| description | A vehicular hydraulic system having a hydraulic pump, an optional flow-splitting valve, a first hydraulic application, a pressure reducing valve and a second hydraulic application arranged in series along a primary flow path. When the pressure in the primary flow path between the pump and first application is elevated to a first threshold value, the flow-splitting valve, if present, splits the fluid discharged by the pump into a first fluid flow communicated to the primary flow path upstream of the first application and a second fluid flow communicated to the primary flow path between the first application and the pressure-reducing valve. The pressure reducing valve limits the maximum pressure of the fluid discharged therefrom to a second threshold value wherein the first threshold value is greater than the second threshold value. The first and second hydraulic applications may take the form of a brake booster and a steering gear, respectively. |
