Abstract
A hydroelastic mount for interposition between two units to be insulated from each other, for example a motor-drive unit and the structure of a motor vehicle, the mount comprising an elastic mass (1) disposed between two carrying armatures (17, 18), two chambers (6, 12) which are filled with liquid, interconnected by a communication passageway (8) and at least partly defined by elastic walls (1, 13). The two chambers (6, 12) have an annular shape and the mount defines a central empty space (21) for the passage of a connecting rod (20) between one of the carrying armatures (18) and the unit to which it is connected. This arrangement simplifies the assembly when the unit to be insulated is placed thereunder.
