Abstract

An intake manifold assembly has one or more shells coupled together and coupled to a cover. When the manifold cover, or other exterior surface, is rounded, the manifold does not sit stably on a flat surface when the rounded surface is placed onto the flat surface. The manifold may roll off a table and be damaged. To mitigate such situation, the rounded surface is provided with at least two standoffs extending outwardly from a surface of the cover with distal ends of the standoffs substantially lying in a common plane. The standoffs have a central axis and the standoffs extend outwardly from the surface along the central axis at least as far as any other feature of the intake manifold assembly.

First claim

What is claimed:

1. An intake manifold assembly, comprising:
a housing having a rounded outside surface; and
at least one standoff extending outwardly from the outside surface and having a proximal end attached to the outside surface and a distal end opposite the proximal end and farther from the outside surface than the proximal end, the distal end of the standoff substantially lying in a common plane with at least two spaced portions of the outside surface.

2. The assembly of claim 1 wherein the housing has a longitudinal plane coincident with a center of gravity of the assembly, the standoff extending outwardly from the outside surface and increasingly extending farther outwardly from the outside surface along the common plane and away from the longitudinal plane.

3. The assembly of claim 1 wherein the housing includes an elongated polygonal web having an elongated polygonal web portion that comprises a planar end.

4. The assembly of claim 3 wherein the planar end is coplanar with the common plane.

5. The assembly of claim 1 wherein at least one of the two spaced portions of the outer surface comprises a second standoff extending outwardly from an adjacent portion of the outside surface.

6. The assembly of claim 5 wherein:
the housing comprises at least a cover and a middle shell coupled together;
an interface between the cover and the middle shell lies in an interface plane;
the cover has a longitudinal plane coincident with a center of gravity of the assembly and perpendicular to the interface plane;
the standoffs straddle the longitudinal plane; and
the standoffs are at least one-third of a cover width apart.

7. The assembly of claim 1 wherein the housing is substantially comprised of a composite material.

8. The assembly of claim 1 wherein the housing is substantially comprised of an aluminum alloy.

9. The assembly of claim 1 wherein the housing comprises:
a throttle body shell coupled to a top shell;
a middle shell coupled to the top shell;
a bell mouth shell coupled to the middle shell; and
a cover coupled to the bell mouth shell.

10. The assembly of claim 1 wherein:
the housing comprises at least a cover and a middle shell coupled together;
an interface between the cover and the middle shell lies in an interface plane;
the cover has a longitudinal plane coincident with a center of gravity of the assembly and perpendicular to the interface plane; and
the standoff is displaced from the longitudinal plane.

11. An intake manifold having a convexly rounded exterior, comprising:
at least two standoffs extending outwardly from the convexly rounded exterior, each of the standoffs having a proximal end attached to the exterior and a distal end opposite the proximal end and farther from the exterior than the proximal end, the distal ends of the standoffs substantially lying in a common plane with at least two spaced portions of the exterior.

12. The intake manifold of claim 11 wherein the standoffs extend outwardly in a particular direction at least as far as any other feature of the intake manifold.

13. The intake manifold of claim 11 wherein:
the intake manifold has a longitudinal plane perpendicular to the common plane;
the longitudinal plane intersects a center of gravity of the intake manifold;
a pair of the standoffs is substantially symmetric with respect to the longitudinal plane; and
the standoffs straddle the center of gravity of the intake manifold with respect to the longitudinal plane.

14. The intake manifold of claim 11 wherein the intake manifold comprises multiple shells sandwiched together, the shells are comprised of a composite material, and the shells are adhered together via one of friction welding and an adhesive.

15. An intake manifold, comprising:
a first shell;
a rounded cover coupled to the first shell at a coupling interface; and
two standoffs extending outwardly from an exterior surface of the cover, each of the standoffs having a proximal end attached to the rounded cover and a distal end opposite the proximal end and farther from the rounded cover than the proximal end, the distal ends of the standoffs substantially lying in a common plane with at least two spaced portions of the cover wherein the cover has a longitudinal plane perpendicular to the coupling interface and the standoffs straddle a center of gravity of the intake manifold and the longitudinal plane.

16. The intake manifold of claim 15 wherein the standoffs extend outwardly from the exterior surface of the cover beyond any other feature of the intake manifold assembly.

17. The intake manifold of claim 15 wherein the standoffs are formed in one piece with the cover, one of the standoffs lies on one side of the longitudinal plane, and the other standoff lies on the other side of the longitudinal plane.
