Beschreibung
Zusammenfassung:	The present invention pertains to a plug assembly (16) and a method to maintain and eliminate a fluid pressure in an accumulator tank (9). The plug assembly (16) comprises a fastening device (18), with which the plug assembly may be fastened to a connecting section (10) of the accumulator tank (9), a sleeve-shaped device (20) with an internal space (20a), where a lower pressure prevails than in the accumulator tank (9), a manoeuvring device with which a locking body (19) may be moved between a closed position, in which it blocks an opening (10b) of the connecting section (10) and an open position in which it exposes the said opening (10b) of the connecting section, and a flow passage connecting the pressurised fluid in the accumulator tank (9) with the internal space (20a) of the sleeve-shaped device (20), at times when the locking body (19) is in the open position.
