Abstract:
1. A tire pressure regulator assembly comprising: a body assembly including an air inlet adapted to receive a conventional air nozzle and an air outlet adapted to connect to a conventional tire stem, the body assembly defining a vent port; a two-position valve within the body assembly and including a flexible diaphragm supported by the body assembly, the valve having a first position directing air from the air inlet to only the air outlet, the valve having a second position different from the first position directing air from the air inlet to only the vent port, the valve being stable only in the first and second positions, the valve moving from the first position to the second position when the air pressure at the air outlet achieves a predetermined level, wherein the diaphragm is biased toward the first position and is responsive to air pressure at the air outlet to move the valve to the second position in a snap action when the air pressure achieves the predetermined level, wherein the two-position valve prevents the flow of air from the air outlet to the vent port in the first position and in the second position; and an elongate guide defining an internal guide bore and an external guide surface, wherein: air is directed through the internal guide bore and then to the air outlet when the valve is in the first position, and air is directed along the external guide surface and then to the vent port when the valve is in the second position.
