PRESSURE ADJUSTMENT APPARATUS, DROPLET EJECTION APPARATUS, PRESSURE ADJUSTMENT METHOD, AND STORAGE MEDIUM

Abstract: a pressure adjustment apparatus includes: a gas channel configured to form an enclosed space and including a suction-side gas channel at a suction side of a pneumatic pump and a discharge-side gas channel at a discharge side of the pneumatic pump; the pneumatic pump configured to send gas from the suction side to the discharge side; atmospheric relief valves including a suction-side atmospheric relief valve provided to the suction-side gas channel and a discharge-side atmospheric relief valve provided to the discharge-side gas channel; and a hardware processor. in driving the pneumatic pump, the hardware processor controls opening and closing of the atmospheric relief valves to firstly adjust a pressure in the enclosed space formed in one of the suction-side gas channel and the discharge-side gas channel and secondly adjust a pressure in another of the suction-side gas channel and the discharge-side gas channel.
