Abstract
A fluid control apparatus configured to be able to reduce electric power consumption required for opening/closing operations of a fluid control valve includes a valve body and a valve seat one of which is formed of a magnetic material and the other of which includes a magnet, the valve body and the valve seat being incorporated in a fluid flow passage and movable to come into contact with or away from each other to control communication of fluid, an urging member configured to urge the valve body toward the valve seat, an electric pump for flowing the fluid in the flow passage, and a control section for effecting control to increase an output of the electric pump to a preset state when the valve body under a closed state as being in contact with the valve seat is to be opened.
