Abstract
The invention relates to a hydraulic accumulator, especially a piston-type accumulator, comprising an accumulator housing (10) as well as at least one gas chamber (12) that is arranged therein and a fluid chamber (14) which are separated from each other via a separating element (16), particularly in the form of a piston. One free end of the accumulator housing (10) is sealed via a valve block (24) that is provided with a ball valve (28) which opens or blocks a fluid-guiding path (30) from the interior of the accumulator housing (10) towards the outside in the open position or closed position thereof such that the ball valve forms an integral part of the accumulator housing via the valve block and is thus accommodated in a compact manner within the hydraulic accumulator solution, also resulting in a reduction of the free fluid paths and therefore a reduction of tubing.
