<p>An arrangement in pressure exchangers for transfer of pressure energy from one fluid flow to another, comprising a housing with an inlet and an outlet duct (9, 11, and 10, 12 resp.) for each fluid flow, a rotor (15) which is designed to rotate about its longitudinal axis inside said housing, and which has at least one through duct (16) which extends from one end of rotor (15) to the other end, as seen in an axial direction, and which alternately connects inlet duct (9) and outlet duct (10) of one fluid with outlet duct (12), and inlet duct (11), resp. of the other fluid, and vice versa, during rotation of the rotor. According to the invention the openings of rotor duct (16) are differently spaced from the rotational axis of rotor (15), and substantially in a common plane comprising the longitudinal axis of rotor (15).</p> |
