Beschreibung
Zusammenfassung:	1. Active, hydraulically damping engine bearing, in particular for motor vehicles, having two chambers (1, 2) with rubber elastic peripheral walls (5, 9) and having a rigid intermediate plate (3), between the two chambers (1, 2) and two parallel overflow openings (4, 10), in the intermediate plate (3), of which one overflow opening (10) has parallel plate-like electrodes (11, 12, 13) for applying an electrical field and is spanned on its upper and lower side by thinwalled rubber diaphragms (16, 17) which are connected in a fluid-tight manner to the intermediate plate (3), with only the space (18) enclosed by the rubber diaphragms (16, 17) being filled with an electroviscous fluid and the other chamber areas (1, 2), which are connected by a second channel-like overflow opening (4) enclosing the first overflow opening (10), containing a low viscosity damping fluid, characterised in that the electrodes take the form of sieve-like plates (11, 12, 13) which are disposed in the overflow opening (10) at right angles to the flow direction.
