Automobile altitude valve assembly

The utility model discloses an auto height valve assembly, including a valve body with horizontal cavity and vertical cavity, valve handle and rotating shaft. The valve handle is in the vertical cavity of the valve body, while the rotating shaft is in the horizontal cavity of the valve body. A small valve body is also included and connected to lower part of the horizontal cavity and there is a second air inlet and a third air outlet on the small valve body. The small valve body is also equipped with a valve assembly, and an air intake valve is mounted between lower part of the valve assembly and small valve body. Cam mechanism is fixed on the rotating shaft, and top of the valve assembly is close to the cam mechanism. In the utility model, when the vehicle body is lifted by force, a swing stem swings downwards to drive the rotation of the rotating shaft, and the cam mechanism rotates with the rotating shaft to push the valve assembly to move downward. When the auto body reaches preset height, a single direction valve attaches to the air intake valve and the air intake valve is closed, so the vehicle body stops rising. With automatic position limit function provided in the process of vehicle body lifting, the model can maintain the vehicle body at preset height.
