Patent Primary Examiner
A decoupler pulley is provided for automotive belt-driven accessory drives, which utilizes a single torsion coil spring that provides torsional resiliency and overrunning functionality. As the torsion spring expands it increasingly pinches a bushing disposed between a radially expansible hub and pulley to thereby provide proportional damping.
