Abstract
Disclosed herein are valve assemblies, such as for use in a tire inflation system, the valve assemblies comprising: a first fluid port and a second fluid port fluidly connectable with one another via a fluid passage; a first valve having an open position and a closed position, the first valve in its closed position blocking the fluid passage and in its open position unblocking the fluid passage; a second valve having an open position and a closed position, the second valve in its closed position blocking the fluid passage and in its open position unblocking the fluid passage; and a control volume fluidly connected or fluidly connectable with the first fluid port via a flow restrictor, wherein the first valve, the second valve and the control volume are configured such that a fluid pressure in the control volume biases each of the first valve and the second valve toward their closed position.
