Abstract: The invention relates a torsional vibration damper, comprising the following features: a primary part with two lateral discs (1, 2) which are connected to each other for conjoint rotation; a secondary part with a central disc (3) which is arranged between the lateral discs; a primary part and secondary part are rotationally connected to each other via springs (5); damping chambers which are filled with a damping medium and each have at least one throttle opening; guide elements (7.1) are provided for supporting and guiding the springs. The invention is characterized by the following features: each spring is assigned two guide elements which are both arranged at mutual axial distance and form the supporting surfaces against a movement of the spring in the radial and in the axial direction.

Abstract: The invention relates to an elastic coupling in disc construction, in particular for damping torsional vibrations of an internal combustion engine, having the following features: a first coupling half, which comprises two side discs, which are connected in a rotationally-fixed manner on the outer circumference; a second coupling half, which is formed by at least one middle disc assigned to a hub, which is arranged between the side discs and enveloped thereby; the two coupling halves are pivotable to a limited extent to one another against the force of at least one elastic coupling element; the side discs delimit a liquid-tight inner space, which receives the middle disc, at least one damping chamber, which is variable in volume during the mutual pivoting of the coupling halves and is filled with a damping medium, is arranged in the radial outer area of the inner space; a floating damping ring, which is pivotable to a limited extent in relation to each of the two coupling halves, is introduced into the inne

Abstract: The invention relates to a device for damping oscillations, especially an oscillation damper
