Automatic Tire Pressure Management Systems and Methods

A valve subassembly for use in a tire inflation assembly associated with a tire and having a fluid chamber configured to receive fluid from a fluid supply source, the valve sub-assembly comprising:

• a first fluid valve;
• and
• a second fluid valve,
• wherein both the first fluid valve and the second fluid valve are disposed between and in fluid communication with the fluid chamber and with the tire,
• and wherein the first fluid valve is configured to open responsive to a pressure differential between the fluid chamber and the tire, and the second fluid valve is configured to open responsive to pressure in the fluid chamber being greater than a first pressure threshold.

A method for manufacturing a tire inflation assembly for operative connection to a fluid supply source and to be associated with at least a first tire when in operation, the method comprising:

• defining, at least partially by a housing comprising a fluid supply port, a fluid chamber in fluid communication with the fluid supply port when in operation;
• connecting a first valve subassembly to the housing, the first valve subassembly in fluid communication with the fluid chamber when in operation, and the first valve subassembly comprising a first fluid valve and a second fluid valve each disposed between and in fluid communication with the fluid chamber and with the first tire when in operation;
• configuring the first fluid valve to open responsive to a pressure differential between the fluid chamber and the first tire when in operation;
• and
• configuring the second fluid valve to open responsive to pressure in the fluid chamber being greater than a first pressure threshold when in operation.
