ABSTRACT:
A pressure exchanger system having at least two tubular chambers, in which a plurality of reversing valves reverse the flow paths of fluid flows through the at least two tubular chambers. At least one driven reversing valve alternately reverses the flow paths between a supply source, which supplies a high-energy high-pressure fluid, and the tubular chambers. In reversing the liquid flows and shutting off previously open flow paths, the driven reversing element in the reversing valve executes a discontinuous or variable movement sequence.
