Beschreibung
Zusammenfassung:	A fluid pressure increasing/decreasing machine 100 capable of continuously supplying an output pressure, includes: a control device 5 switchably selecting at least one input pressure chamber and at least one output pressure chamber from among a head-side pressure chamber 1H and a rod-side pressure chamber 1R of a hydraulic cylinder 1 and a head-side pressure chamber 2H and a rod-side pressure chamber 2R of a hydraulic cylinder, the input pressure chamber being applied with an input pressure, the output pressure chamber creating an output pressure including a pressure higher than the input pressure and a pressure lower than the input pressure; and a flow control valve 6H, 6R, 7H, 7R causing the input pressure chamber and a source of supply SR to communicate with each other, and causing the output pressure chamber and a destination of supply SD to communicate with each other.
