Abstract
At least one confined chamber is formed by one and the other mounting fixtures and by a wall of rubber elastomer hermetically connecting the two fixtures, and a pump chamber made operative to effect a pumping action in response to the vibrations of the one mounting fixture is formed separately of the aforementioned confined chamber so that the atmosphere is pumped into the confined chamber from that pump chamber. In the damper support thus constructed, since the air is pumped into the inside when in the vibrations of low frequency, the damping factor can be made large. Even in the vibrations of high frequency, the dynamic spring constant can be made small.
