A utility vehicle having a chassis on which a tire inflation system is configured to be arranged, wherein the chassis has at least one axle with a cavity which is embodied as a compressed-gas reservoir in which a gas at a specified gas pressure is stored for inflating a tire of the utility vehicle with the gas, wherein the compressed-gas reservoir has a wall with a compressive strength of at least 0.9 N/mm2, preferably at least 1.4 N/mm2.

A tire inflation system is provided for a vehicle supported by a plurality of inflatable tires. The system includes a compressor carried on the vehicle, and an air storage tank carried on the vehicle and connected to the compressor for storing compressed air. A plurality of automatically operable fill valves are provided, each fill valve being associated with a respective one of the tires so that each tire is communicated with the air storage tank via a separate one of the fill valves to increase inflation pressure in the tire when its respective fill valve is in an open position. A controller is operably associated with all of the fill valves. The controller has a multiple tire rapid inflation mode in which the fill valves associated with at least two of the tires are maintained in their open positions for an initial period until pressure in the air storage tank and the at least two tires substantially equalizes, and for a subsequent period during which the compressor provides additional inflation air to the at least two tires.

An onboard inflation system for a vehicle such as an agricultural vehicle is disclosed, including a tire mounted on a wheel to form a wheel and tire assembly. The tire includes a tread portion and a tire cavity including an inflation chamber adjacent the tread portion of the tire. A storage chamber is carried by at least one of the wheel and the tire. A compressor arrangement is communicated with both the storage chamber and the inflation chamber. The compressor arrangement is configured to transfer air between the storage chamber and the inflation chamber.

A tire inflation system is provided for a vehicle supported by a plurality of inflatable tires. The system includes a compressor, a main air storage tank and an auxiliary air storage tank. An automated shut off valve is disposed between the main air storage tank and the auxiliary air storage tank. An inflation sensor is arranged to detect an inflation pressure provided to the tires. A controller has a rapid inflation mode configured to initially communicate stored compressed air from both the main air storage tank and the auxiliary air storage tank to the tire or tires being inflated, and to then close the automated shut off valve so that additional compressed air from the compressor is communicated to the tire or tires being inflated without repressurizing the auxiliary air storage tank.

A method and a system are provided for adjusting a pressure of a medium to a target pressure. The method includes: providing a pneumatic structure in which the medium is at a medium pressure that is a starting pressure; providing an adsorptive material operable within a range of temperatures that is proportionate with a range of medium pressures at which the pneumatic structure is operable; and adjusting a temperature of the adsorptive material to effect an adjustment of the medium pressure to the target pressure for performing a selected function. The system performs the method and includes the absorptive material and at least one regulator for adjusting the temperature of the adsorptive material.

A device for maintaining and changing the pressure in a is provided whereby the inner pressure space of the tire is connected through a pump to a pressure accumulator which, at its input and/or output into the inner pressure space of the tire, is fitted with at least one pressure control element. The pump can be a peristaltic pump in the shape of a deformable hose placed on the perimeter of the tire, fitted with an air inlet and an air outlet, while the air inlet and the air outlet are positioned on the perimeter of the tire distant from each other by a preset length, dependent on the deformation of the tire.
