发明名称 Rhythmic motion driver
摘要 A rhythmic motion driver having a case containing flywheels and a guide along which the flywheels move linearly while rotating. A spring is within the case that compresses and expands in response to oscillatory motion of a bar that extends through an opening in the case. The spring compression and expansion is slowed but not dampened by the movement of the flywheels.
