Abstract

Abstract A pretensionable and hydraulically damped mounting element with an outer mounting sleeve, an inner part, which is held by an elastomeric body in the interior of the outer mounting sleeve, the elastomeric body above and below the inner part being formed with chambers serving as a mechanical spring and being filled with hydraulic fluid and connected to one another via a channel, and end caps located at respective end faces of the mounting element and being formed of elastic, deformable elastomeric material, the elastomeric body extending from the inner part substantially radially outwardly towards opposite sides of the outer mounting sleeve, the elastomeric body and at least one of the end caps defining the channel therebetween, the channel having a variable cross section includes means defining axially extending additional chambers arranged at both sides of the inner part of the elastomer body, the additional chambers communicating with the channel.
