Abstract
A fluid flow metering rotary valve body is provided that includes a central axis, and at least one lobe having at least one fluid opening. At least one fluid throttle is formed on a perimeter surface of the at least one fluid opening. The fluid throttle can have at least one blind void or at least one protrusion and can facilitate various flow strategies, including a decreasing fluid flow with increasing overlap between the fluid opening and a fluid port. The at least one protrusion can extend to various depths to accommodate different fluid openings and injection molding strategies.
