ABSTRACT:
A controlled force actuating system to apply and release an actuating force between a load member and a reaction member and includes an energy storing positive spring and an energy storing negative Belleville spring arranged in series between the load member and the reaction member to exert a range of actuating force on the load member varying between minimum and maximum values. The positive spring has a length and a positive force/deflection ratio. The negative Belleville spring has a length and a negative force/deflection ratio related to the positive force/deflection ratio so that the positive spring and the negative Belleville spring may reach a state of equilibrium substantially throughout the range of actuating force. The positive spring and the negative Belleville spring present a total length including both the axial lengths of the respective springs. A mechanism is provided for varying the total length of the springs for controlling the actuating force while maintaining the springs substantially in a state of equilibrium throughout the actuating force range between the minimum and maximum values.
