Abstract
A torsional detuner for dampening vibrations developed in an internal combustion engine having a crankshaft, a flywheel connected to the crankshaft and a transmission assembly coupled to the flywheel. The detuner includes a planar body mounted to the flywheel and having a central hub, a peripheral rim and a plurality of elastically deformable members connecting the hub to the rim. The deformable members extend outward from the hub to the rim in an outwardly radial spiral. Advantageously, vibrations developed in the engine are dampened by the relative rotation between the hub and rim.
