ABSTRACT:
A multiple-function valve cap is disclosed for mounting on a valve stem of a tire for indicating a safe pressure condition or a low pressure warning. The multiple-function valve cap includes a pressure indicator assembly having a piston including a safe pressure indicator, and an internal bore. A warning indicator is seated within the internal bore of the piston. A biasing spring is fitted between the low pressure warning indicator and the safe pressure indicator, and acts to urge them apart, such that the warning indicator is displayed when low pressure is applied to the piston. When a safe level of air pressure is applied to the piston, the piston is moved against the force of the biasing spring to surround the warning indicator, and the safe pressure indicator is displayed.
