Input torque, at a comparatively low energy level and preferably delivered constantly, is converted to comparatively high energy output torque pulses by storing the applied torque in a leaf spring which, in its unstressed state, is elastically deformed. Energy is accumulated in the spring by twisting it about its longitudinal axis through rotating a first end thereof. Stored energy is released by periodically allowing the second end of the spring to rotate. |
