Abstract

A connection system for sealingly interconnecting components of a high pressure fluid flow system, for example, an automobile engine air intake. The system can include a conduit defining a groove that is locked in a corresponding groove defined by a component, for example, an engine intake. An interlock ring is placed in the conduit groove. A clamp is placed over the interlock ring, however, the clamp and ring can be an integral component. When tightened, the clamp forces the ring into the conduit groove, which presses the conduit into sealing and/or locking engagement with the component groove.

Claims (26)

1. An automobile air intake apparatus comprising:

an intake defining an intake groove;

a flexible conduit including an interior, an exterior and an end, the exterior defining a conduit groove around the end, the conduit groove reflected as a projection on the interior, the projection seated within the intake groove, thereby mating the conduit to the intake in a fixed position;

a discontinuous interlock ring positioned over the conduit end and in the conduit groove without exerting a substantial clamping force on the conduit, the discontinuous interlock ring including opposing ends; and

a clamp positioned over the end to clamp the conduit end to the intake,

wherein the clamp compresses the discontinuous interlock ring into the conduit groove to drive the conduit projection into sealing engagement with the intake groove on the intake, the ends of the discontinuous interlock ring being brought nearer one another as the projection is driven into sealing engagement with the intake groove on the intake,

wherein the clamp continues to compress the discontinuous interlock ring within the conduit groove and remains positioned over the end of the conduit to maintain a connection between the end and the intake as the intake intakes air.

2. The automobile air intake apparatus of claim 1 wherein the conduit groove is of a substantially semicircular cross section.

3. The automobile air intake apparatus of claim 2 wherein the discontinuous interlock ring is of a circular cross section that mates with the semicircular cross section of the conduit groove.

4. The automobile air intake apparatus of claim 3 wherein the discontinuous interlock ring is constructed from metal.

5. The automobile air intake apparatus of claim 1 wherein the discontinuous interlock ring and the clamp are joined with one another so that the ring is on an interior portion of the clamp facing the conduit.

6. The automobile air intake apparatus of claim 1 wherein the discontinuous interlock ring is separate from the clamp and adjacent an interior portion of the clamp facing the conduit.

7. The automobile air intake apparatus of claim 1 wherein the clamp drives the conduit projection into sealing engagement with the intake groove without substantially deforming the intake groove.

8. A connection assembly comprising:

a component defining a component groove;

a conduit defining a conduit groove, the conduit fitted over the component so that the conduit groove interlocks with the component groove to secure the conduit to the component;

an interlock ring including opposing ends, the interlocking ring positioned in the conduit groove;

a clamp clamping the interlock ring into the conduit groove so that the conduit is forced into at least two points of sealing engagement with the component groove,

the clamp remaining adjacent the conduit to retain the interlock ring in the conduit groove and to maintain the sealing engagement as fluids pass through the component and the conduit at pressures that are at least 15 psi.

9. The connection assembly of claim 8 wherein the interlock ring is integral with the clamp.

10. The connection assembly of claim 8 wherein the opposing ends draw closer to one another when the clamp clamps the interlock ring into the conduit groove.

11. The connection assembly of claim 8 wherein the component is an intake for an engine.

12. The connection assembly of claim 8 wherein the conduit is a tube constructed from a flexible, resilient polymer.

13. The connection assembly of claim 12 wherein the conduit includes an interior and an exterior, the polymer having a harder durometer on the exterior than on the interior.

14. The connection assembly of claim 8 wherein the interlock ring partially circumferentiates the conduit, and wherein the conduit fully circumferentiates the component.

15. The connection assembly of claim 8 wherein the conduit is deformed without the component groove being substantially deformed.
