Abstract

The invention relates to an adaptive hydraulic pressure generator (10) for systems in which the mechanical force producing energy varies significantly, especially for wave energy systems. The pressure generator comprises at least two fluid chambers (11, 12; 201, 202; 301, 302, 303; 401, 402, 403) with a piston surface/displacement surface (A1y, A1a, A2y, A2a), which piston surface/displacement surface and fluid chamber are arranged to reciprocate with respect to one another, whereby the piston surface/displacement surface (A1y, A1a, A2y, A2a) acts on the fluid in the chamber (11, 12; 201, 202; 301, 302, 303; 401, 402, 403) by means of the said mutual reciprocating movement. The pressure generator is arranged to produce a pressure exceeding a certain threshold pressure in the fluid supplied to the application. The pressure generator (10) is equipped with a control system (18) which is arranged to connect the chambers to each other and/or to different pressure ducts in such a way that the effective area (Aeff) of the piston/displacement surfaces (A1y, A1a, A2y, A2a) changes in accordance with the changes in the driving force exerted on the piston/displacement surfaces (A1y, A1a, A2y, A2a) and/or the body forming the fluid chamber in such a way that the pressure produced-by the-pressure generator in the fluid supplied to the application exceeds the threshold pressure.
