Device for transferring energy between a driving fluid and a driven fluid without contacting or mixing with each other is provided. The device comprises: an elongate central body (44) with a profiled cavity (37, 38) on either side having a respective fluid passage (45,46); a pair of composite outer bodies having a respective fluid in/out passage (35, 36) for fluid communication via a flow diverter valve assembly (15); a pair of assembly of moveable chambers fixed on either side of said central body, disposed inside the composite outer bodies; guiding and connecting means (25, 26) passing through inner annular end plates (47, 48) of composite outer bodies for reciprocating said moveable chambers; wherein said flow diverter valve assembly (15) alternatively diverts the direction of the movement of said moveable chambers by diverting the flow direction of said fluids by actuation or pulses received on reaching respective end position on either side of said central body; and flow directing valves for alternatively directing the flow direction of the other fluid to/from respective moveable chambers via said fluid passages.
