    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 win fuel dispenser ding 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 double flux solenoid valve. As filing motor, pilot valve, small flux valve fuel dispenser and main valve are switched on, fuel dispenser work in large flux state. When filling volume nearly reach presetting 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 f fuel dispenser uel dispenser, for example, it is possible caused by solenoid valve or other components. Therefore, it is need to give concrete analysis and diagno

Per Calculator up to 8  different Prod_Nb could be defined.  The access to this data is defined by the PR_ID address (product identifier). This address key  is used for internal links between databases (product logical nozzle meters). These links  depend on the way the dispenser is built and are dispenser model dependent.  The PR_ID = 40H is used to ask for all products.  Any attempt to operate on a DB_Ad which has not been implemented should be rejected with  a MS_ACK set to NAK 2 (applica fuel dispenser tion non existent on the recipient node).

    ility is that he did not intend to do any such thing, and that Mr Olmert s robust response to Hizbullah s cross-border raid took Mr Nasrallah by surprise. Another theory is that he did intend to provoke a war, but not for his own movement s sake. He may have been acting in the interests of Iran and Syria. That is what America and Israel say they believe. George Bush said this week that Syria wanted to overthrow the pro-Western, anti-Syrian coalition government in Lebanon. Syria s president, Bashar Assad, he implied, could stop the violence with a click of his fingers. Mr Olmert, meanwhile, accused Iran of instructing Mr Nasrallah to start a war to distract world attention from Iran s apparent effort to flout the Nuclear Non-Proliferation Treaty and build a nuclear bomb. It is almost certainly not so simple. It is clear that Hizbullah depends heavily on both those countries for its moral and logistical support; Iran, not Syria, is its chief mentor. It is also true that Iran and Syria, and Hamas and Hizbull fuel dispenser ah, have lately drawn closer in an anti-American front across the region. But Hizbullah s relationship with the ruling mullahs is not a simple client-patron one. Hizbullah s leadership has a lot of autonomy in making decisions. Iran may oversee strategy, but Hizbullah works out tactics. In any event, Iran sounds well please fuel dispenser d with the current rumpus. The more Israel and America blame it for goading on Hamas and Hizbullah, and the more insistently they accuse Iran s munitions experts of giving Hizbullah advice, the more proudly Iran struts the regional stage. Yet in Tehran it is not clear who is calling the shots in Lebanon, let alone Gaza. It is unlikely that Hamas and its Sunni Arab leaders are—as John Bolton, the American ambassador to the UN, claims—a proxy for the Shia Persians who dominate Iran. And few people in Iran think that relation fuel dispenser s between Mr Nasrallah and Iran s supreme leader, Ayatollah Ali Khamenei, can be reduced to those of client and boss. For sure, Iran is wid
