摘要： A compressor system for receiving a gas fluid and discharging the gas fluid at a higher pressure. The system comprises at least one compressor and at least one piston intensifier associated with each compressor. Each piston intensifier has a double-acting piston, with one piston head reciprocating in an actuation cavity and the other piston head reciprocating in a high pressure cavity. The compressor delivers its output flow to both cavities of the piston intensifier, alternating between below and above their piston heads, to provide both a working (actuation) fluid and a fluid to be compressed and discharged. A return flow from the actuation cavity back to the compressor also alternates to recycle the working fluid.

摘要： 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.

摘要： A method of compressing gas includes maintaining a volume of gas at a first pressure within a first chamber. Pressurized liquid is forced into the first chamber through a nozzle having a curved profile. Based on the Coanda effect, the liquid compresses the volume of gas to a second pressure greater than the first pressure. The liquid is separated from the gas in a second chamber while maintaining the gas at the second pressure to provide compressed, dry gas.
