ABSTRACT:
A drive system includes a rotary drive unit for rotating a shaft and a linear drive unit for moving the shaft in a linear direction. To improve efficiency and shelf life, an energy storage is mechanically connected to the shaft for biasing the shaft to seek a linear movement in opposition to the linear direction. The energy storage absorbs the kinetic energy of the shaft and releases it again subsequently.
