Valve assembly for a tire inflation system

An exhaust stem for use with a valve assembly, the exhaust stem comprising:

• a first end portion having a hollow cylindrical shape;
• a middle portion having a hollow ring shape comprising an outer diameter greater than an outer diameter of the first end portion, the middle portion adjacent the first end portion and having a diameter greater than the first end portion;
• and
• a second end portion having a hollow, substantially conical shape, the second end portion comprising:
• a distal end shaped to sealingly engage a valve of the valve assembly, and
• an outer surface defining a plurality of turbulence reducing protuberances,
• wherein the plurality of turbulence reducing protuberances distribute a fluid within a valve housing of the valve assembly to reduce turbulent flow within the valve housing and facilitate operation of the valve assembly.

A valve assembly for use with a tire inflation system, the valve assembly comprising:

• a valve housing defining a valving cavity;
• a valve disposed in the valving cavity of the valve housing, the valve having an annular shape and formed from a resilient material;
• and
• an exhaust stem at least partially disposed in the valving cavity and fixedly coupled with the valve housing, the exhaust stem comprising:
• an inner surface forming a portion of a fluid conduit through the exhaust stem,
• a distal end shaped to sealingly engage the valve, and
• an outer surface defining a plurality of turbulence reducing protuberances, wherein
• the plurality of turbulence reducing protuberances distribute a fluid within the valve housing to reduce turbulent flow within the valve housing and facilitate operation of the valve assembly.
