PCT No. PCT/NO90/00162 Sec. 371 Date Jun. 29, 1992 Sec. 102(e) Date Jun. 29, 1992 PCT Filed Oct. 30, 1990 PCT Pub. No. WO91/06781 PCT Pub. Date May 16, 1991.A pressure exchanger for transfer of pressure energy from one fluid flow to another in a housing having inlet and outlet ducts for each fluid flow and a rotor adapted to rotate about its longitudinal axis within the housing. The rotor is formed with a plurality of rotor ducts arranged around the axis of rotation, the rotor ducts extending from one end of the rotor to the other and having openings at the ends which alternately connect the inlet and outlet ducts of the respective fluids to one another during rotation of the rotor. The rotor is frusto-conical in shape and the openings at the larger diameter end of the rotor are spaced from the axis of rotation at a distance which is substantially greater than the radial spacing of the openings at the smaller end of the rotor. The openings at the smaller end of the rotor are located in proximity to the axis of rotation of the rotor and the openings at the larger end of the rotor are disposed in a narrow annular region in proximity to the periphery of the rotor.
