Abstract
A hydraulic pump [,] for an electro-hydraulic power steering system is positioned in a fluid reservoir [,] in a pump housing [,]. The pump [,] has an upstream end [,] that receives fluid from a fluid source and a downstream end [,] that is in communication with fluid expelled from the pump [,]. The pump housing [,] has an integral dampening chamber [,] formed therein adjacent the downstream portion [,] of the pump [,]. The dampening chamber [,] helps minimize pressure pulsations before the fluid is passed through an outlet opening [,] in the housing [,] to a steering gear.
