Abstract
The present invention is a viscous damping apparatus for damping mechanical shocks discharged on an object. It comprises a container having an inner chamber which has a flat bottom surface, a damping member having a flat lower surface, and means for suspending the damping member such that its flat lower surface is positioned parallel and very close to the flat bottom surface of the inner chamber of the container. The space between the flat lower surface of the damping member and the flat bottom surface of the inner chamber of the container is very narrow and is filled with a body of viscous fluid. When the damping member vibrates and causes its flat lower surface to move toward the flat bottom surface of the inner chamber of the container, the viscous fluid is compressed, which in turn creates an extremely strong resistance force on the damping member that effectively damps the vibration of the damping member. A preferred embodiment of the present invention viscous damping apparatus is incorporated into a weighing device to damp the vibration of the load cell of the weighing device.
