ABSTRACT:
The device for indication of low pressure in tire inflation includes a hose which can be connected to the valve stem of the tire for communicating with the compressed air therein. A body is connected to and is in communication with the interior of the hose for receiving compressed air therefrom. An indicator is pivotably attached to the body remote from the hose. An actuating mechanism is disposed in the body and is responsive to the pressure of the compressed air for selectively holding the indicator in a first position during normal operation, and releasing the indicator, upon a drop in the pressure of the compressed air below a predetermined level, to allow the indicator to pivot and assume a second, low-pressure position. A spring is provided for effecting the pivotal movement of the indicator to the second, low-pressure position upon release of the indicator by the actuating mechanism.
