ABSTRACT:
A hydraulic pressure control apparatus for stabilizers controls hydraulic fluid in a hydraulic communication path hydraulically connecting cylinders each operatively connected to each stabilizer of a vehicle. The apparatus includes a spool valve provided in the hydraulic communication path. The spool valve includes a housing, a spool accommodated in the housing, first and second spool chambers defined by the spool and the housing, and a biasing member for biasing the spool. The apparatus further includes first, second, and third hydraulic communication passages, hydraulically connecting an accumulator hydraulically connected to the second spool chamber and the hydraulic communication path, hydraulically connecting the first spool chamber and the hydraulic communication path, and hydraulically connecting the spool chamber and the accumulator respectively, first, second, and third solenoid valves provided in the first, second, and third hydraulic communication passages respectively, and a control device for controlling the first, second and third valves.
