ABSTRACT:
A hydraulically damping two-chamber engine mount includes chambers being bordered with rubber-elastic material and an intermediate plate with an overflow conduit and a central diaphragm. For force-free motion of the diaphragm in the vertical direction, the diaphragm is constructed as a rolling diaphragm, in such a way that a conduit of reduced width at the top and bottom is provided between the diaphragm of rigid material and the intermediate plate surrounding it annularly. In the conduit, on the opposed conduit walls, rolling elements with a circular cross section are inserted for rolling support of the diaphragm.
