel dispenser ries evolve the spheroid buoy with exhausting valve and exhausting seat as a ball valve, illustrating in diagram 2-15. Now some manufactu fuel dispenser rers replace ball valve with other structure that promotes the separator capacity. Diagram 2-14 Dimensional structure drawing of vapor separator 1-Valve cover 2-Vavle body 3-Steel ball 4-Upper cover Diagram 2-15 Structural drawing of single direction valve This kind of vapor segregated device has large pressure chamber in which oil flow slow fuel dispenser ly so that vapor has time upward. Therefore, this kind of vapor separator is better than that of small pressure chamber in terms of separate capacity. Anti-backward flow device: it mainly composes of spring seat, spring, check valve unit and outlet pipeline. Check valve gasket is made of oil-resistance rubber board, which is very important for realizing anti backward flow function. Working principle After starting a new fuel dispenser larger air in pipeline is impelled out through check valve and exhausting valve. As there is no foam found in oil indicator fuel dispenser would be refueled. Fuel contained foam flows out of check valve through the bottom of high pressure chamber. The floater in high pressure is upward, levels of exhausting valve and its seat at parallel height, floated air and rest of oil flow into vapor separator chamber from the groove of exhausting valve. If that is ball valve, the steel ball has covered the hole on valve cover, these air and flow only flow from the groove of ball valve. The mixture of oil and air flow into vapor separator chamber in
