Abstract: PURPOSE: To obtain desired speed regulating rate of a turbine through full stroke by so constructing bellows as to make contact with an elastic member arranged to impart reverse force to the extending direction to the bellows.  
     CONSTITUTION: Main an sub bellows 20 and 21 are comined to allow the sub bellows 21 to be operated as an elastic member. When a turbine is accelerated from rated speed state (in which the main bellows 20 are extended and the sub bellows 21 are slightly compressed) to raise the pressure in a bellows chamber 8, the main beffows 20 are compressed and the sub bellows 21 are extended by a stroke Sb to cause only the main bellows 20 to operate against a lever 11. That is, the speed regulating rate is determined only by the spring constant of the bellows 20 while the stroke is within Sb to Sg, and determined by effective spring constant synthesized by both the bellows 20 and 21 while the stroke is between 0 and Sb. Accordingly, the stroke can arbitrarily shange the speed regulating rate while the stroke is between 0 and Sb by selecting the characteristics of the sub bellows 21.
