BELT TENSIONER FOR INTERNAL COMBUSTION ENGINE

摘要

An internal combustion engine having a power generating device, and a transmission link connecting the power generating device to an accessory operated by the power generating device, the transmission link being tensioned by a tension adjusting device which elastically presses a tension pulley against the flexible transmission link by the electric deformability of a deformable parallelepiped solid constituted by a pair of elements formed of composite flexible strips held parallel, and separated, by the permanent fixing of their extremities in a bearing holder block and in an adjustable fastener, the flexible strips possibly supporting a means to modify the flexibility of the elastic tension device which may include a means to damp the vibrations of the flexible link.
