Abstract
A hydraulic pump [14] for an electro-hydraulic power steering system is positioned in a fluid reservoir [16] in a pump housing [12]. The pump [14] has an upstream end [40] that receives fluid from a fluid source and a downstream end [42] that is in communication with fluid expelled from the pump [14]. The pump housing [12] has an integral dampening chamber [36] formed therein adjacent the downstream portion [42] of the pump [14]. The dampening chamber [36] helps minimize pressure pulsations before the fluid is passed through an outlet opening [18] in the housing [12] to a steering gear.
