Tire Inflation System Having a Seal

摘要

A tire inflation system that includes a seal. The seal may have an annular mounting portion and an annular lip portion. The annular lip portion may have a sealing side and a non-sealing side. Leakage of pressurized gas may be inhibited when the sealing side faces away from the annular mounting portion. Leakage of pressurized gas may be enabled when the annular lip portion is rolled such that at least a portion of the sealing side faces toward the annular mounting portion.

主权项

1. A tire inflation system comprising:
a pressurized gas source that provides a pressurized gas for inflating a tire; and a first seal that at least partially defines a connection passage that fluidly connects the pressurized gas source to the tire, wherein the first seal includes:
an annular mounting portion that extends around an axis; andan annular lip portion that extends from the annular mounting portion, wherein the annular lip portion has a sealing side and a non-sealing side disposed opposite the sealing side; wherein the first seal inhibits leakage of the pressurized gas when the sealing side faces away from the annular mounting portion and the first seal enables leakage of the pressurized gas when the annular lip portion is rolled such that at least a portion of the sealing side faces toward the annular mounting portion.
