PROBLEM TO BE SOLVED: To provide a device for controlling fluid supply of a system, which attains further simplification and further reduces manufacturing cost.SOLUTION: A device comprises an inlet 8, an outlet 10 of pressurized fluid, a main conduit 11 connecting the supply inlet 8 and the discharge outlet 10, and a control means. The device further comprises an auxiliary duct 12 connecting the supply inlet 8 to the discharge outlet 10, a movable seal element 14 interrupting a flow in the main conduit 11, a seal means capable of interrupting a flow in the auxiliary duct, and a guide chamber 18 connected to the supply inlet 8 and lying between the movable seal element 14 and the seal means. In a state that the seal means is closed, the movable seal element 14 interrupts fluid circulation between the supply inlet 8 and the discharge outlet 10, and in a state that the seal means is opened, the movable seal element allows a fluid flow between the supply inlet 8 and the discharge outlet 10. |
