  "textContent": "The present invention proposes for the first time a spring accumulator piston (1) that is manufactured from plastic, for example using injection molding technology. Furthermore, the spring accumulator piston (1) according to the invention is designed in the region of the connection to a piston or to a piston rod (2) in such a manner that tilting of the spring accumulator piston (1) relative to the piston rod (2) is excluded and a sufficiently secure connection between the spring accumulator piston (1) and the piston rod (2) is ensured. Additionally, the spring accumulator piston (1) according to the invention furthermore has a reinforcement insert (34) by means of which significantly higher forces can be transmitted at smaller wall thicknesses than with conventional spring accumulator pistons. Furthermore, the seat or the contact surface (8) in the spring accumulator piston (1) for supporting the storage spring (12) is designed in such a way that any radial forces that may occur cannot have a negative influence on the functionality of the spring accumulator piston (1).",
