Claim Text:
1. A pressure exchanger for exchanging pressures between a first fluid and a second fluid, the pressure exchanger comprising: a rotator having, around a rotation axis, a pressure transmission section provided such that a first flow path into or out of which the first fluid flows from a first end of the rotator is communicated with a second flow path into or out of which the second fluid flows from a first end of the rotator; a first lateral member provided, in a thickness direction along the rotation axis, with a first fluid inflow path for guiding the first fluid to the first flow path, a second fluid outflow path for guiding the second fluid after the exchanging of pressures from the second flow path, a second fluid inflow path for guiding the second fluid to the second flow path, and a first fluid outflow path for guiding the first fluid after the exchanging of pressures from the first flow path; and a second lateral member, wherein the rotator is rotatably sandwiched between the first lateral member and the second lateral member, with a retentive member being interposed therebetween, wherein the rotator is accommodated in a space defined by the first and second lateral members, and the retentive member is sandwiched between the lateral members, the first flow path and the second flow path pass through the rotator, and gaps into which the first fluid and the second fluid flow are provided between the rotator and the first and second lateral members, respectively, and wherein the first and second lateral members are provided outside the rotator with press spaces pressing the lateral members toward the rotator, and the first and second lateral members are provided with continuous holes for guiding at least one of the first fluid and the second fluid supplied to the first flow path or the second flow path into the press spaces.
