Patent abstract
A new apparatus for reducing sway of a trailer towed by a towing vehicle has a draw bar for linking a trailer to a vehicle, a ball for hitching the trailer to the draw bar, and a pin for hitching the draw bar to the vehicle. The apparatus also has a body that is associated with the ball in such a way that horizontal angular movement of the draw arm relative to the draw bar causes a substantially equivalent horizontal angular movement of the body relative to the draw bar. A hydraulic dampener linked to the body dampens horizontal angular movement of the body and, thereby, dampens horizontal angular movement of the trailer.
