Abstract

PURPOSE: To realize the minaturization and high precision for the indicating mechanism with a simple constitution of the power balance type in which the servo system is formed with use of the nozzle, the flapper mechanism and the bellows each.
CONSTITUTION: With application of input signal voltage Pin, input bellows 2 has the rotary motion counterclockwise with flexure 24 used as the intermediate vertical axis. Thus the gap is decreased between nozzle 5 and balanced beam 3, and the back pressure of the nozzle increases. Accordingly, the inner pressure increases for displacement output bellows 6 into which the nozzle back pressure is introduced, and bellows 6 has the clockwise rotary motion with flexure 64 used as the intermediate vertical axis. And pointer 8 indicates the pressure of that time. On the other hand, the right end of feedback spring 7 is shifted toward the right by the rotary motion of bellows 6 to apply the feedback force to beam 3. As a result, beam 3 stands still at the position where the balance is secured between the force caused by bellows 2 and the feedback force.
