Abstract
In an arrangement according to this disclosure, a spring element (3, 7) is arranged between a mounting core member (2) and a support (6) and is connected to a damper mass (9, 12). The damper mass has a container (10) which is filled with pressure liquid and/or gas and closed by a diaphragm (13). The spring rate of the diaphragm can be varied as desired, particularly in dependence on the speed of rotation of the machine or engine. For varying the spring rate of the diaphragm, a pressure plate (15) is associated with the diaphragm, and is displaceable relative to the diaphragm by way of an adjusting arrangement (16, 17) dependent on the speed of rotation of the machine or engine, and the relative configurations of the pressure plate and the facing diaphragm are such that this displacement reduces or increases the free area of the diaphragm, and thus varies its spring rate.
