The thrust plate includes a pair of thrust plate passageways. Each thrust plate passageway comprises a pair of kidney shaped passages. The first kidney shaped passage is radially aligned with the discharge port of the thrust plate. The second kidney shaped passage is radially aligned with the inlet port of the thrust plate. The first and second kidney shaped passages are connected with a metering groove. Each thrust plate passage is isolated or blocked from the next adjacent thrust plate passage in the low-to-high pressure transition area of the thrust plate.
