Zusammenfassung:PROBLEM TO BE SOLVED: To provide a fluid supply system which can supply a fluid so as to suppress variation of the internal pressure of an introduction chamber of a discharge device to the minimum and thereby suppress poor discharge of the fluid to the minimum and a molding system provided with the fluid supply system.SOLUTION: A fluid supply system 50 includes a supply path 60 connected to a discharge device 20, a pump 80 connected to the supply path 60, a valve 70 capable of cutting off a fluid flow flowing toward the introduction chamber 28 through the supply path 60, and a controller 100 which determines the pressure state on the side of the pump 80 and controls opening and closing of the valve 70 according to the determination results. The controller 100 conducts opening and closing so as to make the valve 70 in an opened state when a pressure state where the pressure P1 on the side of the pump 80 exceeds a specified pressure is determined. 【課題】吐出装置が備える導入室の内圧変動を最小限に抑制し、流動体の吐出不良を最小限に抑制可能なように流動体を供給可能な流動体供給システム、及びこれを備えた成型システムの提供を目的とした。【解決手段】流動体供給システム50は、吐出装置20に接続された供給路60と、供給路60に接続されたポンプ80と、供給路60を介して導入室28に向けて流れる流動体の流れを遮断可能なバルブ70と、ポンプ80側の圧力状態を判定し、判定結果に基づいてバルブ70の開閉制御を行う制御装置100とを有する。制御装置100は、ポンプ80側の圧力P1が所定圧力を超える圧力状態になったものと判定されることを条件として、バルブ70を開状態とする開閉制御を実施する。【選択図】図1
