The transfer of impact force from a mechanically, pneumatically, or hydraulically driven knock or impact-beating device, which is mounted externally of a container that receives dust-laden, hot, and/or contaminated gases, onto bearing or cooling surfaces which are installed within the container, and which are to be intermittently cleaned. The impact force is indirectly transferred via the container wall to a striker which is pressed against an inner wall of the container by a resilient power accumulator. Preferably, the striker has a mass equal to that of the knocking element of the knock or impact-beating device. Pursuant to one embodiment of a device for effecting transfer of the impact force, the striker disposed within the container is guided within a connector-like inlet of the container body. The cover part associated with the inlet has a central bore and, on that side thereof facing the interior of the container, has a projection which coaxially surrounds the bore. A diaphragm wall rests against the projection, and is peripherally connected via weld projections with the inlet or with the cover part. The striker is provided with an equalization channel which connects the two pressure chambers. Via a spring which engages shoulders of the inlet, the striker is pressed against the diaphragm wall.
