Abstract
A hydroaccumulator, especially a membrane accumulator, has an accumulator housing with two housing parts and a separating element in the housing. The separating element can be a separating membrane dividing the accumulator housing into a gas chamber and a fluid chamber. The gas chamber is connected to carry gas to and from gas refiller through a connection. The gas refiller is formed from an additional housing part connected to the accumulator housing to form a unit. The connection is at least one connecting opening in the accumulator housing connecting the interior of the additional housing part to the gas chamber. Additional gas accumulator volume is provided without otherwise conventional pipework to save money and installation space and avoid conventional leaks which occur in the area of the pipework.
