る車高調整装置。 ゛Among the air lines that connect the air tank that supplies compressed air and the air spring that changes the vehicle height by supplying and discharging compressed air, the side closest to the air tank is demagnetized by flowing compressed air when it is energized. and the first opening to the atmosphere.
and a second electromagnetic air valve on the side near the air spring that allows compressed air to flow through it when it is energized and connects to another air line that is connected to the air tank via a leveling valve when it is demagnetized. Furthermore, a third electromagnetic valve is installed between the first and second electromagnetic air valves, which allows compressed air to flow when it is energized and blocks the flow of compressed air when it is demagnetized. , a main switch that energizes the second electromagnetic air valve when turned on and demagnetizes the second electromagnetic air valve when opened; When the third electromagnetic air valve is energized and applied to the down contact, the first electromagnetic air valve is demagnetized, the third electromagnetic air valve is energized, and has a stop position where the current is cut off without being applied to either the deep contact or the down contact. A vehicle height adjustment device comprising a first vehicle height adjustment switch, and a second vehicle height adjustment switch outside the driver's cab that performs the same function as the first vehicle height adjustment switch.゛
