Abstract
A controllable hydraulic bearing, especially for motor vehicles, with a working chamber and an equalizing chamber arranged annularly around the working chamber. The chambers are filled with an electrorheological fluid and are connected to one another via an annular gap-like overflow channel. The overflow channel has two mutually opposite electrodes for generating a high-voltage field in the overflow channel. The overflow channel ( ) extends helically in its longitudinal extension around the said working chamber ( ) between the working chamber ( ) and the equalizing chamber. The wall of the overflow chamber ( ) comprises an electrically insulating carrier layer provided on both sides with conductive cover layers forming electrodes.
