PURPOSE:To suppress a feeling of disorder following a sudden car height variation by feeding an operation fluid from a control valve to an operation fluid chamber through a one-way passage device in the stage when the operation fluid feeding pressure is less than a specific value, at the starting of operation of a car height regulation device for automobile. CONSTITUTION:When a car height regulation is started to operate, and in the stage when the operation fluid feeding pressure, that is, the pressure of the operation fluid feeding passages to operation fluid chambers 2FR-2RL, does not reach a specific value, the operation fluid is fed to the operation fluid chambers 2FR-2RL from control valves 40-46 for regulating the car heights, not through cutoff valves 197FR-197RL, but through a one-way passage which is composed of passages 197FR-197RL and check valves 199FR-199RL. By such a constitution, the pressures at the front side and at the rear side of the cutoff valves are made practically equal a large amount of operation fluid flow when the cutoff valves are opened can be suppressed, and a feeling of disorder following a sudden car height variation can be prevented. |
