Abstract
A tire inflation system includes a hose that connects to a tire via a valve stem. A control valve is in fluid communication with the hose and senses when pressure falls below a predetermined minimum value. When this occurs, the control valve automatically opens to re-supply air to the tire until the predetermined minimum value is achieved. A pressure relieve valve is also in fluid communication with the hose. If, for example, ambient temperatures increase, causing tire pressure to increase, then the pressure relief valve automatically vents excessive pressure to atmosphere. The pressure relief valve is set at a predetermined maximum pressure level that is generally at least 5 psi more than the predetermined minimum value.
