mospheric pressure. If v1is certain, the less A2 / A1 the much v2, which are got from Formulae 2-7 and 2-8. Automatic shut is depended upon fluid pressure. When inlet vent is flooded by oil, membrane is moved upward because of negative pressure on upper membrane. In that state, main valve is closed under the function of switch handle. In order to ensure auto-shut performance, the section of vice valve passage is generally smaller, pressure loss being larger. Therefore, the flow of auto-shut nozzle is smaller than that of general nozzle in filling process. Because the vent of auto-shut is communicated with atmosphere in f fuel dispenser illing operation, splashing oil may lead to switch off of nozzle, especially in smaller tank. Customer should select appropriate auto-shut nozzle to refuel. Usage and Maintenance During operation light put up and down auto-shut nozzle, regularly add lubricating oil on top level of main valve, ensuring that flexible manipulation. Prompt fuel dispenser ly replace invalid components. Pay much attention to passage of auto-shut nozzle, preventing waste jam passages and auto-shut function lost.
