Abstract
In a rotary feeder, a sealing surface on the end of each compartment defining radial wall is closely spaced from the peripheral surface of the rotor cavity in the housing, a distance that establishes controlled laminar fluid flow between compartments. Preferably, the sealing surface has an approximately uniform spacing from the peripheral surface of the cavity and a matching curvature, and is formed on a blade at least as wide as the radial wall.
