Abstract

A fluid control apparatus includes a valve and a pump. The valve has a valve chamber surrounded by the first main plate, the second main plate, and the side plate. The first main plate has a first aperture, and the second main plate has a second aperture. The valve further includes a valve diaphragm disposed inside the valve chamber. The valve diaphragm is configured to switch between a state in which the first aperture and the second aperture communicate with each other and a state in which the first aperture and the second aperture do not communicate with each other. The pump includes a vibration unit that has a piezoelectric device and a vibrating plate. The pump has a pump chamber that is defined by the vibration unit and the second main plate. The pump chamber communicates with the valve chamber through the second aperture.
