A controlled force actuating system having a positive Belleville spring and a negative Belleville spring arranged in series between a load member and a reaction member. The positive Belleville spring is initially in a relaxed condition and the negative Belleville spring being initially in a loaded energy storing condition. The negative Belleville spring is an outer annular portion of a diaphragm having a peripheral outer edge and at least on integral finger radiating inwardly from the outer annular portion. The positive Belleville spring is an annulus having inner and outer edges, the inner edge of the annulus lying outside the peripheral outer edge of the diaphragm. A hinge device is provided for pivotally connecting the outer edge of the diaphragm to the inner edge of the annulus. Thus, energy stored in the negative Belleville spring may be applied between the load member and the reaction member, through the positive Belleville spring by an axial control force applied to the at least one finger.
