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 fuel dispenser 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 rotation is corresponding to the oil volume. The oil volume passed over measurement transducer 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
