PROBLEM TO BE SOLVED: To provide a fluid pressure pump which enables a discharge amount of fluid to be controlled with a simple configuration while preventing the same from getting large in size.SOLUTION: A fluid pressure pump comprises: a control member 20 which is movable between an open position allowing fluid to flow from a rotor 2 to a discharge port and a closed position keeping the fluid from flowing; and an activation control mechanism C which activates the control member 20. The activation control mechanism C is configured to activate the control member 20: in one direction by a pressure difference between a first fluid pressure chamber S1 and a second fluid pressure chamber S2; and in the other direction by energizing force of an energizing member 26 when pressure in the first fluid pressure chamber S1 and the second fluid pressure chamber S2 reaches a state of equilibrium.SELECTED DRAWING: Figure 1 |
