A hydraulic accumulator, especially a bladder accumulator, includes an accumulator housing (10), and a separation element disposed in and separating the accumulator housing interior into a gas chamber (16) adjoining an inlet (14) on the gas side from a fluid chamber (18) adjoining an inlet (20) on the fluid side. The inlet on the fluid side has a fluid connecting neck (22) having a valve support (40) disposed in the neck. The valve support has fluid openings (42), and a disk-shaped valve body (32) that tapers towards the valve shaft (46) on its side facing the valve support (40). The valve shaft can be pretensioned via a force accumulator (62) into the open position releasing the fluid opening, can be displaced into its closed position by a displacement of the separation element (12), and projects into the fluid chamber (18) in the open position. The valve body (32) is an integral, especially one-piece, component of the valve support (40) that is guided along its outer periphery (56) within the connecting neck (22) so as to be displaceable in it, creating a hydraulic accumulator that is comparatively simple and inexpensive in production.
