A bootstrap hydraulic reservoir (112, 212, 312, 412, 412, 612) includes a bootstrap chamber (114, 214, 314, 414, 514, 614) to hold hydraulic fluid, a piston chamber (116, 216, 316, 416, 516, 616) fluidly connected to a pressure line (110, 210, 310, 410, 510, 610) of the hydraulic fluid system (100, 200, 300, 400, 500, 600, 712), a piston (118, 218, 318, 418, 518, 618) having a bootstrap end portion (138) held within the bootstrap chamber (114, 214, 314, 414, 514, 614) and a pressure end portion (140) held within the piston chamber (116, 216, 316, 416, 516, 616), and a hydraulic accumulator (120, 220, 320, 420, 520, 620) fluidly connected to the pressure line (110, 210, 310, 410, 510, 610) of the hydraulic fluid system (100, 200, 300, 400, 500, 600, 712). The hydraulic accumulator (120, 220, 320, 420, 520, 620) accumulates pressurized hydraulic fluid from the pressure line (110, 210, 310, 410, 510, 610). The bootstrap hydraulic reservoir also includes a valve (122, 222, 322, 422, 522, 622) fluidly connected to the pressure line (110, 210, 310, 410, 510, 610) of the hydraulic fluid system (100, 200, 300, 400, 500, 600, 712) between the hydraulic accumulator (120, 220, 320, 420, 520, 620) and an outlet (108, 208, 308, 408, 508, 608) of a pump (104, 204, 304, 404, 504, 604) of the hydraulic fluid system (100, 200, 300, 400, 500, 600, 712). The valve (122, 222, 322, 422, 522, 622) includes an actuator (158, 258, 358, 458, 658) selectively moves the valve (122, 222, 322, 422, 522, 622) to an open position when the pressure line (110, 210, 310, 410, 510, 610) of the hydraulic fluid system (100, 200, 300, 400, 500, 600, 612) is de-pressurized.
