Abstract
An intake manifold assembly is disclosed that utilizes a barrel valve apparatus comprised of segments and connectors. The barrel valve apparatus and its housing component can be tapered and flexible. A protrusion such as a draft can be used to seal the performance of the barrel valve apparatus without a seal. Openings in the barrel valve apparatus can possess an integrated bellmouth shape.

A rotary valve apparatus for use in an intake manifold assembly, said rotary valve apparatus comprising:
- a rotary valve body including a plurality of segments, a plurality of connectors, and a plurality of openings;
- wherein said connectors and said segments are positioned in a substantially sequential manner;
- wherein said rotary valve apparatus is substantially cylindrical in shape;
- wherein said openings are located within said segments;
- and
- wherein said rotary valve body does not include a seal.
A rotary valve assembly, comprising:
- a rotary valve body comprising a plurality of segments, a plurality of connectors, and a plurality of openings, wherein said segments and said connectors are fixed into a substantially horizontal single-file sequence, and wherein each said segment includes at least one said opening, wherein said rotary valve body does not include a seal, and wherein no segment touches any other segment, wherein said rotary valve body is substantially cylindrical in shape;
- and
- a partially enclosed housing component, wherein said rotary valve body is enclosed within said partially enclosed housing component, wherein said openings of said rotary valve body are blocked by said partially enclosed housing component when said rotary valve apparatus is in a closed position, and wherein said openings of said rotary valve body are not blocked by said partially enclosed housing component when said rotary valve assembly is in an open position.
A method for operating a rotary valve apparatus within an at least partially enclosed housing component in an intake manifold assembly, said method comprising:
- rotating a rotary valve body within the housing component to a closed position wherein a plurality of openings within said rotary valve body are blocked and sealed by said partially enclosed housing component;
- and
- rotating the rotary valve body within the housing component to an open position wherein said openings within said rotary valve body are not blocked by said housing component;
- wherein the rotary valve body and the partially enclosed housing component are tapered, wherein the rotary valve body is substantially cylindrical in shape, and wherein the rotary valve body does not include a seal.
