Patent ID: 8439335

Claim:
An air-damped engine mount comprising: a bolt; a main rubber into which the bolt is directly fitted and coupled; a hollow main pipe coupled with the main rubber and supporting the main rubber; a cover plate coupled with the main pipe to form a single damping chamber between the cover plate, the main pipe, and the main rubber; a filter module having a flow resistance, the filter module coupled with the cover plate and configured to permit air to communicate through the filter module with the single damping chamber and the outside, wherein the flow resistance against the air passing through the filter module regulates air pressure inside the single damping chamber to reduce vibration in the main rubber; wherein the filter module includes: a filter body connected to the cover plate and including an air channel therein to fluid-communicate with the damping chamber; a filter housing having one open side to receive the filter body therein and the other closed side spaced from the filter body by a predetermined distance to form a first buffering space therebetween; and at least two filter blocks, each having at least one air guide hole, respectively, to control the flow resistance, wherein the at least two filter blocks are coupled to at least one portion of the filter body and/or the filter housing therebetween in a longitudinal direction of the filter body and forms a buffering space between adjacent filter blocks of the at least two filter blocks respectively such that an air passage between the damping chamber and the outside is formed to pass through the air channel, the first buffering space, the air guide holes, and the buffering space; wherein cross-sectional areas of the first buffering space and the buffering space are larger than cross-sectional areas of respective air guide holes; and at least a breathable porous member disposed in the first buffering space, wherein the porous member is coupled to at least a portion of an outer circumference of the filter body and/or an inner circumference of the filter housing.
