    ping a little oil flow out of corrugated pipe, put a container under it. The method is suggested to be applicable to other maintenance of hydraulic components. Article VI Solenoid valve In this Article a switch, controlled by electric components, is installed at inlet or outlet of measurement transducer, which is used for ensure th fuel dispenser e accuracy of presetting filling volume of fuel dispenser. Nozzle cannot be closed after finishing presetting volume due to the inertia of pump and pressured oil, which results in that real volume exceed presetting volume so as to affect fuel dispenser’s accuracy. In order to prevent this phenomenon occurring, most of manufacturers of fuel dispenser adopt to mount a solenoid valve at inlet or outlet of measurement transducer, switching off valve prior to presetting volume getting reach through regulating appropriate ahead volume. The method is one of the most efficient measures that used for ensuring fuel dispenser’s accuracy and preventing overrun resulted from the inertia of pump and pressure oil. There are two kinds of solenoid vale --- membrane type and piston type. The former, simple structure and high anti—pollution, is closed through membrane. However, its performance is depended upon the technology about membrane and weather. The latter valve controlled through piston has wide applicable range of temperature, weak to anti-jammed pollution. Double flux solenoid valve is controlled by the position movement of cam that is driven by motor, and large or small flux is realized through the open or closed of main or vice valve. It has merits of wide applicable temperature range, high pollution-resistant. At present, most manufacturers adopt double flux membrane solenoid valve in fuel dispenser. Double flux solenoid valve Structure and working principle Membrane solenoid valve is widely adopted recently, which also called double flux solenoid valve, shown in Diagram 2-35 and 2-36.

    fattens the revenues of Ecuador s government, and Mr Correa showed Mr Chávez s penchant for spending it. He became a popular hero by dismantling a fund meant primarily for paying debt in order to boost social spending and was soon forced out (under pressure from Ecuador s foreign creditors, his defenders allege). His constituent-asse fuel dispenser mbly plan echoes the one Mr Chávez used to consolidate his power and Bolivia s project to “refound�the country. “Everyone thinks he s Chávez and he s not,�says Juana Ordóñez of Multiplica, an economic consultancy. Certainly, he is more worldly than the Venezuelan strongman or his radical Bolivian counterpart, Evo Morales. Sometimes, he is pragmatic. He opposes Ecuador s use of the dollar as its currency, which has brought low inflation, but does not plan to stop it. The constituent assembly, he suggests, will strengthen democratic institutions rather than undermining them. He wants to “depoliticise the courts� conduct a “deep reform�of the government bureaucracy and have congressmen elected by district rather than by province, making them more accountable to their electorates. Yet doubts persist. “If developments push his government against the wall he may take anti-democratic measures,�worries Pablo Andrade of Universidad Andina Simón Bolívar. That may well happen. Congress will resist Mr Correa s call to drown itself in his constitutional deluge. The army, still the final arbiter in Ecuadorean affairs, is likely to take its side. Mr Correa intends to appeal to the people, but they will follow only so far. Unlike Bolivia s political eruptions, which originate from below, Ecuador s are sustained in part by the middle class. Conditions are wretched. Despite years of oil- fuelled growth, more than half the population lives below the poverty line; a similar proportion is underemployed or jobless. Yet Ecuador s unrest is provoked less by deprivation than by anger at a grasping elite. That has fed Mr Correa s support but may also put fuel dispenser fuel dispenser
