摘要： The object is to reduce the possibility of a longer time of operation of a compressor device (40) in a compressor-pressure supply state in a vehicle-height control system including a tank (34), the compressor device (40), a vehicle-height control actuator (2), and a cut-off valve (63) provided between the tank (34) and the compressor device (40). To achieve the object, the cut-off valve (63) is closed to switch a state of a pressure medium supplier to the compressor-pressure supply state when a tank pressure has reached a threshold value in a tank-pressure supply state in which the tank pressure is supplied to the vehicle-height control actuator (2). In the compressor-pressure supply state, the tank pressure is kept at the threshold value, and a pressure in the vehicle-height control actuator (2) is greater than the tank pressure. The threshold value is a value that makes it difficult for a pressure differential in the cut-off valve (63) to become greater than a valve-opening pressure differential, making it difficult for the cut-off valve (63) to be opened in the compressor-pressure supply state. This construction enables good supply of a pressure medium from the compressor (40) to the vehicle-height control actuator (2), thereby avoiding a longer time for vehicle height control and achieving a shorter time of operation of the compressor (40).
