Abstract
Abstract A first component in a drive is rotatable in one and in an opposite direction. A second component, such as a shaft, is rotatable also, and is connected with energy storing means which stores energy when the second component rotates. A transmission is provided which connects the first and second components to rotate the second when the first rotates. The transmission has a first branch provided with a first device which transmits motion from the first component to the second component only when the first component rotates in one direction but will not transmit such motion when this first component rotates in the opposite direction, and there is further provided in the transmission a second branch having a second device which transmits motion to the second component only when the first component rotates in the opposite direction but will not transmit motion when the first component rotates in the first direction.
