Abstract: A plunger pressure accumulator includes a shell; and a plunger which is adapted to move relative to the shell into an interior space of the shell. The interior space is divided into at least two subspaces, a first subspace of which is suppliable with hydraulic fluid of an external system and a second subspace which is provided with a pressurized gas. Between the plunger and the shell is arranged a slide element upon which the plunger is supported to move to a distance apart from an internal surface of the first subspace and from an internal surface of the second subspace. The plunger pressure accumulator is provided with at least one regenerator which is stationary relative to the shell or the plunger.

Abstract: The invention relates to a plunger pressure accumulator (1), comprising: a shell (2); a plunger (3; 30) which is adapted to move relative to the shell (2) into an interior space of the shell (2). The space is divided into at least two subspaces (4 and 5), the first subspace (4) of which is suppliable with the hydraulic fluid of an external system and the second subspace (5) is provided with a pressurized gas. Between the plunger (3; 30) and the shell (2) is arranged a slide element (2a; 2b') upon which the plunger (3) is supported to move to a distance apart from an internal surface (4a) of the first subspace (4) and from an internal surface (5a) of the second subspace (5). The plunger pressure accumulator (1) is provided with at least one regenerator (7a; 7b; 8) which is stationary relative to the shell (2) or the plunger (3).

Abstract: The object of the invention is a method for producing pressurized gas. Therein, gas to be pressurized is directed into one or more closable gas spaces (3, 103, 203) of compressor means (1, 100, 200), the gas directed into the gas space is pressurized, and the pressurized gas is released and/or transferred for further processing. The gas space (3, 103, 203) is fitted with an adsorption material (7, 107, 207), wherein in order to pressurize the gas: molecules of the gas directed to the gas space are adsorbed to an adsorption material (7, 107, 207), the adsorption material is heated in order to create a desorbing effect on the molecules of the adsorbed gas by means of heating means (8, 108, 208) arranged in connection with the gas space (3, 103, 203) and/or adsorption material (7, 107, 207), which heating means have been arranged to utilize waste heat or renewable energy from an external system (10). The gas pressurized as a result of the desorption in the closed gas space (3, 103, 203) is re leased and/or transferred into an external high-pressure space, a pressure accumulator, an external system (40, 120) and/or an internal primary circuit (6b, 106b) of the compressor (1, 100, 200) in order to utilize the waste heat or renewable energy stored in the pressurized gas. The object of the invention is also an arrangement applying the method.
