An integrated accumulator charge valve and gear pump package has resulted from a collaboration between Mico and Haldex Hydraulics. It reduces plumbing and mounting hardware to create a less complex, durable, and efficient design for vehicles using a full power hydraulic brake system. The Haldex gear pump operates across a range of pressures and speeds. Benefits include reduced potential for leak paths, improved incorporation into an overall design, and additional efficiency since excess flow is provided from the charge valve to operate steering, cooling, or implement functions. Optional single or dual accumulator ports offer four charging rates between 0.5 and 5.0 gal/min (1.9 and 19 L/min), and the unit displaces up to 1.4 in3 (35.6 mm3) with system pressures up to 3000 psi (207 bar).
