Abstract: A pressure exchanger with a valve system includes a cylinder barrel (1), two valve plates (2) and two port plates (3, 4), wherein the cylinder barrel (1) has at least one cylinder (7) which accommodates a piston (8). The objective is to provide a pressure exchanger with low wear and a low maintenance effort. This objective is solved by a pressure exchanger including a piston (8) braking system and that the piston (8) includes a pressure relief arrangement.
