Abstract

A hydraulically damping mount includes amount core and an outer tube. In an embodiment, the mount core is supported on the outer tube via a mount spring of an elastomeric material, and the mount spring divides the space formed between the mount core and the outer tube into at least two fluid-filled chambers that are in fluid communication with each other via at least one damping channel and at least one decoupling channel. In an embodiment, at least one torsion-resistant decoupling device is movable back and forth by fluid flows and is arranged in the at least one decoupling channel. In an embodiment, the decoupling device is formed so that during a fluid induced movement of the decoupling device its inflow sides always face the fluid flows.
