Abstract
Damping device for moveable furniture parts. A longitudinally displaceable piston on opposing sides forms two variable size working chambers filled with a damping medium via at least one overflow connection. A piston rod led out of the housing is connected to one side of the piston. An adjustment shaft is connected to one side of the piston opposite one of the working chambers, its free end is also led out of the housing. A throttle disc radially protrudes from the circumferential surface of the adjustment shaft. The throttle disc being disposed in a region of an end of a piston passage bore connecting the two working chambers and configuring the overflow connection abutting a front surface of the piston. Recesses in the throttle disc offset from each other circumferentially have different cross-sections. The recesses may be selectively aligned by rotating the adjustment shaft relative to the passage bore.
