Abstract
A liquid supply apparatus includes a compressed air supply source, a pressurizing tank, a feeder, a discharge head, a mitigation device, and a circulation path. The compressed air supply source compresses air. The feeder feeds liquid accumulated in the pressurizing tank to a liquid flow path. The discharge head includes an internal flow path through which the liquid fed from the liquid flow path flows. The discharge head has a nozzle to discharge the liquid from the internal flow path. The mitigation device is installed on the liquid flow path at a position downstream from the pressurizing tank and upstream from the discharge head, and absorbs a fluctuation in pressure of the liquid flowing through the liquid flow path. In the circulation path, the feeder circulates the liquid in the liquid flow path in an order of the pressurizing tank, the mitigation device, the discharge head, and the pressurizing tank.
