Summary:Rotary damper (4) comprising: a housing (5) having at least one fluid chamber (6) filled with a viscous fluid; a wing shaft (7) with a wing (8) projecting in a radial direction of the wing shaft toward a curved cylindrical and/or conic side wall (10) of the fluid chamber (6) and comprising: a first side (11), a second side (12), a top side (13), a bottom side (27) and an upper side (28); a fluid passage (15) between the first wing (8) and a wall (25, 26, 10) of the fluid chamber (6) wherein at least one groove (16.1, 16.3, 16.5, 16.7, 16.9, 16.11, 16.12) is provided, the groove being provided in a side (13, 27, 28, 31) of the wing (8) and/or in a wall (10, 25, 26, 30) of the fluid chamber (6). The at least one groove is entirely filled with the viscous fluid, the viscous fluid in the at least one groove being in fluid communication with the viscous fluid of the fluid passage allowing the viscous fluid of the fluid passage to flow through the at least one groove.
