Integrated Accumulator Charging Valve/Pump Package - 1

Product Bulletin Integrated Accumulator Charge Valve/Pump Package This integrated package features a MICO® Accumulator Charge Valve and a Haldex W 900 Gear Pump to accomplish the accumulator charge function. The function of a dual accumulator charge valve is to control the pressure in redundant accumulators used in two or more brake circuits. When the pressure in either accumulator decays to the specified low limit a charge cycle is initiated. The flow rate at which the accumulators charge is constant throughout the charging cycle . The charging cycle is complete when the pressure in both accumulators reaches the specified high limit. The brake circuits are protected from pressure spikes at startup by an internal pressure relief valve. Excess flow from the valve may be used for steering, cooling or implement functions. A relief valve is required for these functions. The package offers greater system reliability by reducing system components. It reduces potential leak points as well as plumbing and mounting hardware. Additional benefits include: zz Energy savings from greater than 90% overall pump efficiency across pressure and speed ranges zz Minimal system transients at the start and end of the accumulator charging cycle due to snap like action of the control section zz A switch port for direct mounting of low accumulator pressure warning switch zz Wide range of pump mounting and shaft configurations available
