<p>A damped hinge comprising: a first leaf (32) for securing the hinge to a fixed support; a second leaf (35) for securing a moveable closure to the hinge; a barrel (33) secured to the first leaf (32), the barrel (33) including an axial bore (34); a piston (30) mounted for axial movement within the bore (34), the piston (30) including a cam surface (45); an axially extending member (39) constrained to rotate with the second leaf (35), the member (39) including a cam follower (42) arranged to engage the cam surface (45); the cam surface extending axially so that the piston (30) moves axially within the bore as the second leaf is rotated in relation to the first leaf; a hydraulic fluid contained within the bore (34); at least one of the piston (30) and member (39) including a passageway through which the hydraulic fluid may flow as the piston moves within the bore; wherein the passageway includes an adjustable valve (48, 49) to restrict the flow of fluid to damp opening or closing of the hinge.</p> |
