PURPOSE: An emergency system for the power steering system of a vehicle is provided to lower a mold cost for producing components and blocks by facilitating to supply or discharge oil with respect to each solenoid valve. CONSTITUTION: An emergency system for the power steering system of a vehicle comprises a first oil tank, a first oil pump, a steering gear box, a power cylinder, a second oil tank, a sub motor, a second oil pump, a controller, and first, second, and third solenoid valves(57,58,59). The first, second, and third solenoid valves are integrated into a single valve block. The valve block is independently formed with an inner passage. The valve block comprises a block body(200) for accepting the lower body(120) of a solenoid valve; first, second, and third inlet holes; and first, second, third, and forth outlet holes. The valve block is returned to the second oil tank by being discharged through the forth outlet hole(236) from the third solenoid valve in an emergency. |
