A piston-type accumulator includes an accumulator housing provided in the form of a cylinder tube ( 1 ). A separating piston ( 15 ) separates two working spaces ( 5 ) and ( 6 ) from one another in the housing and can be displaced in an axial direction within a piston stroke area ( 19 ) of the cylinder tube ( 1 ). The cylindrical tube is closed at one axial end by a closure part ( 7 ). The closure part is defined by deforming a deforming area ( 9 ) of the wall of the cylinder tube ( 1 ). The deforming area adjoining the piston stroke area ( 19 ) is provided in the form of part that exists as a single piece with the housing. A stop body ( 25 ), which limits the movement of the separating piston ( 15 ) before reaching the deforming area ( 9 ), is provided inside the cylinder tube ( 1 ) at the location where the piston stroke area ( 19 ) transitions into the deforming area ( 9 ).
