The disclosure relates to a hydraulic accumulator, in particular a diaphragm accumulator, comprising an accumulator housing and a separating element which is arranged therein and separates two media chambers from each other. The accumulator housing has at least one fluid connection point which opens into an adjacent media chamber and has a connection body with a fluid passage point that is connected to the accumulator housing via a welding seam. The connection body has an annular outer circumferential surface on the connection region facing the accumulator housing, and 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.
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 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, and 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.
A connection body for a hydraulic accumulator, comprising at least one connecting part and one connecting element for the purpose of connecting a fluid pipe or for producing a weld seam joint, wherein the connecting element comprises, on its free end face facing away from the connecting part, starting from an outer circumferential side edge, a flat contact surface or depression, which opens into a fluid passage point which passes through the connecting point and connecting element.
A method for producing a weld joint for a hydraulic accumulator, comprising applying, between a connection body and an adjacently arranged accumulator housing, a laser or electron beam at right angles to and peripherally onto the edge of the connection body on the accumulator housing or respectively onto a transition region between said edge and parts of the adjacently arranged accumulator housing.
