ABSTRACT:
A hydraulic mount has an upper support member and a lower support member. An upper elastomeric spring and a lower elastomeric spring are disposed between the upper support member and the lower support member to define an upper fluid chamber and a lower fluid chamber. A channel extends between the upper and lower chambers. During compression and extension of the hydraulic mount, fluid transfers between the upper and lower chamber to provide a damping force for the hydraulic mount.
