Abstract
A vibration absorbing mounting, e.g. a motor car engine mounting, has a rubber spring member mounted between end members and hydraulically damped. The interior of the mounting comprises two liquid-filled chambers communicating with one another through a restricted passageway and which are separated by an intermediate diaphragm and bounded at their other sides, respectively, by the rubber spring member and a second diaphragm. The second diaphragm is provided with a central support and the intermediate diaphragm may have an unyielding central portion, to enable excessive movement of the end members towards one another to be resisted.
