Abstract:
1. A pressure exchanger machine comprising: a housing defining a pressure vessel with first and second compartments and inlet and outlet flow connections; a plurality of exchange ducts statically mounted within said housing; a plurality of valves rotatably disposed within said housing and configured to establish selective fluid communication between said plurality of exchange ducts and at least one of said inlet and outlet flow connections such that during said fluid communication, high or low pressure flows pass through at least one of said first and second compartments and at least one of said plurality of exchange ducts, wherein a first valve of said plurality of valves is operable to direct flow to or from a first end of said exchange ducts and a second valve of said plurality of valves is operable to direct flow to or from a second end of said exchange ducts, wherein each of said first and second valves define an opening formed therein that alternatively connects to respective ends of said exchange ducts; and a first seal disposed between at least one valve of said plurality of valves and a face of said plurality of exchange ducts such that at least one sealing surface is formed between their respective adjacently-facing substantially planar surfaces.
