Abstract
A fluid flow distribution and supply unit for distributing and supplying a fluid is adapted to immediately control a flow rate of a fluid to be distributed and promptly output the fluid at a predetermined flow distribution ratio. The fluid flow distribution and supply unit comprises a flow rate control device for controlling a flow rate of the fluid and a plurality of on/off valves connected to a secondary side of the flow rate control device. The on/off valves are duty controlled to open and close by determining one cycle corresponding to an operation period of the on/off valves and time-dividing the one cycle at the flow distribution ratio.
