Abstract

An assembly for a tire inflation system includes a ring portion. The ring portion has an outer surface and an inner surface. A first projection and a second projection each extend from the inner surface. A valve assembly is connected to the ring portion and disposed in from the outer surface.

First claim

The invention claimed is:

1. An assembly for a tire inflation system, comprising:
a ring portion having an outer surface and an inner surface, wherein a first projection and a second projection each extend from the inner surface; and
a valve assembly connected to the ring portion and disposed in from the outer surface;
wherein the valve assembly is disposed within a space at least partially defined by a wheel rim and the ring portion.

2. The assembly of claim 1 , wherein the first projection and the second projection are circumferentially spaced apart along the inner surface.

3. The assembly of claim 1 , wherein the valve assembly comprises a first portion and a second portion, the first portion coupled with the first projection and the second portion coupled with the second projection.

4. The assembly of claim 1 , further comprising a center portion with a first end attached to the first projection and a second end attached to the second projection.

5. The assembly of claim 1 , wherein the ring portion comprises a first ring that defines the outer surface, a second ring that is coupled to the first projection and the second projection, and a third ring that is coupled to the second ring, wherein the valve assembly is coupled to the third ring.

6. The assembly of claim 1 , wherein the ring portion is coupled to the wheel rim.

7. The assembly of claim 2 , wherein the first projection and the second projection extend toward each other.

8. An assembly for a tire inflation system, comprising:
a ring portion having an outer surface and an inner surface, wherein a first projection and a second projection each extend from the inner surface; and
a valve assembly connected to the ring portion and disposed in from the outer surface;
wherein the valve assembly comprises a first portion and a second portion, the first portion coupled with the first projection and the second portion coupled with the second projection; and
wherein the first portion and the second portion are in fluid communication.

9. The assembly of claim 4 , wherein the valve assembly is coupled to the center portion.

10. The assembly of claim 4 , wherein the center portion has a first radially extending projection and a second radially extending projection, the first radially extending projection being received in a recess formed in the first projection and the second radially extending projection being received in a recess formed in the second projection.

11. An assembly for a tire inflation system, comprising:
a ring portion having an outer surface and an inner surface, wherein a first projection and a second projection each extend from the inner surface; and
a valve assembly connected to the ring portion and disposed in from the outer surface, wherein the ring portion is coupled to a wheel rim, and
wherein the valve assembly comprises:
i. a housing having a control port and a tire port;
ii. a first portion at least partially disposed within the housing and in fluid communication with the control port, the first portion comprising a valve, wherein the valve prevents fluid communication between the control port and an outlet in a first state and permits fluid communication between the tire port and the outlet in a second state, and
iii. a second portion disposed in the housing and proximate an orifice, the orifice being in fluid communication with the tire port, wherein the second portion prevents fluid communication between the tire port and the first portion or permits fluid communication between the tire port and the first portion.

12. The assembly of claim 8 , wherein the first portion and the second portion are in fluid communication via a fluid conduit formed within the ring portion.
