における切換弁構造。 The hydraulic oil in the tank is pumped up,
This pumped up hydraulic oil is supplied to the hydraulic jack via a supply oil line equipped with a check valve to raise the vehicle height, and the hydraulic oil in the hydraulic jack is transferred to the tank via a return oil line equipped with a check valve. In the vehicle height adjustment device, a spool valve is provided between the supply oil path and the return oil path, and the spool valve is defined by a spool and is configured to lower the vehicle height by discharging the oil. An oil chamber communicating with the oil passage is formed, and a check valve in the return oil passage is closed when hydraulic oil is supplied to the oil chamber of the spool valve, and a check valve in the supply oil passage and a check valve in the return oil passage are closed. A switching valve structure for a vehicle height adjustment device, characterized in that a check valve and a spool valve are incorporated into one valve block.
