ABSTRACT:
A viscous rotary damping device for a vehicle end gate assembly is provided. The damping device includes a housing member configured to operatively attach to the vehicle body or the end gate assembly. The housing member defines a fluid chamber having viscous fluid therein. The damping device also includes an impeller member having a mast with a first end configured to operatively attach to the other of the vehicle body and the end gate assembly, and a second end having one or more blades projecting outward therefrom. The second end of the mast is rotatably received in the fluid chamber such that the impeller member dissipates kinetic energy generated by the end gate assembly when transitioning between a first, closed position and a second, open position. A cover plate member is preferably coupled to the housing member, and configured to fluidly seal the fluid chamber.
