ds of gear pumps. The following introduce cycloidal gear pump: Diagram 2-8: Two kinds of internal gear pumps Gear pump structure Diagram 2-9 is an exploded drawing for inner cycloidal gear pump. Inner cycloidal gear pump mainly composed of frame, gear-group, overflow valve, strainer, pump cover subassembly, etc. pump chamber is cylinder-shape in which strainer is installed at inlet of oil. Overflow valve and pump is in parallel connection. Concentric installation is between pump chamber and exterior gear-group, between inner gear and principal axis. But inner gear and outer gear is assembled centrifugally. Principal axis drives gear-group rotate. Gear pump has two chambers --- pressure oil chamber that discharge oil and suction chamber that suck oil—which are not connectable. When gear pump operating gear-group rotate anticlockwise at view of pump cover direction. Delivery pressure depends upon the adjustment of overflow valve, laden degree and inner penetration. In the process of nozzle open, small oil resistance, overflow valve is in low status of openness. However, as nozzle turn down or large oil resistance and pressure, the spring of overfl fuel dispenser ow valve move si fuel dispenser deward, increasing openness so that more oil flow into negative chamber. The outlet pressure of pump keeps under 0.3Mpa. Working principle of overflow valve The outlet of overflow valve is the interface in where pressured oil chamber pass into suction chamber. The overflow valve play role as a protection to restrict the highest pressure in hydraulic system and to adjust delivery volume of fuel dispenser. Its structure is illustrated in Diagram 2-9. Motor driving pump starting work, the pressured oil from pressure area flow into vapor-separator and overflow valve outlet via pump outlet. Given switch nozzle, part of oil flow out of pipe of vapor separator, another part of oil flow into suction chamber via overflow valve with small openness. However, as close down nozzle, pressured oil overcome spring bounce un fuel dispenser der high pressure in hydraulic s

it is necessary to wait　　 until the nozzle is returned before allowing the state to change away from the Idle　　 state. This implies that any attempt to release the pump while the illegal nozzle is　　 removed must be rejected with a Data_ACK of 6 (Command not accepted). After　　 the nozzle is returned a new transaction is able to start.　　 EVENT DESCRIPTION　　 VALID-NOZZLE-UP The customer selects any logical nozzle and the FP moves to the CALLING state.　　 INVALID-NOZZLE- Action : The FP state change is send as an unsolicited data array　　 UP FP_Status_Message .　　 RELEASE_FP The pre-authorization can only be accepted if at least one transaction buffer is　　 available. The number of transaction buffers is configured by the contents of the　　 data element Nb_Tran_Buffer_Not_Paid.　　 If there are is no unit price available any attempt to release a fuel pump should be　　 fuel dispenser reje fuel dispenser cted with a Data ACK of 6.　　 A FP could be assigned to a CD by the contents of the data element　　 Assign_Contr_Id (Data_Id 22 in the Fuelling Point Database). If the FP is assigned　　 to a CD the FP can only be released by the CD that assigned it.　　 Any fuelling limit must be transmitted to the FP before the Release_FP command is　　 transmitted. The pre-authorization could be done without any limit with a volume　　 limit (preset mode) or an amount limit (prepay mode).　　 The FP receives a pre-authorization and the FP moves to the AUTHORISED state.　　 PCD Comment:　　 As most proprietary FP s only allow o fuel dispenser

it would be best for all concerned (including future members) to pause while everything settles down. Indeed, this is the emerging conventional wisdom. Yet it is wrong in almost every particular. Europeans are not opposed to enlargement in general (though they may be to the specific case of Turkey). A slim majority is in favour. A new poll by the European Commission s public-opinion arm has more people saying that enlargement is a good thing for the EU (55%) than that the EU is a good thing for their own countries (49%). If national politicians were serious about reflecting public opinion, they should be calling for a pause in all activities of Brussels, rather than in further expansion of the club. It is not clear that enlargement fatigue is really about public opinion at all. What is clear, in contrast, is that the 2004 enlargement to the east has produced net benefits for Europe, increasing trade, investment and income. In principle, there could still be winners and losers. Opposition to enlargement might be concentrated among the losers, just as support is strongest in the three member states—Britain, Ireland and Sweden—that have opene fuel dispenser d up their labo fuel dispenser ur markets to new members. But in fact enlargement s impact on jobs in countries most vehemently opposed to expansion (eg, France) has been minimal, partly because the French have insulated themselves from it and partly because French unemployment is a self-inflicted wound, not the result of competition from central Europe. In short, although some people blame Polish plumbers for taking their jobs, there is no evidence that this is actually happening. Has enlargement gone too fast? It took 15 years from the fall of the Berlin Wall for the first ex- communist countries to join the EU—three years more than the time between Franco s death and Spain s accession. Has it made the EU s institutions unworkable? So far, the EU has functioned broadly as well—and as badly—with 25 members as it did with 15. Nor is fuel dispenser all the EU s money being
