Abstract
A hydraulic sleeve having at least two liquid-filled working chambers. These chambers are in flow communication with one another through a damping channel. The hydraulic sleeve comprises an inner supporting body surrounded by an outer supporting body. A radial clearance is maintained between the inner and outer supporting bodies. An elastic spring element of elastomeric material is arranged in the gap formed by the radial clearance, and at least one separately produced insertion part is arranged in at least one of the working chambers. The elastic spring element has an essentially triangular cross-section and bounds the first working chamber. The insertion part is arranged within the triangularly bounded, first working chamber, has an essentially .OMEGA.-shaped cross-section, and divides the first working chamber into three sectional chambers. The sectional chambers are in flow communication with one another through two throttle orifices that are bounded by the elastic spring element and the insertion part.
