Abstract
A hydraulic circuit and a hydraulic control system for preventing fluid leakage and power loss resulting from jamming of contaminants. A first circuit section has an accumulator for storing hydraulic pressure, and a control valve for controlling a passage for delivering fluid from the accumulator to an actuator. Fluid discharged from an oil pump is delivered continuously to a second circuit section. A first filter is disposed on a passage for delivering the fluid from the oil pump to the accumulator for the purpose of removing contaminants finer than those in the fluid to be delivered to the second circuit section from the fluid to be delivered to the accumulator.
