A device for storing and delivering elastic energy (1), which comprises:
- elastic means (3) adapted to store and deliver elastic energy,
- a ring (5) adapted to be connected kinematically to a machine to which the elastic energy stored in the elastic means (3) is to be delivered, or from which energy to be stored in the form of the elastic energy in the elastic means (3) is to be drawn;
- a first motion transmission shaft (7) which is connected kinematically to the elastic means (3), wherein the rotation of the first shaft (7) in a first direction of rotation (A) loads the elastic means (3),
- a mechanical exchange device (9, 19) configured to render the first shaft (7) integral with the ring (5) in the first direction of rotation (A) and to render the first shaft (7) free with respect to the ring (5) in a second direction of rotation (O), which is opposite with respect to the first direction of rotation (A), allowing the free rotation of the ring (5) in the second direction of rotation (O),
- a second motion transmission shaft (11), the mechanical exchange device (9, 19) being configured to render the second shaft (11) integral with the ring (5) in the second direction of rotation (O),
- an assembly (13) for transferring the motion from the first shaft (7) to the second shaft (11),
- a freewheel mechanism (15) configured to transmit the motion from the first shaft (7) to the transfer assembly (13) only in the second direction of rotation (O) of the first shaft (7),
- a mechanism for locking the elastic means (3), which can be activated in order to lock the elastic means (3) in their loaded or partially loaded configuration, wherein the deactivation of the locking mechanism releases the elastic energy stored in the elastic means (3), producing the rotation of the first shaft (7) in the second direction of rotation (O). |
