Low pressure tire warning device

摘要

A low pressure tire valve assembly having a standard tire valve core unit encapsulated at its lower end into a flexible rubber plug which has molded to it a distensible cylindrical member which biases a plurality of circumferentially spaced springs into latching engagement with an indicator cap. The indicator cap is ejected by spring means upon a loss of pressure due to collapse of the distensible member. Cord means interconnects the cap to the tire valve assembly.
