Damped hinge
A damping arrangement (preferably a sealed unit) having a damping piston 16 mounted within a bore of a housing 13 and engaging a spindle (3, fig.1); the piston acting perpendicular to the spindle. A baffle 22 with an aperture 23 within the bore. The piston 44, bore and first side of the baffle forming a first fluid chamber; a variable volume chamber forming a second fluid chamber on the second side of the aperture; the second fluid chamber may be coaxial with the bore or may be parallel and laterally offset (fig.5). A valve arrangement controlling flow of hydraulic fluid through aperture 23. The valve arrangement may comprise a one-way valve 24 with an axial aperture 37 which communicates with the tapered stem 32 of an inline coaxial needle valve. The valve allows free movement of fluid from the second chamber to the first chamber and restricted flow via needle valve in the opposite direction. May be used in a hinge or a door closer.
