10. A dual tire assembly comprising:
-
a first tire defining a first interior space; a first inlet passage having a first end communicating with the first interior space and having a second end; a second tire defining a second interior space; a second inlet passage having a first end communicating with the second interior space and having a second end; a pair of check valves respectively located at the second ends of the first and second inlet passages, said check valves being respectively and independently movable between an open Position wherein the check valves afford respective flows of air through the first and second passages to the first and second interior spaces; and a flow regulator defining a flow passage communicable between the first and second passages for conducting therethrough a flow of air, the flow passage having a first end communicating with the first passage intermediate the first and second ends of the first passage, and the flow passage having a second end communicating with the second passage intermediate the first and second ends of the second passage, the flow regulator having a valve housing defining a bore, a valve member housed in and supported by the bore for movement between an open position wherein the flow passage is open and the valve member affords passage of a flow of air through the flow passage and a first closed position wherein the flow passage is closed and the valve member prevents flow of air through the flow passage, the flow regulator providing a first pressure surface exposed to pressure in the first passage and providing a second pressure surface exposed to pressure in the second passage, the valve member being in the open position when the pressure differential acting on the first and second pressure surfaces is between zero and a threshold pressure, and the valve member being in the closed position when the pressure differential exceeds the threshold pressure. - View Dependent Claims (11, 12, 13, 14)

15. A dual tire assembly comprising:
-
a first tire defining a first interior space; a second tire defining a second interior space; and a tire pressurization assembly including a manifold having a first inlet, a first valve in the first inlet, a first chamber communicable with the first inlet and the first interior space, a second inlet, a second valve in the second inlet, a second chamber communicable with the second inlet and the second interior space, a by-pass passage communicating between the first and second chambers, the by-pass passage communicating with the first chamber intermediate the first inlet and the first interior space and communicating with the second chamber intermediate the second inlet and the second interior space, and a flow regulator having a valve housing defining a bore communicating with the by-pass passage, a valve member housed and supported by the bore for movement between an open position wherein the by-pass passage is open and affords passage of a flow of air through the by-passage between the first and second interior spaces and a closed position wherein the by-pass passage is closed and prevents flow of air through the by-pass passage, the flow regulator providing a first pressure surface exposed to pressure in the first passage and providing a second pressure surface exposed to pressure in the second passage, the valve member being in the open position when the pressure in the first and second passages exceeds a predetermined threshold pressure and the valve member moving into the closed position when the pressure in either the first passage or the second passage falls below the predetermined threshold pressure. - View Dependent Claims (16, 17, 18, 19, 20)
