Patent attributes
A device for removing excess air pressure from a valve stem of a tire of a vehicle having a body with a cavity, an intake port for forming a fluid-tight seal with, extracting compressed air through the valve stem, located near the input end of the body, and conveying the air to the cavity; a control mechanism for selecting a desired magnitude of air pressure; a pressure-measuring mechanism for determining the magnitude of air pressure in the cavity; a display mechanism for displaying the selected magnitude of air pressure; and a release mechanism with a release valve and an exhaust port. The release mechanism has an opened configuration wherein the release valve allows compressed air from the cavity to freely escape through the exhaust port when the magnitude of air pressure in the cavity is greater than the selected magnitude of air pressure, and a closed configuration wherein the release valve prevents compressed air from the cavity from escaping through the exhaust port when the magnitude of air pressure in the cavity is less than the selected magnitude of air pressure.
