摘要：
A gear housing for a power steering system defines a valve bore, a pressure port, a plurality of orifices opening into the valve bore and a plurality of passageways interconnecting the plurality of orifices and the pressure port. The plurality of orifices direct a power steering fluid into the valve bore at multiple locations within the valve bore, thereby providing a balanced flow of the power steering fluid into the valve bore. The plurality of orifices is disposed about a bore axis, with each of the orifices angularly spaced about the bore axis relative to all of the other orifices.
