1. A pressure exchanger for transferring pressure energy from a first fluid of a first fluid system to a second fluid of a second fluid system, comprising a liner (12) and two end covers (13 and 14 respectively) with an inlet and an outlet passage (24, 29 and 26, 23 respectively) for each fluid, and a cylindrical rotor (11) which is provided in the liner (12) and which is arranged for rotation about its longitudinal axis, and which has a number of through-going channels with openings at each end arranged symmetrically about the longitudinal axis, where the rotor's channels are arranged for connection with the end covers' inlet and outlet passages in such a manner that during the rotor's rotation they alternately conduct fluid at high pressure and fluid at low pressure of the respective systems, characterized in that one end cover (13) is designed for outlet of ingoing fluid via a central through-bore (25) in the rotor (11) over to an opposite end cover (14) which is arranged for outlet (23) for the first fluid and inlet and outlet (24, 29) for the second fluid. 2. A pressure exchanger according to claim 1, characterized in that the pressure exchanger is mounted in a pressure housing (1) whereby the components are minimally exposed to tension and elastic deformations and protected against impact and shock. 3. A pressure exchanger according to claims 1 and 2, characterized in that the end covers (13, 14) are mounted on each side of the casing (12) via a tension bolt (10). 4. A pressure exchanger according to claims 1,2 and 3, characterized in that the end cover (14) preferably has at least one bottom opening (23) provided with pipe connection and sealing ring for sealing introduction into a corresponding opening (36) in a base (2). 5. A pressure exchanger according to claims 1 and 2, characterized in that the top cover has a multi-sectional locking ring (18) which is arranged to be secured by a central locking cover (20) which has a circular stepped cut-out (19) with an external diameter corresponding to the internal diameter of the locking ring (18), and which can be screwed into the top cover (16) via a securely mounted centre bolt (21). 6. A pressure exchanger according to claims 1 and 2, characterized in that inlet and outlet couplings (5, 7) for high pressure pass through the pressure housing's (1) wall for communication with the end covers' (13, 14) openings for high pressure (26, 29) without sealing engagement. |
