Claim:
1. A pressure exchange device configured to exchange pressures between a first fluid and a second fluid, comprising: a rotator configured to rotate about a rotation axis between a first stationary lateral member and a second stationary lateral member, the rotator in which a first flow path, through which the first fluid flows in and out from one end side of the rotator, and a second flow path, through which the second fluid flows in and out from the one end side of the rotator, are arranged around the rotation axis in a direction along the rotation axis; the second stationary lateral member in which there is formed a communication section configured to communicate with the first flow path and the second flow path and exchange the pressures between the first fluid and the second fluid in the communication section; and the first stationary lateral member in which a first fluid inflow path configured to guide the first fluid to the first flow path, a second fluid outflow path configured to guide the second fluid, with a pressure that has been exchanged in the communication section for a pressure of the first fluid, from the second flow path, a second fluid inflow path configured to guide the second fluid to the second flow path, and a first fluid outflow path configured to guide the first fluid, with the pressure that has been exchanged in the communication section for the pressure of the second fluid, from the first flow path, are formed in a thickness direction along the rotation axis, wherein the pressure exchange device further comprises a torque application mechanism configured to apply a torque to the rotator based on an energy of the first fluid that flows into the first flow path or flows out from the first flow path, or an energy of the second fluid that flows into the second flow path or flows out from the second flow path, and wherein the first stationary lateral member includes the torque application mechanism.
