A hydraulic damper 10 is provided; the hydraulic damper 10 being suitable for damping a hinged closure, such as a door. The hydraulic damper 10 comprises; an orifice 18 for restricting flow of a working fluid 16; and an orifice forming member 36 which forms the orifice 18. The orifice forming member 36 is movable in a first direction towards a first internal surface 40 of the damper, and in a second direction towards a second internal surface 42 of the damper, thereby to decrease the size of the orifice 18, depending on the applied force. The damping coefficient of the hydraulic damper 10 is thereby increased as an increasing force is applied to the hydraulic damper 10 under compression and under tension. A hinged closure incorporating the hydraulic damper 10, and a method of damping such a hinged closure using the hydraulic damper 10 are also disclosed.
