<p>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.</p> |
