Abstract

A hydraulically damping rubber mount is provided with a variable channel length. The mount channel length can be adapted to the later intended use with a simple design during the manufacture without changing the design. The hydraulic mount has an elastomeric damping member, at least two chambers to accommodate a fluid damping agent and a channel carrier with a channel connecting the chambers in a flow-conducting manner. The channel has passage openings to the chambers. An incompletely closed ring, one end of which forms a channel deflection, is displaceably guided in the channel in the manner according to the present invention. The channel is divided as a result into two channel parts, which unite between the ends of the ring and through which the damping agent flows in opposite directions.
