(EN) Reversible unidirectional transmission
Abrégé
(EN)

A transmission is provided which has unidirectional output rotation in response to multidirectional input rotation. A reversing member is provided for changing the direction of rotation of the output member. A first mechansim rotates the output member in a first direction in response to a first direction of rotation of the input member, and this first mechanism does not drive the output member in response to a second direction of rotation of the input member. A second mechanism rotates said output member in the first direction in response to the second direction of rotation of the input member, and this mechanism does not drive the output member in response to the first direction of rotation of the input member. The axis of rotation of the input member and the axis of rotation of the output member are coaxial.
