ABSTRACT:
A hydraulic pressure supply apparatus includes a variable displacement pump which is controlled to change its discharge flow rate and pressure in accordance with a condition of a load side. The pump is communicated with the load side through a conduit to which an accumulator is communicated through a proportional pressure reducing valve controlled so that its regulating pressure is higher than the pressure required in the load side and is lower than a target discharge pressure of the pump. Furthermore, when the pressure in the conduit is lower than the regulating pressure of the valve, the valve is opened and regulates the pressure in the conduit by allowing higher pressure flow from the accumulator.
