A hydraulic-damping two-chamber engine mount includes a working chamber facing toward an engine, a compensating chamber, and an intermediate plate separating the chambers from each other and having an overflow conduit extending helically therein through which the chambers communicate hydraulically with one another. The intermediate plate has two sides and an outer periphery merging into a cylindrical ring extending beyond both of the sides. The ring has an outer surface with two axially superposed conduits formed therein having ends and extending over at least a portion of the outer periphery of the intermediate plate. The intermediate plate has a longitudinal axis and has a conduit portion formed therein extending obliquely relative to the longitudinal axis through which one end of each of the superposed conduits communicate with each other. An outer conduit wall in the form of a cylindrical mount housing has an inner wall surface covering the superposed conduits. The cylindrical ring has corresponding radially inwardly oriented openings formed therein through which the other end of the superposed conduits communicate with the working chamber and with the compensating chamber.

Hydraulic-damping two-chamber engine mount

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.
