Abstract
A rotary joint assembly for a tire pressure management system includes a rotating portion. The rotating portion has a first air passageway and a second air passageway. The first air passageway and the second air passageway are in fluid communication with a chamber formed in the rotating portion. The rotary joint assembly also includes a non-rotating portion. The non-rotating portion has a third air passageway. The third air passageway is in fluid communication with the second air passageway via a sealed space. The sealed space is provided between the rotating portion and the non-rotating portion. A valve assembly is positioned within the chamber. The valve assembly includes a piston and a biasing member. The valve assembly allows a flow of pressurized air to be directed from the first air passageway to the third air passageway or a flow of pressurized air to be directed from the third air passageway to the first air passageway.
