  • Fluid controller with multiple fluid meters
    Patent number: 8225603
    Abstract: A fluid controller includes a first fluid meter defining a first plurality of volume chambers and a second fluid meter defining a second plurality of volume chambers. A selector assembly, disposed between the first fluid meter and the second fluid meter, includes a selector plate defining a bore and a selector valve disposed in the bore. The selector valve is adapted for rotational movement between a first position and a second position and includes a first face and an oppositely disposed second face. The selector valve defines a plurality of thru-passages that extend axially through the first and second faces and that is adapted to provide fluid communication between the first and second volume chambers in the first position. The selector valve defines a groove disposed on the second face. The groove recirculates fluid from the second plurality of volume chambers when the selector valve is in the second position.
