ABSTRACT:
A four chamber hydraulic steering damper where a two sided rotary vane moves working fluid from one side of each vane to the adjacent side of the same vane when rotated in synchronism with the steering mechanism. The working fluid is directed through narrow passageways that may be metered and/or valved. Each chamber may have a unique or similar pressure relief area creating varying dampening through the steering rotation. The damper may be affixed to the steering shaft directly or by linkage to the steering shaft or another moving component of the steering assembly.
