A damping device ( 100 ), in particular for damping impacts of mobile parts in pieces of furniture, comprises: a casing ( 1 ) wherein is defined an inner chamber containing a viscous fluid and substantially closed at one end through a cap ( 2 ); a piston ( 3 ) slidably mounted in the inner chamber; a stem ( 4 ) having a first end ( 4 a) associated with the piston ( 3 ) and a second end ( 4 b) projecting from the inner chamber. The damping device ( 100 ) is characterised in that the cap ( 2 ) comprises at least one floating gasket ( 28 ) slidably mounted in a cavity ( 24 ) defined in the cap ( 2 ), said floating gasket ( 28 ) defining a region with variable volume in the cavity ( 24 ) suitable for receiving the viscous fluid displaced into the inner chamber by the stem ( 4 ) during the movements of the piston ( 3 ). The cavity ( 24 ) defined in the cap ( 2 ) and the floating gasket ( 28 ) slidably mounted in it define a system for compensating the variation in volume available in the inner chamber to receive the viscous fluid, due to the insertion/removal of the stem ( 4 ).
