Patent Images
1. A valve assembly for a tire pressure management system, comprising:
- a housing which comprises a valve cavity;
a cage member positioned within the valve cavity, the cage member in a sealed relationship with the housing;
a piston moveable within the cage member; and
a biasing member provided in a biasing member cavity portion of the valve cavity, the biasing member contacts an end of a stem portion of the piston to urge the piston away from the biasing member cavity portion, wherein the end of the stem portion is positioned in the biasing member cavity and the biasing member is not provided in a flow pathway of pressurized air through the valve assembly.

18. A valve assembly for a tire pressure management system, comprising:
-
a housing which comprises a valve cavity, a first fluid conduit in fluid communication with the valve cavity and another portion of the tire pressure management system, a second fluid conduit in fluid communication with the valve cavity and selectively in fluid communication with the first fluid conduit, and a third fluid conduit in fluid communication with the valve cavity and selectively in fluid communication with the first fluid conduit; a cage member positioned within the valve cavity, the cage member in a sealed relationship with the housing; and a piston moveable within the cage member, the piston comprises a first end surface and a second end surface, the first end surface and the second end surface define opposite ends of the piston, wherein the first end surface is configured to receive a pneumatic signal and the second end surface is configured to be contacted by a biasing member to urge the piston away from an end of the valve cavity, and when the pneumatic signal is not received by the first end surface the first fluid conduit is in fluid communication with the second fluid conduit which allows pressurized air to flow from the first fluid conduit to the second fluid conduit, the biasing member not being within a flow pathway of the pressurized air from the first fluid conduit to the second fluid conduit. - View Dependent Claims (19, 20)
