  "textContent": "The present invention proposes for the first time a spring accumulator piston (1) which 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) such that tilting of the spring accumulator piston (1) relative to the piston rod (2) is excluded and a sufficiently firm connection between spring accumulator piston (1) and piston rod (2) is ensured. In addition, the spring accumulator piston (1) according to the invention furthermore has a reinforcing insert (34), by means of which significantly higher forces can be transmitted with 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 such that any radial forces that may occur cannot have a negative influence on the functionality of the spring accumulator piston (1).",
