ABSTRACT:
A mobile partition wall includes several wall elements (1, 1') that are each suspended from a track (2) secured to the ceiling of a room. Each wall element is provided with coupling valves (30, 32) which pneumatically interconnect the wall elements to allow the continuous throughflow of compressed air. The compressed air actuates pneumatic stroke devices to press respective seal bars (8, 9) against the ceiling and the floor in order to achieve good noise insulation and stability of the wall elements. The terminal wall element (1') includes a laterally extendable sliding termination panel (70) that is connected to a pneumatic drive device for extending the termination panel from the wall element (1'). In this manner, any vertical gap remaining between the terminal wall element and a wall of the room can be simply close and sealed by the termination panel. Pneumatic valves are arranged to control the pressurization sequence of the pneumatic elements. An extension limit valve is actuated when the termination panel is extended against the room wall, and only then is the compressed air directed to the pneumatic stroke devices for extending the seal bars.
