Abstract:
A method of improving flow from an axially-rotated valve using a split venturi comprising:a. flowing through a flow path having a pressure and velocity wherein said flow path has a flow path periphery;b. entering a first portion of an eccentric split venturi;c. gradually reducing said pressure of said flow while increasing said velocity of said flow through said first portion of said eccentric split venturi;d. flowing across an interface of said split venturi between said first portion and a second portion, said second portion contained within a venturi sleeve periphery which does not extend substantially beyond said flow path periphery;e. gradually increasing said pressure of said flow while decreasing said velocity of said flow through said second portion of said eccentric split venturi;f. exiting said second portion through an exit port fluidicly connected to said second portion;g. axially rotating said second portion of said eccentric split venturi to at least a partially closed position;h. at least partially restricting said flow from flowing through said axially-rotated valve at said interface;i. rotating said second portion of said eccentric split venturi to at least a partially open position;j. allowing said flowing through said axially-rotated valve.
