Abstract

A switchable hydraulically damping mount, having a supporting mount and a supported mount which are resiliently braced against one another by a support spring made of an elastomeric material. The mount includes at least two working chambers filled with fluid and arranged one behind another in the direction of vibrations introduced during operation. The working chambers are delimited on the sides facing one another by a common partition and are connected in a fluid-carrying manner to one another by at least one damping channel arranged in the partition. The partition has a central recess that is a component of a passthrough opening, such that the passthrough opening can be opened by an actuator, which can be acted on by a pressure medium, of a positioning device. The passthrough opening has a meander-shaped cross section extending in the radial direction.
