pistons in same axis line are connected through connecting rod. A column spring is set between each piston and connecting rod, piston and connecting rod move along axis direction. An O ring is installed between connecting rod and piston to prevent leakage. A small axis is inserted into the holes of upper and lower connecting rods. A circle nylon wheel is set between the upper groove of upper connecting rod and two pistons. The small axis of nylon wheel is inserted into the hole of crankshaft. Piston 16 and piston 26 mounted adjusting piston. Four pistons installed at the end of frame respectively. The journey of adjusting piston is adjusted by the adjusting bolt installed at the end cover. 1-Outlet elbow 2-End cover 3-Piston 4-Frame 5-Connecting sheet 6-Low connecting bar 7-Upper co fuel dispenser nnecting rod 8-Cylinder bushing 9-Adjusting bolt 10-Cap nut 11-Regulalting piston 12-Driving elbow 13-Brass bushing 14-O-ring 15-Rotation output axis 16-Nylon wheel Diagram 2-17: Structural chart of metal piston measurement transducer Working principle Pistons shuttle under the oil pressure after clean and no-air oil flow into measurement transducer via vapor separator.

Meanwhile, the oil calculated flow out of outlet through measurement transducer. The rotation is corresponding to the oil volume. The oil volume passed fuel dispenser over measurement tr fuel dispenser ansducer is a stable constant. A complete working circulation of four pistons under oil pressure is corresponded to a unit circle of export axis. Diagram 2-18 shows the four working status during a whole working circulation. Diagram 2-18 is a simplified working principle drawing of measurement transducer. In order to facilitate explanation label the cylinders and pistons as 1, 2, 3 and 4, the position of most far away the center of piston called the furthest point, nearest position called the nearest point

duce their use of options. Indeed, Microsoft went so far as to abandon them entirely in 2003. According to David Zion of CSFB, an investment bank, the fair value of options awarded by S&P 500 firms fell from $104 billion in 2000 to $30 billion last year. There is reason to hope, then, that option backdating is one form of executive-compensation abuse that has had its day. © 2006 .  About sponsorship Executive pay Up or down? Jul 20th 2006 | NEW YORK From The Economist print edition A debate over how much American bosses are paid Get article background IT IS a rare trade association that boasts that its members are not paid as well as is widely believed. But that is exactly w fuel dispenser hat the Business Roundtable, representing 160 chief executives of big firms, did this month. “Reports that large numbers of chief executives make hundreds of millions of dollars every year are simply untrue,�said John Castellani, the roundtable s president. “Executive compensation has closely followed the growth that companies have experienced in the last ten years.� The compensation of the median chief executive of the 350 big firms in the Business Roundtable s sample fell to $6.83m in 2005 from $7.04m in 2004, and was lower than in 2001 (see chart). This finding has generated huge controversy. The roundtable has been accused of ignoring some valuable components of pay, such as pension benefits fuel dispenser and dividend paym fuel dispenser ents on restricted shares held by bosses, and of understating the value of options and other equity grants made to them. Add these in, and pay is still soaring, say critics. Who is right? Steven Kaplan, an economist at the University of Chicago, calculates that measured ex ante (valuing options using the Black-Scholes formula, rather than by what they later turn out to be worth when they are exercised) and in real terms, for firms in the S&P 500 index, average chief-executive compensation pea
