Abstract
A torsional vibration damper or a torsionally elastic and vibration damping coupling (,) has radial spring elements (,) inserted between an inner portion (,) and an outer portion (,) for torque transmission and liquid-filled chambers (,) communicating with each other via throttle gaps for damping purposes, where at the one end the spring elements (,) are clamped between adapters (,) in the outer portion (,) and at the other end engage in axial grooves (,) of the inner portion (,), and the chambers (,) are separated from each other by the spring elements (,) on the one hand, and on the other hand by additional radial divisions (,) between adjacent spring elements (,), which divisions spare the throttle gaps (,). To achieve a compact design with improved possibilities for the connection of the inner portion, while reducing the risk of cavitation, the divisions (,) belong to the inner portion (,) and each consist of a foot projection (,) protruding between the axial grooves (,) and an adjoining separating web (,) extending up to the opposing adapter (,) by sparing the terminal throttle gaps (,), where in the foot projections (,) there are provided holes (,) for inserting connecting screws.
