Abstract
In a liquid pressure control system including a spool-type control valve mounted between a liquid pressure source and an actuator in such a manner that an output liquid pressure from the liquid pressure source is controlled in accordance with a thrust exhibited by a linear solenoid, a manually operated valve is disposed in a valve housing of the control valve to have an operational axis parallel to an axis of the linear solenoid. The manually operated valve is capable of blocking the communication between the actuator and the control valve and bringing the liquid pressure source into communication with the actuator to bypass the control valve. Thus, the supply of a liquid pressure to the actuator can be secured in any abnormality of the control valve, while enabling a reduction in size of the system in an axial direction of the control valve.
