Pressure equalization valve assembly

A valve assembly comprising:

• a valve body forming a fluid chamber configured to receive constant pressurized fluid at a desired tire pressure from a fluid pressure source on a vehicle during operation of the vehicle, a first port configured for sealed communication with a first vehicle tire, and a second port configured for sealed communication with a second vehicle tire;
• a first one-way valve disposed in the valve body between the fluid chamber and the first port so as to allow one-way fluid communication from the fluid chamber to the first port when the first one-way valve opens;
• a second one-way valve disposed in the valve body between the fluid chamber and the second port so as to allow one-way fluid communication from the fluid chamber to the second port when the second one-way valve opens;
• and
• a two-way valve disposed in the valve body between the first port and the second port, the two-way valve being configured to remain closed so as to prevent two-way fluid communication between the first port and the second port at or below a first fluid pressure, and to allow the two-way fluid communication at or above a second fluid pressure, the second fluid pressure greater than the first fluid pressure.
