ABSTRACT:
A pressure exchanger transferring pressure energy from a liquid in a first liquid system to a liquid in a second liquid system, having a housing with inlet and outlet connection openings for each liquid and a rotor arranged in the housing for rotation about a longitudinal axis. Through rotor channels are arranged around the rotor longitudinal axis with openings on each axial end face of the rotor. The rotor channels are arranged for connection through opposing flow openings facing the housing to the connection openings of the housing. During rotor rotation high pressure liquid and low pressure liquid are alternately introduced into the respective systems. Liquid flowing to the rotor through the openings generates a circumferential force (cu) for driving the rotor, and starting at or following the openings a flow guiding configuration formed as a rotor channel flow diverting contour is arranged in the rotor channels.
