A common hydraulic power supply for a motor vehicle power-steering system and power brake system. The hydraulic power supply supplies hydraulic fluid from a power-steering pump continuously through a flow control valve to a power-steering system. The power brake system is supplied with hydraulic fluid from an accumulator as required. The accumulator is charged with hydraulic fluid by the power-steering pump. Accumulator charging occurs when the pressure in the accumulator falls below a predetermined value, and is accomplished by the diversion of a portion of the flow from the power steering pump to the power brake system. The diverted fluid passes through a pressure sensing valve, the flow control valve, a check valve, and into the accumulator.
