Disclosed is a pressure exchanger 10 provided with: a rotator 30 disposed with pressure transmission sections 33 around a rotation axis, each pressure transmission section 33 being so formed that a first flow path 31, into or out of which first fluid flows from one end side, and a second flow path 32, into or out of which second fluid flows from the one end side, are communicated with each other; a first lateral member 20a formed with first fluid inflow paths 14 guiding the first fluid to the first flow paths 31, second fluid outflow paths 15 guiding, from the second flow paths 32, second fluid obtained after pressure exchange with the first fluid, second fluid inflow paths 16 guiding the second fluid to the second flow paths 32, and first fluid outflow paths 17 guiding, from the first flow paths 31, first fluid obtained after pressure exchange with the second fluid in the thickness direction; and a second lateral member 20b rotatably sandwiching the rotator 30 between the second lateral member 20b and the first lateral member 20a via bushes 13, wherein downsizing and low cost are attained. |
