REGULATOR MECHANISM WITH A TURBINE SPEED-CHANGING DEVICE

The turbine shaft speed maintained by the regulator can be changed by adjusting the tension of spring 1, linked through lever 3 to sleeve 2 of the centrifugal governor. At a constant turbine load, if the tension of spring 1 is increased, sleeve 2 moves downward. At this, lever 3 turns about point A, shifting valve spool 5 upward. This directs hydraulic fluid so that piston 4 and valve member 6 mov…
