Abstract:
PCT No. PCT/NO87/00086 Sec. 371 Date Sep. 2, 1988 Sec. 102(e) Date Sep. 2, 1988 PCT Filed Dec. 30, 1987 PCT Pub. No. WO88/05133 PCT Pub. Date Jul. 14, 1988.A pressure exchanger for transfer of pressure energy from a liquid flow of one liquid system to a liquid flow of another liquid system includes a housing (1) with inlet and outlet ducts forming pairs of ducts for each liquid flow. A cylindrical rotor (8) is rotably arranged in the housing (1), the rotor having a number of axial bores adapted to sequential connection with the passages and thus alternately carry liquid of high pressure of the respective systems. According to the invention the duct openings facing the rotor (8) are found approximately as a segment with a control angle of 180 DEG and a partition wall is formed between these openings. These large openings permit fast liquid flows which fluctuate only to a slight extent.
