te of Diagram 2-18d after rounding 90 degree. Diagram 2-18d: it is the continuation of the state showed in the diagram 2-18c. Nylon wheel rotates clockwise, and come to the state of Diagram 2-18a after rounding 90 degree. The four pistons discharge out a certain oil under different oil pressure, meanwhile, nylon wheel drive export axis round. Each rotation of export axis means a working circulation. Discharge adjustment The cubage of oil discharged by measurement transducer depends upon the moving distance and cross section of piston according to fuel dispenser the working principal. The moving distance of piston is twice as many as of connecting board. Thus, the oil cubage discharged in a circulation can be showed in the following formula: Vaca = π(d/2)2×2L×4=2πd2L fuel dispenser (2--2) Vaca──Academic discharge in a circulation; d──Diameter of piston; L──The center of connecting board The formula of 2-2 is an ideal discharge volume. But there are many elements affecting discharge, including the centre distance of connecting board, diameter tolerance between piston and bushing, inconsistent clearance between piston and cylinder, different oil viscosity under various temperature, different fluid fluctuation in varied hydraulic system, and measurement transducer variable loan. Thereby, the real discharge is: V real = V ac �△V (2-3) V real ── Real discharge; V ac ──Academic discharge; fuel dispenser V�──Dispersion of academic discharge and real discharge . In order to make the real discharge near to the academic one and ensure keeping the stable and correct relation between the real discharge and export axis, rational design, high machining accuracy and necessary adjustment are needed. The adjusting device mounts two regulative pistons installed in a pair of piston. They are connected with a rod, moving along with pistons until near to furthest point and hit the bolt of adjusting cover. But piston still move, its room substituted by
