Abstract
An active two-chamber engine mount with hydraulic damping includes rubber-elastic peripheral walls, a rigid intermediate plate disposed between the walls defining chambers, an electro-viscous fluid filling the chambers and flowing in a given fluid flow direction through at least one overflow opening formed in the rigid intermediate plate. At least two mutually parallel metallic mesh plates are successively disposed across the given fluid flow direction in the vicinity of the at least one overflow opening, and a control device for alternatingly applying an electric field to the mesh plates as electrodes for controlling the viscosity of the fluid.
