- the convex central area of the W-shaped membrane turns So to the edge of the membrane and therefore in the direction of the fastening part into a concave curvature around and despite that in this area intended thickness reinforcement of the membrane is at a variety of Load change games a tearing of the same and therefore a failure of the Storage cannot be ruled out.
- DE-A-1 675 349 is a generic hydropneumatic Pressure accumulator known with a storage housing and a therein, a movable separating element between a first space, in particular Gas space, and a second space, in particular liquid space, forming membrane, which has several ring areas, which over ring-shaped weak points acting in the manner of joints with one another are connected, the ring regions on the wall of the storage housing have elevations facing away from the inside of the membrane, those in the central area between neighboring vulnerabilities greatest height increasing the wall thickness of the membrane and one to these Vulnerabilities falling down and at least in some areas have a convex shape.
- the surveys form annular beads or ribs from the plane of the separating element protrude towards the inside of the membrane and that with its convex Bulges drop steeply in both directions and so into the elongated annular wall areas of the separating membrane. pass over the elevations seen in the longitudinal direction of the hydraulic accumulator in the starting position of the separating element at an equidistant distance from each other be liable. Because of the sharply defined transitions between the bulge or ring-shaped elevations and the weaknesses that come from Parts of the partition element of the same wall thickness are formed, kinks formed in the membrane with the result that it is moving locally overstressed and consequently failing.
- the invention has the task to create a pressure accumulator of the type under consideration, which is characterized by is characterized by a particularly good operating behavior of the membrane, so that a long service life even when operating at high pressure ratios and high pressure change speeds is achievable.
- this object is according to the invention solved in that the surveys at least in the the neighboring vulnerabilities adjacent to the stretched to the Shape of the membrane-related tangential plane of the concerned Weak points to these fall off at a shallow angle, which is less than 20 °.
- the shaping provided according to the invention with the articulation points flat areas of the membrane avoids the risk that too sharp kinks at the joints when folding the membrane be trained, as in the above-mentioned known generic Pressure accumulator is the case. So the harmful notch effect avoided.
- the joint movements take place in the inventive Shaping with a certain radius of curvature, whereby the risk of local overloading of the membrane is avoided is. Without excessive increase in the wall thickness of the membrane are therefore comparatively larger pressure fluctuations and pressure change speeds allowed.
- the weak points have a concave shape, with the membrane an alternating sequence of convex with concave areas given is. This results in particularly good bending and rolling properties when the membrane wrinkles.
