inlet of pump. Vapor segregated device: key component of vapor separator. It includes the following components ---High pressure chamber composed of frame and upper fuel dispenser 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 factories evolve the spheroid buoy with exhausting valve and exhausting seat as a ball valve, illustrating in diagram 2-15. Now some manufacturers 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 fuel dispenser Diagram 2-15 Structural drawing of single direction valve This kind of vapor segregated device has large pressure chamber in which oil flow slowly 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 cham fuel dispenser ber 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

frica s magic that transformed modern art Feb 9th 2006 | JOHANNESBURG From The Economist print edition An exhibition in South Africa reveals the depth of A fuel dispenser frican influence on Picasso PABLO PICASSO never went to Africa. But more than three decades after his death, his art is travelling to the continent that so deeply affected his work. “Picasso and Africa� the most extensive exhibition of the artist s work ever assembled in the region, was due to open at the Standard Bank Gallery in Johannesburg on February 10th, and will travel to the Iziko South African National Gallery in Cape Town in April. The show, which highlights Africa s influence on Picasso s work, brings more than 80 of his paintings, drawings and sculptures together with a selection of African masks and statues sim fuel dispenser ilar to those that he had around him as he worked. Picasso said that the “virus�of African art stayed with him throughout his life. He caught it in June 1907, when stumbling upon the African and Oceanic collection at the Ethnographic Museum of the Trocadéro in Paris. The fateful encounter was a revelation “The masks were not simply sculptures like any other. Not at all. They were magical objects.�That day, he later said, he Out of Africa understood what painting really meant. “It is not an aesthetic process; it s a form of magic that interposes itself between us and the hostile universe, a means of seizing power by imposing a form on our terrors as well as on our desires.� He had been working on “Les Demoiselles d Avignon� which became one of his most famous paintings. The visit to the museum gave him the answers he had been looking for. This portrait of five prostitutes, which he described as fuel dispenser his first “exorcism painting� was his first work to bear signs of African influence, with two of the women s faces shown as African masks. Many other signs were to follow. The exhibition shows how Picasso absor
