Abstract
A tubular shaft comprises a torque-transmitting tubular structure compris at least one torque-transmitting shell, which has elastic properties oriented along at least one helical line. To permit the tubular shaft to be used as an effective vibration damper, the shell surrounds a pumping chamber, which is adapted to contain a damping liquid and communicates through at least one constricted passage with a reservoir for damping liquid.
