Claims

[Scope of utility model registration request]

(1) Hydraulic vehicle height adjustment device that incorporates a hydraulic cylinder siding device into each wheel suspension device on the front, rear, left, and right sides, and adjusts the vehicle height by controlling the increase or decrease of oil in each hydraulic cylinder device by operating an oil pump. In the oil supply path from the oil pump to each hydraulic cylinder device, there is a cylindrical sub-tank, a piston fitted therein, and a piston that detects the operating position of the piston and operates the oil pump. A vehicle height sensor consisting of a switch to stop the vehicle is provided, and when the oil pump is operated in one direction, the piston moves within the sub-tank to supply oil in the sub-tank to each hydraulic cylinder device to raise the vehicle height. A control device for a hydraulic vehicle height adjustment device for an automobile, characterized in that the oil in each hydraulic cylinder device is drained into the sub-tank by operation in the other direction to lower the vehicle height.

(2) The vehicle height sensor is incorporated in an oil pump device that includes an oil tank, an oil pump, a control valve, etc. as an integrated unit, as set forth in claim 1 of the utility model registration claim. Control device for hydraulic vehicle height adjustment device for automobiles.
