| 摘要 |
An apparatus for controlling a fluid flow is disclosed herein. The apparatus includes first and second spaced walls defining opposite sides of a first fluid passageway extending along a first axis. At least one of the first and second walls is cantilevered along the first axis and includes a distal end moveable relative to the first axis. The distal end of the at least one wall is moveable in response to changes in the flow temperature to passively vary a size of the first fluid passageway.
