Abstract
A hydraulically damped elastic mounting, especially for the engines of motor vehicles. To achieve, with a straightforward and economical construction, an effective, purely hydraulic damping of long-stroke, low-frequency vibrations, and a complete absorption of acoustic, i.e. short-stroke, high-frequency vibrations, a working cylinder is filled with a low-viscosity hydraulic fluid, and a damping disk mounted on the connecting rod nearly completely spans the cross-sectional area of the working cylinder. Provided all the way around on the periphery of a damping disk is a profiled shape that seals, in a substantially contact-free manner, the annular gap between the damping disk and the inner wall of the working cylinder. The damping disk divides the working cylinder into two partial chambers that communicate with one another via at least one calibrated transfer passage.
