ABSTRACT:
Transfer of energy from a relatively high pressure flowing first fluid to a relatively low pressure second fluid is achieved with a master commutator (10) driven solely in response to the flowing first fluid and which separates the first fluid into discrete slugs. Compression waves generated by the pressurized first fluid pressurizes the second fluid in a flow passage (11). The second fluid and first fluid are separately removed from the flow passage by a slave commutator (13) which is synchronized in frequency to the master commutator. In a preferred embodiment the master and slave commutators are fluidis oscillators (20, 21) having no moving parts. The technique has particular utilization as a supercharger for diesel engines.
