Abstract: A valve for redirecting fluid flow has a valve chamber (16) supporting fluid flow, with the valve chamber having an inlet (25), a first outlet (26), and a second outlet (28). The valve chamber (16) can be closed or partially open. A flap element (24) is movable to alternatively block the first outlet (26) and the second outlet (28). In or immediately adjacent to the valve chamber (16) are opposing first and a second catch mechanisms (34,36) for controllably latching the flap element to block respectively the first outlet and the second outlet. The first and second catch mechanisms (34,36) have a disabled state and an activated state for holding and allowing release of the flap element (24). Once the first or second catch mechanism is disabled, the flap element (24) is free to move to another position, provided it can overcome the mechanical fluid flow forces that tend to hold it in position. To counter and utilize such forces for moving the flap element, an impulse mechanism kicks the flap element into the valve chamber, away from one of the first and second catch mechanisms, after one of the first and second catch mechanisms is controllably brought into the disabled state. Since the flap element is unstable, oscillations of the flap element in the fluid flow will eventually bring the flap element into catchment range of one of the first and second catch mechanisms in an activated state.
