Abstract

The invention relates to a piston pressure accumulator (1), comprising: a frame (2); a piston (3; 30), which is arranged to move relative to the body (2) of the body (2) in the interior space. The space is divided into at least two subspaces (4 and 5), of which a first partial space (4) is supplied to the external system hydraulic fluid and a second partial space (5) is a compressed gas. The piston; between (3 30) and the body (2), the slide element (2a; 2b '), on which the piston (3) is supported to move in a distance from the first partial space (4) from the inner surface (4a) and a second partial space from the inner surface (5a). Mäntäpaineakkuun (1) is provided with at least one regenerator (7a; 7b; 8) which is stationary relative to the body (2) and the piston (3).
