motor and solenoid valve, w fuel dispenser ith larger power. it also have the type of double-nozzle fuel dispenser mounted with total two sets of system, however, most manufacturers don’t install this type in order to reduce cost. With more than four nozzles, this fuel dispenser is able to be regarded as multi-nozzle type. At recent, most of multi-nozzle fuel dispensers made by domestic manufacturers are rebuilt from double fuel dispenser, which actually mounted two pieces of double fuel dispensers to one frame, in the same way 3 piece to six-nozzle. Therefore, learning the structure of double fuel dispenser is able to know multi-nozzle type. Here main introduce the double-nozzle fuel dispenser. Measuring main board is the core in fuel dispenser’s electric control system, which is reason why some people called this kind as ‘computer fuel dispenser� These operation including starting or stop, calculation, count, data generation and dialogue with machine also are conducted under the control of measuring main board. Display screen, keyboard and fuel dispenser’s switch are the main interface between operator and machine. The staff’s control command to fuel dispenser is mainly conducted through keyboard and nozzle switch, but report information and data are showed in display screen. The function of flow pulse converter, widely called as sensor, is to convert influx into electric pulse so that measuring main board process data. Motor is momentum of rotation of pump; solenoid valve used for presetting filling; power supply board is resource of electric system, which is used for converting alternative current into stable and clean directive current fuel dispenser needed. 2.

ve for those who did not w fuel dispenser ant to join their former comrades in ditching Marxism after the fall of the Berlin Wall. The party now has 41 seats in the lower house and 27 in the Senate. Events since polling day have left no doubt that its leader, Fausto Bertinotti, intends to make this tally count to the full. It was expected at first that the speakership of the Chamber of Deputies would go to the Democrats of the Left, the biggest party in Mr Prodi s alliance, created by those who did decide to give up Marxism in the early 1990s. Massimo D Alema, an experienced parliamentarian who was prime minister from 1998 to 2000, was the obvious choice. But Mr Bertinotti decided that he wanted the job and, in the first serious clash within the centre-left since the election, Mr D Alema, encouraged by Mr Prodi, withdrew his candidacy. This episode illustrates not only the power of Mr Bertinotti, but also the pernicious effects of full proportional representation. It has weakened the big parties that underpin coalition governments, and strengthened smaller ones that are only too ready to bring governments down. Once more, this is disturbingly reminiscent of the world before 1994, when parties with even less popular support than the Refounded Communists exerted huge influence by constant threats of defection. In short, at a time when it ought to be marching bravely into the future, Italy seems to be slipping inexorably back into the past. And that is an even more serious concern than Mr Berlusconi s continuing refusal to accept his election defeat. © 2006 . French trade unions Power without responsibility Apr 27th 2006 | PARIS From The Economist print edition The trade unions have won a victory, but their strength is still declining Get article background “IN REALITY, the problem in our country is not that we have too powerful unions, but that they are too fragmented and too small.�After the capitulation by the French government to student and u fuel dispenser fuel dispenser
