To provide a fluid supply system capable of reducing size of a tank opening for attaching a valve device.
The fluid supply system includes: hydrogen tanks 10, 10 capable of storing pressurized gaseous hydrogen in interiors; a valve device 20 provided on the hydrogen tank 10; a filling hole 30 positioned in an upstream side of the hydrogen tank 10; a pressure reducing valve positioned in a downstream side of the hydrogen tank 10; a gas filling passage passing hydrogen when filling hydrogen into the hydrogen tank 10 from the filling hole 30 via the valve device 20; and a gas supply passage passing hydrogen when supplying hydrogen from the hydrogen tank 10 via the valve device 20 in a direction of the pressure reducing valve 40. The valve device 20 includes one opening and closing valve adjusting passing of hydrogen by being opened during hydrogen filling and hydrogen supply; a pilot valve arranged coaxially with the opening and closing valve and adjusting pressures applied in an upstream and downstream of the opening and closing valve; an opening and closing valve passage varying passing directions of hydrogen in hydrogen filling and hydrogen supply; and a gas filling passage and the gas supply passage in one fluid passage.
