Abstract
A hydraulic accumulator, especially a piston accumulator includes an accumulator housing () and a separating piston that can be longitudinally displaced in the accumulator housing () and divides two working chambers () inside the accumulator housing (). The housing is sealed on each end by one cover part (). At least one cover part is fixed, on one side () by a free longitudinal edge () of the accumulator housing (). The edge is arranged against the cover part (). By connecting the free longitudinal edge () of the accumulator housing () to the associated cover part () by a peripheral weld seam () for sealing at least one working chamber () from the environment in a gas-tight and/or fluid-tight manner, a reliable sealing is obtained by the weld seam (). The weld seam also connects the free longitudinal edge () of the accumulator housing () to the associated cover part ().
