A Section and B Section are the neared vane, which rotate together with rotor clockwise. The turning Vane A increases the cubage of low pressure transitional area, oil being sucked into pump. Fuel between vane A and Vane B is br fuel dispenser ought to high pressure transitional area as the vane go around clockwise. In high pressure transitional area cubage become smaller because of vane rotation, as result, oil is impelled out under the vane pressure. When rotor turns continually oil in tank is sucked into pump and then discharged out ceaselessly to form a stable flowage. Pump flowage formula is showed in Diagram 2-1.

ace Russia, which is their main gas supplier, but even that does not require heavy intervention from Brussels. Indeed, none of today s big concerns about energy would seem to justify a new policy of the kind proposed by the commission, which includes encouraging new links (“interconnections�? between national electricity grids, setting up stockpiles of gas and perhaps creating a European energy regulator. What would justify some of this is the presence in the energy business of two publi fuel dispenser c goods benefits to people as a whole that are not being realised either by national governments or by markets. For a decade, the commission has concentrated on liberalising national energy markets. It has been reasonably successful in getting countries to privatise state-owned utilities; most gas and fuel dispenser electricity is now supplied by private firms. It has been less successful in reducing the monopoly power of those firms. A recent report by the competition directorate complained that monopoly suppliers still carve up markets, stifle competition and refuse new entrants access to gas and electricity grids. The commission, rightly, threatens to deploy EU competition laws. But it would surely do that whether the policy questions were national or Europe-wide. Energy liberalisation is not the same as an EU energy policy; nor has it created an EU energy system. Europe has a string of national grids, with few bilateral links. Spain s market is almost entirely self-contained. So is the Baltic one. Less than 10% of European gas is sold across borders. A genuine European market—ie, one electricity grid and a single spaghetti-plate of gas pipelines—would enable the entire EU-wide network to be run more efficiently. This is the first of those public goods. Every power system needs spare capacity to deal with surges, supply disruptions and so on. The larger the system, the smaller that spare capacity. In the early 20th century, every town in Britain and France had its own power station. When countries then cr fuel dispenser
