Abstract
Air valve for a pneumatic tire has a threaded shaft between a first end defining an air inlet and an opposite, second end that is located within the bounded space of a tire mounted on a rim. The air passageway through the air valve has at least one outlet at the distal end of the valve that exists the device through a side portion rather than the terminal end of the device. In a preferred embodiment the air passageway is T-shaped so that air flowing into the tire flows in a non-linear path, exiting the air outlets transverse to the air flow through the inlet into the air passageway.
Claims20
An air valve for a tubeless pneumatic tire assembly including a rim, a tire mounted on the rim and an annular insert mounted on the rim such that the annular member is disposed between the rim and the tire, the air valve, comprising:
- a shaft having a proximate end and a distal end having a base with an enlarged size relative to the size of the shaft at the proximate end, the base portion defining a base sidewall portion and a base terminal end portion adapted to be in contact with the annular insert;
- and
- an air passageway extending from an air inlet at the proximate end to an air outlet extending through the sidewall portion of the base to define an air passageway through the shaft that is not occluded by the annular insert.
An air valve for a tubeless pneumatic tire assembly including a rim, a tire mounted on the rim and an annular insert mounted on the rim such that the annular member is disposed between the rim and the tire, the air valve, comprising:
- a shaft having an air passageway therethrough, the air passageway and extending from an air inlet to at least one air outlet adjacent to the annular insert and wherein the air passageway is non-linear from the air inlet to the air outlet and the outlet is not occluded by the annular insert.
An air valve for a tubeless pneumatic tire assembly including a rim, a tire mounted on the rim and an annular insert mounted on the rim such that the annular member is disposed between the rim and the tire, the air valve, comprising:
- a shaft having a first end and a second end;
- a base on the second end, the base having a base sidewall portion and a base terminal end portion positioned between the rim and the annular insert;
- an air passageway extending from an inlet at the first end to an outlet through the sidewall portion of the base;
- and
- a shut-off valve in the air passageway.
