Abstract
A quick disconnect pressure relief valve for a tire mounted on a rim includes a manually operated on/off valve mountable on the rim to provide a discrete pneumatic path between the tire interior and the outer atmosphere. The on/off valve is normally closed. A normally closed pressure operated valve insertable into the on/off valve opens the on/off valve to the passage of air through the inserted pressure operated valve to the exterior atmosphere. A plurality of such pressure operated valves calibrated to release air at different preselected tire pressure levels may be interchanged in the on/off valve. A latch is provided for securing the selected pressure operated valve in the manually operated on/off valve. Thus, to rapidly change the tire pressure level, the user need only insert a pressure operated valve calibrated to the desired tire pressure into the manually operated on/off valve. In a preferred embodiment of the invention, each pressure operated valve includes an adjustable bias by which the user can preset its particular pressure level. By using a plurality of such pressure operated valves with the manually operated on/off valve, the user can preset any number of pressure operated valves to provide a wide range of preselected pressure levels for the tire.
