ABSTRACT:
A hydroaccumulator, in particular a bladder accumulator, includes a pressurized container (1) and a separation element (5) located in the container to separate a gas chamber (7) lying adjacent to an inlet on the gas side from a fluid chamber (9) lying adjacent to an inlet on the fluid side inlet (3), having a fluid connecting sleeve (11) and a valve arrangement located in the connecting sleeve (11). The valve body (17) has a transversal bore (33). The valve body is pretensioned in an open position which allows the passage of fluid and can be displaced into a closed position by a displacement of the separation element (5). The interior surface (15) of the connecting sleeve (11) lies directly against the valve body (17) and guides the displacement of the body between the open and closed positions. The side of the valve body (17′) that faces the separation element (5) is configured as a planar plate extending partially into the fluid chamber (9). The diameter of the valve body (17) is greater than its height, measured in the direction of displacement of the valve body (17). The valve arrangement has a plate-valve construction of small proportions and can be cost-effectively produced.
