ABSTRACT:
The three-way valve allows fluid flow to be selectively directed to a run outlet, a bypass outlet or both at the same time. The three-way valve includes a flow diffuser with a primary valve seat positioned opposite a bypass valve seat. Choke points and flow restrictions, strategically positioned in the flow diffuser create a substantially flat velocity profile downstream of the bypass outlet. Larger versions of this three-way valve may be used in Vertical Takeoff and Landing (“VTOL”) aircraft. Other versions may be used in ships and other watercraft.
