Beschreibung
Zusammenfassung:	A hydraulically actuated braking system (3) for a work vehicle (1), comprising: variable flowrate pumping means (5), which are adapted to suck a hydraulic fluid from a tank (6) and are adapted to provide at outlet a pressurized flow of the hydraulic fluid; a hydraulic accumulator (8), which is fluidly connected downstream to the variable flowrate pumping means (5) and is adapted to store the pressurized hydraulic fluid fed by the variable flowrate pumping means (5); a hydraulically actuated brake assembly (9), which is operatively coupled to a wheel assembly of the work vehicle (1) and is fluidly connected to the hydraulic accumulator (8); a brake input device (11), which is adapted to be operated to control the operation of the brake assembly (9); and a brake actuation valve assembly (12), which is fluidly interposed between the hydraulic accumulator (8) and the brake assembly (9), is operatively connected to the braking input device (11), and is configured to control the flow of the pressurized hydraulic fluid from the hydraulic accumulator (8) to the brake assembly (9) according to the actuation of the braking input device (11).
