  • Patent number: 12083844
    Abstract: A highly reliable and highly efficient air suspension system for a vehicle is provided by improving the trackability of stroke control with respect to pressure fluctuations applied to a linear compressor, suppressing stroke increase due to pressure drop, preventing piston collision, and increasing a flow rate by reducing dead volume. To realize this, the air suspension system includes an air suspension that supplies and discharges compressed air to adjust a length, a compressor body in which a piston reciprocates in a cylinder to compress air, a linear motor that reciprocates the piston, a tank that is connected to the air suspension or the compressor body and stores compressed air, a solenoid valve that opens and closes the air suspension or the tank, and an inverter that changes power supplied to the linear motor according to an open and closed state of the solenoid valve to perform position control of the piston.
