ABSTRACT:
A dual-chamber support bed or motor vehicle engine mount with hydraulic cushioning includes a resilient housing part and a support base for use in defining a working chamber and compensating chamber filled with liquid, the housing walls are annular rubber diaphragms with a buckling characteristic that is adjustable to adapt to the operating load. The chambers are connected to one another through a nozzle channel. Means for controlling the buckling characteristics (buckling rigidity) are provided in a wall of the working chamber and in a preferred embodiment include an additional buckling spring that is clamped into the fixed base housing and is adjustable in its buckling behavior from the exterior by a spindle.
