PURPOSE:To make it possible to decrease the vehicle levels at wheels at an equal speed, by disposing shut-off valves and restrictor means in dain passages from actuators to a working fluid supply source to make the adjusting speeds of the vehicle levels at the wheels equal together. CONSTITUTION:Check valves 49 through 52 each incorporated therein with restrictors are disposed in the intermediate sections of pipe lines 20, 21, 24, 25 to be effect to hinder flows of oil from actuators 2 through 5 to solenoid selector valves 43 through 45. Further, upon decreasing of the vehicle level, oils in the actuators 2 through 5 pass through the restrictors 53 through 56 so that the flow rates of oil per unit time, flowing through the pipe lines 20, 21, 24, 25 are maintained substantially constant. With this arrangement the decreasing speed of the vehicle levels at respective wheels may be made equal together, thereby variation of the adjusting speed may be made low. |
