Abstract

An elastic engine mount includes upper and lower bearing plates. A hollow-cylindrical spring block has top and bottom ends being clamped between the bearing plates and defining an inner space. A bolt protrudes into the inner space from the upper bearing plate. The spring block is formed of an elastomer and has conduits formed therein with at least one open end and a varying cross section. The conduits are disposed in a plurality of planes and are mutually parallel within each respective plane. A transverse elastic wall for additional damping is centrally fixed to the bolt for dividing the inner space into two liquid-filled chambers. The elastic wall has through openings formed therein and has an outer periphery clamped between the lower bearing plate and the bottom end of the spring block.
