Automatic Level Control: Operation

As rear of vehicle is lowered due to added weight, the leveling valve lever raises to the filling position. This allows fluid to flow from pump to pressure reservoir then to special shock absorber, through check valves.

This added fluid will raise the rear of the vehicle until the leveling valve lever is moved back to the neutral position. When the added weight is removed, rear of vehicle raises which moves the leveling lever to the return flow position.

This allows the fluid in the special shock absorber to drain back into the reservoir until the leveling lever is back in the neutral position and the vehicle is level.
