e accuracy. Vapor separator mounted check valve should have the anti-backward flow function. Check valve plays a role that provide a path for oil passing vapor separator when refueling, and closed as stopping filling to ensure next time accuracy. Moreover, it is able to reduce hydraulic impact and strict the high pressure in hydraulic system as nozzle suddenly stopping. Here introduce the structure, working principle and troubleshooting of vapor separator generally employed. Structure Diagram 2-12, 2-13 and 2-14 are shown the structural cutaway view, exploded drawing and dimensional structure. Va fuel dispenser por separator is divided into these components of frame, upper cover, outlet pipe, spring seat and exhausting pipe. By function, it consists of filter device, vapor segregated device and anti-backward flow device, illustrating in Diagram 2-12 and 2-13. 1\2-Bolt 3-Elastic washer 4-Exhaust jointer 5-Upper cover 6-Valve seat 7-Upper cover gasket 8-Valve bracket 9-Small axis 10-Screw 11-Gas outlet valve unit 12-Fuel return float 13-Ball-float 14-Screw 15-Frame 16-Spring washer 17-Seal gasket 18-Filter unit 19-Bolt 20-Filter 21-Stainer net 22-Gasket 23-Filter end 24-Nut 25-Seal gasket 26-Plug 27-Check valve unit 28-Bolt 29-Gasket 30-Check valve washer 31-Check valve 32-Oil pipe 33-Seal gasket 34-Spring seat 35-Bolt 36-Spring 37-Plug 38-Return oil valve seat 39-Return oil valve 40-Spring 41-Seal gasket 42-Guider bar 43-Oil plug 44-One-way valve Diagram 2-13: Vapor separator exploded drawing Filter device: in past filter material adapts industrial felt, which is difficult to clean and has large flow resistance. Then ladies nylon is used, but this kind of material has low filter precision. Domestic manufacturer now widely adapt stainless steel filter, having advantage of anti-rust, even net holes, guaranteed filter precision and low resistance as well. Diagram 2-12 clearly shows the install position of filter. Pump will be effectively protected through installing a high filter precision strainer at the fuel dispenser fuel dispenser

re-elected three times in Rhineland-Palatinate, most recently with an absolute majority in parliament. His homely approach, cautious support for reform and will to get things done could appeal to voters. He would not be the first earthy, well-rounded leader from the state to prove Germany s highbrow press wrong when Helmut Kohl became CDU leader in 1973, most pundits declared that he had only a limited future. © 2006 .  About sponsorship Romania and Bulgaria A dim green light May 18th 2006 From The Economist print edition fuel dispenser A mumbled invitation to join the European Union in 2007 ROMANIANS have a joke about driving to Greece. Tank up before you get to the Bulgarian border, lock the doors and windows, put your foot down and don t stop until you reach the other frontier. Bulgarians say the same about driving north to Hungary. Other Europeans, it seems, would rather drive elsewhere. Romania and Bulgaria are due to join the European Union on January 1st 2007. This week, the European Commission could have advised that they get the formal go-ahead. Instead it fudged. Preparations for admission should proceed, it says—but with a further review in the autumn of progress on reforms. If either country scores spectacularly badly then, its accession could be put off for a year. In practice, any such delay now looks out of the question for Romania, and highly unlikely for Bulgaria. Romania was originally seen as the more problematic of the two. It is big, with 20m people, very poor, and was until recently ruled by a venal and incompetent clique of ex-communists and their hangers-on. But over the past two years Romania has made startling progress, particularly in the trickiest areas of judicial administration and home affairs. The commission says it is now worried only about minor issues, such as improving slaughterhouse hygiene. Such quibbles spare a few blushes next door, where the criticism is sharper.
