ds of gear pumps. The following introduce cycloidal ge fuel dispenser ar 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 overflow valve move sideward, 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 val fuel dispenser ve 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. fuel dispenser However, as close down nozzle, pressured oil overcome spring bounce under high pressure in hydraulic s
