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 fuel 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. Double flux solenoid valve is controlled by the position movement of cam that is driven by motor, and large or small flux is r fuel dispenser ealized through the open or closed of main or vice valve. It has merits of wide applicable temperature range, high pollution-r fuel dispenser esistant. At present, most manufacturers adopt double flux membrane solenoid valve in fuel dispenser. Double flux solenoid valve Structure and working principle Membrane fuel dispenser solenoid valve is widely adopted recently, which also called double flux solenoid valve, shown in Diagram 2-35 and 2-36.

. And he created a highly compartmentalised organisation—to avoid infiltration by communists, but also to conceal the embarrassing fact that many of his recruits were ex-Nazis. These murky origins may help to explain why, in its early days, the BND seemed rather accident-prone. In 1961, for instance, it turned out that its head of counter-intelligence, a veteran of the Nazi special forces, was actually an agent of the KGB. More recently the fall of the Berlin Wall presented the agency with a fresh set of problems. As well as losing its main enemy, it had to face some embarrassing revelations about continuing communist infiltration of its ranks, while at the same time adapting to a new set of threats, from Balkan wars to loose nukes. A decade of budget cuts followed, along with infighting at the top, lack of oversight and, as a result, further scandals. Only in the late 1990s did the German government see that it needed better spooks. Much has already changed since. A culture of pointless secrecy has been dropped among the signs of a new openness are a series of BND souvenirs (including underwear stamped “confidential matter�, occasional background briefings for the press and an annual public symposium on a weighty subject. More important, of the institution s 6,000 employees a third are recent recruits, most of them hired on the open market rather than secretly commandeered through an old-boys network. The agency s leadership and analysis units have already been moved to Berlin. fuel dispenser At its 50th anniversary last May the BND proclaimed its rebirth as a modern intelligence agency—a protector of “peace and qui fuel dispenser et� in the words of a cheesy promotional video.
