Abstract

Hydraulic damping single-chamber mounting for motor vehicles with two rigid end walls axially disposed opposite one another, and at least two chambers containing damping fluid disposed axially behind one another. In a first of the two chambers, the damping fluid can be both compressed and decompressed. A rigid partition separates the two chambers. The partition is fixed and rigidly clamped on its outside circumference. The chambers are in communication with one another by means of a circular channel running around a central axis of the rigid partition. The rigid partition is located radially inside an elastic, axially-movable membrane. The membrane is fixed and rigidly clamped on its outside circumference. The rigid partition has at least one overpressure valve which operates for each direction of positive pressure between the chambers to prevent noises during cavitation in the decompression phase and pressure peaks in the compression phase within the first chamber.
