Abstract: The invention provides a mechanism for attenuating torque pulsations between an engine (2) and a rotor (1) of a rotorcraft. Torsion means (5) are interposed between the driving and driven shafts and comprise a torsion shaft (6) axially engaged with the drive shaft (3) and the driven shaft (4) an inlet shaft (9) and an outlet shaft (10) respectively engaged with the drive and driven shafts (3, 4) a lever system (7) that extends radially relative to the torsion shaft (6) and that has the inlet and outlet shafts (9, 10) hinged thereto via points (11, 12) that are spaced apart; and a mass (8) carried by said lever arm (7) at its free end (13) radially farthest away from the axis along which the torsion shaft (6) extends.

Abstract: A torsional vibration damper has at least one inertia mass, which is connected in a rotation-proof manner to a drive and acts upon an absorption mass. The absorption mass is rotatable relative to the inertia mass and is connected thereto via connecting elements. Associated with the absorption mass is a balancing weight, which is connected via a movement-transmitting transmission to the absorption mass, on the one hand, and to the inertia mass, on the other hand.
