    Abstract: A vehicle air system (300) for a vehicle equipped with a source of pressurized fluid (302, 306), an air brake system (314), a central tire inflation system (316) and a central tire inflation system pressurized fluid reservoir (336) is provided. Preferably, the central tire inflation system reservoir is defined in part by the vehicle spare tire. The central tire inflation system rservoir is fluidly connected to the source of pressurized fluid, the vehicle air brake system and the central tire inflation system by a pair of parallel conduits (332, 334), one of which is provided with a one way check valve (340) allowing pressurized fluid stored in the reservoir to be supplied to the brake system of the central tire inflation system.

    Abstract: A highly accurate pressure control system (200) adapted to control fluid pressure in apparatus such as the air pressure in vehicle tires (136) comprises a control module (210) having an air pressure selector (211) for selecting a desired air pressure and a pressure to voltage transducer circuit (230) for generating a signal representative of the actual air pressure. Signals representative of the difference between actual and desired air pressure are applied to comparator circuitry (246, 248) which control output switches (254, 256) for activating an inflate/deflate valve (220) to inflate or deflate the tires (136) so as to achieve and maintain the desired air pressure. Various circuitry of the control module (210) employ reference signals maintained at reference values held constant relative to a common power supply voltage instead of to a ground reference (218), thus minimizing circuit count and power dissipation while providing sufficient current for operating output switches (254, 256).

    Abstract: An automatic tire inflation/deflation system for a vehicle (10) is disclosed. Air passageways for the pressurize air are provided internally through the wheel assemblies without cutting into load bearing members. A rotating seal is provided by way of a pair of sealing rings (52,54) located inboard of the hub bearings (32,33) to protect the seals from adverse environmental conditions. A kit for retrofitting vehicles to include an automatic tire inflation/deflation system is also disclosed. Ramp surfaces (90, 91, 92) formed in the hub (30') are provided to facilitate removal of the bearing assemblies (32, 33).

    Abstract: An air delivery system is operable to on-board compressed air to an associated work vehicle from an associated or auxiliary source such as for example an external large compressor or air storage tank for assisting a tire inflation system (TIS) of the associated work vehicle to expedite tire inflation particularly when transitioning to a desired raised tire pressure, and is further operable to off-board compressed air from a compressor of the TIS system on-board the associated work vehicle for delivery from the TIS to an associated or external compressed air consuming device such as an implement attached with the associated work vehicle or the like. A bi-directional air delivery retrofit kit provides on-boarding and off-boarding of an extra-vehicular compressed air product relative to an associated work vehicle. A dual source air delivery system provides pressurized air to an air storage device from on-board and off-board pressurized air sources.
