Beschreibung
Zusammenfassung:	The invention relates to a pressure accumulator (12), especially for a hydraulic unit of a hydraulic vehicle braking system with electronic wheel slip regulation. Pressure accumulators (12) comprising an accumulator piston (22) acted on by a piston spring (36) are known according to prior art. In order to save costs on parts for the piston spring (36) and to save space in terms of the pressure accumulator (12), a piston spring (36) comprising at least one first spring winding (40) is used, the outer diameter of the winding being smaller than the inner diameter of a second spring winding (42) connected thereto.
