Abstract
A diaphragm pump includes an actuator, a diaphragm, and first and second pump chambers and deforms to change a volume of the first pump chamber and a volume of the second pump chamber so that fluid flows. The diaphragm is bonded to a first surface and a second surface of the actuator. When the diaphragm is displaced convexly in a direction to the first pump chamber, the second pump chamber is configured to expand and the first pump chamber is configured to contract so that fluid flows into the second pump chamber and fluid flows out of the first pump chamber. When the diaphragm is displaced convexly in a direction to the second pump chamber, the first pump chamber is configured to expand and the second pump chamber is configured to contract so that fluid flows into the first pump chamber and fluid flows out of the second pump chamber.
