ABSTRACT:
A hydraulic damper for an apparatus for measuring weight or force. The apparatus includes a base frame and an elastic load cell attached to the base frame, the elastic load cell having a movable part which vibrates relative to the base frame. The damper comprises pair of spaced support members fixed ot each other and to one of the base frame and movable part, a partition member fixed to the other of the base frame and movable part and positioned between the support members, a pair of flexible wall members extending between the partition member and the support members to form a pair of sealed chambers on opposite sides of the partition member, a narrow passage interconnecting the chambers, and liquid contained in the chambers whereby movement of the movable part of the load cell effects relative movement between the partition member and the support members to force liquid to flow between the chambers via the narrow passage thereby to damp the movement of the movable part of the load cell.
