Hydraulic accumulator

A hydraulic accumulator, comprising an accumulator housing and a separating element which is arranged therein and separates two media chambers from each other, the accumulator housing comprising at least one fluid connection point which opens into an adjacent media chamber and has a first connection body with a fluid passage point that is connected to the accumulator housing via a welding seam;

• wherein
• the connection body has an annular outer circumferential surface on the connection region facing the accumulator housing;
• wherein when the end face of the connection body is placed on the accumulator housing, the connection body forms a transition point, along which the welding seam runs;
• wherein
• the outer circumferential surface of the connection body transitions into a peripheral edge at its free end, from which edge a depression made in the end face of the connection body is connected;
• wherein the course of the depression in the connection body is adapted to a curved accumulator housing wall, which has a convex curvature in the region of the welding seam, viewed in cross-section, and which at least partially engages in the depression and which surrounds a further fluid connection point wherein the depression forms an annular come with a shallow inclination of 4° to 10°.
