Exploded drawing of double flux solenoid valve From above diagrams, it is known that this kind of solenoid valve consists mainly of valve body, membrane, cone-shaped spring, valve cover, pilot valve, control valve of small flux, reposition valve, winding of pilot valve and small flux valve winding. The working principle of double flux solenoid valve can be leaned from Diagram 2-35. Pilot valve, small flux valve and main valve controlled by membrane are closed after power cut, no oil pass solenoid valve. When both two windings are open, pilot valve and small flux valve switch on, pressured oil pushing down membrane. Part of oil in A chamber flow toward outlet of solenoid valve via pilot valve and small flux valve, main valve is switched on after overcoming spring, at this state, solenoid valve is in large flux. When winding of pilot valve is cut power, pilot valve is closed, membrane go upward so as to close main valve due to oil pressure increase in A chamber. Solenoid valve is in small flux state. If the power of winding of small flux valve is cut off, small flux valve is closed, no flux in solenoid valve. It is learned from above introduction that the large and small flux of solenoid valve are controlled by pilot valve and small flux valve. This is why it called doubl fuel dispenser e flux solenoid valve. As filing motor, pilot valve, small flux valve and main valve are switched on, fuel dispenser work in large flux state. When filling volume nearly reach pres fuel dispenser etting value, winding power of pilot valve is cut off, main valve is closed. However, small flux valve is still working. When filling volume reach preset-value, the winding power of small flux valve is cut off, solenoid valve is closed. Filling operation is end. Troubleshooting In filing operation some troubles maybe correlate to solenoid valve, some maybe to other hydraulic components. Small flux or no delivery in fuel dispenser, for example, it is possible caused by solenoid valve or other components. Therefore, it is need to give concrete analysis and diagno fuel dispenser

for the awkward theory, held by many analysts, that he was more or less forced to quit. Now, after keeping fairly quiet for the past two years, Mr Jiang has again stepped into the spotlight with a pair of new publications. One work is a travelogue documenting the many official overseas trips he took. The other is a three-volume set of his “Selected Works� which went on sale on August 10th, a week before his 80th birthday. Its release puts him in the company of Deng Xiaoping and Mao Zedong as a leader deemed worthy of the honour. State media urged careful study of the opus and carried gushing, if improbable, reports of frenzied queues at bookstores as far afield as Tibet. All the fuss could simply be a way for the new president, Hu Jintao, to heap praise on the old man as he prods him deeper into retirement. However Mr Jiang s re-appearance comes at a time when machinations over the next leadership change are just getting under way. China is due to hold its 17th Communist Party Congress late next year. Mr Hu would not be expected to step down until the following one, in 2012, but the 2007 congress is where the party will begin the work of anointing a successor. If Mr Jiang has any hopes of helping his political allies, and hence of prolonging his own influe fuel dispenser nce, this would be the time to re-assert himself. But if he also wishes to be thought of as China s first modern leader to retire gracefully, he needs to tread carefully. fuel dispenser © 2006 .  About sponsorship Green power in South-East Asia Fuels rush in Aug 24th 2006 | KUALA LUMPUR From The Economist print edition When diesel grows on trees THE fruit of the oil-palm tree, Elaeis guineensis, is wonderfully versatile.
