A device for program-controlled variation of the composition of a gaseous mixture for inflating a tire for performing the method, comprising a first source of at least one main gas, a second source of at least one additional gas, at least one first compressor suitable for compressing to a preset pressure a gaseous mixture of at least said main gas and additional gas, at least one dispenser of compressed mixture which is connected to the delivery of said compressor, and further comprising at least one mixer for said at least one main gas and said at least one additional gas which is suitable for delivering a gaseous mixture having a desired composition, a gas analyzer means arranged downstream of said mixer, valve means for controlling the flow between said mixer and said first and second gas sources, and program control means arranged to control said valve means in response to control signals from said analyzer means.
A tire inflator, comprising a compressor, at least one inflating nozzle or gun arranged to be connected to an inflation inlet for a tire, a source of deoxygenated or oxygen-depleted air located upstream of said compressor and downstream of said inflation nozzle or nozzles, and means for changing the composition of the air used to inflate the tire according to a preset inflation pressure for the tire including means for decreasing the percentage of oxygen (O2) as the inflation pressure required for the tire increases.
An inflation method, wherein the composition of the air used to inflate a tire is changed according to a preset inflation pressure for said tire, and comprising decreasing the percentage of oxygen (O2) as the inflation pressure required for the tire increases.
A device for program-controlled variation of the composition of a gaseous mixture for inflating a tire wherein the composition of the air used to inflate said tire is changed according to a preset inflation pressure for said tire, compromising a first source of at least one main gas, a second source of at least one additional gas, at least one first compressor suitable for compressing to a preset pressure a gaseous mixture of at least said main gas and additional gas, at least one dispenser of compressed mixture which is connected to the delivery of said compressor, and comprising at least one mixer for said at least one main gas and said at least one additional gas which is suitable for delivering a gaseous mixture having a desired composition, a gas analyzer means arranged to control said valve means in response to control signals from said analyzer means.
