spenser because of stable operation, high anti-interference, high accuracy, long service life and wide scope of temperature adaptability, etc. Although clearance exist between piston and bushing, the leakage is very less, even no leakage. If the whole hydraulic system, including measurement transducer, work stably, with small pressure fluctuation, the leakage between piston and bushing too small to calculate when light loan. At present, the accuracy and reliability of metal-piston measurement transducer made by some domestic manufacturers are able to compare with that of famous export brand. The leakage c fuel dispenser hange is still little under the various temperatures because of low expansibility of metal piston. Therefore, it is able to keep high accuracy even in wide scope of temperature change, which is outstanding merit. Structure The exploded drawing and structural chart of metal piston measurement transducer are showed in Diagram 2-16 and 2-17. It mainly consists of frame, piston, connecting rod, connecting board, nylon wheel, driving elbow, adjusting device, end cover, etc. 1-Cap nut 2-Gasket 3\3A-Adjusting bolt 4-Nut 5\6-Hexgon screw 7-Spring gasket 8-11-12- End cover 9-Cover gasket 10-Body 13-Bolt 14-Spring washer 15-Flat washer 16-Piston set 17-Spring 18-Flat washer 19-Nylon unit 20-Upper connecting rod 21-Jointing sheet 22-Lower connecting rod 23-24-Piston unit 25~33-Piston adjusting unit 34-Gasket 35-Bolt 36-Screw 37-43-Pin 38-Jointer 39-Rotation output axis 40-O-ring 41-Brass bushing 42-Driving elbow 44-Seal gasket Diagram 2-16: Exploded drawing of one kind of metal piston measurement transducer Inlet is located down of frame, which is connected with the outlet of vapor separator through pipeline. The middle of frame is oblong chamber connecting to four cylinders. The side of cylinder connects to nearby cy fuel dispenser linder. The each upper part of cylinder has an elliptical hole, which is connected to the circle groove of upper frame. Four pistons are installed in cylinders, respectively. The two fuel dispenser

whenever Poland is mentioned. And the prime minister, Jaroslaw Kaczynski, always talks of Polish national interests as if they naturally run counter to those of the EU. Poland s European partners may be irritated by this, but the voters seem only mildly bothered. Local elections last month provided a test. Overall, Law and Justice did respectably, especially in rural areas. But it lost the crucial battle for Warsaw. The mayorship, once held by Lech Kaczynskzi, the prime minister s twin brother who is now Poland s president, has a budget of over � billion ($2.6 billion) and thousands of staff. La fuel dispenser w and Justice s candidate was a popular former prime minister, Kazimierz Marcinkiewicz, but he was beaten by a former central-bank governor, Hanna Gronkiewicz-Waltz, who declared after her victory that more people were now realising “that Law and Justice Twins twisting in the wind governs ineffectively� Law and Justice still has several popular politicians, notably the justice minister, Zbigniew Ziobro. Aged only 36, the media-savvy Mr Ziobro has cut both crime and the cost of seeking legal advice. His latest coup was to persuade America to arrest, pending extradition, Edward Mazur, a Polish-American businessman. Mr Mazur, who denies any wrong-doing, is accused of involvement in organised crime and the 1998 murder of a top policeman—a crime that successive governments have been mystifyingly reluctant to investigate. The government has not brought the revolution in public administration that it once promised. But it is at least using European money to modernise Poland s agriculture and transport system. The minister in charge, Grazyna Gesicka, has simplified application procedures. The amount being successfully sought from Brussels ha fuel dispenser s risen fivefold. Poland is due to receive some �0 billion from the European Union between 2007 and 2013. Even Polish business, usually a harsh critic of the government s st fuel dispenser
