Rotary mechanical accumulator, double rotation, with traction springs (Machine-translation by Google Translate, not legally binding)

The rotary mechanical accumulator, of double rotation, with tensile tension is a mechanical assembly composed, simplifically, by a rotary cylinder as a housing on which a ring gear is mounted, with a unique direction of rotation, and an axis in its interior which rotates in the same direction. When it receives mechanical energy through the shaft, thanks to the differential rotation, it submits traction to linear springs accumulating energy in an elastic way. The torque is proportional to the differential angle of rotation.

Cuando recibe energía mecánica a través del eje, gracias al giro diferencial, somete a tracción a unos resortes lineales acumulando energía en forma elástica. El par resulta proporcional al ángulo diferencial de giro.
