Title:
VEHICLE LEVEL ADJUSTING DEVICE
Document Type and Number:
Japanese Patent JPS62122810
Kind Code:
A
Abstract:
PURPOSE:To prevent a light beam from a vehicle on the opposite lane from dazzling the concerned vehicle in the night time, by disposing a pressure differential valve in the branch section of oil passages connecting a pump to front and rear jacks so that the rear jacks are operated in advance of the front jacks when the level of the vehicle is raised while the front jacks are operated in advance of the rear jacks when the level of the vehicle is lowered. CONSTITUTION:During the raising of the level of a vehicle, a pump 2 is normally rotated by a motor 1, hydraulic oil in a tank 3 is fed into a pressure differential valve 8 through oil passage 4, 6. Therefore, the pressure differential valve 8 is actuated so that it is communicated with a branch passage 11 to operate rear jacks 12 for raising the level of the rear section of the vehicle. When a predetermined amount of oil is fed into the rear jacks 12 so that the pressure in the branch passage 11 becomes high, a relief valve in the pressure differential valve 8 is opened to allow hydraulic oil to flow into jacks 10, 10 through the branch passage 9 to raise the level of the front section of the vehicle. During the lowering of the level of the vehicle body, the motor 1 is reversed to actuate the spool valve 15 so that hydraulic oil is fed through an oil passage 16 to operate the pressure differential valve 8, and therefore, the hydraulic oil is discharged in advance from the front jacks 10. Thus, it is possible to reduce the affection of a light beam from a vehicle on the opposite lane.
