Abstract
A valve includes a valve housing having a fluid inlet and a fluid outlet with a longitudinal axis defined through the valve housing. The valve also includes a toggle mechanism configured and adapted to cycle flow from the fluid inlet to the fluid outlet through a plurality of different flow rates in response to repeated impulses. The toggle mechanism is also configured to hold flow rate steady between impulses.
