Abstract
A damping device (100), in particular to dampen impacts of mobile parts in pieces of furniture, comprises: a casing (1) containing a viscous fluid; a piston (3) slidably mounted inside the casing (1) and defining inside the casing (1) two regions with variable volume, which are in fluid communication at at least one duct defined in the piston (3) and at an hollow space defined between the outer surface of the piston (3) and the inner surface of the casing (1). The damping device (100) is characterised in that the piston (3) comprises a floating shutter (5) suitable for closing the at least one duct defined in the piston (3) during the working stroke of the piston (3) and for opening the at least one duct defined in the piston (3) during the reset stroke of the piston (3). The damping device (100) allows a substantial reduction in the reset force of the piston (3) to be obtained maintaining a particularly simple structure and low manufacturing costs.
