A power steering pump having a plate disposed between a first surface and an intake chamber, wherein an intake flow channel defined by the first surface is in fluid communication with the intake chamber through an opening extending through the plate, the plate opening having opposed terminal ends. The intake flow channel defined by the first surface is configured to direct fluid flow through the plate opening into the intake chamber at a location through the plate opening that is intermediate and spaced from the two terminal ends of the plate opening. Also, a power steering pump having a plate disposed between a first surface and a pair of intake chambers, wherein a pair of intake flow channels defined by the first surface are in fluid communication with the intake chambers through a corresponding pair of openings extending through the plate. A pressure balancing fluid communication channel extends between the pair of intake flow channels to provide fluid communication between areas of the two intake flow channels where each intake flow channel is in communication with an opening extending through the plate, the pressure balancing fluid channel tending to equalize the fluid pressure in the two intake flow channels at the areas where they communicate with the plate openings.
