ping a little oil flow out of corrugated pipe, put a container under it. The method is suggested to be applicable to other maintenance of hydraulic components. Article VI Solenoid valve In this Article a switch, controlled by electric components, is installed at inlet or outlet of measurement transducer, which is used for ensure the accuracy of presetting filling volume of fuel dispenser. Nozzle cannot be closed after finishing presetting volume due to the inertia of pump and pressured oil, which results in that real volume exceed presetting volume so as to affect fuel dispenser’s accuracy. In order to prevent this phenomenon occurring, most of manufacturers of fuel dispenser adopt to mount a solenoid valve at inlet or outlet of measurement transducer, switching off valve prior to presetting volume getting reach through regulating appropriate ahead volume. The method is one of the most efficient measures that used for ensuring f fuel dispenser uel dispenser’s accuracy and preventing overrun resulted from the inertia of pump and pressure oil. There are two kinds of solenoid vale --- membrane type and piston type. The former, simple structure and high anti—pollution, is closed through membrane. However, its performance is depended upon the technology about membrane and weather. The latter valve controlled through piston has wide applicable range of temperature, weak to anti-jammed pollution. Do fuel dispenser uble flux solenoid valve is controlled by the position movement of cam that is driven by mot fuel dispenser or, and large or small flux is realized through the open or closed of main or vice valve. It has merits of wide applicable temperature range, high pollution-resistant. At present, most manufacturers adopt double flux membrane solenoid valve in fuel dispenser. Double flux solenoid valve Structure and working principle Membrane solenoid valve is widely adopted recently, which also called double flux solenoid valve, shown in Diagram 2-35 and 2-36. Diagram 2-35: Working principle of double flux solenoid valve Diagram 2-36:
