Abstract
A torsional damper suitable for use in a friction clutch plate for an automotive vehicle comprises a hub and a disk mounted so as to rotate relative to one another against the action of springs. An intermediate member responsive to centrifugal force moves reversibly between a standby position and an operative position, in order to modify the operating characteristics of the damper. The intermediate member modifies these characteristics in its standby position, and can occupy either of two operative positions, in one of which it has no effect on and in the other of which it also modifies the aforementioned operating characteristics.
