Abstract
A method for producing a foam body for a pressure or hydraulic accumulator has a bubble- or diaphragm-shaped, elastically flexible separating layer () separating gas and liquid chambers from each other within an accumulator housing. The production method includes introducing a flowable, preferably liquid, foam material into the pressure accumulator with the foam material being at least partially surrounded by the separating layer (), curing the foam material in the hydraulic accumulator, and building up a pressure gradient in which the visibly curing foam material expands the separating layer () from an originally partially filled starting state in the direction of an end state in which the accumulator is finally filled with the cured foam ().
