車の車高調節装置。 An automobile height adjustment device that uses hydraulic pressure to adjust the vehicle height includes a hydraulic circuit including an oil reservoir, a hydraulic pump, a check valve, a solenoid valve, a roll restrictor valve, and a hydraulic ram, a vehicle height sensor, a relay, and Consists of an electric circuit including a motor, which rotates the motor to drive the hydraulic pump only when controlling the vehicle height rise, supplying hydraulic oil to the hydraulic ram, and when the hydraulic pump is not operating, hydraulic oil is supplied from the hydraulic ram to the hydraulic pump. This vehicle height adjustment device prevents the backflow of oil by using a check valve, and when controlling the vehicle height, opens a solenoid valve to return hydraulic fluid in a hydraulic ram to an oil reservoir to adjust vehicle height.
